Dr. Bazalev was a Kazakh doctor who worked in the town of Atrayu. When Nimrod fell of the flying carpet, he was brought to Dr. Bazalev by a local villager. He X-rayed and bandaged Nimrod's head (to which he was very impressed with its size).
Despite leaving Kazakhstan to study medicine in London, he returned to help the locals in Atyaru. It was known that he had several other patients at the same time that he was attending Nimrod.
