[Age-specific changes of carbohydrate metabolism in rat liver in immobilization stress].
We have studied peculiarities of the main pathways of glucose utilization in the liver of adult and old rats under immobilization stress. Our data indicate that in both adult and old rats stress is accompanied by an increase in glycolysis intensity in the liver. In stressed adult rats stimulation of glycolysis is associated with metabolism changes characteristic of decreased oxidative decarboxylation of pyruvate in the liver. In immobilized old rats glycolysis stimulation took place in maintanence of effective oxidation of pyruvic acid and enhancement of glucose catabolism in pentose phosphate pathway.
