[Morphocytochemical reaction of the main exocrinocytes of the proper gastric glands to orchiectomy].

In the experiment performed on 52 white male rats by means of light and electron microscopy, cytochemistry and biochemistry, it has been stated that bilateral removal of the testes inhibits proliferation of epitheliocytes in the collum of the proper gastric glands and their differentiation into the main exocrinocytes. This results in decreasing amount of the latter and in development of certain destructive processes in them. They concern mainly the protein-synthesizing apparatus and to a less degree the mitochondrial and lysosomal apparatus. RNA content, ATPase activity oxidoreductase of Krebs cycle and pentose-phosphate shunt decreases, and that of glycolysis increase. Pepsinogen synthesis and its extrusion are inhibited; this is accompanied with a decreased proteolytic activity of the gastric juice. Regenerative processes in the main exocrinocytes are also inhibited.
