Abstract It is now evident that hypersecretion of gastric hydrochloric acid is an important pathogenetic element among a variety of heterogeneous factors responsible for the production of common duodenal ulcer. Hypersecretion of gastric acid due to usually strikingly increased circulating levels of gastrin released from gastrinoma tissue is characteristics of patients with to Zollinger-Ellison Syndrome. In contrast, fasting serum gastrin levels are normal in patients with common duodenal ulcer. The polypeptide hormone, gastrin does, however, appear to play subtle and multiple roles in enhancement of gastric acid secretion in duodenal ulcer. Recent evidence suggests that abnormalities in gastrin release and action may be influenced by participation of somatostatin. The hypothesis is proposed for consideration and for further investigation that the multiple subtle abnormalities in gastrin release and parietal cell sensitivity to gastrin may be due to disturbances in the actions or concentrations of locally acting polypeptides, substances which are capable of suppressing gastrin release and its effects (somatostatin), or alternatively, are capable of stimulating release of gastrin into the circulation (bombesin).
