Morphology and Pathomorphology


The mucosa of the fundal and pyloric portions of the stomach in chronic gastroduodenal ulcer is shown to exhibit structural and functional heterogeneity. Regularities of the regenerative-plastic reactions in the epithelium are revealed from the indexes of3H-uridine and3H-thymidine incorporation. Inflammatory-sclerotic changes of the gastric mucosa showed different proliferative and metabolic activity of epitheliocytes.
