While it’s hard to believe that Soviet scientist Vladimir Demikhov was able to create a two-headed dog, these extraordinary images are proof of that. So how did Demikhov manage to carry out this illogical experiment?
Although Vladimir Demikhov’s experiments may seem rather strange, he was actually a pioneer in organ surgery and inspired the transplant of vital organs. Although he carried out numerous experiments during his career, these two dogs are doing unbelievable practices contributed to his name being heard even more.
Besides these It is also a matter of much debate whether it is ethical or not. Let’s take a closer look at the details of this experiment.
Vladimir Demikhov was one of the prominent figures in organ transplantation in the 30s and 50s.
During the period, Stalin established a number of secret medical facilities to conduct post-war experiments aimed at organ transplantation and lifespan, and He began to support Demikhov.
Meanwhile, this scientist continued to perform heart and lung transplants between animals in his laboratory. Then Demikhov’s colleague Prof. Dr. Performed by AG Konevskiy when the first dog head transplant was successfulDemikhov started to work in this direction.
The Soviet scientist chose two different subjects for this operation.
One was a large German Shepherd dog, which Demikhov called Brodyaga (Russian for “vagrant”), and the other was a smaller breed called Shavka. In this experiment Brodyaga would be the host dog, Shavka would supply the secondary head and neck. Again, the puppy’s head, shoulders, and front legs would be grafted onto Brodyaga.
Dr. Demikhov gave this three-and-a-half hour study to a dog artificially. wearing a blood pump started. He would then attach a second heart to a dog’s chest and remove a portion of the lung for the second heart. Thus, this second heart continued to beat independently of the original heart, maintaining its rhythm for a while.
Also, since the transplanted dog was a puppy, the German Shepherd’s heart was able to pump enough blood in the first place.
Each both heads could see, hear, smell and swallow after this experiment but there was no connection between the small dog and the German shepherd’s stomach. For this reason, everything the little dog consumed flowed down a tube to the ground.
Finally this two-headed dog, lived only four days. If a vein in his neck hadn’t been accidentally damaged, he might have outlived Demikhov’s longest-lived two-headed dog, which survived 29 days.
Even if we leave the deaths of dogs aside, it is possible to say that the moral implications of Demikhov’s experiment are highly misleading.
In addition, although this head transplant seems to contribute to some advances in the field of transplantology, in real life to keep these two dogs alive in the long run It has not yet been proven to be possible.
Based on the experiments of Vladimir Demikhov, the French surgeon Dr. Alexis Carrel and her partner, American Physiologist Dr. Charles Guthrie did the same for the two dogs. Although the double-headed dogs of this duo are promising at first, died within hours and was euthanized.
Most of the medical community nowadays believes that such transmissions are nothing but science fiction but there is always a possibility that it will become reality with the work of scientists in the future.
