Content of microelements in the rat pineal gland at different ages and the effects of selenium supplementation

The mammalian pineal gland regulates a number of important physiological processes. In this paper we report changes in the content of iron (Fe), zinc (Zn), copper (Cu), and selenium (Se) in the male rat pineal glands at 4, 5, 8, and 12 months of age. The effect of Se supplementation in drinking water on the content of pineal gland microelements was also studied. Selenium (Se)-dependent changes in pineal gland reported in this study suggest novel physicochemical and biochemical properties of Se, an important element essential in the antioxidative processes, yet known to influence a number of endocrine processes.
