[Changes in the activity of lipid peroxidation in the myocardium of adult and aged rats under stress].
The levels of lipid peroxidation (LPO) products, the antioxidative system and morphometric changes were studied in the myocardium of adult (8-10-month) and old (20-24-month) male rats in different periods after their exposure to stress. The findings suggest that the maximum damaging action occurs 18-60 hours of poststress. The high activity of LPO and the low activity of the antioxidative system in the hearts of the old animals determine more substantial impact of stress on the myocardium of this group of animals.
