1.   Previous studies have shown, however, that insulin exerts a stimulatory, rather than an inhibitory effect on intestinal motility.

2.   The dihydroxy bile acids, chenodeoxycholic acid and deoxycholic acid, increase intestinal motility and induce net water and electrolyte secretion.

3.   Both single large doses and fractionated doses of radiation have been shown to alter small intestinal motility in animals.

4.   We used a model of isolated, perfused rabbit terminal ileum to characterise the effects of luminal bile salts on intestinal motility.
