UNLABELLED: The OBJECTIVE of this research was to investigate the regulatory effect of Epitalon on the production of melatonin and cortisol in senescent monkeys.
MATERIAL AND METHODS: We investigated the character of melatonin and cortisol secretion by immunoferment assay in Epitalon-administered female Macaca mulatta in different age periods.
RESULTS: Epitalon was proven to significantly stimulate melatonin synthesis in senescent monkeys in the evening, thereby normalising the circadian rhythm of cortisol secretion.
