Blood Transfusion - from ignorance to science

Blood as a life-saving medical technology, people have experienced a long history of bizarre ... ... blood transfusion - from ignorance to the science of blood for medical treatment people will fit, is the direct taking of blood from the beginning. Ancient Chinese believed that the deer blood is a good tonic. So starting from the Han Dynasty, the emperor with deer park,[link widoczny dla zalogowanych], spring hunting, riding and shooting for fun, and when needed to kill a deer every day, so the emperor to drink warm deer blood. This booze, little people are naturally not Fu Xiaoshou. But the direct taking of blood, also can play no role in physical healing. 1860 British and French forces invaded Beijing, Chengde Emperor Xianfeng fled, Relative to the Chinese people directly taking animal blood, blood transfusion Europeans in the 14th century, attempts to treat diseases more groundbreaking, but this process is full of ups and downs. Early 15th century, the Roman Pope Nuosheng Te dying, helpless group practice. At that time,[link widoczny dla zalogowanych], a man named Milan Das's doctor said Carew, who entered the blood directly to the Pope, can cure, but it must be virgin's blood, is the most sacred clean. He cruelly cut twelve-year-old boy three arteries, the blood inflow to red copper utensils. 3 children die one by one twitching, miserable. Then, Carew Das adding valuable in the blood of herbs, thick hand-made needle, the blood vessels enter the Pope. Pope immediately felt chest suffocation, soon died. Four lives, this ruined the hands of the quack. From a modern point of view, such a transfusion is tantamount to murder. But, after all,[link widoczny dla zalogowanych], the beginning of blood transfusion person to person, there is still historically positive side. The 17th century, doctors began to people the real blood transfusion. At that time people have a special mouth sheep Ouyang feeling that the most holy blood of clean. As a result, surgeons lose blood of the blood vessels to treat everyone, actually was alive, and it cured some patients with severe anemia, but the success rate of less than 10%. From a number of preserved 17th century oil paintings, you can see blood transfusion with blood of the human scene: a robust Rams are tied on the stool, the neck was shaved hair, cut the carotid artery is inserted a tubes continue to flow out of sheep blood. The other end of the tube is smaller pinhole, gill blood vessels in the patient's wrist. Sheep on high,[link widoczny dla zalogowanych], people lying on the lower, sheep blood for blood flow to the people. However, the results of this treatment is that many patients with sudden suffocation, blood coagulation quickly, not circulation. Sheep and people die too. This terrible scenario can be seen from the paintings. Because of blood so dangerous, it should set a voluntary patient at the book, the statement has nothing to do once they die and doctors. More and more people die, though they are some terminally ill patients, but also aroused shock, as well as the religious court of Paris had to come out intervention,[link widoczny dla zalogowanych], issued an order prohibiting blood transfusion. Thus, patients still return to the old path of drinking blood, drinking blood of the great are there were no significant effects. Until 100 years later, it is only a preliminary figure out the secret of killing sheep blood. In 1875, Lang Teya doctors finally figured out under the microscope causes blood clotting, and that is the main component of blood plasma, blood cells and platelets, the blood of different animals mixed together, can contribute to red blood coagulation. Blood of murder, is the truth. Landmark discovery in 1901. At that time, the Austrian physiologist Lance Tanner's blood found - due to red blood cells contained in the type. Person to person blood transfusion, blood type must be appropriate, otherwise, it will agglutinate red blood cells, deadly serious. This finding restored blood of man by man, saved countless lives. In 1910, scientists discovered strong Gaussian and Moss has AB blood type. AB blood type people who can accept any blood transfusion (and subject to cross-test, no aggregation can be accepted), but it can not be lost to other blood type AB blood type. Later, after another has found that MN, P, RH and other blood type, had a total of 10 kinds of blood. Since then, more safe and reliable blood transfusion was. After 2000 years of exploration, at the expense of countless lives, mankind has an initial understanding of the blood. Through blood transfusion, doctors saved countless lives. But how to correctly use the blood, and further conquest of disease, has yet to be people to constantly explore and research. Edit / Tommy ◆ Welcoming the order of ◆ 2008.9 (on) 29
