[The surface status of the gastric mucosa in retinol deficiency].

Changes of the stomach mucosa in retinol deficiency of the organism were studied by methods of scanning and transmission electron microscopy. Observation of stomach mucosa state of the animals was performed in dynamics (in proportion with increase of the vitamin deficiency). The disturbance of integrity of the apical part of the external cell membrane of the superficial epithelium and development of apical erosions in cells were established. Disturbance of integrity of the external membrane apical part in epitheliocytes provides erosions and ulcers development in retinol deficiency.
