[Dynamics of changes in red blood in rats during acute immobilization]

The standard clinical parameters of red blood, morphometric characteristics, membrane resistance and electrolyte balance of red blood cells of white rats exposed to acute immobilization were investigated. It was found that the immobilization of rats in small-size cages produced statistically significant changes in the concentration of ascorbic acid in the adrenals and oxycorticosteroids in plasma, as well as erythrocytosis, reduction of red blood cell size, planocytosis and decrease of intracellular sodium. The above parameters did not return to the norm 24 hours after 3-hour immobilization. It is suggested to use the amount of plasma per red blood cell as a stress-marker in red blood.
