Abstract
The concentration of immunoreactive somatostatin in acetic extracts of duodenal, antral and fundic biopsies was estimated in 11 subjects with no gastric or duodenal abnormality and 21 duodenal ulcer patients by using a specific and reproducible radioimmunoassay. Somatostatin was detected in the duodenal, antral and fundic mucosa in normal subjects. As compared to the values in the control group, the concentrations in the duodenal ulcer patients were comparable in the antrum and duodenal bulb, and significantly higher in the fundus.
