On this day, 45 years ago, August 6, 1980 (June 26, 1980, the research on artificial blood in my country was successful in Shanghai. On August 6, 1980, my country's research on artificial blood was successful in Shanghai. This was successfully trial-produced after five years of research by scientific workers from the Shanghai Institute of Organic Chemistry, China Academy of Sciences and the Third Military Medical University of the China People's Liberation Army. Artificial blood is an ultra-fine emulsion of fluorocarbons in water. In 1966, American scientist Clark discovered that there was a mouse in a container containing fluorocarbons. When he took out the mouse and drained the fluid from its respiratory tract, the mouse actually woke up. After repeated research, he found that the liquid's ability to dissolve oxygen and carbon dioxide is 20 times and 3 times that of water, respectively. Clark was inspired by this: the liquid could be used instead of blood. In 1979, a new type of fluorocarbon emulsion was used as artificial blood for the first time in Japan in human single kidney transplantation and was successful. Not long after, the United States also reported that artificial blood was successful in treating blood diseases in a religious elderly man who refused blood transfusions. This wonderful artificial blood is white; regardless of blood type, people can use it regardless of blood type, so we say that artificial blood is a truly universal blood. The successful development of artificial blood has taken a new step in the development of my country's pharmaceutical industry. However, compared with blood in the human body, artificial blood has many shortcomings. It cannot transport nutrients, does not have the ability to coagulate blood, and has no immunity that is crucial to external infections. Therefore, it is necessary to develop a substitute like human blood. It will take a lot of effort. my country's pharmaceutical industry takes a new step
