Indicators of LPO and Antioxidant Protection in Rats During Long-Term Restriction of Motor Activity

This article presents a comprehensive study of the parameters of LPO (concentrations of malondialdehyde, diene conjugates, and intensity of chemiluminescence) and antioxidant defense (concentrations of α-tocopherol, ceruloplasmin, total antioxidant activity, antiradical activity, and activities of antioxidant enzymes — superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase) in blood plasma and erythrocytes of white male rats during restriction of motor activity up to 28 days. The patterns of changes in oxidative balance in hypokinesia in the form of intensification of LPO processes against the background of depletion of resources of antioxidant defense with maximum manifestation on days 14-21 of the experiment were revealed.
