Carried out a successful transplant pig hearts baboons
A large group of scientists from several institutes in Germany, Sweden, Switzerland and the USA pigs transplanted baboon heart and keeping them alive for a long period of time. In his article published in the journal Nature, the scientists describe the changes they have made to the heart transplant procedure, and how well they worked.
As the population in developed countries is gradually aging, health services are faced with a growing number of health problems, among which recently took heart damage due to cardiovascular disease.
Currently, the only treatment for these patients is a transplant. But wishing every year - or even vitally dependent on a new heart - people more and more. Many die while waiting for a donor. Perhaps pig hearts transplanted baboons, take root, and one day will be able to save people's lives.
Help pigs baboons
Previous studies have shown that there are two main reasons why the pig heart do not survive in baboons: injuries that occur during the procedure, and the difference in size. Scientists have found that the usual procedure for preservation of heart after the removal of the animal prior to transplantation meant his immersion in cold water. However, this method damages the heart tissue. To prevent damage, researchers are periodically pumped blood solution was mixed with nutrients and hormones, and supplemental oxygen. This will keep the heart.
The researchers also gave the baboons drug stops the heart growth, and blood pressure was adjusted to the level of the swine. By combining different methods, the researchers found that they could extend the life of baboons. Two of them lived for three months - on the duration of the study - and the other two lived for six months before being put to sleep.
