title: [Features of the ultrastructure of endocrine and immunocompetent cells of the antral portion of the stomach in patients with grade II-III obesity].
abstract: 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.
