    Abstract:
    Post-prandial intestinal motility, analysed through two electromyographic parameters, duration of inhibition of myoelectric complex (DIMC) and percentage of spike potentials (PSP), was studied after ingestion of glucids, proteins and lipids. Post-prandial intestinal motility depends on both chemical nature and caloric load of nutriments: DICM depends on those two factors but PSP only depends on nature of nutriments. Post-prandial intestinal motility also depends on route of administration of nutriments. Intra-jejunal administration versus intra-duodenal administration increases DIMC observed for glucids and proteins, diminishes DIMC observed for lipids and diminishes PSP observed for glucids and proteins. These results indicate a specificity of intestinal post-prandial motility with characteristics of nutriments. Intestinal digestion and absorption of nutriments, just as hormonal secretion in response to intestinal passage of nutriments could explain such a specificity.
