[Age-related characteristics of poststress DNA repair in the myocardium]

It has been demonstrated that young and adult rats had age-associated differences in stress-induced lesions and in poststressor repair of DNA synthesis in the myocardium. In both age groups, the DNA repair systems perform an identical scope of work aimed at abolition of poststressor lesions with the difference that in young rats, the repair is completed 2 days and in adult rats 3 days after exposure to stress is discontinued.
