[The structure and cytophysiology of the endocrinocytes of the gastric epithelium in a disordered food regimen].
By means of the light and electron microscopic methods the differentiation and the genesis of the epithelium endocrinocytes of the stomach mucous membrane were studied in the albino rats, fasted for 72-144 hours. The deprivation of food is followed by the increase of the number of endocrinocytes and by the change of their ultrastructure. The latter demonstrates the delay of the elimination of the secretory material in some cells (ECL, G, D, D1 cells) while the active functional condition was found in the others (ECL, A-like cells). Exo-endocrine cells with the EC or A-type granules are found in the epithelium, which is regarded as a mechanism aimed at the increase of the number of the appropriate (ECL or A-type of endocrinocytes, participating in the general metabolism of the organism.
