title: [Endocrine apparatus of the duodenal epithelium in chronic gastroduodenitis in children].
abstract: Ultrastructural organization of the endocrine apparatus of the duodenum in children suffering from chronic gastroduodenitis was studied on 15 biopsies, and its involvement in pathological process is shown. Signs of the functional activity enhancement on the one hand and those of damage on the other hand are observed in the cells. Apart from that, poorly differentiated endocrine cells and "mixed" endocrine and exo-endocrine cells which can be considered as a manifestation of endocrine elements recovery appear in the duodenal epithelium.
