    Abstract:
    The rate of lipid peroxidation (LPO) in erythrocytes and brain homogenate has been assessed by the accumulation of malondialdehyde, the degree of erythrocyte autohemolysis, the content of hydrogen peroxide and catalase activity observed in newborn rats aged 1 hour, 1, 15, 20 and 30 days. Pregnant rats were exposed to emotional stress (aggressive interaction of two pregnant rats in an unavoidable conflict situation provoked by nociceptive irritation. Significant age-dependent differences in the rate of LPO (both in erythrocytes and cerebral tissue) have been found. The highest rate was noted in rats 15 days of age. The emotional stress of pregnant females resulted in the changes of behavioural reactions of newborn rats and LPO activity that was characterized by the increase in LPO rate in 1-hour- and 1-day-old rats and by slowing of LPO rate in 15-day-old rats. These phenomena were observed in erythrocytes and brain tissues of test animals.
