1. Serum gastrin concentrations before and after a standardized meal were determined in twenty-eight patients with duodenal ulcer and in ten normal control subjects. 2. In response to pentagastrin, thirteen of the duodenal ulcer subjects secreted acid within the limits of normal and fifteen secreted in excess. 3. The differences in the basal serum gastrin concentrations between the three groups...

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. So...

The population incidence of perforated gastric and duodenal ulcer has been the subject of several studies (Illingworth, Scott, and Jamieson, 1944; Jamieson, 1955; Pulvertaft, 1959; Weir, 1960). Although some concerned 'peptic ulcer' incidence it is clear that gastric and duodenal ulcer perforation rates should be considered separately because the incidence of the two lesions differs (Jennings, ...

The effect of different extracts of leaves and fruits of Moringa oleifera Lam. (Moringaceae) on gastric and duodenal ulcers was evaluated by using different gastric ulcer models and cysteamine-induced duodenal ulcer method. The leaf extracts (500mg=kg, p.o.) of Moringa oleifera showed gastric ulcer healing effect in acetic acid–induced chronic gastric ulcers. The acetone extract and methanol ex...

The prevalence of peptic ulcer disease in the general population of Kashmir, India, was determined by endoscopy in a randomly selected sample population of 2763 adults aged 15 years and above who were interviewed using a questionnaire. Of 239 persons with ulcer symptoms, 193 (80.7%) had an oesophagogastroduodenoscopy. A randomly selected 177 individuals from among the remaining population witho...

Aspirin is generally regarded as a cause of gastric ulcer but the role of non-steroidal anti-inflammatory agents and paracetamol in the aetiology of peptic ulcer is unclear. To investigate this we conducted a case control study of 180 matched pairs of peptic ulcer patients and controls obtained from surgical and dermatology outpatient clinics. There were 95 gastric ulcer and 85 duodenal ulcer p...

The aim of this study was to determine the effect of Helicobacter pylori eradication on the natural history of duodenal ulcer disease, and to determine the incidence of reinfection in adult patients where H pylori had been eradicated in a community with a high prevalence of the infection. An investigator blinded study, with 24 month endoscopic follow up, in subjects where H pylori had been erad...

This study tests the hypothesis that reactivation of a latent herpes simplex virus infection may be a cause of recurrent duodenal ulceration. Patients with recently healed duodenal ulcer were entered into a double blind, randomised study of maintenance treatment with the antiviral drug acyclovir (400 mg bid) versus placebo, to determine if suppression of herpes virus infection would influence t...

BACKGROUND AND AIMS Factors predisposing to endoscopic ulcer formation or healing with non-steroidal anti-inflammatory drugs (NSAIDs) have not been well defined. METHODS We used multivariate analysis of data from three large similar trials to identify factors associated with endoscopic lesions and healing. We compared the effectiveness of omeprazole 20 mg and 40 mg daily, misoprostol 200 micr...
