1 00:00:05,280 --> 00:00:09,120 Speaker 1: Hey, Doc, I've been thinking I need a new blood. Oh, 2 00:00:09,160 --> 00:00:13,320 Speaker 1: the animal blood it's not working. Yeah, I tried it. 3 00:00:13,320 --> 00:00:15,560 Speaker 1: It made me crash my car, made me feel you know, 4 00:00:15,600 --> 00:00:18,960 Speaker 1: about three feet thick. Well what about true blood? Just 5 00:00:19,079 --> 00:00:23,440 Speaker 1: hit the market? Headache, dry mouth, made my eyes too red. Well, 6 00:00:23,600 --> 00:00:27,520 Speaker 1: there's currently a clinical trial for something called day Breaker. 7 00:00:27,760 --> 00:00:29,479 Speaker 1: I'll stop you right there, Doc, I got some on 8 00:00:29,520 --> 00:00:32,320 Speaker 1: the black market. Made me vomit and explode. But what 9 00:00:32,440 --> 00:00:35,919 Speaker 1: exactly are you looking for? Well, you know, I don't 10 00:00:35,960 --> 00:00:38,000 Speaker 1: want to go crazy with hunger. I don't want my 11 00:00:38,080 --> 00:00:40,880 Speaker 1: things too long. I also don't want it to spill 12 00:00:41,800 --> 00:00:44,960 Speaker 1: or come in a pill. Now, now you're rhyming again. 13 00:00:45,479 --> 00:00:48,479 Speaker 1: Have you been taking your syntho gore because that's one 14 00:00:48,520 --> 00:00:51,720 Speaker 1: of the withdrawal symptoms. I'm all out, Doc, and I 15 00:00:51,720 --> 00:00:55,560 Speaker 1: don't imagine you have anything else around here on tap, 16 00:00:59,480 --> 00:01:01,800 Speaker 1: welcome to Stuff to Blow Your Mind, production of My 17 00:01:01,920 --> 00:01:11,039 Speaker 1: Heart Radio. Hey you, welcome to Stuff to Blow your Mind. 18 00:01:11,120 --> 00:01:14,119 Speaker 1: My name is Robert lamp and I'm Joe McCormick. And 19 00:01:14,200 --> 00:01:17,920 Speaker 1: here we are covered in blood. That's right. Last year 20 00:01:18,000 --> 00:01:21,039 Speaker 1: we put out a Halloween episode titled I Drink Your 21 00:01:21,040 --> 00:01:25,720 Speaker 1: Blood Type, all about blood types. That you know humans have, 22 00:01:25,880 --> 00:01:28,080 Speaker 1: but with a vampire flavoring. I think we did a 23 00:01:28,080 --> 00:01:30,880 Speaker 1: fun skit at the beginning of that one. Um we 24 00:01:31,040 --> 00:01:34,679 Speaker 1: briefly mentioned synthetic blood in vampire fiction. In that one, 25 00:01:34,680 --> 00:01:38,000 Speaker 1: I remember we did reference true blood as well as 26 00:01:38,040 --> 00:01:42,240 Speaker 1: a nineteen thirty nine film titled The Return of Doctor X, 27 00:01:42,520 --> 00:01:44,679 Speaker 1: which I haven't seen yet. I still haven't seen this one, 28 00:01:44,720 --> 00:01:49,160 Speaker 1: but it stars Humphrey Bogart as an evil doctor with 29 00:01:49,200 --> 00:01:51,240 Speaker 1: this kind of like skunk streak in his hair and 30 00:01:51,400 --> 00:01:55,720 Speaker 1: round glasses who's been brought back to life with synthetic blood. 31 00:01:55,880 --> 00:01:59,320 Speaker 1: The hair suggests elsa Anchester like in bright A Frankenstein. 32 00:01:59,520 --> 00:02:02,280 Speaker 1: It does. Yeah, you definitely can see the Frenstein d 33 00:02:02,400 --> 00:02:06,320 Speaker 1: NA um maybe even the lazy Frankenstein DNA in this 34 00:02:06,600 --> 00:02:09,680 Speaker 1: costume design. Now, in that episode, like you said, we 35 00:02:09,760 --> 00:02:14,160 Speaker 1: mainly ended up talking about natural uh properties of blood types, 36 00:02:14,280 --> 00:02:17,799 Speaker 1: what evolutionary pressures drove the development of different blood types, 37 00:02:18,080 --> 00:02:20,760 Speaker 1: how that functions in medicine, and then I think we 38 00:02:20,800 --> 00:02:24,120 Speaker 1: also talked about some pseudo scientific beliefs about blood types 39 00:02:24,120 --> 00:02:27,880 Speaker 1: and personality and psychology. But I think we only briefly 40 00:02:27,919 --> 00:02:31,800 Speaker 1: mentioned the possibility of synthetic blood or using something other 41 00:02:31,919 --> 00:02:35,200 Speaker 1: than human blood in your veins. Yeah, that's right, we did. 42 00:02:35,200 --> 00:02:37,680 Speaker 1: We didn't get into the topic all that much, and 43 00:02:37,760 --> 00:02:43,080 Speaker 1: subsequently we had some listeners suggested for October twenty fair. 44 00:02:43,200 --> 00:02:46,720 Speaker 1: So here we are now, first and foremost, we should 45 00:02:46,760 --> 00:02:50,320 Speaker 1: really establish what blood literally is and maybe a little 46 00:02:50,320 --> 00:02:54,800 Speaker 1: bit about what it metaphorically is. So blood is technically 47 00:02:54,840 --> 00:02:57,799 Speaker 1: both a fluid and a tissue, since it's made out 48 00:02:57,800 --> 00:03:02,280 Speaker 1: of similar specialized cells bended in a liquid matrix of plasma. 49 00:03:02,840 --> 00:03:06,160 Speaker 1: It carries oxygen and nutrients to the cells and carries 50 00:03:06,160 --> 00:03:09,800 Speaker 1: off carbon dioxide and other waste products. The heart pumps 51 00:03:09,800 --> 00:03:12,400 Speaker 1: it through the body, but it's also part of the 52 00:03:12,480 --> 00:03:15,800 Speaker 1: larger circulatory system, so organs like the kidney and the 53 00:03:15,880 --> 00:03:18,680 Speaker 1: lung are also important to blood. And of course, if 54 00:03:18,680 --> 00:03:21,080 Speaker 1: we lose enough blood in a short enough period of time, 55 00:03:21,520 --> 00:03:24,320 Speaker 1: we die, as we all know. Yes, uh, And it's 56 00:03:24,400 --> 00:03:27,440 Speaker 1: it's amazing to stop and think how blood is not 57 00:03:27,520 --> 00:03:31,760 Speaker 1: just in your body, but constantly moving throughout it, you know, 58 00:03:31,840 --> 00:03:34,960 Speaker 1: like while you're alive, it never stops. This is one 59 00:03:35,000 --> 00:03:38,120 Speaker 1: of those ideas that sometimes makes me feel the you know, 60 00:03:38,160 --> 00:03:40,520 Speaker 1: the flame run under my skin. It's it's just a 61 00:03:40,520 --> 00:03:43,440 Speaker 1: little too creepy thinking about how even when I'm sitting 62 00:03:43,480 --> 00:03:47,440 Speaker 1: perfectly still and perfectly at rest, the blood is still going. 63 00:03:47,600 --> 00:03:50,920 Speaker 1: It's rushing through every inch of me. And that's true 64 00:03:50,960 --> 00:03:52,520 Speaker 1: for all of us, of course, And so one thing 65 00:03:52,560 --> 00:03:55,080 Speaker 1: I was wondering, actually is how long does it take 66 00:03:55,160 --> 00:03:57,960 Speaker 1: for each red blood cell to circulate all the way 67 00:03:57,960 --> 00:04:00,600 Speaker 1: through your body and make it back to the heart. Uh. 68 00:04:00,800 --> 00:04:02,840 Speaker 1: I was reading an interesting Q and A by the 69 00:04:02,920 --> 00:04:05,240 Speaker 1: Naked Scientists where they worked out the math on this, 70 00:04:05,360 --> 00:04:07,960 Speaker 1: and I thought this was pretty cool. So it depends 71 00:04:07,960 --> 00:04:10,720 Speaker 1: on a number of factors. But their estimate was that 72 00:04:10,800 --> 00:04:15,040 Speaker 1: for most people, the body performs a complete blood circuit 73 00:04:15,280 --> 00:04:19,200 Speaker 1: roughly every minute. And they found this because the average 74 00:04:19,200 --> 00:04:22,080 Speaker 1: adult has, you know, roughly five leaders of blood in 75 00:04:22,120 --> 00:04:25,479 Speaker 1: the body. The average heart pumps about seventy milli leaders 76 00:04:25,520 --> 00:04:28,320 Speaker 1: of blood every time it beats, and the average resting 77 00:04:28,440 --> 00:04:31,200 Speaker 1: heart rate is something like seventy beats per minute. And 78 00:04:31,200 --> 00:04:33,719 Speaker 1: if you multiply all these together, you find that the 79 00:04:33,760 --> 00:04:36,840 Speaker 1: heart circulates about four point nine are close to five 80 00:04:36,920 --> 00:04:40,480 Speaker 1: leaders of blood every minute. So on average, it probably 81 00:04:40,480 --> 00:04:43,520 Speaker 1: takes about one minute for your heart to circulate your 82 00:04:43,760 --> 00:04:47,560 Speaker 1: entire blood volume. And it does this minute after minute 83 00:04:47,839 --> 00:04:51,640 Speaker 1: after minute until you die. Isn't that crazy the longer 84 00:04:51,680 --> 00:04:54,359 Speaker 1: you look at it. Yeah, this idea of this endless 85 00:04:54,480 --> 00:04:58,480 Speaker 1: river of blood just circulating through your body. Now, blood, 86 00:04:58,600 --> 00:05:03,000 Speaker 1: of course, also has taken on various UH additional connotations, 87 00:05:03,480 --> 00:05:09,200 Speaker 1: connotations of heredity, class, race, violence, sacrifice, and more. I 88 00:05:09,240 --> 00:05:13,320 Speaker 1: was reading an article titled bio Securitization, the Quest for 89 00:05:13,400 --> 00:05:17,240 Speaker 1: Synthetic Blood and the Taming of Kinship by Cath Weston. 90 00:05:17,760 --> 00:05:20,320 Speaker 1: The author gets gets a bit deeper into the connotations 91 00:05:20,320 --> 00:05:23,440 Speaker 1: that will be discussing today, but there were several aspects 92 00:05:23,440 --> 00:05:26,000 Speaker 1: worth highlighting. First of all, just the idea of royal 93 00:05:26,040 --> 00:05:28,919 Speaker 1: blood and the divine right of kings, the idea that 94 00:05:28,960 --> 00:05:32,680 Speaker 1: there's like literally there's something in the bloodline, UM, the 95 00:05:32,720 --> 00:05:35,839 Speaker 1: idea of blood is a signifier of kinship, the idea 96 00:05:35,880 --> 00:05:39,200 Speaker 1: of the idea that your relatives are your blood relatives, etcetera, 97 00:05:39,920 --> 00:05:42,280 Speaker 1: and UH. An interesting thing that Weston points out to 98 00:05:42,520 --> 00:05:46,479 Speaker 1: is a historical tidbit is that blood transfusion UH during 99 00:05:46,480 --> 00:05:49,880 Speaker 1: its history has been objected to for both religious reasons 100 00:05:49,920 --> 00:05:51,680 Speaker 1: and we'll get into an example of that in a bit, 101 00:05:51,920 --> 00:05:56,480 Speaker 1: but also for reasons steeped in racist ideologies. UM. And 102 00:05:56,520 --> 00:05:59,400 Speaker 1: so the you know, the the metaphorical idea of blood 103 00:05:59,560 --> 00:06:03,679 Speaker 1: has often seemed to muddy our biological understanding of blood. 104 00:06:04,000 --> 00:06:05,719 Speaker 1: I think what this comes down to is that in 105 00:06:05,800 --> 00:06:08,800 Speaker 1: many ways, blood is seen as some kind of essence. 106 00:06:09,000 --> 00:06:11,200 Speaker 1: That it's not just a part of the body that 107 00:06:11,520 --> 00:06:14,640 Speaker 1: plays a particular role in um in energy and the 108 00:06:14,680 --> 00:06:17,800 Speaker 1: oxygenation of tissues and the removal of waste products and 109 00:06:17,839 --> 00:06:20,600 Speaker 1: the circulation of chemicals, hormones and things throughout the body. 110 00:06:20,680 --> 00:06:25,200 Speaker 1: But it also is somehow the soul of the thing. 111 00:06:25,560 --> 00:06:30,240 Speaker 1: It There are properties inherent to the animal or the 112 00:06:30,320 --> 00:06:34,479 Speaker 1: human that are represented by or borne through the blood 113 00:06:34,520 --> 00:06:37,880 Speaker 1: in particular. Yeah, it gets kind of weird when you 114 00:06:37,880 --> 00:06:39,960 Speaker 1: think about the fact that, like, on one hand, to 115 00:06:40,040 --> 00:06:42,240 Speaker 1: think that the blood is not us, that the blood 116 00:06:42,320 --> 00:06:45,120 Speaker 1: is just this this oil that we run on, Like 117 00:06:45,200 --> 00:06:48,200 Speaker 1: that's that's not completely correct. Like the blood we we 118 00:06:48,240 --> 00:06:50,080 Speaker 1: are blood, the blood is part of our body again, 119 00:06:50,080 --> 00:06:53,520 Speaker 1: it's it's tissue and a liquid. But on the other hand, 120 00:06:53,680 --> 00:06:55,800 Speaker 1: it were not just the blood. It's not like if 121 00:06:55,800 --> 00:06:57,719 Speaker 1: you drained our blood out and put us in a jar, 122 00:06:57,880 --> 00:07:01,000 Speaker 1: that's not us in the jar and empty shell over here. 123 00:07:01,120 --> 00:07:05,080 Speaker 1: Like I'm I'm reminded of of myths, for instance, that 124 00:07:05,200 --> 00:07:08,839 Speaker 1: involve something like blood in other beings, like the the 125 00:07:08,880 --> 00:07:12,680 Speaker 1: episode we did on Tallos the Bronze automaton and the 126 00:07:12,720 --> 00:07:14,760 Speaker 1: idea that he had this I corp in his body 127 00:07:14,880 --> 00:07:18,840 Speaker 1: that was like the magical substance that that made him function, 128 00:07:19,240 --> 00:07:22,840 Speaker 1: and that that reveals a lot about how blood was 129 00:07:22,840 --> 00:07:25,640 Speaker 1: was considered in prior ages. Yeah, it's like the oil 130 00:07:25,680 --> 00:07:29,280 Speaker 1: and the car engine, but it's also the it's somehow magical, 131 00:07:29,400 --> 00:07:32,680 Speaker 1: it's somehow bearing the properties of godhood. And when you 132 00:07:32,720 --> 00:07:34,960 Speaker 1: take out the plug and allow all of the I 133 00:07:35,080 --> 00:07:37,040 Speaker 1: cord to drain out, he just kind of comes to 134 00:07:37,080 --> 00:07:40,320 Speaker 1: a halt. Yeah. So indeed, like the idea of taking 135 00:07:40,360 --> 00:07:42,800 Speaker 1: the blood from one person, the blood that is part 136 00:07:42,840 --> 00:07:45,840 Speaker 1: of that person, in putting it into another person, you 137 00:07:45,880 --> 00:07:48,080 Speaker 1: know that that that opens up the door for a 138 00:07:48,080 --> 00:07:51,240 Speaker 1: lot of you know, I guess, uh, you know, metaphorical 139 00:07:51,320 --> 00:07:53,440 Speaker 1: ideas about what that means. What does it mean that 140 00:07:53,440 --> 00:07:57,000 Speaker 1: that person is now in me um or what orient 141 00:07:57,080 --> 00:07:58,920 Speaker 1: in the when there's an injury, What does it mean 142 00:07:58,920 --> 00:08:01,000 Speaker 1: that a lot of me is an out like on 143 00:08:01,040 --> 00:08:04,400 Speaker 1: the pavement. That sort of thing. Now that brings us 144 00:08:04,440 --> 00:08:06,640 Speaker 1: to what we're mainly going to be talking about today 145 00:08:06,520 --> 00:08:09,800 Speaker 1: the idea of blood transfusions. Again, if you lose too 146 00:08:09,880 --> 00:08:12,600 Speaker 1: much blood in a short period of time, you can die. 147 00:08:12,760 --> 00:08:14,760 Speaker 1: One way that we know that that can be prevented 148 00:08:14,960 --> 00:08:19,000 Speaker 1: today is by adding more blood, assuming it is the 149 00:08:19,000 --> 00:08:22,320 Speaker 1: correct sort of blood. When a blood transfusion is done correctly, 150 00:08:22,600 --> 00:08:25,680 Speaker 1: can save lives. It's you know, this is I think 151 00:08:25,760 --> 00:08:28,480 Speaker 1: something that most of us are familiar with. UH and 152 00:08:28,480 --> 00:08:31,320 Speaker 1: as we detailed in last year's episode, which I think 153 00:08:31,360 --> 00:08:35,240 Speaker 1: we recently re ran in our feed UH, one does 154 00:08:35,320 --> 00:08:37,800 Speaker 1: have to get it just right to respect the different 155 00:08:37,800 --> 00:08:41,120 Speaker 1: blood types and this was a significant hurdle to overcome 156 00:08:41,360 --> 00:08:45,720 Speaker 1: in medical science totally. But the idea of synthetic blood 157 00:08:46,000 --> 00:08:48,160 Speaker 1: or a blood substitute, you know, the idea of there 158 00:08:48,200 --> 00:08:50,840 Speaker 1: being something other than blood that you could fill one 159 00:08:50,920 --> 00:08:55,880 Speaker 1: up with when you're you're facing a life threatening shortage. UM. 160 00:08:55,960 --> 00:08:59,200 Speaker 1: The key argument here would be, you know, something could 161 00:08:59,240 --> 00:09:02,280 Speaker 1: be manufactured it ahead of time and some degree kept 162 00:09:02,320 --> 00:09:05,240 Speaker 1: on a shelf for use in times of emergency. So 163 00:09:05,520 --> 00:09:07,920 Speaker 1: this was you know, just decreasing to some extent the 164 00:09:08,000 --> 00:09:11,400 Speaker 1: reliance on blood and tissue donation. UM. I think it's 165 00:09:11,440 --> 00:09:13,200 Speaker 1: also been argued that this would be ideal if you 166 00:09:13,240 --> 00:09:16,560 Speaker 1: were dealing with a very far flung situation. You can't 167 00:09:16,600 --> 00:09:19,120 Speaker 1: have a proper blood bank on hand, but perhaps you 168 00:09:19,160 --> 00:09:21,240 Speaker 1: have some sort of short term substitute that can be 169 00:09:21,320 --> 00:09:23,319 Speaker 1: used instead. But of course, the other side of the 170 00:09:23,360 --> 00:09:26,440 Speaker 1: scenario is that such blood would be a product not 171 00:09:26,559 --> 00:09:29,840 Speaker 1: unlike true blood from the TV show that we mentioned earlier. 172 00:09:30,480 --> 00:09:33,880 Speaker 1: We'll discuss where we are in our quest for a 173 00:09:34,160 --> 00:09:37,040 Speaker 1: true blood substitute, but first we want to explore some 174 00:09:37,080 --> 00:09:39,760 Speaker 1: of the earliest and really some of the weirdest and 175 00:09:39,760 --> 00:09:45,080 Speaker 1: grossest ideas for synthetic blood. It's really a wonderfully bizarre 176 00:09:45,440 --> 00:09:47,800 Speaker 1: bit of history. So one of the sources I was 177 00:09:47,840 --> 00:09:51,880 Speaker 1: looking at here is titled Artificial Blood by Suma and Sarkar, 178 00:09:52,280 --> 00:09:54,160 Speaker 1: and it was published in two thousand and eight by 179 00:09:54,160 --> 00:09:57,520 Speaker 1: the Indian Journal of Critical Care Medicine. And in this 180 00:09:57,640 --> 00:10:00,280 Speaker 1: the author points out that the notion of artificial blood 181 00:10:00,400 --> 00:10:02,600 Speaker 1: has pretty much stirred in the human mind for as 182 00:10:02,640 --> 00:10:05,679 Speaker 1: long as people have bled to death from their injuries. 183 00:10:05,720 --> 00:10:09,600 Speaker 1: Like we've we've realized that there's something and and this 184 00:10:09,679 --> 00:10:11,400 Speaker 1: can get kind of, I think, kind of vague and 185 00:10:11,440 --> 00:10:13,959 Speaker 1: magical as to the you know, the idea that blood 186 00:10:14,360 --> 00:10:17,440 Speaker 1: is important and if we lose it we can die, 187 00:10:17,760 --> 00:10:21,440 Speaker 1: and hey have its loss means death. Perhaps it's uh, 188 00:10:22,400 --> 00:10:25,880 Speaker 1: to add blood is to add life or to restore it. Now, 189 00:10:25,960 --> 00:10:28,360 Speaker 1: certainly there's a there's a mix of magic and myth 190 00:10:28,559 --> 00:10:31,599 Speaker 1: and early medicine here. Uh. Sarkar points to ink and 191 00:10:31,679 --> 00:10:36,760 Speaker 1: folklore depicting something arguably like blood transfusion. I've also seen 192 00:10:36,800 --> 00:10:41,960 Speaker 1: it pointed out elsewhere that Odysseus temporarily resuscitates underworld shades 193 00:10:42,000 --> 00:10:46,280 Speaker 1: by offering them um blood sacrifice in the Odyssey. The 194 00:10:46,320 --> 00:10:50,120 Speaker 1: idea of blood as if not a biological underpinning of life, 195 00:10:50,360 --> 00:10:52,560 Speaker 1: you know, something tied up with our conception of the 196 00:10:52,600 --> 00:10:57,200 Speaker 1: life force. That that passage in the Odyssey is pretty stirring. 197 00:10:57,200 --> 00:11:00,280 Speaker 1: I was looking at a Robert Fagel's translation of it, 198 00:11:00,840 --> 00:11:05,359 Speaker 1: and basically, Odysseus is instructed to um to to flay 199 00:11:05,400 --> 00:11:08,439 Speaker 1: and then burn these um the the the animals and 200 00:11:08,480 --> 00:11:11,480 Speaker 1: sacrificial rams or what have you, in order to like 201 00:11:11,600 --> 00:11:13,880 Speaker 1: draw in the spirits of the dead so that he 202 00:11:13,920 --> 00:11:16,199 Speaker 1: can commune with them. And then of course later on 203 00:11:16,679 --> 00:11:19,360 Speaker 1: he does it. Uh. And it's it's it's actually really 204 00:11:19,480 --> 00:11:22,040 Speaker 1: rather creepy. Yes, and I would say one reason is 205 00:11:22,080 --> 00:11:25,439 Speaker 1: that it contains this older Greek view of the afterlife, 206 00:11:25,480 --> 00:11:28,720 Speaker 1: sort of the pre Platonic view of the afterlife in 207 00:11:28,840 --> 00:11:31,760 Speaker 1: Greek thought, which is less the idea of you know, 208 00:11:32,240 --> 00:11:35,800 Speaker 1: places of possible reward or punishment, and more the idea 209 00:11:35,880 --> 00:11:39,400 Speaker 1: that everyone who dies just dwells forever. In this miserable, 210 00:11:39,520 --> 00:11:44,679 Speaker 1: confused dungeon of shades. All right, on that wonderfully spooky note, 211 00:11:44,720 --> 00:11:46,720 Speaker 1: We're gonna take a quick break, but we'll be right 212 00:11:46,760 --> 00:11:54,960 Speaker 1: back with tales of early blood transfusions. Thank alright, we're 213 00:11:54,960 --> 00:11:58,400 Speaker 1: back now in talking about substitutes for human blood that 214 00:11:58,480 --> 00:12:01,160 Speaker 1: can be hooked up to your veins. One of the 215 00:12:01,280 --> 00:12:04,000 Speaker 1: easiest places you know, you can imagine people would have 216 00:12:04,080 --> 00:12:08,079 Speaker 1: looked is to the blood of other animals. That's right, yeah, 217 00:12:08,200 --> 00:12:10,240 Speaker 1: and uh and and this at this point, we're gonna 218 00:12:10,280 --> 00:12:14,040 Speaker 1: we're gonna move to around uh sixteen sixteen, because that's 219 00:12:14,040 --> 00:12:17,120 Speaker 1: when a man by the name of William Harvey described 220 00:12:17,120 --> 00:12:20,120 Speaker 1: blood circulation, which is going to be key just a 221 00:12:20,200 --> 00:12:22,720 Speaker 1: better understanding of like what's actually going on with blood. 222 00:12:23,280 --> 00:12:27,280 Speaker 1: And in the following years, numerous substances were tried out 223 00:12:27,480 --> 00:12:30,040 Speaker 1: as a stand in for human blood, and the list 224 00:12:30,080 --> 00:12:32,959 Speaker 1: provided by Sarkar in that article I cited earlier is 225 00:12:32,960 --> 00:12:38,600 Speaker 1: pretty horrific. It includes beer, urine, milk, plant resins, and 226 00:12:38,679 --> 00:12:43,400 Speaker 1: of course sheep blood. Now sheep's blood is at least blood, right, 227 00:12:43,600 --> 00:12:45,560 Speaker 1: so at least it has that going for it. And 228 00:12:45,559 --> 00:12:50,359 Speaker 1: and this is known as zeno transfusion. The first documented 229 00:12:50,480 --> 00:12:55,280 Speaker 1: zeno transfusion was conducted by French physicians Jean Baptiste du 230 00:12:55,400 --> 00:12:59,120 Speaker 1: Ni and Paul Imarez in sixteen sixty seven, and it 231 00:12:59,320 --> 00:13:04,720 Speaker 1: apparently successful between a fifteen year old boy and a lamb. Uh. Yeah, 232 00:13:04,960 --> 00:13:08,640 Speaker 1: So this first one was largely reported as successful. I 233 00:13:08,679 --> 00:13:10,840 Speaker 1: think that could be defined in a number of ways, 234 00:13:10,920 --> 00:13:14,440 Speaker 1: depending on what you what you call success. At least 235 00:13:14,480 --> 00:13:17,520 Speaker 1: it was reported that the fifteen year old boy felt 236 00:13:17,559 --> 00:13:22,240 Speaker 1: good afterwards. But this whole saga of Jean Baptiste Denny 237 00:13:22,280 --> 00:13:26,000 Speaker 1: is actually I started looking into this a little bit deeper, 238 00:13:26,040 --> 00:13:29,080 Speaker 1: and the more I looked, the weirder and weirder. God, 239 00:13:29,720 --> 00:13:31,960 Speaker 1: So I want to take a digression here to talk 240 00:13:32,040 --> 00:13:36,160 Speaker 1: about Denny and his his historical context. So one of 241 00:13:36,160 --> 00:13:39,040 Speaker 1: the papers I want to look at is by Benjamin H. 242 00:13:39,120 --> 00:13:42,200 Speaker 1: Chin Ye and I N. H chin Ye, published in 243 00:13:42,240 --> 00:13:45,680 Speaker 1: the Canadian bulletin of medical history in twenty sixteen called 244 00:13:46,000 --> 00:13:50,160 Speaker 1: Blood Transfusion and the Body and Early Modern France. Now, 245 00:13:50,200 --> 00:13:53,480 Speaker 1: a lot of this paper is concerned with what medical 246 00:13:53,640 --> 00:13:58,000 Speaker 1: worldview guided the work of late seventeenth century physicians like 247 00:13:58,120 --> 00:14:02,200 Speaker 1: Denny and Denise contemporaries, and the authors argued that the 248 00:14:02,240 --> 00:14:06,080 Speaker 1: physicians of France in this time did not really have 249 00:14:06,320 --> 00:14:10,160 Speaker 1: a unified system of anatomical theory guiding their work, but 250 00:14:10,360 --> 00:14:15,000 Speaker 1: rather a somewhat contradictory patchwork of contemporary natural philosophy and 251 00:14:15,040 --> 00:14:22,280 Speaker 1: anatomical research with a received background of galenic humoralism. So 252 00:14:22,360 --> 00:14:25,520 Speaker 1: this is the system that you're probably pretty familiar with 253 00:14:25,560 --> 00:14:30,200 Speaker 1: by this time that views health issues as largely related 254 00:14:30,280 --> 00:14:35,520 Speaker 1: to the balance and status of the four humors blood, flim, 255 00:14:35,920 --> 00:14:39,360 Speaker 1: black bile, and yellow bile. This is received from uh, 256 00:14:39,440 --> 00:14:42,640 Speaker 1: not invented by, but sort of shaped and received by 257 00:14:42,680 --> 00:14:46,280 Speaker 1: the Roman physician Galen. Now, the authors of this paper 258 00:14:46,320 --> 00:14:51,160 Speaker 1: tell the story of the first documented zeno transfusion with 259 00:14:51,240 --> 00:14:54,320 Speaker 1: some quotes from the report at the time. As you said, 260 00:14:54,320 --> 00:14:57,120 Speaker 1: the patient was a fifteen year old boy and he 261 00:14:57,160 --> 00:15:01,720 Speaker 1: had already been through twenty round ones of blood letting. 262 00:15:02,440 --> 00:15:06,000 Speaker 1: This was in order quote to assuage the excessive heat 263 00:15:06,800 --> 00:15:10,160 Speaker 1: that was a result of the boy's violent fever. And 264 00:15:10,160 --> 00:15:15,440 Speaker 1: in galenic theory, blood is associated with heat and excitation. 265 00:15:15,760 --> 00:15:17,520 Speaker 1: This is part of the place we get the idea 266 00:15:17,520 --> 00:15:20,640 Speaker 1: of being sanguine, right, you know, having an excess of 267 00:15:20,640 --> 00:15:24,920 Speaker 1: blood makes you sort of a brilliant and excited and energetic. 268 00:15:25,520 --> 00:15:28,960 Speaker 1: But this could be bad in in uh, in galenic thinking, 269 00:15:29,320 --> 00:15:32,680 Speaker 1: by causing fevers, by causing mania, and that sort of thing. 270 00:15:33,080 --> 00:15:36,920 Speaker 1: So they let this guy's blood twenty times, and after 271 00:15:37,000 --> 00:15:41,160 Speaker 1: the twenty bleedings quote, his wit seemed wholly sunk, his 272 00:15:41,320 --> 00:15:45,240 Speaker 1: memory perfectly lost, and his body so heavy and drowsy 273 00:15:45,320 --> 00:15:48,560 Speaker 1: that he was not fit for anything all right. So, 274 00:15:48,680 --> 00:15:51,960 Speaker 1: so basically a situation where the bathtub was too hot. 275 00:15:52,600 --> 00:15:56,160 Speaker 1: Uh let some of the bathwater out. Now it seems 276 00:15:56,200 --> 00:15:58,480 Speaker 1: a bit too cold, right. The problem is that, yeah, 277 00:15:58,520 --> 00:16:01,360 Speaker 1: he's he's appearing sluggish. It seems something is wrong with 278 00:16:01,440 --> 00:16:05,160 Speaker 1: his brain. Maybe he doesn't have memories or much energy. 279 00:16:05,280 --> 00:16:09,840 Speaker 1: Uh So Denny counters this by starting a transfusion. He 280 00:16:09,920 --> 00:16:13,680 Speaker 1: draws blood from the carotid artery of a lamb, and 281 00:16:13,720 --> 00:16:17,800 Speaker 1: then that blood goes into the vein in the boy's arm. Ultimately, 282 00:16:17,880 --> 00:16:21,400 Speaker 1: the boy received about nine ounces of lamb blood, and 283 00:16:21,440 --> 00:16:25,200 Speaker 1: then Denny wrote that quote afterwards, he hath no longer 284 00:16:25,320 --> 00:16:28,960 Speaker 1: that slowness of spirit nor heaviness of body, which before 285 00:16:29,080 --> 00:16:33,240 Speaker 1: rendered him unfit for anything. He grows fat visibly, and 286 00:16:33,320 --> 00:16:36,280 Speaker 1: in brief is a subject of amazement to all those 287 00:16:36,360 --> 00:16:39,800 Speaker 1: that know him and dwell with him. So Danny concludes, Yeah, 288 00:16:39,800 --> 00:16:42,040 Speaker 1: it seems like he's doing good. Uh, And this was 289 00:16:42,080 --> 00:16:47,480 Speaker 1: on June sixty seven. But blood transfusions can be unpredictable. 290 00:16:47,520 --> 00:16:51,360 Speaker 1: There can be wildly different reactions and different patients depending 291 00:16:51,440 --> 00:16:56,200 Speaker 1: on often how the host's immune system in particular responds 292 00:16:56,280 --> 00:16:59,680 Speaker 1: to what's being put into the veins. And as we've 293 00:16:59,680 --> 00:17:01,760 Speaker 1: been taught talking about, despite being on the cutting edge 294 00:17:01,760 --> 00:17:05,840 Speaker 1: of seventeenth century anatomy and new surgical techniques, Denny was 295 00:17:05,920 --> 00:17:08,680 Speaker 1: also still in the grip of Galenism, which had been, 296 00:17:09,200 --> 00:17:11,720 Speaker 1: you know, a dominant force in European medicine since the 297 00:17:11,840 --> 00:17:16,320 Speaker 1: Roman Empire, and which attributed the bulk of medical pathologies 298 00:17:16,400 --> 00:17:21,200 Speaker 1: to imbalances or corruptions in the four humors. And Deny himself, 299 00:17:21,240 --> 00:17:23,920 Speaker 1: he agreed with this. He believed quote, the greatest part 300 00:17:24,040 --> 00:17:27,720 Speaker 1: of our diseases are but results of the distemper and 301 00:17:27,800 --> 00:17:31,880 Speaker 1: corruption of the blood. Now he doesn't say quite every disease, 302 00:17:31,920 --> 00:17:34,639 Speaker 1: but you can imagine he thinks most of them. So like, oh, no, 303 00:17:34,960 --> 00:17:38,280 Speaker 1: you've got arthritis. Uh, your problem is you've got bad blood, 304 00:17:39,119 --> 00:17:42,040 Speaker 1: or you know you've got oh a fever. I think 305 00:17:42,080 --> 00:17:43,879 Speaker 1: that's that's a blood issue. We've got to get some 306 00:17:43,920 --> 00:17:47,919 Speaker 1: of that blood out. And so as a result, he believed, quote, 307 00:17:47,960 --> 00:17:51,959 Speaker 1: the speediest and commonest remedy they have in practice is 308 00:17:52,080 --> 00:17:56,480 Speaker 1: to evacuate the same by phlebotomy. Phlebotomy means blood letting, 309 00:17:56,920 --> 00:18:01,600 Speaker 1: or else refresh it and cool it by juliah. Uh So, 310 00:18:01,640 --> 00:18:04,240 Speaker 1: in other words, if you know, for most diseases, the 311 00:18:04,280 --> 00:18:06,480 Speaker 1: cause is bad blood, and the best treatment is to 312 00:18:06,560 --> 00:18:10,280 Speaker 1: drain the blood out or possibly to give the patient julips. 313 00:18:10,600 --> 00:18:13,119 Speaker 1: The paper doesn't explain what julips means here, so I 314 00:18:13,119 --> 00:18:16,440 Speaker 1: tried to look this up. I think what julips refers 315 00:18:16,480 --> 00:18:20,119 Speaker 1: to here is a flavored drink, for example, rose water 316 00:18:20,320 --> 00:18:22,960 Speaker 1: sweetened with sugar syrup. All right, so this is when 317 00:18:22,960 --> 00:18:25,040 Speaker 1: we talked to say about a mint julip. This is 318 00:18:25,640 --> 00:18:28,080 Speaker 1: the same word. Yeah, I think it was. Later on 319 00:18:28,160 --> 00:18:31,720 Speaker 1: that julip came to often have alcoholic connotations. I think 320 00:18:31,720 --> 00:18:34,240 Speaker 1: at this time it just would have meant a flavored drink, 321 00:18:34,280 --> 00:18:37,080 Speaker 1: not necessarily with alcohol in it. I don't know why 322 00:18:37,119 --> 00:18:39,320 Speaker 1: that is thought to deal with corruption of the blood, 323 00:18:39,640 --> 00:18:41,399 Speaker 1: but that is amazing. You know. Can you imagine you 324 00:18:41,400 --> 00:18:44,480 Speaker 1: show up at the hospital with dingay fever or whatever 325 00:18:44,520 --> 00:18:47,120 Speaker 1: and they're like, you could use some rose water? Yeah, 326 00:18:47,240 --> 00:18:50,199 Speaker 1: Or if the or the two possible treatments on the 327 00:18:50,240 --> 00:18:53,680 Speaker 1: table are bleeding or a sweet drink, it's like, yeah, 328 00:18:54,520 --> 00:18:56,600 Speaker 1: essentially you're gonna have kool aid or they're going to 329 00:18:56,680 --> 00:18:59,240 Speaker 1: drain you into a bucket. Well, it seems like between 330 00:18:59,320 --> 00:19:01,960 Speaker 1: the two, didn't he kind of favored one over the other. 331 00:19:02,040 --> 00:19:04,800 Speaker 1: It seems like he was a bleeder. And yeah that 332 00:19:04,880 --> 00:19:08,800 Speaker 1: that kid had not had twenty julips prior to the lamblood. 333 00:19:08,800 --> 00:19:10,760 Speaker 1: To be fair, I don't know how many julips he had, 334 00:19:10,760 --> 00:19:14,840 Speaker 1: but they did bleed him twenty times. Uh, maybe you 335 00:19:14,880 --> 00:19:17,600 Speaker 1: got a julip every time, who knows. It's like the 336 00:19:17,640 --> 00:19:19,280 Speaker 1: brownie they give you and the when you go to 337 00:19:19,320 --> 00:19:22,199 Speaker 1: donate blood, you know you get brownies. Oh man, I 338 00:19:22,240 --> 00:19:26,080 Speaker 1: get um like peanut butter crackers. Sometimes I get what 339 00:19:26,240 --> 00:19:29,280 Speaker 1: is it? There's a special treat, oh Nutter butters. Sometimes 340 00:19:29,280 --> 00:19:31,800 Speaker 1: there are no I've seen the Nutter butters. Yeah, that 341 00:19:32,000 --> 00:19:35,119 Speaker 1: confirmed in my experience. Like it it forces me to 342 00:19:35,480 --> 00:19:39,840 Speaker 1: equate peanut butter with the blood. Like basically, you know, 343 00:19:39,880 --> 00:19:42,200 Speaker 1: we're thinking about the same thing here. It's like, well, 344 00:19:42,240 --> 00:19:44,360 Speaker 1: I lost some blood, gotta get some peanut butter in there. 345 00:19:44,480 --> 00:19:47,119 Speaker 1: That taste of the Nutter butter or the what is 346 00:19:47,240 --> 00:19:49,600 Speaker 1: it's I was trying to remember the name of the 347 00:19:50,600 --> 00:19:53,280 Speaker 1: little brownie that's got the colorful sprinkle on top that 348 00:19:53,320 --> 00:19:56,440 Speaker 1: they give you sometimes, and Seth chimed in there called 349 00:19:56,440 --> 00:19:59,639 Speaker 1: cosmic brownies. We think, yeah, I've never heard of that. 350 00:19:59,680 --> 00:20:03,800 Speaker 1: I mean, like space I believe Seth space cakes. But 351 00:20:03,840 --> 00:20:05,320 Speaker 1: I don't think you should have one of those after 352 00:20:06,160 --> 00:20:09,600 Speaker 1: blood donation. You should have some space shrimp cocktail after 353 00:20:09,640 --> 00:20:14,080 Speaker 1: blood donation. But anyway, okay, So, so bleedings, bleedings, all 354 00:20:14,119 --> 00:20:17,280 Speaker 1: those bleedings obviously that Denny loves. They can really take 355 00:20:17,359 --> 00:20:19,879 Speaker 1: a toll. As described. You know what happened to this 356 00:20:19,920 --> 00:20:24,760 Speaker 1: fifteen year old so Denise saw blood transfusion from animals 357 00:20:24,800 --> 00:20:28,840 Speaker 1: as a perfect compliment to blood letting, and in his words, 358 00:20:28,880 --> 00:20:32,879 Speaker 1: It's quote the old and corrupt being first evacuated, could 359 00:20:32,880 --> 00:20:36,480 Speaker 1: then make room for the new and pure. So in 360 00:20:36,520 --> 00:20:39,920 Speaker 1: the case of the June sixteen sixty seven transfusion, this 361 00:20:40,000 --> 00:20:42,760 Speaker 1: teenage boy, he's blood twenty times to bring down his fever. 362 00:20:42,840 --> 00:20:45,159 Speaker 1: He's pretty low after that, and then lamb's blood is 363 00:20:45,280 --> 00:20:49,560 Speaker 1: used to revive him with a fresh, clean, non corrupted supply. 364 00:20:50,240 --> 00:20:53,879 Speaker 1: But Denny did not stop there with the xeno transfusions. 365 00:20:54,000 --> 00:20:58,320 Speaker 1: Later that same year, Denny also transfused sheep's blood into 366 00:20:58,320 --> 00:21:01,880 Speaker 1: the veins of a healthy forty five year old sedan chairman. 367 00:21:02,280 --> 00:21:04,200 Speaker 1: Now that means he was one of those guys who 368 00:21:04,240 --> 00:21:06,800 Speaker 1: carries fancy people around in the litter, you know. So 369 00:21:06,840 --> 00:21:08,399 Speaker 1: if you're fancy and you don't want to get your 370 00:21:08,400 --> 00:21:10,760 Speaker 1: boots wet, you can ride in a box where four 371 00:21:10,760 --> 00:21:13,400 Speaker 1: guys carry you on poles. So you have to imagine 372 00:21:13,400 --> 00:21:16,320 Speaker 1: if if this guy is a professional sedan chairman, he's 373 00:21:16,320 --> 00:21:18,919 Speaker 1: probably pretty fit, right, Yeah, he's got to be kind 374 00:21:18,920 --> 00:21:21,400 Speaker 1: of a hoss. And for that reason, I've seen this 375 00:21:21,440 --> 00:21:25,960 Speaker 1: case and the idea that there's no identified cause for it, 376 00:21:25,960 --> 00:21:28,639 Speaker 1: it seems like this was maybe a negative control, just 377 00:21:28,720 --> 00:21:31,600 Speaker 1: like seeing what a transfusion does into a healthy guy, 378 00:21:31,720 --> 00:21:34,760 Speaker 1: and reportedly this guy was fine. And then after that, 379 00:21:34,880 --> 00:21:38,400 Speaker 1: Denis performed a transfusion of Calf's blood on a Swedish 380 00:21:38,440 --> 00:21:42,040 Speaker 1: and nobleman who was dying of an unspecified illness in Paris. 381 00:21:42,720 --> 00:21:45,760 Speaker 1: And the first transfusion this guy got seemed to sort 382 00:21:45,760 --> 00:21:48,640 Speaker 1: of enliven him, bringing him back a bit freshen him up, 383 00:21:48,920 --> 00:21:51,320 Speaker 1: but then he died while in the middle of receiving 384 00:21:51,320 --> 00:21:54,520 Speaker 1: his second transfusion. We don't know why he died. But 385 00:21:54,600 --> 00:21:57,720 Speaker 1: then finally the authors tell the story of how Dennis 386 00:21:57,760 --> 00:22:01,520 Speaker 1: performed again a similar operation on a thirty four year 387 00:22:01,560 --> 00:22:05,600 Speaker 1: old man named Antoine Moroy in an attempt to treat 388 00:22:05,640 --> 00:22:09,520 Speaker 1: a supposed mental illness. I read this case described more 389 00:22:09,560 --> 00:22:13,920 Speaker 1: fully in another paper by James G. Chandler, Teresa L. Chin, 390 00:22:14,080 --> 00:22:17,760 Speaker 1: and Max V. Wool Hour called direct Blood Transfusions in 391 00:22:17,760 --> 00:22:22,000 Speaker 1: the Journal of Vascular Surgery from and I was having 392 00:22:22,040 --> 00:22:26,520 Speaker 1: trouble finding out exactly what Moroy's symptoms were. The main 393 00:22:26,840 --> 00:22:29,960 Speaker 1: report about him. The main symptom that is described is 394 00:22:30,000 --> 00:22:33,840 Speaker 1: that he would quote intermittently disappear from his suburban home 395 00:22:34,240 --> 00:22:38,400 Speaker 1: to indulge in paris Is sensual pleasures. I'm not sure 396 00:22:38,400 --> 00:22:41,040 Speaker 1: if that's actually a symptom of an illness, but right, 397 00:22:41,080 --> 00:22:43,359 Speaker 1: I mean, because certainly that that could go along, that 398 00:22:43,400 --> 00:22:45,800 Speaker 1: could certainly be the practice of one who's suffering from 399 00:22:45,920 --> 00:22:48,560 Speaker 1: a true mental illness. But you know, this could also 400 00:22:48,600 --> 00:22:51,400 Speaker 1: just this could also be a case of sexual addiction 401 00:22:51,640 --> 00:22:53,919 Speaker 1: or they or it could just be you know, merely 402 00:22:53,960 --> 00:22:57,359 Speaker 1: this person had a very you know, exciting sex life, 403 00:22:57,840 --> 00:23:01,480 Speaker 1: and whether they decided to treat yeah, so I don't know, 404 00:23:01,520 --> 00:23:04,119 Speaker 1: but it is widely reported at the time. Everyone says 405 00:23:04,119 --> 00:23:07,760 Speaker 1: he was a known madman. So without any other we 406 00:23:07,880 --> 00:23:10,320 Speaker 1: just have to assume that there is something else going 407 00:23:10,320 --> 00:23:13,840 Speaker 1: on with him, I guess. So. Denny, of course, attributed 408 00:23:13,920 --> 00:23:19,399 Speaker 1: this supposed insanity to humorl imbalance. Deny's solution, well, you've 409 00:23:19,400 --> 00:23:22,080 Speaker 1: got to remove this man's blood and replace it with 410 00:23:22,160 --> 00:23:25,959 Speaker 1: calf's blood, and din he believed that the sweetness and 411 00:23:26,080 --> 00:23:29,760 Speaker 1: freshness of the calf's blood would temper the ardor and 412 00:23:29,800 --> 00:23:34,080 Speaker 1: the boiling of the man's existing blood. So Denny tries 413 00:23:34,160 --> 00:23:37,120 Speaker 1: this out. They bled him of two d ninety milli 414 00:23:37,240 --> 00:23:40,040 Speaker 1: leaders of his own blood, and then they put about 415 00:23:40,080 --> 00:23:42,760 Speaker 1: a hundred and seventy five milli leaders of blood from 416 00:23:42,760 --> 00:23:47,160 Speaker 1: a calf's femoral artery into a vein in Moroy's arm, 417 00:23:47,200 --> 00:23:50,280 Speaker 1: and it was reported that his temperament became more subdued 418 00:23:50,400 --> 00:23:53,520 Speaker 1: by the process. So it was repeated in the presence 419 00:23:53,520 --> 00:23:56,120 Speaker 1: of a number of observing physicians a few days later, 420 00:23:56,880 --> 00:23:59,679 Speaker 1: and the second transfusion did not go as well as 421 00:23:59,720 --> 00:24:03,600 Speaker 1: the first one. Maroy reacted first by he said he 422 00:24:03,640 --> 00:24:06,399 Speaker 1: had lumbar pains, a pain in the lower back, and 423 00:24:06,520 --> 00:24:10,680 Speaker 1: tightness in his chest, and he presented an irregular pulse. 424 00:24:11,240 --> 00:24:14,280 Speaker 1: And then the next day this progressed into vomiting and 425 00:24:14,359 --> 00:24:18,159 Speaker 1: a nose bleed, and maybe most alarmingly, h to quote 426 00:24:18,200 --> 00:24:22,200 Speaker 1: from Denise report, he produced a tall glass of urine, 427 00:24:22,280 --> 00:24:25,919 Speaker 1: as black as if it had been deluded by my fireplace. 428 00:24:27,480 --> 00:24:29,680 Speaker 1: I want to be clear here that it may sound, 429 00:24:29,840 --> 00:24:31,600 Speaker 1: it may come through a little bit like I'm I'm 430 00:24:31,600 --> 00:24:35,400 Speaker 1: purely laughing on my side, but um, this is I'm 431 00:24:35,440 --> 00:24:38,359 Speaker 1: feeling an immense sense of revulsion here. This has just 432 00:24:38,440 --> 00:24:41,440 Speaker 1: giving me the all over. Yeah god, uh So you 433 00:24:41,680 --> 00:24:45,120 Speaker 1: would think this would suggest the transfusion was a bad idea, right, 434 00:24:45,160 --> 00:24:49,639 Speaker 1: that this guy's he's experiencing chest pain, back pain, he's vomiting, 435 00:24:49,720 --> 00:24:53,639 Speaker 1: his nose is bleeding and he's peeing black. Yes, but 436 00:24:53,760 --> 00:24:57,520 Speaker 1: Denny considered it a success, And the reason he considered 437 00:24:57,520 --> 00:25:00,280 Speaker 1: it a success was he interpreted the results of into 438 00:25:00,359 --> 00:25:03,880 Speaker 1: humorl theory. He believed that the black urine was an 439 00:25:03,880 --> 00:25:08,119 Speaker 1: evacuation of excess black bile from the body, which he 440 00:25:08,160 --> 00:25:11,280 Speaker 1: wrote is known to send vapors up into the brain 441 00:25:11,480 --> 00:25:15,159 Speaker 1: which disrupt its function. So, according to Deny, he had 442 00:25:15,200 --> 00:25:18,480 Speaker 1: been mistaken that the problem was too much corrupted blood. Instead, 443 00:25:18,520 --> 00:25:21,800 Speaker 1: the problem was too much corrupted black bile, and the 444 00:25:21,840 --> 00:25:25,720 Speaker 1: transfusion had caused the body to evacuate at all, and 445 00:25:25,800 --> 00:25:30,520 Speaker 1: Dinny believed that his transfusion had somewhat succeeded in curing Moroy. 446 00:25:31,960 --> 00:25:34,080 Speaker 1: It's such a the The history thus far is is 447 00:25:34,160 --> 00:25:37,160 Speaker 1: very fascinating because you know, if you're not familiar with it, 448 00:25:37,280 --> 00:25:40,159 Speaker 1: and you hear about, okay, the first blood transfusion and 449 00:25:40,200 --> 00:25:43,879 Speaker 1: it's going to involve a human and um and and lamb, 450 00:25:44,359 --> 00:25:47,119 Speaker 1: you just assume it's going to end and just disaster 451 00:25:47,280 --> 00:25:49,520 Speaker 1: and just to end in death, and that that will 452 00:25:49,560 --> 00:25:53,359 Speaker 1: be a stumbling block. But then it's not, or seemingly not. 453 00:25:53,720 --> 00:25:55,720 Speaker 1: And then in this case, something that seems like a 454 00:25:55,760 --> 00:25:59,760 Speaker 1: firm warning, um, do not proceed, rethink what you were 455 00:25:59,760 --> 00:26:04,040 Speaker 1: doing is interpreted as a success. Yeah, exactly, though not 456 00:26:04,119 --> 00:26:07,160 Speaker 1: by everyone. I should note because the paper by chin 457 00:26:07,240 --> 00:26:09,840 Speaker 1: Ye and chin Ye notes that there was a rival 458 00:26:09,920 --> 00:26:14,399 Speaker 1: Parisian physician named Guillome Lamie who he disagreed, and he 459 00:26:14,520 --> 00:26:17,240 Speaker 1: argued that the black urine was a negative reaction to 460 00:26:17,280 --> 00:26:20,560 Speaker 1: the calf's blood. But the reason, he said was that 461 00:26:20,600 --> 00:26:23,439 Speaker 1: it was indicative of the body's attempt to purge the 462 00:26:23,480 --> 00:26:27,800 Speaker 1: contamination of a substance that was against its nature, which 463 00:26:28,240 --> 00:26:31,480 Speaker 1: sounds kind of close. But I think this opposition is 464 00:26:31,520 --> 00:26:34,520 Speaker 1: being infused with, you know, ideas of sort of like 465 00:26:34,800 --> 00:26:39,920 Speaker 1: spiritual essential is um that are not really proper in medicine. Uh. 466 00:26:40,119 --> 00:26:43,440 Speaker 1: It sounds to me like Mroy was probably suffering from 467 00:26:43,440 --> 00:26:47,480 Speaker 1: what is now called an acute hemolytic reaction, which is 468 00:26:47,840 --> 00:26:51,720 Speaker 1: a widely known rare side effect of a blood transfusion, 469 00:26:51,760 --> 00:26:53,800 Speaker 1: I guess, more common if it is not a properly 470 00:26:54,000 --> 00:26:58,240 Speaker 1: controlled blood transfusion, and this is where the recipient's immune 471 00:26:58,240 --> 00:27:03,560 Speaker 1: system interprets the donor red blood cells as invasive pathogens 472 00:27:03,600 --> 00:27:08,520 Speaker 1: and attacks them hemolysis in in the name acute hemolytic reaction. 473 00:27:08,600 --> 00:27:12,760 Speaker 1: Hemallysis means the destruction of red blood cells, and then 474 00:27:12,760 --> 00:27:16,000 Speaker 1: the red blood cells under attack release a substance into 475 00:27:16,000 --> 00:27:18,720 Speaker 1: the blood that the body has to try to purge, 476 00:27:18,760 --> 00:27:21,800 Speaker 1: and this substance can cause severe damage to the kidneys. 477 00:27:22,359 --> 00:27:25,560 Speaker 1: And this will sound pretty familiar now. Symptoms of an 478 00:27:25,600 --> 00:27:29,920 Speaker 1: acute hemolytic reaction include, among other things, chest and lower 479 00:27:29,960 --> 00:27:34,159 Speaker 1: back pain, nausea, and dark urine. But then there is 480 00:27:34,200 --> 00:27:37,879 Speaker 1: an even stranger epilogue to the Moroy story. Uh So, 481 00:27:38,000 --> 00:27:42,119 Speaker 1: picking up with what's covered in the Chandler at All paper, Denny, 482 00:27:42,200 --> 00:27:45,359 Speaker 1: of course considered Moroy somewhat cured, and I guess this 483 00:27:45,440 --> 00:27:48,520 Speaker 1: meant that he was no longer a seeker of sensual pleasures, 484 00:27:48,560 --> 00:27:51,640 Speaker 1: at least at first after what happened. And the authors 485 00:27:51,680 --> 00:27:54,880 Speaker 1: here say that at first Maroy behaved as his wife wished, 486 00:27:55,000 --> 00:27:58,239 Speaker 1: but then he became truculent again, and they say this 487 00:27:58,320 --> 00:28:01,480 Speaker 1: was quote prompting her to insist st on another transfusion. 488 00:28:01,920 --> 00:28:05,240 Speaker 1: Moroy refused to cooperate and received no blood, so he 489 00:28:05,320 --> 00:28:07,400 Speaker 1: was going to get a third transfusion, but it didn't 490 00:28:07,440 --> 00:28:10,919 Speaker 1: go forward, and then quote he died that evening, and 491 00:28:11,040 --> 00:28:14,840 Speaker 1: his wife perhaps with the encouragement of some physician critics, 492 00:28:14,880 --> 00:28:18,399 Speaker 1: accused Denny of killing her husband. Denny was tried for 493 00:28:18,560 --> 00:28:22,919 Speaker 1: manslaughter but exonerated when it was discovered that Mrs Moroy 494 00:28:23,119 --> 00:28:27,560 Speaker 1: was poisoning her husband with arsenic and then the following year, 495 00:28:27,640 --> 00:28:31,199 Speaker 1: the French Parliament enacted a ban on transfusion of blood 496 00:28:31,200 --> 00:28:34,840 Speaker 1: into humans, so he tries to do this third transfusion 497 00:28:35,520 --> 00:28:39,200 Speaker 1: doesn't work out. Maroy dies, his wife is found to 498 00:28:39,240 --> 00:28:41,400 Speaker 1: have been poisoning him, or at least is believed to 499 00:28:41,440 --> 00:28:43,360 Speaker 1: have been poisoning him, and then we get a ban 500 00:28:43,520 --> 00:28:47,360 Speaker 1: on on transfusions in France. But it also doesn't stop 501 00:28:47,440 --> 00:28:50,520 Speaker 1: there because while you can imagine it's common enough for 502 00:28:50,600 --> 00:28:53,200 Speaker 1: a person to be murdered by a spouse, the story 503 00:28:53,240 --> 00:28:56,080 Speaker 1: gets even more complicated. I was reading about a book 504 00:28:56,200 --> 00:29:01,160 Speaker 1: by a Vanderbilt University historian named Holly tuck Her that 505 00:29:01,600 --> 00:29:06,080 Speaker 1: argues the case for a conspiracy of rival physicians to 506 00:29:06,360 --> 00:29:12,320 Speaker 1: intentionally murder Antoine Mouroy and framed Deny fore causing his death. Now, 507 00:29:12,320 --> 00:29:15,840 Speaker 1: I haven't read this book. That sounds extremely interesting, but 508 00:29:15,920 --> 00:29:17,880 Speaker 1: I want to give you the gist, mostly based on 509 00:29:17,920 --> 00:29:22,000 Speaker 1: a review in the Journal of Clinical Investigation by Neil Blumberg. So, 510 00:29:22,160 --> 00:29:26,360 Speaker 1: to start, we know that Denise galenic humor theory was 511 00:29:26,400 --> 00:29:29,080 Speaker 1: hopelessly misguided. Right, This is not a good basis for 512 00:29:29,120 --> 00:29:32,320 Speaker 1: medical intervention. There is no reason to think that blood 513 00:29:32,400 --> 00:29:35,800 Speaker 1: from a docile lamb will treat mania and humans mental 514 00:29:35,840 --> 00:29:39,160 Speaker 1: illness doesn't work that way, and there's no way to 515 00:29:39,200 --> 00:29:41,600 Speaker 1: predict or prevent which of these would result in a 516 00:29:41,680 --> 00:29:45,280 Speaker 1: severe or life threatening rejection of the donor blood. But 517 00:29:45,560 --> 00:29:50,320 Speaker 1: despite how misguided and dangerous Denise treatments were, Denise rivals 518 00:29:50,400 --> 00:29:54,360 Speaker 1: opposed them for almost equally misguided reasons. A lot of 519 00:29:54,400 --> 00:29:59,120 Speaker 1: these I think some were probably just sort of motivated 520 00:29:59,120 --> 00:30:01,280 Speaker 1: by ambition, you know, they were kind of temporal and 521 00:30:01,360 --> 00:30:06,240 Speaker 1: political rivalries. But many of Denise opponents had extreme religious 522 00:30:06,280 --> 00:30:11,160 Speaker 1: and conceptual opposition to blood transfusions. For example, some of 523 00:30:11,200 --> 00:30:14,320 Speaker 1: them believed that the transfusion of blood from an animal 524 00:30:14,720 --> 00:30:18,040 Speaker 1: could turn a human into a type of chimera or 525 00:30:18,120 --> 00:30:21,280 Speaker 1: some kind of animal human hybrid. You might become a 526 00:30:21,360 --> 00:30:25,360 Speaker 1: subhuman ware lamb or a ware calf, which is very 527 00:30:25,360 --> 00:30:30,520 Speaker 1: Gary Larson uh. And some also believed that the ingestion 528 00:30:30,680 --> 00:30:35,320 Speaker 1: of foreign blood through transfusion was a slippery slope to cannibalism. 529 00:30:35,360 --> 00:30:37,520 Speaker 1: I'm not quite sure how you get there, but that 530 00:30:37,600 --> 00:30:40,360 Speaker 1: at least was was argued. Yeah, because it's I mean, 531 00:30:40,400 --> 00:30:43,560 Speaker 1: it's not like the humans we're talking about here weren't 532 00:30:43,560 --> 00:30:47,880 Speaker 1: already eating meat, right, Yeah, I would think that the 533 00:30:47,920 --> 00:30:51,000 Speaker 1: eating of meat would more likely give way to cannibalism 534 00:30:51,040 --> 00:30:54,680 Speaker 1: than the transfusion of blood from animals. Yeah. Yeah, And 535 00:30:54,760 --> 00:30:57,080 Speaker 1: this might sound kind of outlandish, like, well, how could 536 00:30:57,080 --> 00:30:58,920 Speaker 1: you get to that, you know, how could you have 537 00:30:59,040 --> 00:31:02,440 Speaker 1: this kind of opposite sh into blood transfusions? But uh, 538 00:31:02,600 --> 00:31:05,040 Speaker 1: I know, the case is made in Holly Tucker's book, 539 00:31:05,040 --> 00:31:07,760 Speaker 1: and Bloomberg himself brings up as a point of comparison 540 00:31:08,160 --> 00:31:11,520 Speaker 1: that quote. One might consider that current disagreements about stem 541 00:31:11,600 --> 00:31:14,960 Speaker 1: cell therapies are similar in nature, as some find it 542 00:31:15,000 --> 00:31:19,760 Speaker 1: impossible to separate considerations of religious belief and scientific approach. 543 00:31:20,360 --> 00:31:24,440 Speaker 1: So even today, we certainly do have, you know, bioethical 544 00:31:24,480 --> 00:31:29,120 Speaker 1: debates that are largely prompted by religious beliefs. That's true, 545 00:31:29,280 --> 00:31:31,680 Speaker 1: that's true. I mean, you know, I certainly think to 546 00:31:31,760 --> 00:31:37,520 Speaker 1: any number of of chimerical um uh studies that have 547 00:31:37,600 --> 00:31:40,040 Speaker 1: come out, you know, there's always going to be that 548 00:31:40,040 --> 00:31:42,400 Speaker 1: that voice of criticism. That's going to raise the specter 549 00:31:42,520 --> 00:31:45,480 Speaker 1: of some sort of uh, you know, man goat hybrid 550 00:31:45,600 --> 00:31:48,080 Speaker 1: or whatever the case may be. Right, this is against nature, 551 00:31:48,240 --> 00:31:52,400 Speaker 1: This is a perversion. Yeah, yeah, the shadow of Frankenstein there. 552 00:31:52,960 --> 00:31:55,080 Speaker 1: At the same time, it's interesting looking at all this 553 00:31:55,160 --> 00:31:57,680 Speaker 1: and thinking about like the sort of spirit that the 554 00:31:57,720 --> 00:31:59,960 Speaker 1: spiritual and religious ideas that are kind of a tribute 555 00:32:00,040 --> 00:32:03,120 Speaker 1: it to the idea of of first and foremost, you know, 556 00:32:03,160 --> 00:32:05,640 Speaker 1: the draining of the blood, the bleeding of the patient, 557 00:32:05,880 --> 00:32:08,200 Speaker 1: but then the idea of well it looks like, uh, 558 00:32:08,720 --> 00:32:11,840 Speaker 1: looks like your treatment didn't take You're still running, trying 559 00:32:11,840 --> 00:32:13,600 Speaker 1: to run off to Paris. We need to replace that 560 00:32:13,600 --> 00:32:16,800 Speaker 1: blood again. It reminds me of some of the criticisms 561 00:32:16,880 --> 00:32:21,080 Speaker 1: leveled at so called young blood transfusion that we've uh 562 00:32:21,200 --> 00:32:23,920 Speaker 1: we we've seen in in in recent years. You know, 563 00:32:23,960 --> 00:32:27,240 Speaker 1: the idea that an an older person could receive the 564 00:32:27,280 --> 00:32:30,720 Speaker 1: transfused blood of a younger person, uh, with some sort 565 00:32:30,760 --> 00:32:32,800 Speaker 1: of health benefits. And I believe this is this is 566 00:32:33,120 --> 00:32:37,280 Speaker 1: largely seen as pseudo scientific um. But but but I 567 00:32:37,280 --> 00:32:39,520 Speaker 1: can I can see some of the same energy in 568 00:32:40,000 --> 00:32:43,160 Speaker 1: young blood transfusion that you see kind of attributed to 569 00:32:43,920 --> 00:32:47,000 Speaker 1: the the you know, the poorly understood nature of blood 570 00:32:47,000 --> 00:32:50,800 Speaker 1: transfusion at the time in the UH the seventeenth century. Yeah, 571 00:32:50,840 --> 00:32:53,280 Speaker 1: I can totally see that, like this view of there's 572 00:32:53,320 --> 00:32:57,440 Speaker 1: some kind of unholy experiment that's being done in in 573 00:32:57,560 --> 00:33:01,200 Speaker 1: dark rooms that we don't have access to. And by 574 00:33:01,240 --> 00:33:04,480 Speaker 1: the way, anyone who watched the television series Silicon Valley 575 00:33:04,520 --> 00:33:08,240 Speaker 1: you might remember the the the young blood UH thing 576 00:33:08,320 --> 00:33:11,000 Speaker 1: being a part of the plot as the Holy Founder. A. 577 00:33:11,040 --> 00:33:13,760 Speaker 1: Gavin Belson at one point has a quote unquote blood 578 00:33:13,760 --> 00:33:17,480 Speaker 1: boy who was responsible for providing him blood transfusions to 579 00:33:17,720 --> 00:33:20,320 Speaker 1: UH as as a as a believe like a life 580 00:33:20,320 --> 00:33:23,520 Speaker 1: hack to keep him young. Home man. Well, it's interesting 581 00:33:23,560 --> 00:33:26,920 Speaker 1: again to compare to the case of Dennis and his rivals. 582 00:33:27,560 --> 00:33:29,720 Speaker 1: I mean, well, maybe I should finish it first and 583 00:33:29,720 --> 00:33:32,600 Speaker 1: then say this. So. In the end, Holly Tucker's book 584 00:33:32,960 --> 00:33:37,200 Speaker 1: makes the argument that it was denise opponents, especially a 585 00:33:37,200 --> 00:33:41,840 Speaker 1: physician named Henri Martin de la Martiniere, who arranged the 586 00:33:41,960 --> 00:33:46,080 Speaker 1: murder of the patient of Antoine Mouroy by giving arsenic 587 00:33:46,080 --> 00:33:50,000 Speaker 1: to Moroy's wife and encouraging her to poison him. Ultimately, 588 00:33:50,200 --> 00:33:53,640 Speaker 1: she argues this was in an attempt to discredit Denise 589 00:33:53,760 --> 00:33:57,200 Speaker 1: medical theories, and it's a it's a case where there's 590 00:33:57,200 --> 00:34:00,520 Speaker 1: really no good guys because if you know, if Holly 591 00:34:00,560 --> 00:34:03,280 Speaker 1: Tucker's theory is correct, and they really did this, it 592 00:34:03,360 --> 00:34:06,880 Speaker 1: was a case of two camps that were both entirely 593 00:34:07,000 --> 00:34:12,600 Speaker 1: wrong fighting over this conceptual biomedical space. Oh wow, this 594 00:34:12,920 --> 00:34:15,640 Speaker 1: is such a wonderful bit of a bit of history. It. 595 00:34:16,520 --> 00:34:19,000 Speaker 1: I wonder if this has been adapted in any kind 596 00:34:19,040 --> 00:34:22,040 Speaker 1: of historical drama, because it's perfect for that sort of thing. Yeah, 597 00:34:22,080 --> 00:34:26,040 Speaker 1: absolutely so. Anyway, that that is the very weird story 598 00:34:26,080 --> 00:34:30,640 Speaker 1: of early zeno transfusion in sixteen sixties France. Now, xeno 599 00:34:30,680 --> 00:34:35,640 Speaker 1: transfusion is technically still on the table today, but it's 600 00:34:35,640 --> 00:34:39,280 Speaker 1: generally not practiced with humans today because generally human blood 601 00:34:39,520 --> 00:34:44,640 Speaker 1: is much more forthcoming. Um but uh, but yeah, this 602 00:34:44,800 --> 00:34:47,759 Speaker 1: this strange history of of of blood, not just as 603 00:34:47,840 --> 00:34:49,880 Speaker 1: zeno transfusion, but again, thinking of the idea of like 604 00:34:49,960 --> 00:34:54,000 Speaker 1: beer and urine or or milk being used. Uh, this 605 00:34:54,080 --> 00:34:57,480 Speaker 1: brings to mind the various alternative bloods you often encounter 606 00:34:57,600 --> 00:35:00,480 Speaker 1: in humanoid beings in sci fi and fantasy. You know, 607 00:35:00,520 --> 00:35:03,320 Speaker 1: I instantly think of the milk white blood in Ridley 608 00:35:03,360 --> 00:35:07,400 Speaker 1: Scott's various androids or the yellow blood that you see 609 00:35:07,440 --> 00:35:10,920 Speaker 1: in Phantasms the Tall Man, or in the The Androids 610 00:35:10,960 --> 00:35:15,120 Speaker 1: of Halloween three, one of my favorites. Yeah. Um. Now, 611 00:35:15,360 --> 00:35:18,960 Speaker 1: on the subject of milk, Sarkar rights that indeed, in 612 00:35:19,040 --> 00:35:22,239 Speaker 1: eighteen fifty four, milk was injected into the veins of 613 00:35:22,320 --> 00:35:25,799 Speaker 1: patients with the asiatic cholera, thinking that it would help 614 00:35:25,840 --> 00:35:29,360 Speaker 1: regenerate white blood. Sells, Oh, maybe is it like a 615 00:35:29,400 --> 00:35:33,719 Speaker 1: color match thing. That's what it sounds like. Now. The 616 00:35:33,719 --> 00:35:37,239 Speaker 1: thing is enough patients survived that they kept trying it. 617 00:35:38,120 --> 00:35:40,640 Speaker 1: They're like, well, nobody's dying. It seems like they're eventually 618 00:35:40,640 --> 00:35:43,360 Speaker 1: getting better. Let's just keep doing it. And there's a 619 00:35:43,360 --> 00:35:46,760 Speaker 1: lot of skepticism about the practice even at that time, 620 00:35:47,080 --> 00:35:50,120 Speaker 1: and this never really took off. There is so much 621 00:35:50,160 --> 00:35:53,279 Speaker 1: of medical history in a way, it's almost it's amazing 622 00:35:53,400 --> 00:35:56,640 Speaker 1: that medicine exists at all, because I don't know what 623 00:35:56,760 --> 00:36:00,120 Speaker 1: the year was, where on the whole medicine became more 624 00:36:00,160 --> 00:36:04,640 Speaker 1: helpful than harmful. It's like shockingly recent. If you go 625 00:36:05,600 --> 00:36:07,920 Speaker 1: not even all that far back into the past, it 626 00:36:07,960 --> 00:36:11,920 Speaker 1: seems like the majority of medical interventions were just like 627 00:36:12,120 --> 00:36:14,919 Speaker 1: painful and terrible and did nothing to help and maybe 628 00:36:14,920 --> 00:36:17,600 Speaker 1: it would kill you. Yeah. Once again, I come back 629 00:36:17,640 --> 00:36:21,560 Speaker 1: to that that that excellent Soderberg television series The Nick, 630 00:36:22,000 --> 00:36:24,400 Speaker 1: which takes place in New York City and nine D 631 00:36:24,920 --> 00:36:28,040 Speaker 1: and it's just portraying just the cutting edge of medicine 632 00:36:28,040 --> 00:36:30,560 Speaker 1: at the time, and even you know then you see 633 00:36:30,600 --> 00:36:34,160 Speaker 1: like just the catastrophic ways they get it wrong at times. Uh, 634 00:36:34,200 --> 00:36:37,280 Speaker 1: you know, be at things like blood transfusions or drug 635 00:36:37,320 --> 00:36:40,359 Speaker 1: interactions or the use of X rays. Now, in terms 636 00:36:40,400 --> 00:36:43,279 Speaker 1: of other potential blood substitutes, things you can put into 637 00:36:43,320 --> 00:36:45,920 Speaker 1: the body in place of at least some of the blood, uh, 638 00:36:45,960 --> 00:36:49,440 Speaker 1: sailing solutions seemed to promising, uh solution for a bit 639 00:36:49,560 --> 00:36:52,320 Speaker 1: fair as doctors found that you could give a frog 640 00:36:52,480 --> 00:36:56,239 Speaker 1: a complete transfusion of sailing and it would survive, though 641 00:36:56,280 --> 00:36:59,319 Speaker 1: only for a short while. Um. However, that this is 642 00:36:59,320 --> 00:37:03,400 Speaker 1: the stuff was stally developed as a plasma volume expander. Now, 643 00:37:03,440 --> 00:37:05,719 Speaker 1: Sarkar does not go into detail about the beer and 644 00:37:05,800 --> 00:37:09,399 Speaker 1: the urine um tidbits, but they certainly don't highlight them 645 00:37:09,400 --> 00:37:14,480 Speaker 1: as successes. So UM, I assume they were not, you know, 646 00:37:14,600 --> 00:37:18,279 Speaker 1: huge medical successes. Now, in the eighteen hundreds, hemoglobin and 647 00:37:18,320 --> 00:37:21,920 Speaker 1: animal plasma seemed promising, but there were technical hurdles to 648 00:37:22,120 --> 00:37:27,160 Speaker 1: isolating enough hemoglobin, and animal blood um often contain toxins 649 00:37:27,200 --> 00:37:30,320 Speaker 1: that we're challenging to remove at the time. In eighteen 650 00:37:30,400 --> 00:37:33,880 Speaker 1: eighty three, the creation of Ringer's solution. This is named 651 00:37:34,000 --> 00:37:38,640 Speaker 1: for Sydney Ringer, who lived eighteen nine. UH. This changed 652 00:37:38,680 --> 00:37:41,280 Speaker 1: things a bit. Uh. So this is a solution of sodium, 653 00:37:41,280 --> 00:37:44,840 Speaker 1: potassium and calcium salts that was found to restore healthy 654 00:37:44,840 --> 00:37:48,239 Speaker 1: blood pressure after blood volume loss, and it's still used 655 00:37:48,239 --> 00:37:50,759 Speaker 1: today as a blood volume expander, but it does not 656 00:37:50,920 --> 00:37:54,040 Speaker 1: actually work as a blood substitute. Again, we have to 657 00:37:54,080 --> 00:37:57,560 Speaker 1: think of all the things that that blood does, and 658 00:37:57,760 --> 00:38:01,279 Speaker 1: this particular solution it doesn't, for instance, do anything that 659 00:38:01,320 --> 00:38:04,959 Speaker 1: red blood cells do, such as carrying oxygen. Because again, 660 00:38:04,960 --> 00:38:07,000 Speaker 1: the human body is not just a big blood balloon. 661 00:38:07,080 --> 00:38:09,399 Speaker 1: You know, It's not just about warm volume. It's about 662 00:38:09,440 --> 00:38:11,920 Speaker 1: the vital function of the blood. So you can boost 663 00:38:11,920 --> 00:38:15,040 Speaker 1: the volume, but you still need something in the veins 664 00:38:15,120 --> 00:38:18,080 Speaker 1: doing the things that blood does. Now, as we discussed 665 00:38:18,120 --> 00:38:21,360 Speaker 1: in our previous episode on blood types, UH, the Austrian 666 00:38:21,640 --> 00:38:26,000 Speaker 1: UH immunologists and pathologist Carl Landsteiner, who of eighteen sixty 667 00:38:26,040 --> 00:38:29,720 Speaker 1: eight through ninety three discovered the primary a bio blood 668 00:38:29,719 --> 00:38:33,560 Speaker 1: groups around the years nineteen hundred or nineteen o one. 669 00:38:34,040 --> 00:38:37,240 Speaker 1: At the time, doctors knew that many blood transfusions caused 670 00:38:37,280 --> 00:38:41,400 Speaker 1: adverse reactions in their recipient, mainly agglutination, which is where 671 00:38:41,280 --> 00:38:45,600 Speaker 1: the red blood cells clumped together. Blood transfusion technology advanced 672 00:38:45,600 --> 00:38:48,479 Speaker 1: a great deal from from that point on, and um 673 00:38:48,560 --> 00:38:51,680 Speaker 1: an interest in blood substitute was renewed, especially during the 674 00:38:51,680 --> 00:38:54,040 Speaker 1: World Wars of the twentieth century. I think I said 675 00:38:54,080 --> 00:38:56,080 Speaker 1: this in the Last Blood episode, but I can't see 676 00:38:56,080 --> 00:38:58,640 Speaker 1: the name of Carl Landsteiner without thinking of him as 677 00:38:58,960 --> 00:39:04,959 Speaker 1: Carl landst Er. Alright, So fast forward to nineteen sixty six. 678 00:39:05,120 --> 00:39:08,960 Speaker 1: This is when um per floro chemicals or PFC was 679 00:39:09,040 --> 00:39:12,040 Speaker 1: explored as a potential blood substitute. Doctors found that a 680 00:39:12,200 --> 00:39:15,680 Speaker 1: rat's blood could be completely removed and replaced with the stuff, 681 00:39:15,680 --> 00:39:18,080 Speaker 1: but only for a few hours at a time. Uh. 682 00:39:18,120 --> 00:39:20,720 Speaker 1: This stuff then had to be replaced with actual blood, 683 00:39:20,760 --> 00:39:24,399 Speaker 1: but a full recovery was possible. So obviously you can 684 00:39:24,400 --> 00:39:27,720 Speaker 1: see the possibilities there. You know, something something that's not blood. 685 00:39:27,760 --> 00:39:29,200 Speaker 1: We could at least get in there for a little 686 00:39:29,200 --> 00:39:32,239 Speaker 1: bit to stabilize the patient until actual blood can be 687 00:39:32,280 --> 00:39:35,640 Speaker 1: made available. Star Car writes that while there was renewed 688 00:39:35,680 --> 00:39:39,160 Speaker 1: interest during the AIDS epidemic and during Vietnam, for the 689 00:39:39,239 --> 00:39:43,520 Speaker 1: most part, advances in blood banking itself has, you know, 690 00:39:43,640 --> 00:39:46,799 Speaker 1: has resulted in less research for the idea of a 691 00:39:46,840 --> 00:39:50,799 Speaker 1: true blood substitute, because ultimately, nothing takes the place of 692 00:39:50,920 --> 00:39:53,839 Speaker 1: human blood quite like human blood. But if we're going 693 00:39:53,880 --> 00:39:57,000 Speaker 1: to have synthetic blood, star Car points out that there 694 00:39:57,040 --> 00:40:01,760 Speaker 1: are a few key uh points that must be met. Okay, 695 00:40:01,800 --> 00:40:03,719 Speaker 1: like what so, First of all, it has to be 696 00:40:03,800 --> 00:40:07,560 Speaker 1: safe and compatible with the human body. Ideally, it should 697 00:40:07,560 --> 00:40:10,520 Speaker 1: also be universal for all blood types. You know, that's 698 00:40:10,560 --> 00:40:13,520 Speaker 1: not an absolute requirement, but certainly, if you're talking about 699 00:40:13,560 --> 00:40:15,960 Speaker 1: something that is just on a hand, say in a 700 00:40:16,040 --> 00:40:20,239 Speaker 1: field hospital situation, to hold the patient over until an 701 00:40:20,239 --> 00:40:23,279 Speaker 1: actual blood bank can come into play, it would be 702 00:40:23,360 --> 00:40:25,440 Speaker 1: nice if it just took care of all humans and 703 00:40:25,480 --> 00:40:28,520 Speaker 1: you didn't have to to deal with type. On top 704 00:40:28,520 --> 00:40:30,600 Speaker 1: of that, it needs to be able to transport oxygen 705 00:40:30,640 --> 00:40:34,160 Speaker 1: throughout the body, and it needs to offer more robust 706 00:40:34,239 --> 00:40:37,400 Speaker 1: shelf stability, such as lasting a year rather than a 707 00:40:37,440 --> 00:40:40,920 Speaker 1: mere month as with donor blood. As such, there are 708 00:40:41,120 --> 00:40:44,560 Speaker 1: basically two major areas of research under way. First of all, 709 00:40:44,719 --> 00:40:48,440 Speaker 1: per floral carbons, these are inexpensive, they're devoid of biological 710 00:40:48,480 --> 00:40:51,920 Speaker 1: materials that could spread infection. However, they're not water soluble 711 00:40:52,160 --> 00:40:57,160 Speaker 1: and they carry much less oxygen compared to hemoglobin based products. Second, 712 00:40:57,239 --> 00:41:00,840 Speaker 1: you have hemoglobin based products, so these are oxygen containing. 713 00:41:00,880 --> 00:41:04,560 Speaker 1: They're involved in oxygen transport with our own red blood cells, 714 00:41:04,600 --> 00:41:07,360 Speaker 1: so it's a great place to start. Now. The downside 715 00:41:07,360 --> 00:41:10,680 Speaker 1: to this direction is that raw hemoglobin would break down 716 00:41:10,680 --> 00:41:15,239 Speaker 1: into toxic compounds, and there are solutions stability issues as well. 717 00:41:15,640 --> 00:41:19,720 Speaker 1: Quote the challenge and creating a hemoglobin based artificial blood 718 00:41:19,960 --> 00:41:23,960 Speaker 1: is to modify the hemoglobin molecule so these problems are resolved. 719 00:41:24,600 --> 00:41:29,160 Speaker 1: So you could depend on either isolated hemoglobin or synthetically 720 00:41:29,239 --> 00:41:34,040 Speaker 1: produced hemoglobin. If it's isolated, the product is actually made 721 00:41:34,080 --> 00:41:38,279 Speaker 1: from human blood, typically blood for transfusions that has already expired. 722 00:41:38,600 --> 00:41:41,360 Speaker 1: Animal blood is another option, apparently, but in this case 723 00:41:41,400 --> 00:41:47,200 Speaker 1: the hemoglobin would need to be modified before use. Hemoglobin synthesis, however, 724 00:41:47,320 --> 00:41:49,440 Speaker 1: is a process that involves the use of a strain 725 00:41:49,520 --> 00:41:52,640 Speaker 1: of E. Coli bacteria that has the ability to produce 726 00:41:52,760 --> 00:41:57,960 Speaker 1: human hemoglobin. There's a process involving bacterial destruction, fermentation and 727 00:41:58,040 --> 00:42:02,160 Speaker 1: isolation in a centrifuge, then final processing via the addition 728 00:42:02,200 --> 00:42:05,880 Speaker 1: of water and electrolytes, so farming it from bacteria. I 729 00:42:05,960 --> 00:42:10,040 Speaker 1: like that. Yeah. Yeah. Now, as as for limitations, again, 730 00:42:10,080 --> 00:42:13,080 Speaker 1: as of this paper's writing, most of the hemoglobin based 731 00:42:13,080 --> 00:42:15,840 Speaker 1: products were lasting no more than twenty to thirty hours 732 00:42:15,840 --> 00:42:19,480 Speaker 1: in the body hold. Blood transfusions last thirty four days 733 00:42:20,120 --> 00:42:23,560 Speaker 1: for comparison. Also, this sort of blood substitute wouldn't bring 734 00:42:23,600 --> 00:42:26,560 Speaker 1: clotting or disease fighting to the table, so that leaves 735 00:42:26,560 --> 00:42:29,760 Speaker 1: its potential again more as a short term solution, something 736 00:42:29,800 --> 00:42:32,719 Speaker 1: to get in the body, uh, while you're waiting to 737 00:42:32,800 --> 00:42:36,120 Speaker 1: access the fruits of blood bank. And of course this 738 00:42:36,160 --> 00:42:38,480 Speaker 1: is not even getting into some of the issues concerning 739 00:42:38,480 --> 00:42:44,840 Speaker 1: biosecurity and privatization of synthetic biology as it concerns ethical dimensions, etcetera. 740 00:42:45,200 --> 00:42:47,920 Speaker 1: Oh wait, so you could have like, uh, somebody's got 741 00:42:47,960 --> 00:42:51,000 Speaker 1: a patent on the blood that's in your arteries right now, 742 00:42:51,120 --> 00:42:53,120 Speaker 1: and yeah, well that's the well, that's the kind of 743 00:42:53,120 --> 00:42:57,680 Speaker 1: thing that's often brought up in these discussions. I mean, however, obviously, 744 00:42:57,680 --> 00:42:59,560 Speaker 1: the way I do, I do think it is important to, 745 00:42:59,680 --> 00:43:01,680 Speaker 1: you know, stress that it would be great if there 746 00:43:01,880 --> 00:43:05,680 Speaker 1: was if we were to develop a pure, you know, 747 00:43:05,719 --> 00:43:08,000 Speaker 1: blood substitute that, even if it only worked for a 748 00:43:08,000 --> 00:43:11,959 Speaker 1: short time, could be kept on hand. You know, that's 749 00:43:12,000 --> 00:43:15,480 Speaker 1: something that that was universal, something with with a decent 750 00:43:15,520 --> 00:43:18,200 Speaker 1: shelf life. Uh, you know, even if it wasn't a 751 00:43:18,200 --> 00:43:20,800 Speaker 1: permanent solution, if it wasn't quite as good as human blood, 752 00:43:21,000 --> 00:43:24,120 Speaker 1: if it could just serve as a as as a patch, 753 00:43:24,480 --> 00:43:27,360 Speaker 1: you know, until a proper blood transfusion can take place, 754 00:43:27,440 --> 00:43:30,440 Speaker 1: that would be immensely helpful. Totally. Should we take a 755 00:43:30,440 --> 00:43:32,960 Speaker 1: break and then come back to talk a little more, Yes, 756 00:43:34,360 --> 00:43:39,799 Speaker 1: thank alright, we're back. So I was looking around for 757 00:43:39,800 --> 00:43:42,040 Speaker 1: for more recent work. I was looking at a two 758 00:43:42,080 --> 00:43:45,440 Speaker 1: thousand seventeen study by Wing at All published in Bio 759 00:43:45,480 --> 00:43:49,480 Speaker 1: macro Molecules, and they point out that hemoglobin on its own, 760 00:43:49,520 --> 00:43:52,920 Speaker 1: like we discussed this toxic, but that a chemically modified 761 00:43:53,040 --> 00:43:58,000 Speaker 1: version forms um methemoglobin, which doesn't bind oxygen. Uh, this 762 00:43:58,520 --> 00:44:01,600 Speaker 1: decreases the oxygen in the blood. In the generation of 763 00:44:01,920 --> 00:44:06,759 Speaker 1: methemoglobin produces cell damaging hydrogen peroxide. So the researchers in 764 00:44:06,800 --> 00:44:10,440 Speaker 1: this case looked into packaging hemoglobin in a quote unquote 765 00:44:10,440 --> 00:44:15,360 Speaker 1: benign envelope in this case um polydopamine or p d A, 766 00:44:15,719 --> 00:44:20,160 Speaker 1: which is already understudy for biomedical applications. Their findings showed 767 00:44:20,239 --> 00:44:24,920 Speaker 1: promise with the package delivering oxygen while preventing the formation 768 00:44:25,400 --> 00:44:29,440 Speaker 1: of meth, methmoglobin and hydrogen peroxide, and this resulted in 769 00:44:29,480 --> 00:44:32,160 Speaker 1: minimal cell damage. I mean, you can see pretty easily 770 00:44:32,160 --> 00:44:34,680 Speaker 1: why you wouldn't really want too much hydrogen peroxide in 771 00:44:34,719 --> 00:44:39,640 Speaker 1: your blood right now on the xeno transfusion front. Uh, 772 00:44:39,800 --> 00:44:42,920 Speaker 1: this was interesting. I came across a case report in 773 00:44:42,960 --> 00:44:46,960 Speaker 1: Clinical Case Reports by Rubinstein at All which discusses the 774 00:44:46,960 --> 00:44:50,160 Speaker 1: case of a fifty seven year old Jehovah's Witness with 775 00:44:50,280 --> 00:44:54,840 Speaker 1: a form of pure red cell um aplasia or pr 776 00:44:54,920 --> 00:44:56,960 Speaker 1: c A. Now, this is a type of anemia that 777 00:44:57,040 --> 00:45:00,400 Speaker 1: impacts the patient's ability to produce red but not white 778 00:45:00,400 --> 00:45:04,400 Speaker 1: blood cells. So blood transfusions are an important form of treatment. 779 00:45:04,760 --> 00:45:08,160 Speaker 1: But the individual in question turned down these transfusions for 780 00:45:08,280 --> 00:45:12,600 Speaker 1: religious reasons. And I believe the stems with the Jehovah's 781 00:45:12,640 --> 00:45:16,839 Speaker 1: Witness faith is an interpretation of abstaining from blood in 782 00:45:16,880 --> 00:45:19,560 Speaker 1: the Bible. I think this is from Leviticus. Yeah, there 783 00:45:19,600 --> 00:45:23,000 Speaker 1: are multiple passages cited by the Jehovah's witnesses. I think 784 00:45:23,040 --> 00:45:25,920 Speaker 1: the most common one is this one in Leviticus chapter seventeen, 785 00:45:26,080 --> 00:45:29,000 Speaker 1: where it says, Uh, for the life of the flesh 786 00:45:29,080 --> 00:45:30,799 Speaker 1: is in the blood, and I have given it to 787 00:45:30,800 --> 00:45:33,240 Speaker 1: you upon the altar to make atonement for your souls. 788 00:45:33,320 --> 00:45:35,759 Speaker 1: For it is the blood that makes the atonement for 789 00:45:35,760 --> 00:45:38,640 Speaker 1: the soul. Uh. And he says, therefore, to the children 790 00:45:38,640 --> 00:45:41,640 Speaker 1: of Israel, you shall not eat blood. And this and 791 00:45:41,840 --> 00:45:45,040 Speaker 1: some other passages are sort of interpreted in a in 792 00:45:45,080 --> 00:45:47,160 Speaker 1: a way to say, well, to be safe in following this, 793 00:45:47,280 --> 00:45:50,680 Speaker 1: you probably shouldn't receive blood transfusions either. But I was 794 00:45:50,680 --> 00:45:54,160 Speaker 1: actually this is this is interesting. There's a whole Wikipedia 795 00:45:54,200 --> 00:45:58,600 Speaker 1: page on the Jehovah's Witnesses and blood transfusions that has 796 00:45:58,640 --> 00:46:04,160 Speaker 1: this gigantic of what types of procedures are allowed and 797 00:46:04,200 --> 00:46:07,120 Speaker 1: what are not allowed according to Church doctrine, because there 798 00:46:07,160 --> 00:46:10,200 Speaker 1: are there's not just one type of blood transfusion. They 799 00:46:10,239 --> 00:46:13,960 Speaker 1: are all kinds of blood related products that you can 800 00:46:14,120 --> 00:46:16,239 Speaker 1: have put into your body, and so there are some 801 00:46:16,360 --> 00:46:19,320 Speaker 1: that they accept and some they don't. In this case, however, 802 00:46:19,400 --> 00:46:21,120 Speaker 1: it seems like it was it was pretty much. A 803 00:46:21,200 --> 00:46:24,560 Speaker 1: don't on the idea of more human blood being put 804 00:46:24,600 --> 00:46:29,000 Speaker 1: into the patient for this treatment, but in this case, 805 00:46:29,160 --> 00:46:35,440 Speaker 1: the physicians used a quote bovine hemoglobin based oxygen carrier quote. 806 00:46:35,480 --> 00:46:39,200 Speaker 1: The patient received more than twenty units of HBOC two 807 00:46:39,200 --> 00:46:42,040 Speaker 1: oh one and was showing early signs of red blood 808 00:46:42,040 --> 00:46:45,800 Speaker 1: cell count recovery. Although the patient did not survive, administration 809 00:46:45,880 --> 00:46:48,920 Speaker 1: of the HBOC two o one did sustain her long 810 00:46:49,040 --> 00:46:53,880 Speaker 1: enough to allow for administration of immunosuppressive therapy, which ultimately 811 00:46:54,239 --> 00:47:01,520 Speaker 1: improved erythropoesis. Thus, administration of alternative hemoglobin based oxygen carriers 812 00:47:01,560 --> 00:47:04,719 Speaker 1: in the setting of red cell at plasia associated with 813 00:47:04,920 --> 00:47:08,920 Speaker 1: thy momus warrants further investigation. And that's interesting. So this 814 00:47:08,960 --> 00:47:13,560 Speaker 1: is a product that is derived from the hemoglobin, the 815 00:47:13,680 --> 00:47:16,279 Speaker 1: oxygen carrying protein that would be found in the red 816 00:47:16,280 --> 00:47:19,080 Speaker 1: blood cells originally of cows or some of their bovine 817 00:47:19,640 --> 00:47:21,839 Speaker 1: And uh yeah, And I think this is in line 818 00:47:21,840 --> 00:47:23,279 Speaker 1: with a lot of the stuff I was seeing about 819 00:47:23,320 --> 00:47:27,240 Speaker 1: Jehovah's witnesses beliefs that um often that they will receive 820 00:47:27,320 --> 00:47:30,000 Speaker 1: certain types of blood products, but the objection more often 821 00:47:30,120 --> 00:47:33,880 Speaker 1: is to whole blood. Now, leaving medical research and uh, 822 00:47:33,920 --> 00:47:36,960 Speaker 1: and religious beliefs. Maybe we should come back to our 823 00:47:37,040 --> 00:47:43,240 Speaker 1: vampire introduction because I think you were hypothesizing that vampires 824 00:47:43,400 --> 00:47:46,839 Speaker 1: might might find themselves rather picky over what types of 825 00:47:46,880 --> 00:47:50,000 Speaker 1: synthetic blood are are tasty or or go well with 826 00:47:50,080 --> 00:47:51,600 Speaker 1: their I don't know what it would it be the 827 00:47:51,600 --> 00:47:56,400 Speaker 1: digestive system, what system receives the blood vampire? Well, I 828 00:47:56,400 --> 00:47:59,399 Speaker 1: guess that's the tricky thing about vampires, right, is that there, 829 00:47:59,440 --> 00:48:02,200 Speaker 1: of course create is a fantasy and interpretations of their 830 00:48:02,280 --> 00:48:05,360 Speaker 1: their blood drinking. It's going to range from the biological, 831 00:48:06,239 --> 00:48:10,080 Speaker 1: the biologically grounded, to the utterly magical. So what like, 832 00:48:10,160 --> 00:48:12,080 Speaker 1: what is the nature of the blood that the vampire 833 00:48:12,160 --> 00:48:15,280 Speaker 1: is drinking? Are they drinking like the magical life force 834 00:48:15,360 --> 00:48:18,360 Speaker 1: of a being, you know, the splendid iy core of 835 00:48:19,040 --> 00:48:21,840 Speaker 1: the Sons of Adam? Or is it like actual blood? 836 00:48:21,880 --> 00:48:25,920 Speaker 1: Are they an actual sangovore much like a vampire bat? 837 00:48:26,400 --> 00:48:28,279 Speaker 1: And obviously, depending on what your answer is is going 838 00:48:28,320 --> 00:48:30,799 Speaker 1: to be, you know, entirely different, and certainly you could 839 00:48:30,840 --> 00:48:33,319 Speaker 1: have You can imagine a situation where you have a 840 00:48:33,360 --> 00:48:38,439 Speaker 1: synthetic blood that is certainly helpful treating individuals who who 841 00:48:38,480 --> 00:48:40,719 Speaker 1: who need it, but is going to be kind of 842 00:48:40,840 --> 00:48:44,120 Speaker 1: useless or at least not all that desired by blood 843 00:48:44,200 --> 00:48:48,759 Speaker 1: drinking supernatural beings. But I thought, you know, what's what's 844 00:48:48,760 --> 00:48:51,440 Speaker 1: the one thing we can definitely do. We can definitely 845 00:48:51,480 --> 00:48:54,560 Speaker 1: look to the vampire bats. We can look at blood 846 00:48:54,640 --> 00:48:57,160 Speaker 1: drinking in the natural world and see if there's anything 847 00:48:57,200 --> 00:49:00,239 Speaker 1: out there that at all relates to this question. So 848 00:49:00,280 --> 00:49:03,319 Speaker 1: I was looking at wanted blood for vampire bats by 849 00:49:03,400 --> 00:49:07,319 Speaker 1: Lynn Laws, writing for the Iowa State University College of 850 00:49:07,360 --> 00:49:12,239 Speaker 1: Agricultural and Life Sciences. So, vampire bats we've discussed in 851 00:49:12,280 --> 00:49:15,920 Speaker 1: the show before typically feed on fresh cow blood and 852 00:49:16,040 --> 00:49:21,400 Speaker 1: only rarely bite humans. Typically for captive vampire bats, and 853 00:49:21,600 --> 00:49:24,200 Speaker 1: like a laboratory or a zoo environment or some sort 854 00:49:24,239 --> 00:49:28,200 Speaker 1: of enclosure, cow blood does the trick um, but in 855 00:49:28,280 --> 00:49:32,600 Speaker 1: zoo conditions, especially, an anticoagulant is added to the blood 856 00:49:32,600 --> 00:49:35,800 Speaker 1: to keep it fresh enough for feeding via little peachy 857 00:49:35,920 --> 00:49:38,919 Speaker 1: dishes that are placed out in the enclosure. Oh I see, 858 00:49:38,960 --> 00:49:41,520 Speaker 1: So like, if you don't add an anticoagulant, you could 859 00:49:41,520 --> 00:49:43,160 Speaker 1: have the same problem you get where you leave the 860 00:49:43,239 --> 00:49:46,879 Speaker 1: soup out and it forms a skin. Yeah, one imagines, yeah, 861 00:49:46,920 --> 00:49:50,120 Speaker 1: that you need to keep you want the blood obviously, 862 00:49:50,320 --> 00:49:52,520 Speaker 1: vampire bats are not going to go around in their 863 00:49:52,600 --> 00:49:56,200 Speaker 1: natural environment drinking blood out of little puddles. Uh, you know, 864 00:49:56,239 --> 00:49:58,000 Speaker 1: so you need to keep it fresh. You need something 865 00:49:58,000 --> 00:50:00,360 Speaker 1: to fresh it up, an anticoagulant see ms to do 866 00:50:00,400 --> 00:50:03,600 Speaker 1: the trick. There apparently have also been experiments with freezing 867 00:50:03,640 --> 00:50:06,600 Speaker 1: the blood, and there's hope that we could eventually create 868 00:50:06,640 --> 00:50:11,239 Speaker 1: a dried powder that could be reconstituted at zoos for 869 00:50:11,400 --> 00:50:14,279 Speaker 1: the bats. So you add water to it and you 870 00:50:14,360 --> 00:50:17,520 Speaker 1: got blood, you know, sort of like a kool aid powder, 871 00:50:17,640 --> 00:50:24,680 Speaker 1: but for blood drinkers. Oh yeah, um, this brings me back. 872 00:50:24,680 --> 00:50:27,640 Speaker 1: I think there's a part in Guillermo del Toro's Blade 873 00:50:27,680 --> 00:50:32,480 Speaker 1: to where like Russian vampires are like snorting lines of 874 00:50:32,480 --> 00:50:35,400 Speaker 1: of like crystallized blood or something or something. You know, 875 00:50:35,440 --> 00:50:38,480 Speaker 1: they're supposed to be crystallized blood. Um. So, I don't know, 876 00:50:38,520 --> 00:50:40,719 Speaker 1: maybe they ran across the same sort of research when 877 00:50:40,760 --> 00:50:44,439 Speaker 1: they were putting together to that film. That's funny. Would 878 00:50:44,480 --> 00:50:48,480 Speaker 1: it be different snorted than it would be just drank? Um? Well, 879 00:50:48,520 --> 00:50:51,360 Speaker 1: I don't know. I mean, it doesn't really, it doesn't 880 00:50:51,400 --> 00:50:55,680 Speaker 1: make a lot of sense that the psychological difference. Yeah, 881 00:50:55,800 --> 00:50:58,000 Speaker 1: I don't know. You get the idea. It's like, as vampires, 882 00:50:58,040 --> 00:50:59,799 Speaker 1: they just like blood. They'll take it anyway they can 883 00:50:59,800 --> 00:51:02,040 Speaker 1: get it. They'll drink it, they'll snort it up their nose, 884 00:51:02,120 --> 00:51:05,240 Speaker 1: they'll freak a bath in it. Yeah, paste the blood, 885 00:51:05,920 --> 00:51:09,440 Speaker 1: smoke the blood. Um. Uh. You know, well whatever serves 886 00:51:09,440 --> 00:51:12,480 Speaker 1: as a useful metaphor for you know, for us to 887 00:51:12,560 --> 00:51:15,360 Speaker 1: use in creating a vampire, like the vampire has addict 888 00:51:15,800 --> 00:51:20,080 Speaker 1: the vampire as as you know, a moral themed etcetera. Now, 889 00:51:20,120 --> 00:51:22,720 Speaker 1: going back to what we're discussing though, in the possibilities 890 00:51:22,760 --> 00:51:26,640 Speaker 1: for for a synthetic blood, if you end up with 891 00:51:26,840 --> 00:51:30,960 Speaker 1: a blood substitute that is actually made from human blood, 892 00:51:31,320 --> 00:51:34,680 Speaker 1: you know, that's the that's depending on the hemoglobin. Uh. 893 00:51:34,760 --> 00:51:37,239 Speaker 1: That would be an interesting scenario, right, because you could 894 00:51:37,280 --> 00:51:41,080 Speaker 1: potentially have fake blood for the vampires to keep the 895 00:51:41,160 --> 00:51:44,320 Speaker 1: vampires at bay, that is actually made from human blood, 896 00:51:44,560 --> 00:51:46,680 Speaker 1: but maybe is like you know, it is the the 897 00:51:46,800 --> 00:51:50,040 Speaker 1: result of of blood bank blood that has not been 898 00:51:50,040 --> 00:51:52,920 Speaker 1: fully utilized. So the vampires might not be really all 899 00:51:52,920 --> 00:51:55,760 Speaker 1: that happy about it. But maybe you know, you wouldn't 900 00:51:55,760 --> 00:51:59,719 Speaker 1: behave be having to just bleed yourself dry for the vampires. 901 00:52:00,120 --> 00:52:03,000 Speaker 1: You would you would have like a secondary product that 902 00:52:03,320 --> 00:52:06,319 Speaker 1: makes them mostly happy. Yeah, they'd be helping us deal 903 00:52:06,360 --> 00:52:10,000 Speaker 1: with medical waste. Yeah, so that would that things kind 904 00:52:10,000 --> 00:52:12,360 Speaker 1: of like a very very much a reduced stature for 905 00:52:12,440 --> 00:52:15,000 Speaker 1: something like Count Dracula. You know, it's like, I know, 906 00:52:15,120 --> 00:52:16,719 Speaker 1: you want to be the Lord of the night and 907 00:52:16,760 --> 00:52:19,319 Speaker 1: you know, drink our blood and have a serview, But 908 00:52:19,400 --> 00:52:22,799 Speaker 1: what if you just gobbled up our medical waste? Are 909 00:52:22,800 --> 00:52:28,359 Speaker 1: you on board? Yes? All right. On that note, we're 910 00:52:28,400 --> 00:52:30,839 Speaker 1: gonna go ahead and close it out here.
