Correction by peptide bioregulators of micro- and ultramicroscopic changes in the pineal gland caused by stress under light deprivation

Abstract

It has been established, that immobilizing stress causes decreasing of light cell's amount in pineal gland, which are the main source of melatonin production like under usual lighting and like under light deprivation. Light deprivation, that stimulates pineal gland function, also provides activation of pre-melatonin biosynthesis that increased production of endogenous melatonin.
