[Effect of adaptation to high-altitude conditions on the circadian rhythm of the epithelial mitotic activity in the convoluted kidney tubules in white rats].
It has been established in experiments on 280 white randombred male rats weighing 100-120 g that the lifting of the animals from the valley (820 m above the sea level) to the mountains (3379 m above the sea level) brings about within the first day marked suppression of the mitotic activity of the epithelium of involuted renal tubules. This activity increases beginning from the end of the first week, approaches the control value by the 30th day of adaptation and almost completely returns to normal by the 60th day of the animals' stay in the mountains. The circadian rhythms of the mitotic activity appeared undisturbed and was monophasic in nature.
