[Relationship between intestinal motility and absorption. Electromyographic study in the dog. (author's transl)]

Abstract

The effects of different food components on intestinal motility were studied by means of an electromyographic technique. The electrical activity of the small intestine in the fasted state consists of a cyclic recurring phenomenon - the myoelectric complex - which is inhibited by feeding. The duration of inhibition of the myoelectric complex was shown to depend on the nature of the food components (glucose, peptides or lipids) as well as on the caloric load. In the opposite, the intensity of the intestinal motility was seen to depend only on the nature of the food components, and not on the caloric load. Thus, the duration of inhibition of themyoelectric complex can be considered as a consistent and objective parameter, which reflects the duration of the fed state.
