[Lipid peroxidation in thyroid tissue of people with diffuse toxic goiter]. / Peroksidnoe okislenie lipidov v tkani shchitovidnoi zhelezy liudei, bol'nykh diffuznym toksicheskim zobom.

The processes of lipids free-radical oxidation in euthyroid and thyrotoxic tissue samples of human thyroid gland were studied. It was shown, that the content of TBA-active lipid peroxidation products was considerably increased in thyrotoxic tissue of the thyroid, and the activity of antioxidant enzymes (catalase, glutation peroxidase) was decreased in it. Possible mechanism of the tissue lipoperoxide alternation under conditions of the thyroid hyperfunction is discussed.
