In the history of human science experiments, scientists in various disciplines have carried out many crazy experiments, especially in the last century, due to the imperfection of relevant laws, the closure of information transmission and frequent wars, some scientists even directly carry out experiments that endanger human health, threaten life safety and immorality, such as sensory deprivation experiments, children's electric shock experiments, bacterial injection experiments, twin suture experiments, cryonics experiments and severed head resurrection experiments.
Since the beginning of the twenty-first century, scientists around the world have rarely used humans as dangerous experimental objects, but use a variety of animals, the most common of which is mice. That's right, the white fat and cute mice accidentally mixed into the worst animals in the history of biological evolution.
Back in the last century, there was a famous scientist in the Soviet Union named Vladimir Dmykokhov. During World War II, Dmykokhov worked in a Soviet Red Army hospital, treating many wounded soldiers. After the end of World War II, the Soviet Union issued an order that its own medical experts should defeat the Western countries led by the United States in the field of medicine at all costs.
After receiving the order, Dmikokhov began to specialize in scientific research projects in organ transplantation. Over the course of his decades-long research career, he and his colleagues conducted a series of animal organ transplant experiments, mainly on dogs. At the time, these experiments seemed very cutting-edge, even crazy.
In 1946, Dmikokhov performed the world's first heart-lung transplant for a puppy, and later he transplanted almost all the body organs in the puppy. In 1952, Dmikokhoff's "live dog for heart" operation was finally successful, and the puppy survived for 5 months, which shocked the top American leadership.
For a long time, scientists around the world have been fiercely debating a medical puzzle, that is, after the human heart stops beating, how long it will take for the brain to lose consciousness and die. Demykohoff, a medical expert, is of course involved in the debate, and his view is that it takes about 1 hour for the brain to die after the heart stops beating.
To prove his point, Dmykokhov drowned a dog in a pool whose heart stopped beating. 26 minutes later, Dmikokhov miraculously revived the dog using artificial respiration, blood transfusions and other measures, restoring consciousness to its brain. He later did the same experiment several times, resurrecting a puppy that had been dead for 45 minutes for the last time.
One of the wildest and most famous experiments Dmikokhov ever conducted in his scientific career came in the mid-fifties. In this experiment, Dmikokhov carefully selected a robust German Shepherd and made an incision in the back of its neck. At the same time, he amputated a puppy named Shafka from below the front leg.
Dmikokhov then "grafted" the two puppies together through vascular connections and skin suture surgery, turning them into a two-headed dog.
Thanks to the preparation and experience, the procedure was completed in only 3 and a half hours. Miraculously, the two-headed dog after the operation is normal in terms of sight, hearing and smell, and the two dog heads can eat independently.
Dmikokhov noticed that the two-headed dog's second head was able to eat milk, and the milk flowed smoothly into the body along the incoherent esophagus.
What's even more amazing is that the two heads of this two-headed dog sometimes tear each other, I don't know if they are playing with each other for fun or really fighting.
Unfortunately, the two-headed dog did not live long. Because a vein in its neck ruptured, it survived less than a week before dying. According to Dmikokhov's estimates, if this blood vessel had not ruptured, the two-headed dog could have survived for at least 1 month.
Subjectively speaking, using two healthy puppies for such a crazy experiment is indeed very cruel and immoral. But objectively speaking, animal experiments like this have accumulated rich experience and made great contributions to the development of human medicine.
