A STUDY ON ALTERNATION OF GASTRIC MUCOSAL pH WITH AGING BY ENDOSCOPY

Abstract

Determination of gastric mucosal pH was performed at various spots in the stomach in 286 Japanese healthy subject from 3rd decade to 8th decade. The 14 spots in the stomach were measured by I. S. F. E. T sensor through endoscope. Results were as follows ; 1. Gastric mucosal pH increased with aging significantly at every spot of lesser, greater curvature and anterior wall. 2. From the view point of alternation of the gastric mucosal pH in the same decade, the gastric mucosal pH significantly decreased antrum to upper body of lesser curvature and anterior wall, it demonstrated significant reduction at greater curvature from lower body to upper, but there was no significant change in another age.
