As of February 2000, 67,340 people were waiting for organ transplants in the United States 8. In 1998, 4,855 Americans on the list were waiting for death 8. A controversial drug, Regitine, is used to protect organs of life supporting patients who are still doing brain activities but are not expected to endure injuries and diseases. Non-heart rate donor (NHBD) was different from the traditional "brain dead" donor in that it is sufficient to stop the heart beat after the technique died of cardiac arrest
Transplant medical care is one of the most challenging and complex fields of modern medicine. Several important areas of medical management are the problem of transplant rejection in which the body has an immune response to the transplanted organ which may result in graft failure and prompt immediate removal of organs from the recipient I need. If possible, serotyping can reduce transplant rejection and determine the most appropriate donor-receptor fit, and by using immunosuppressant drugs
Transplantation is one of the most challenging and complex fields of modern medicine. The major obstacle is graft rejection in which the body recognizes transplanted organs as foreign or non-self and as an immune response thereto. This reaction may cause the transplant to fail. Although the risk of transplant rejection can be reduced, it can not be resolved by using immunosuppressant drugs. Transplant patients are still dependent on these drugs for the rest of their lives. Unfortunately, these drugs have multiple side effects including higher cancer and infection rate.
The main obstacle to HEAVEN is the possibility of a new body immune rejection of the head. Unlike single organ transplantation, head transplantation is a complex tissue allograft (CTA) including skin, muscle, tendon, bone, cartilage, fat, nerves, blood vessels and, of course, the brain. Each organization has varying degrees of antigenicity. As the most powerful organ in the human body, when the skin is recognized as a foreign body, it causes a strong immune reaction. Therefore, in order to judge whether HEAVEN is executable, you need to check attention to other CTAs and see what happens. Hands are a good example. In September 1998, the first manual transplant was performed by a group of surgeons in Lyon, France (later the patient showed psychological rejection and was removed in 2001). Homologous transplants of about 30 people and about 100 upper limbs (including both sides) have been done so far
