Abstract
Regional gastric flow can be measured by hydrogen clearance. This method permitted the simultaneous measurement of flow in the mucosa, submucosa and muscularis of both the antrum and corpus in anesthetized dogs. The main advantage of this method compared with other techniques used for gastric microcirculatory studies is that it offers the opportunity of repeated flow determinations in an anatomically identical area under various experimental conditions.
