[Evidence of pseudoisocyanine--positive endocrine cells in the gastric mucosa of the dog].
The tunica mucosa of the stomach and the other parts of the intestine (duodenum, jejunum, ileum colon) of the dog has been investigated in order t to demonstrate insulin producing cells. By means of thepseudoisocyanine-reaction it was possible to visualize in the lamina epithelialis of the stomach singular cells containing metachromatically reacting granules. It was possible to distinguish these cells from mast cells localised outside of the lamina epithelialis of the tunica mucosa. The value of this observation is given by the fact that until now hormone producing cells could be demonstrated in the laimina epithelialis of stomach and intestine of mammalia with exception of insulin-producing cells.
