title: [The effect of pH and pO2 changes in the blood on the energy metabolism of human erythrocytes in old age].
abstract: Changes in pH and pO2 of the blood have been studied for age peculiarities of their effect on the glycolysis rate and the content of ATP and 2,3-diphosphoglycerate (2,3-DPG) in erythrocytes (in vitro). The fresh venous blood of practically healthy young (aged 20-29) and old (aged 75-85) people was used. Acidosis was shown to induce inhibition of glycolysis and decrease of the ATP and 2.3-DPG concentrations in erythrocytes, while alkalosis and hypoxemia-an increase of the glycolysis rate and 2.3-DPG content. In the both cases changes in the indices studied were considerably lower in old people as compared to young ones.
