Human experiment of artificial blood

However, the success of animal experiments does not mean that it is completely applicable to the human body. This kind of artificial blood was later trial-produced by Japan Green Cross Pharmaceutical Company, and on the basis of perfluoronaphthalene fluorocarbon, many substances necessary for human body were added to make a white emulsion, which was named "fluosol-DA". Who will do the human experiment? Ryuichi Naito, the manager of the pharmaceutical company, decided to try it on himself first. He was injected with 50CC first, and he felt good about himself without any abnormal reaction. Increase the injection amount, 100CC, 150CC, 200CC, still safe and sound. So others began to take the exam voluntarily, from 200CC to 1000CC, and there was nothing uncomfortable. When the body was examined four weeks later, the artificial blood components were basically excreted and replaced by newborn blood made from human bone marrow. So Japan announced that artificial blood was made for the first time in February 1979. By April of 1979, a patient with massive blood loss in Japan successfully used this artificial blood for blood transfusion. In this way, the Japanese boarded the chief throne of successful trial production and application of artificial blood. And China has carried out research, and when it was successful, it was only one year behind Japan and won the second place in artificial blood. It was jointly developed by Shanghai Institute of Organic Sciences and the Third Military Medical University and successfully applied in Shanghai Zhongshan Hospital.

Artificial blood has been successfully produced, and there have been more than 50 successful cases of human hematopoietic transfusion in the world, which have reached the level of approval for formal application according to health regulations. Therefore, the supply of artificial blood will soon replace human blood donation, which is really great news today when the blood source is tight. There is no difference in macaque factors, so there is no blood type. Everyone can transfuse blood, and it can be mass-produced in a pharmaceutical factory like an injection. It can be preserved for three years, and its oxygen permeability is twice that of real blood. Of course, compared with real blood, artificial blood still can't keep up with the performance. There are no biological substances such as white blood cells, platelets, antibodies and enzymes in some of the components mentioned above. Therefore, it has antibacterial, coagulation, immune and other functions. None of them are available, and it is impossible to use everyone to do blood after blood drawing. Because the rest of the functions have to be maintained by real blood, it is impossible to completely cancel human blood donation at one time. All countries continue to study and compete in making artificial blood with functions close to true blood. Once this nearly fully functional artificial blood is made successfully, it can be used to treat patients with various blood diseases. For example, aplastic anemia has always been an incurable disease. The famous Madame Curie died because of this disease, and there is nothing the famous doctor can do about it. But artificial blood can cure this disease. If you keep injecting artificial blood, you will survive. Another example is sepsis, which is terminal. If the blood breaks, it's all over. However, once the fully functional artificial blood is successful, you can remove all the diseased blood and replace it with artificial blood to circulate in the body, so that you can still work alive. But by that time, the finger was cut, and it was not bright red blood, but milky white liquid. Experts estimate that by the end of this century, bionic artificial blood close to true blood function may come out, and the medical field will be completely new.
