By the way, in many complicated medical cases before this, pig parts have been applied to the patient. It has long been believed that pig parts can be genetically modified to make them suitable for the human body. In this article, we are going to tell you about some such miracles of medical science, in which the parts of the pig were applied to the patient.
Team of Doctors in America has successfully transplanted a genetically-modified pig heart into a 57-year-old man.
A team of doctors in America has done a miracle. This team has successfully transplanted a genetically-modified pig heart into a 57-year-old man. This is the first time in medical history and it is believed that this will help in dealing with the shortage of organ donation.
By the way, in many complicated medical cases before this, pig parts have been applied to the patient. It has long been believed that pig parts can be genetically modified to make them suitable for the human body. In this article, we are going to tell you about some such miracles of medical science, in which the organs of the pig were applied to the patient.
Artificial Vagina prepared with the help of pig intestine
This is the case of the Czech Republic. Doctors treated a woman suffering from a serious problem in her private part in a unique way. This woman’s vagina was so narrow that, far from having sex, doctors could not even do a checkup. In such a situation, the private part of this woman was prepared anew through surgery with the help of pig intestine.
According to the English newspaper Daily Mail, this woman from the Czech Republic had gone to her gynecologist for a checkup. The doctor found that the private part of the woman is so tight that it cannot even be examined. In such a situation, they sent him for treatment to the University Hospital in the town of Plzen in the Western Czech Republic.
After examination here, doctors found that the woman was suffering from scleroderma, in which the skin hardens and shrinks. In such a situation, the doctors decided to use the ‘Mesh Augmented Vaginal Reconstruction Technique’. In this procedure, fresh tissue is applied to the affected area. In this, human skin or pig intestine is used, because pig tissue is soft and their texture is also like human tissue.
Pig skin is used in burn case surgery in China
Scientists in China have developed a new type of skin (human and pig gene hybrid) by combining the genes of pigs and humans, which can be applied on humans. This discovery of scientists is being considered as a milestone for the treatment of victims of burns and acid attacks. The mutant ‘skin’ is another step in that direction, in which pigs are being prepared with organs that can be transplanted into humans.
The artificial ‘skin’ has been developed by a team of Chinese researchers at a hospital affiliated with Nanchang University, led by Lynching Jo. The skin was first tested on macaque monkeys and the results showed that it was able to stay on the original skin of the monkey for up to 25 days.
A woman got a life from a pig’s kidney
scientists in America got a big success regarding xenotransplantation. As an experiment, the scientists transplanted the pig’s kidney to the woman. Not only was this transplant successful, but the kidney also did its job perfectly.
Doctors at Langone Health at NYU (New York University), New York, have transplanted a pig’s kidney into a woman. This kidney was attached to the cells of the woman’s body from outside for 3 days. During this, the kidney performed its normal function.
Doctor Robert Montgomery, who is leading the transplantation team, has said that the pig’s kidney has worked like a normal human kidney. The woman who was transplanted kidney is a brain dead woman. The woman’s kidney was not working properly, due to which she was put on life support. At present, this has been done as an experiment and consent was taken from the woman’s family.
Why Genetically Modified?
Actually, there is a sugar molecule in pig’s genes called glycon, which is not present in humans. Our body treats this sugar molecule as a foreign element and rejects it. Because of this, whenever a kidney transplant was tried before, it failed. To deal with this problem, scientists had already removed this sugar molecule by modifying the genes of the pig. Along with this, the kidney was transplanted by modifying the genes of the pig through genetic engineering.
These efforts also failed.
Efforts are being made for years regarding xenotransplantation. Scientists have already tried to transplant the organs of langur and monkey into the human body. From blood clots to the body’s immune response, the transplantation could not be successful.
In June 1992, for the first time, a langur’s liver was transplanted into a human’s body. The infection had spread throughout the patient’s body only 21 days after the transplant. This infection gradually increased and after 70 days the patient died of brain haemorrhage.
In January 1993, a langur’s liver was transplanted in a 62-year-old man, but he too died after 26 days.
From the 1920s to the 1990s, a lot of work was done in this field around the world. Organs ranging from rabbits, monkeys to langurs were transplanted to humans. After 1990, scientists considered pigs to be the most suitable for xenotransplantation.
