“…The stimulatory effects of pineal hormones on melatonin production have been proven in rats [6], old primates [1,7], and elderly humans [2]. In addition, numerous experimental studies have shown that peptide preparations fromn the pineal gland inhibit age-associated changes in the mechanisms of neuroendocrine regulation and reproductive function, correct disorders of carbohydrate and lipid metabolism, improve the immune and antioxidant status, and exhibit clear-cut oncostatic and geroprotective effects [1,4,[7][8][9]. On the other hand, the effi ciency of long-term use of peptide preparations from the pineal gland in rapidly aging elderly patients is a very interesting problem.…”
