Re: Demikhov's Experiments on Dog Head Transplants
On 1954, soviet surgeon Vladimir Demikhov, revealed his masterpiece to the world: a two-headed dog. The head of a puppy had been grafted onto the neck of an adult German shepherd. The second head would lap at milk, even though it did not need nourishment — and though the milk then dribbled down the neck from its disconnected oesophagus. Although both animals soon died because of tissue rejection, that did not stop Demikhov from creating 19 more over the next 15 years. Way before Vladimir Demikhov, Bruyukhonenko's mad experiments on dogs led to the development of open-heart procedures. He developed a crude machine called the autojektor (a heart and lung machine). By using this primitive machine, Bryukhonenko kept the heads of severed dogs alive. In 1928, he displayed one of the heads in front of an audience. To prove it was real, he banged a hammer on the table. The head flinched. When a light was shone in its eyes, the eyes blinked. And when it was fed a piece of cheese, the remnants promptly popped out of the esophageal tube, much to the displeasure of disgusted viewers. |
