Abstract
The rate of lipid peroxidation and activities of superoxide dismutase, catalase, and hydrophilic antioxidants were studied in the hypothalamus, liver, kidney, myocardium, skeletal muscle, and serum of Citellus pygmaeus upon entering hibernation (18–20°C), in early torpor (7–10°C), and after hibernation for a week or three months (5–10°C). During hibernation, lipid peroxidation proved to either decrease or remain at the level characteristic of waking animals. High antioxidant activity was maintained in most tissues, particularly, in the case of prolonged hibernation.
