title: [Cytochemistry and ultrastructure of frog pancreatic exo- and endocrine epithelium under normal conditions].
abstract: The pancreatic epithelium of intact frog has been studied using morphometry, cytochemistry and electron microscopy. A low level of DNA synthesis was shown to be characteristic of pancreatic epithelium of frogs caught in winter. The B/A cell volume ratio is 3.68 +/- 0.16 and 2.55 +/- 0.36 in small and median pancreatic islets, resp. A-, B-, D-cells are found in pancreatic islets, and intermediate acinar A and acinar B cells in intact frog pancreas.
