The history of science up until the Cold War is often overshadowed by the Manhattan Project. But, today we are going to talk about advances in biomedicine, or healthcare based on a biological understanding of human bodies and diseases.

Thank you SO MUCH for not skipping Unit 731. The atrocities by Japan are so often overlooked. They were maybe worse than the Nazis and we gave them immunity, but no one seems to care.

By "no one" I assume you mean Westerners. Chinese people definitely care.

Especially the manner through which it happened: "We went through the top of the head, I think she was awake. She had a mild tranquilizer. I made a surgical incision in the brain through the skull. It was near the front. It was on both sides. We just made a small incision, no more than an inch." The instrument Dr. Watts used looked like a butter knife. He swung it up and down to cut brain tissue. "We put an instrument inside", he said. As Dr. Watts cut, Dr. Freeman asked Rosemary some questions. For example, he asked her to recite the Lord's Prayer or sing "God Bless America" or count backwards. ... . "We made an estimate on how far to cut based on how she responded." . ... . When she began to become incoherent, they stopped."

@darthmortus5702 5 лет назад

A lot of people are, that is why the doctors and nurses urge you to sit a while after a shot, so as to be nearby if an anaphylactic shock occurs. Ofc I am sure you know this but saying for the benefit of others, I take it they just give you a different class of antibiotics instead of penicillin but that still sucks to have.

It's a bit funny when some racists argue that whites are somehow divine or blessed with more knowledge or morality. Does that mean mixed raced folks are half divine? Another question, do white racists deify people with albinism? Who's whiter than them? This is how you take a depressing historical perspective and make it kinda fun. : P

@nantukoprime 5 лет назад

As the child of a Type I, brittle diabetic, insulin shock and the following insulin coma is what you are trying to avoid. I cannot watch the scene showing the therapy in 'A Beautiful Mind' as I just picture my father being the recipient. It is a slower and less discriminate method of lobotomy. Your body is deciding what parts you need to survive till you are able to raise your blood sugar levels, and memory and higher cognitive functions are just not the priority. It is why the patient has to be strapped down. Science progresses, and scientists need the reminders that sometimes a solution is biased or limited by their current understanding. Thus, implementing the solution should be done with great care.

@iainmackley 5 лет назад

Mildly annoyed that there was a Caduceus instead of a Rod of Asclepius on Charles Drew's gravestone at 8:32. The Caduceus isn't actually used that much by medical professionals, and was symbol of the god Hermes, who was as much a god of medicine as an insurance agent is a medical doctor.

@olaruud9366 5 лет назад

This misconception is so common that in modern usage i suspect it is no longer really separated.

@balisong46 5 лет назад

By professionals it is, but by the common man that is an accurate statement. Lots of shady "medical" businesses use the caduceus unknowing that (ironically) it is a symbol of tricksters. For the US Army it came from printers iconography in medical textbooks. Although, I say its accurate... "Yeah you're good. Just take some Motrin and drink water."

@BubblewrapHighway 5 лет назад

Penicillin should probably be congratulated as one of the greatest heroes of WWII, it's mass introduction and use by the allies probably saved thousands on D-day. It's probably one of the most optimistic parts about WWII, the introduction of this new medicine was truly a miracle that probably did more than any weapon to win the war.

@hedgehog3180 5 лет назад

I think it should also be mentioned that it turned out that most of the research done by the Nazis and Imperial Japan was worthless because of poor methodology, data was often changed to align with ideas of racial superiority and the people used in the first place were often sick and malnourished meaning that they don't represent healthy patients. For example it's pretty obvious that a well fed person is going to deal with cold better. And of course a lot of their theories were just really bad which again makes their research worthless. People try to justify these experiments with "at least we got data out of it" but in reality we didn't even do that and in reality the lesson is that science done without a consideration for ethics is worthless.

@luccamarcal4119 5 лет назад

There seems to be a misconception in Drew’s grave, where there is a Caduceus, that is, actually, not the symbol for medicine but for commerce, instead of the Rod of Asclepius, the greek good of medicine (the mythology behind him is amazing, recommended for everyone who reads this). I see a lot of confusion regarding the symbol for medicine, which, as a Brazilian med student, makes me a little sad, because the symbol is purposely chosen to be the symbol of the god of medicine as a reminder that, as much as physicians are dedicated to their jobs, death is not a thing for mortals to control, that, so far, there has never been someone that died and came back to life. Beautiful symbology.

@ThZuao 5 лет назад

Glad you didn't left out Unit 731. People seem to forget Japan was as bad, if not worse than Nazi Germany; I believe for the sake of supporting the "USA bad" narrative because of those two nukes. But let's not forget that Eugenics, or at least the populational control bit, was commonplace and advocated for in the scientific comunity, basically for Malthusian motives. Germany just happened to take it to the next level and actually do it, basing their whole existential philosophy around it and spicing it up with some Genocide, then lose a war aghainst basically the whole damn planet.

That is a very important distinction to make.
