Abstract: | Serum gastrin, serum insulin, plasma noradrenaline, plasma adrenaline, pulse rate and blood pressure were measured repeatedly during 24h in six patients with duodenal ulcer and in six control subjects. Mean serum gastrin concentration was 3-4 times higher in duodenal ulcer patients than in controls during both the day and at night. Serum insulin was the same in both groups of subjects. Overnight fasting and mean supine plasma noradrenaline as well as mean supine pulse rate were significantly higher in duodenal ulcer patients than in controls. Plasma adrenaline and arterial blood pressure were the same in patients and controls. These results suggest that sympathetic nervous activity is increased in patients with duodenal ulcer. The increased sympathetic nervous activity may mean that duodenal ulcer patients are subject to more stress than normal subjects or may be compensatory to increased vagal nervous activity presumed by some authors to be present in such patients. |
