title: [Transmural potential and a profile of intestinal motility in dogs].
abstract: Relationships between motor patterns of the jejunum and transmural potential changes were studied in the dog chronically fitted with transparietal electrodes and with an intraluminal catheter. The transmural potential increases above 13 mV at the beginning of the irregular spiking activity of a myoelectric complex and reaches 6 mV at the end of  a phase of regular spiking activity. Oscillations of 3 mV are recorded during the phases of irregular spiking activity. A sustained increase of the potential occurred after feeding : 10 mV for a diet rich in protides and fat, 25 mV when glucides are predominant.
