title: [The morphology of the endocrine portion of the amphibian pancreas].
abstract: It has been shown that the endocrinous part of the pancreas in amphibia is formed of A-, B- and D-cells. B-cells are always disposed around sinusoid capillaries, while A- and D-cells lie on the islet periphery and often have no contact with capillaries. In addition to islets in the pancreas there are remnants of the so-called "external" epithelium which is represented by solitary B-cells, located in the wall of small excretory ducts. In the periinsular zone there are numerous acino-islets of A-, B- and D-types among which B-cells are prevailing.
