Correlation between Gastric Emptying Time and the Response of Pancreatic Polypeptide to Test Meals in Peptic Ulcer Diseases

Abstract

KOIZUMI, F., KAWAMURA, T., ISHIMORI, A., EBINA, H. and SATOH, M. Correlation between Gastric Emptying Time and the Response of Pancreatic Polypeptide to Test Meals in Peptic Ulcer Diseases. Tohoku J. exp. Med., 1987, 151(3), 275-281-In the present study, pancreatic polypeptide (PP) levels both in basal state and after stimulation by meal were determined in 21 controls, 28 patients with gastric ulcer and 21 patients with duodenal ulcer and their correlation with gastric emptying was examined. In patients with gastric and duodenal ulcers, basal levels as well as stimulated of plasma PP during 95min of observation period were higher than those in controls except for the values at 5min. As no correlation was seen between integrated PP response (IPPR) to the meal and T_1/2 for gastric emptying in any of three groups, it was indicated that gastric emptying has only a minor role in postprandial PP response.
