[Comparative histochemical study of insulinocytes and Paneth cells].

Histochemical reactions of insulocytes and Paneth cells of rabbits and rats were investigated following the injection of the agents selectively affecting the above cells, as well as of glucose, a specific stimulant of insulin secretion. The data obtained suggest a functional relation between the pancreatic islet cells and the intestinal cryptic basal regions, which is mediated by the mechanisms, involved in regulation of the glycemic level.
