[Effect of insulin on electric activity of sheep jejunum]

The effect of insulin on the electrical activity of the small intestine was studied in both normal and alloxan induced diabetic sheep. In normal animals the migrating myoelectric complexes recur at intervals of about 90 min. In the diabetic sheep, the complexes recur at only 2 hourly intervals and administration of insulin restored the pattern to normal. Since in normal sheep, insulin slightly increases the activity and volatile fatty acids, which release insulin do likewise, one may conclude that insulin may control the activity of the gut.
