[Effect of hypoxia on biochemical parameters of Scorpaena erythrocytes].
Hypoxia effect on the nuclear of the Scorpaena porcus (L.) in vivo was studied. It was shown, that existence of the fishes in environmental with low oxygen concentration-1.3-1.4 mg.1-1 (15% initial saturation) resulted in reducing in activities of Na+, K(+)-ATPase, hexokinase and glucose-6-phosphate dehydrogenase in the erythrocyte for 50.0 (p < 0.001), 26.5% (p < 0.01) and 53.7% (p < 0.05) accordingly. ATP concentration in cells and membrane gradient of Na+, K+ concentrations between blood serum and intracellular environment did not change. A conclusion was made about a decrease of cells membrane penetration and oppression of intracellular metabolism. These changes proceeded on a background of the blood serum dehydration and decrease of the mean volume of erythrocytes. The part of aldosteron and vasopressin in membrane penetration of nuclear erythrocytes is discussed.
