Scientists Have Revived The Cells And Even The Circulatory System Of Dead Pigs
American scientists from Yale University have performed an innovative procedure to restore biological functions in pigs that have been dead for more than an hour.
The team restored blood circulation and cellular activity in the bodies of animals that had been anesthetized and then euthanized after a provoked heart attack. The researchers are confident that this method could eventually increase the availability of donor organs.
OrganEx is a modification of the BrainEx extracorporeal pulsatile perfusion system previously used to prevent brain tissue destruction in dead pigs. Then the experts simulated a pulsating blood flow that passes through the blood vessels of the brain at a body temperature of 37 degrees Celsius. As a result, a partial restoration of cellular functions was observed, including the passage of impulses through synapses.
Unlike BrainEx, the new technology is adapted for tissue perfusion not of a separate organ, but of the body of a large animal. It included a perfusion device similar to heart-lung machines and experimental solutions containing compounds that can promote cell health and suppress inflammation in the body. The experiment evaluated the effectiveness of the technology for six hours after one hour of ischemia (stopping the oxygen supply) caused by circulatory arrest due to ventricular fibrillation.
