Effects of a Combination of Peptide Extracts From Reindeer Endocrine Glands (Rangifer Tarandus) on the Catholaminergic Regulation of the Estral Function in Rats

Abstract

This study was aimed at investigating the concentration of urinary catecholamines in female rats both in the normal state and during the development of age-dependent changes associated with estrous cycle disorders at early menopause stages. In addition, we set out to assess possible corrective and delayed effects of a combination of peptide extracts from reindeer endocrine glands (Rangifer tarandus) on both phase changes in the estrous cycle and age-related disorders in the functioning of the hypothalamus — adenohypophysis — gonadal system in experimental animals.
