[Pancreatic insular function in peptic ulcer patients].

Radioimmunological assay was used to study the content of insulin and C-peptide in the blood bath in conditions of basal incretion and 1 and 2 hours after a test breakfast in 12 healthy subjects, 36 patients with duodenal ulcer and 20 patients with chronic atrophic gastritis. It was found that patients with duodenal ulcer showed an increased hormonal activity of the pancreas leading to exhaustion of its reserve capacities. In patients with chronic atrophic gastritis reserve hormonal capacities of the pancreas were maintained and somewhat elevated.
