According to British media reports, Italian neuroscientist Sergio Canavero announced that after nearly 18 hours of surgery, he and the team of Harbin Medical University of China successfully succeeded the head of one body with the spine of another body. , blood vessels and nerve connections.
Huang Jiefu said that in the last century, scientists had transplanted a head and transplanted a dog's head to another dog. The dog died less than one day after surgery. So far, animal head transplant experiments have never been successful.
Huang Jiefu pointed out that medicine does not recognize the scientific nature of skull transplantation. There are two insurmountable technical problems in the theory of skull transplantation. One is to restore the neck, bones, nerves, lymphatic vessels, etc. seamlessly to the original state. There are many spinal cords. Channels, cluttered, impossible to connect after disconnection, and central neurons are impossible to regenerate, this is a technically insurmountable obstacle. There is also the problem of immune rejection. The body transplant requires a large dose of immunological drugs, which has great side effects, so it is a problem that cannot be solved at all.
"After the skull transplant, it is the head or the body to identify this individual. At present, there is no ethical conclusion." Huang Jiefu said that from the medical ethics, the first thing to consider is whether it can be done, but should not, there is no evidence in the experiment. There is no basis for science. Animals do this on the basis of no success. This is a fear of life. (China News Network)
