Activities of antioxidant enzymes, vitamin E level, lactate dehydrogenase isoenzyme spectrum, and effects of melatonin on these parameters were studied in the myocardium of rats aged 6, 12, 18, and 24 months exposed to different illumination regimens. The greatest number of changes was recorded in rats exposed to permanent illumination and light deprivation. Activity of SOD decreased with age, while catalase activity increased. Melatonin treatment did not modify activities of antioxidant enzymes and negligibly modified the level of tocopherol and isoenzyme spectrum of lactate dehydrogenase in rat heart. |
