Scientists consider their experiment a real scientific breakthrough that could change medicine.
The heart, liver and kidneys of 100 pigs continued to function after their death thanks to the intervention of American scientists. They were able to partially restore the efficiency of these organs within a few hours after the death of the animals. Scientists believe that in this way it will be possible in the future to bring dead people back to life, reports the BBC.
Scientists from Yale University, USA, as part of an experiment, euthanized 100 pigs and stopped their hearts. An hour after the death, all the pigs were connected to a special recovery system called OrganEx, and within six hours they were engaged in the return to life of the animals' organs.
Revitalization of organs
To do this, they used synthetic blood to carry oxygen throughout the body, special chemical compounds that prevented the complete death of organ cells, and a special device for pumping blood that imitated the rhythm of a beating heart. After 6 hours, scientists opened the corpses of pigs and it turned out that the heart, liver and kidneys partially restored their working capacity, although they did not act in the same way as when the pigs were alive.
“We were convinced that the restoration of cells maybe you can make organ cells not die,” says Zvonimir Vrsela of Yale University.
How will this help people?
Scientists consider their experiment a real scientific breakthrough that could change medicine. If you apply a similar method to a person, then in this way you can increase the number of organs that can be taken from dead donors. More importantly, in a similar way it will be possible to return the dead, for example, from drowning or a heart attack, to life. After all, doctors will have more time to restore oxygen to their organs.
Cells can be made not to die
When the heart stops working, the body does not have enough oxygen and nutrients to survive. As a result, the cells of the body begin to die. Previously, scientists believed that cell death occurs very quickly and it is impossible to restore them, but a new experiment says otherwise.
“Our experiment showed that it is possible to restore some of the functions of dead cells in the organs of an animal. They should not live a few hours after death, but they function, although not completely,” says Nenad Sestan from Yale University.
Another important point in the course of the experiment was that at some point after the procedure for restoring the working capacity of the organs of the pigs, their necks and heads began to move spontaneously. Scientists believe that it is still necessary to investigate why this happened, but it is possible that some motor functions of the body are also restored after death.
Plans for the future
“There is still a lot of research to be done before this technology can be applied to humans.Our main goal is to preserve human organs for a longer time, so that these organs can be received by living people who need them.Of course, more distant plans are to help doctors bring dead people back to life a few hours after their death,” says Stephen Latham of Yale University.
Focus has already written that in another experiment, American scientists were able to bring the eyes of a deceased organ donor back to life. The researchers believe that their method can be applied to a dead human brain and thus it will be possible to resurrect people.
Focus also wrote that scientists managed to carry out a new pig heart transplant to a human . And this operation was successful.
