DNA typing of the gastric mucosa of patients with chronic duodenal ulcer

Effect of selective gastric vagotomy on histamine concentration in gastric mucosa of patients with duodenal ulcer.

In a prospective controlled trial, histamine concentrations in human gastric mucosa were determined fluorometrically in 23 patients 6-11 months after selective gastric vagotomy with drainage and in patients who had undergone other types of operation for duodenal ulcer.

Histological changes in the gastric mucosa of chronic gastric ulcer patients treated with carbenoxolone.

Serial direct vision gastric mucosal biopsies were obtained in 25 patients with a chronic lesser curve gastric ulcer. Morphological changes were assessed ;blind' in 15 patients who received carbenoxolone and in 10 untreated patients. Chronic gastritis was initially observed ;proximal' and ;distal' to the ulcer in 24 of the 25 patients. The mucosal changes were shown to persist in subsequent bio...

Helicobacter pylori infection of the gastric mucosa is associated with chronic gastritis, gastro-duodenal ulcer, gastric adenocarcinoma and MALT lymphoma

The prevalence and mechanisms of antibiotic resistance of Helicobacter pylori have not yet been investigated in Uruguay. The objective of this study was to assess the susceptibility of H. pylori to the most frequently used antibiotics and to determine the mechanism of resistance to clarithromycin. Seventy-nine isolates were obtained from gastric biopsies of 50 adult patients during two periods,...
