And there was yet another discovery too, one that gets to the very heart of the subject matter: that there were some individuals who completely lacked the Rh Factor. The most significant – and also deeply worrying – side-effect of being Rh negative relates to the matter of pregnancy.Actually, it’s the one and only adverse side-effect: giving birth aside, being RH negative has no major, adverse bearing whatsoever upon matters relative to health.This latter issue of a close tie between Rhesus macaques and people is why so much research into human diseases and viruses is undertaken on macaques, which is very unfortunate for the macaques.As someone who cares a lot about animal rights, I find this very unsettling. Landsteiner and Weiner – during the course of their studies – elected to inject the blood of the Rhesus macaques into other, very different animals, including both guinea pigs and rabbits.
They are what are termed “Old World Monkeys” and can be found across much of south and central Asia, their territory extending from Afghanistan to China.
It was not until the dawning of the twentieth century that the first, initial steps were taken to fully understanding the precise nature of blood.
As incredible as it may sound, experiments to transfuse blood from human to human, and from animal to animal, date back as far as the mid-1600s.
Despite the ups and downs of these early experiments, right up until the latter part of the 19 Century matters were very much misunderstood on the issue of blood – and, very often, tragically so, too.
This all became acutely clear during the turbulent American Civil War of 1861 to 1865, in which no less than 600,000 individuals lost their lives, as north and south went to war in violent and bloody fashion.
As a result, transfusions in the United States were seen as being very much a last resort; in much of Europe of the 1800s, however, blood transfusions were viewed not as a last resort, but as a definitive no-go area – period.
