[Features of the ultrastructure of endocrine and immunocompetent cells of the antral portion of the stomach in patients with grade II-III obesity]. / Osobennosti ul'trastruktury éndokrinnykh i immunokompetentnykh kletok antral'nogo otdela zheludka u bol'nykh s ozhireniem II-III stepeni.

All types of endocrine cells that occur in healthy persons were identified in the mucous membrane of gastric antrum of patients with obesity. Ultrastructural changes in endocrine cells in obese patients are suggestive of degenerative processes: in D-, D1- and G-cells these are fatty, P- and EC-cells albuminoid. Endocrine cells containing granules characteristic for cells of several types were found more frequently than in control patients. However such mixed types were observed in the two above groups of endocrine cells. Infiltration of mucous membrane of gastric antrum with lymphocytes and activation of intraepithelial lymphocytes and their interaction with endocrine cells were more pronounced in obese patients.

[Secretory and morphological state of the stomach in alimentary obesity patients kept on a low-calorie diet]. / Sekretorno-morfologicheskoe sostoianie zheludka u bol'nykh alimentarnym ozhireniem, nakhodiashchikhsia na nizkokaloriinoi diete.

The authors studied gastric secretion in 117 persons with alimentary obesity of degree II and III along with the morphological picture of the gastric mucosa. The secretion was investigated by the fractional method, pH-metry and without tubage. In the majority of patients with alimentary obesity gastric secretion proved to be normal. In these patients a greater appetite was not associated with an intensified secretion. In all of the cases under examination the morphological picture revealed the presence of chronic gastritis.
