Summary
Electron microscopic cytochemical studies of cells of the gastric glands of the stomach reveal enzymatic sites for carbonic anhydrase activity within cells of the gastric glands of hamsters and humans not previously described. The localization of the carbonic anhydrase activity is made apparent by reaction products of lead salts. Numerous electron dense precipitates are evident as discrete circular and irregular profiles and are situated on the outer surface of the mitochondria of the parietal cells. Smaller amounts of the reaction products are seen within the granular endoplasmic reticulum, mitochondrial matrix and on the outer surface of the mitochondria of the chief cells.
