title: [Seasonal dynamics of adrenal 11-hydroxycorticosteroid secretion in Citellus erythrogenus susliks].
abstract: It has been demonstrated that during different periods of life cycle of the ground squirrels their adrenals produce various amounts of glucocorticoids. Maximum secretion of 11-oxycorticosteroids by the adrenals was noted in active period of animals (May), decreasing to the period of preparation to hibernation (August). During hibernation of the animals, 11-oxycorticosteroid secretion exhibits intrinsic endogenous rhythm. Whereas the first half of hibernation is characterized by a constant secretion (October, November, December), during the second one (from January till March) the secretion of 11-oxycorticosteroids by the adrenals increases.
