INVESTIGATION OF INSULIN-, GLUCAGON-, SOMATOSTATIN-POSITIV CELLS LOCALIZATION IN THE LANGERHANS’ ISLENDS IN DIFFERENT PERIODS OF BIOCYCLE OF ANURA

Article deals to immunohistochemistry investigation of endocrine cells (insulin, glucagon, somatostatin) localization in the amphibian Langerhans’ islends in different periods of biocycle. In the investigation were used pancreatic glands of three amphibian species (Pipa Pipa L. 1758, Rana temporaria, L. 1758, Rana ridibunda, Pallas 1771). Study showed relationship of quantity of different endocrine cells types is not equal depending on biocycle’s period.
