LOCALIZATION AND DISTRIBUTION OF ENDOCRINOENTERIC CELLS IN THE STOMACH OF PIGS DEVELOPING ESOPHAGOGASTRIC ULCER

The morphology, distribution and behaviour of entire endocrinogastric cell populations were studied in healthy pigs and in pigs developing a n experimentally induced oesophagogastric ulcer. Polymorphic endocrine cells were interpolated between other glandular cells and distributed scattered along fundic and pyloric glands. In relation to the control animals, the endocrine cell count in ulcerous pigs was decreased in t he pyloric but increased in the fundic mucosa. It is hard to determine which type of endocrine cells pertaining to the total Grimelius-posit ive population affects the cell count in this pathological condition d ecisively, before additional immunocytochemical evaluation.
