[The morphological and morphometric characteristics of the endocrine apparatus of the pancreas at different levels of ovarian hormones].
Changes in morphological and morphometric indices of pancreatic endocrine cells were studied in experiments on mature female rats with a different estrogenic status. Ten days after ovariectomy when the level of female sex steroids in the body was minimum, insulin excretion was slightly inhibited. Endocrine tissue hypertrophy resulted from the formation of new islets and was indicative of adaptation mechanisms. An increase in sex hormones in the estrous phase of the cycle made insulinotropic action.
