We studied the histological structure of the adrenal glands within four months after extirpation of the midabdominal gland in newborn hamsters. Structural changes of the cells in all zones of the adrenal cortex suggest development of a compensatory reaction to the midabdominal gland extirpation. Hence, the midabdominal gland was a component of the complex(More)
The development of mouth angle sacciform structure was studied in the ontogenesis of hamster Phodopus campbelli. It was found that the true sacciform structure with all components characteristic for adult animals was formed by the 20th day of postnatal development. Histological data have shown than the sacciform structure is formed in ontogenesis as a(More)
The authors studied in dog experiments the possibility of repairing cranial defects with allografts of bone filings obtained under unsterile conditions, frozen at -70 degrees C, and sterilized by gamma-irradiation in a dose of 3.5 mrad. It was found that though gamma-irradiation reduced the osteogenic inducing property of the bone filings allografts, they(More)
