[The ultrastructure of the main exocrinocytes in the glands proper of the gastric mucosa in A avitaminosis].
The electron microscopic and morphometrical methods were used to study the ultrastructural organization of main exocrinocytes of the proper glands of the mucous membrane of the stomach of rats under conditions of A-avitaminosis. Deficiency of vitamin A causes dystrophic alterations of main exocrinocytes. The fragmentation, degranulation and considerable dilatation of cisterns of the granular endoplasmic reticulum, destruction of the Golgi complex membranes, disturbance of the membranous organization of secretory vacuoles were observed. A conclusion is made of disturbances of the protein-synthesizing function of main exocrinocytes under conditions of A-avitaminosis.
