[Motility and absorption of glucose at the level of the small intestine of sheep].

Relationships between the basic motor patterns of the small bowel, i.e. the occurrence at hourly intervals of myoelectric complexes and absorption of glucose were studied in vivo on 2-m length ovine jejunum isolated loops by means of the "perfusion marker" technique. For a mean flow rate of about 480 ml/h, the net glucose movement during queiscence was decrease at the occurrence of the phase of irregular spiking activity (ISA) and increased during the phase of regular spiking activity (RSA) of the myoelectric complex. When the flow rate was nearly halved (225 ml/h), the net absorption of glucose was decreased at the occurrence of the phases of either ISA or RSA of the complexes.
