Histochemical, biochemical, and histophotometrical studies of carbonic anhydrase activity have been carried out on the stomach of the various vertebrate classes, in order to make functional comparisons. Our results on carbonic anhydrase activity of epithelial surface may be interpreted in favour of a protective role by the secretion of an alkaline fluid against damage due to intraluminal low pH values. As regards the presence of carbonic anhydrase in the different types of gastric glandular cells, in addition to the already known function of the enzyme in hydrochloric acid secretion in the oxyntic and oxyntic-peptic cells, we suggest an interpretation of carbonic anhydrase presence observed in many chief cells.

Abstract

Histochemical, biochemical, and histophotometrical studies of carbonic anhydrase activity have been carried out on the stomach of the various vertebrate classes, in order to make functional comparisons. Our results on carbonic anhydrase activity of epithelial surface may be interpreted in favour of a protective role by the secretion of an alkaline fluid against damage due to intraluminal low pH values. As regards the presence of carbonic anhydrase in the different types of gastric glandular cells, in addition to the already known function of the enzyme in hydrochloric acid secretion in the oxyntic and oxyntic-peptic cells, we suggest an interpretation of carbonic anhydrase presence observed in many chief cells.
