Interpretation of fluctuation of transmural potential difference across the proximal small intestine

David Wingate, Roger Green, John Symes, Marianne Pilot
PMCID: PMC1412966  PMID: 4430469

Abstract

The duodenal transmural potential difference (pd) has been studied in isolated vascular-perfused preparations of canine stomach and duodenum. There was no quantitative correlation between the magnitude of the intraluminal pressure change and pd but fluctuations of pd in these preparations were related to duodenal slow wave activity.
