[Effect of stress on the content of free radical oxidation products in subcellular brain fractions in rats of pubertal age].

The purpose of the present work is to study the influence of immobilization stress of different intensity on the content of protein and lipid oxidation products in subcellular brain fractions in rats of different age. It has been shown that 30-minute immobilization of 1.5-month, 2-month- and 12-month-old rats was not accompanied by accumulation of protein and lipid oxidation products in subcellular brain fractions. A prolonged immobilization of 1.5-month-old rats was accompanied by manifestations of oxidative stress in subcellular brain fractions; such manifestations were not characteristic of the rats of older age groups.
