[Morphological changes in the gastric and duodenal mucosa in duodenal ulcer in young persons].

Histological investigations were carried out upon the state of the gastric and duodena mucosa in 27 young patients with duodenal ulcer, seven out of them being in the state of exaverbation of the ulcer and 20-in remission. While the duodenal mucosa in the majority of the cases (88.9%) was established to be affected, in 85.2 percent of the patients the gastric mucosa remained intact. The chronic duodenitis observe n 24 of the cases have no atrophic character. The changes in the mucous secretion of duodenal mucosa are in direct correlation with the state of exacerbation or remission of the ulcer process. Similar correlation was not established in gastric mucosa.
