Effect of melatonin and time of administration on irradiation-induced damage to rat testes

Abstract: The effect of ionizing irradiation on testes and the protective effects of melatonin were investigated by immunohistochemical and electron microscopic methods. Eighty-two adult male Wistar rats were divided into 10 groups. The rats in the irradiated groups were exposed to a sublethal irradiation dose of 8 Gy, either to the total body or abdominopelvic region using a 60 Co source at a focus of 80 cm away from the skin in the morning or evening together with vehicle (20% ethanol) or melatonin administered 24 h b… Show more

“…In this experiment, melatonin pretreatment resulted in less apoptosis as indicated by a considerable decrease in caspace-3 immunoreactivity. Electron microscopic examination showed that all spermatogenic cells, especially primary spermatocytes, displayed considerably inhibited of degeneration in the groups treated with melatonin before total body and abdominopelvic irradiation (Take et al 2009). An extensive literature implicates cellular DNA as the primary target for the biological and lethal effects of ionizing radiation.…”
