Abstract
The blood lipid peroxide level of non-exposed and exposed (60-Hz electric field) groups of 8-week-old rats gradually increased over 55 weeks. However, the increasing rate was significantly lower in the exposed rats. In the controls, serum biochemical parameters of the 63-week-old rats related to hepatic function were significantly different compared with those of the young rats. In the exposed rats, the age-dependent differences were smaller and/or disappeared. Electric-field exposure may influence the increase in lipid peroxidation and the alteration in serum enzyme activities accompanying aging.
