Organs Transplantation in Humans

Transplant is the transfer of cells, tissues or organs from one donor life to others or the recipient. Or transplantation from one part of the body to other body parts such as liver transplantation, with the aim to return liver function has been lost. Transplant can provide a significant advantage for those who suffer from diseases that can not be cured. Blood transfusion is a transplant of the most frequently performed.

Liver transplant success rate is lower than kidney transplant, but 70-80% recipients survive for at least 1 year. Those who survive the most is the recipient of his heart had suffered damage from primary biliary cirrhosis, hepatitis or drug use that is toxic to the liver. Liver transplantation as a treatment for liver cancer is rarely successful. Cancer is usually re-grow on the transplanted liver or other organs and less than 20% of recipients who survived for 1 year. What is surprising is that the reaction of rejection in liver transplant rejection reaction is not as good as in other organ transplants (such as kidney and heart).

But after the surgery should be immunosupresan given drug. If the recipient have an enlarged liver, nausea, pain, fever, jaundice or have liver function abnormalities can be identified from the results of blood tests, it can be done biposi needle. Biopsy results will help determine whether the transplanted liver has been rejected and whether the drug dose should be increased immunosupresan.

Organ transplants typically involve a suitable donor search, due to potential risks of surgery, use of drugs immunosupresan the potent, the possibility of rejection by the recipient's body and the possibility of complications or death. For those vital organs such as heart, lungs, liver, kidney or bone marrow) is not working properly and function can not return to normal, then the organ transplant may be the only opportunity for survival.

Tissue or organ donor may come from other people who are still living or recently dead. Is the preferred tissue derived from the people who are still alive because of the high success rate. But the heart, liver, lung and eye components (cornea and lens) can only come from someone who had just died, and usually by accident rather than because of illness. Part of the liver tissue have also been transplanted from a donor who was still alive. Transplant organs from living donors performed within a few minutes after the organ removed. Some organs last only for a few hours outside the body, whereas other organs can be stored in a refrigerator for several days.
