[State of nutritive circulation in rats following long-term limitation of motor activity]

Experiments were conducted on rats. It was shown that long (80-100-day) hypokinesia led to the following significant disturbances of the nutritive circulation: reduction of the true capillary plexus, emptiness of the terminal arterioles and arteries, the direction of the terminal circulation chiefly through the arterio-venous anastomoses, avoiding the nutritive vessels. A tendency to reduction of the buffer bases in the venous blood and to the respiratory alkalosis in the arterial blood was noted. Hemorheological changes were insignificant.
