Antioxidant enzymes expression in liver of stressed wistar rat

The antioxidant enzymes (AOEs) expression was studied in Wistar rat liver under two types of stress: acute (immobilization) and chronic (isolation). The acute stress induced increase in blood corticosterone (CORT) and glucose (GLU), but decreased AOEs expression, and such conditions may result in oxidative stress. In contrast to acute stress, in chronic stress conditions, when both CORT and GLU were low, the AOEs expression was markedly induced. This increase in MnSOD, CuZnSOD, and catalase exhibited similar trend implying efficient detoxification of O2 .- and H2O2.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
