Moreover, transplantation of donor organs is a highly complex process in medicine still there is a deficit. The fact that most of them are quickly damaged and becomes unsuitable for transplantation, and particularly vulnerable body will be light. Fortunately, researchers from the school of engineering of Columbia and the Vanderbilt University have developed an effective method of restoring light for 36 hours. The method was tested on pig lungs, and should be effective in the case of human organs.
Statistics says that 80% of donor lungs eventually become too damaged to implant. Most often the damage occurs due to the ingress of gastric contents into the respiratory tract, where it begins to dissolve important for lung tissue.
To prevent the destruction of tissue and to maintain the liveliness of the lungs, the researchers applied the method of cross-circulation. In particular, they connected the donor lungs to an animal the recipient to the blood flowing through the damaged tissue and restored them. Using this technology, the researchers kept the light alive for 36 hours.
During this time, cells began to recover and lung function has improved markedly. To the end of the experiment, the light met all quality criteria, which are currently required for transplantation. Before to apply the technology in real conditions, the researchers will evaluate the durability of the restored light, and their reaction to the prescribed after-transplant medications.
A similar experiment in mid-April, conducted by researchers from Duke University — they literally “raised” pig brain four hours after her death. Read more about this achievement of scientists can be read in our material.
