[The age-related changes in the antioxidant system enzymes of the erythroid cells of swine at the early stages of postnatal development].
The age changes of energy metabolism and antioxidative system enzymes activity in "young", "mature" and "old" erythroid cells of 0-, 1-, 3-, 5-, 10-days old piglets were studied. The essential increase of superoxide dismutase and glutathione peroxidase activities in pig erythrocytes during three days of postnatal life was established. The rise of glucose-6-phosphate dehydrogenase and NADPH-dependent glutathione reductase activities was observed in piglets erythrocytes in the period from 5 to 10 days after birth. The discovered changes of enzymatic activity were particularly characteristic of the "young" cells. It is supposed that this mechanism is essential in erythrocyte membrane structures stabilization in the period of early postnatal adaptation of animals.
