Abstract

We studied 25 duodenal ulcer patients and 14 age- and sex-matched normal controls to determine whether gastric acid secretion in duodenal ulcer patients is abnormally sensitive to stimulation by gastrin endogenously released in response to meals. Acid response to saline and to 0.5, 1.0, 2.0, 4.0, and 8.0% peptone infused into the stomach was measured by 30 min intragastric titration. Total serum gastrin (G-total) and serum heptadecapeptide gastrin (G17), fasting and 30 min after each test meal, were measured by specific radioimmunoassays. In 19 ulcer patients and 11 normal subjects (controls), acid response to graded doses (11, 33, 100, and 300 pmol kg−1 h−1) of G17-I were also measured.
