title: On the histoenzymology of the human stomach.
abstract: By means of histochemical methods, the stomach in the man was studied for some oxidoreducing enzymes and hydrolases. The surface epithelium displays in the fundic area a mean activity which grows intense in the pyloric area. The parietal cells show a very high mitochondrial dehydrogenase activity, while the chief ones display a moderate oxidative activity. The pyloric glands exhibit a positive reaction for oxidoreducing enzymes with great differences of intensity from one cell to another. Around each principal and pyloric gland one can see an intense ATP-ase reaction in the endothelium of vessels and a very intense acid phosphate activity in the histiocytes. The submucosa, muscularis externa and serosa are very active for oxidoreduction and ATP-ase.
