Duodenal pH values in normal controls and in patients with duodenal ulcer.

چکیده
Recent studies by Wormsley and Mahony (1967) and by Banks, Dyck, Dreiling, and Janowitz (1967) have shown that the ratio between the secretory capacity of pancreatic bicarbonate and gastric acid is lower in duodenal ulcer patients than in normal subjects. It has therefore been suggested (Wormsley and Mahony, 1967; Rovelstad, 1956) that duodenal neutralization is insufficient in this disease. Some studies have supported this theory by demonstrating higher duodenal pH values in normal controls than in subjects with duodenal ulcer (Kearney, Lomfort, and Osterberg, 1941; Atkinson and Henley, 1955; Archambault, Rovelstad, and Carlson, 1967). Other studies, however, have not been able to show such a difference (Rhodes and Prestwich, 1966) and this question can still be considered open. The present study investigates this problem further by measuring fasting and postprandial duodenal pH values in normal and ulcer subjects. By selecting the cases so that the two groups did not differ with respect to gastric secretory capacity, a possible difference due to the gastric hypersecretion usually associated with duodenal ulcer could be eliminated.

متن کاملSerum Leptin Level in Patients with Duodenal Ulcer
Background: Leptin and its receptors have been found in the human gastric mucosa. Its secretion by gastric mucosa has generated interest in its probable role in the gastrointestinal tract and pathophysiology of diseases. Objective: To determine any possible correlation between serum leptin level and pathological findings in patients with duodenal ulcer (DU). Methods: In a cross-sectional study...

متن کاملEffect of intragastric pH on antral gastrin and somatostatin release in anaesthetised, atropinised duodenal ulcer patients and controls.
The synchronous change in the antral release of gastrin and somatostatin into a vein draining the stomach was studied during acidic and alkaline intragastric pH in six anaesthetised duodenal ulcer patients and six controls after atropinisation. No differences in the basal secretion of gastrin and somatostatin were observed among the two groups. Alkaline as well as acidic intragastric pH had no ...
متن کاملDoes Ramadan Fasting Increase duodenal ulcer perforation?
Introduction: In Ramadan, healthy adult Muslims are obliged to fast. Prolonged fasting increase gastric acid and pepsin levels, which promote the risk of duodenal ulcer perforation (DUP). Effects of Ramadan fasting on DUP have not been thoroughly studied yet, and the limited number of studies investigating the impact of Ramadan fasting on DUP yielded discrepant results. This study aimed to eval...
