31.   Transit time was calculated as the average passage time of all markers recovered.

32.   In the three responders, initial faecal weight was higher, transit time was shorter, and pH was lower than in non-responders.

33.   They probably work by slowing carbohydrate digestion and absorption, but their effect on mouth to caecum transit time has not been studied.

34.   Both miglitol and acarbose significantly increased breath hydrogen excretion and shortened the mouth to caecum transit time after breakfast compared with placebo.

35.   These results indicate that -glucosidase inhibitors accelerate mouth to caecum transit time by inducing carbohydrate malabsorption.

36.   Thus, the objective of the present study was to investigate the effects of acarbose and miglitol on mouth to caecum transit time.

37.   It has been reported that gastric infusion of bile salts in rats delays gastric emptying and inhibits small bowel transit time.

38.   In addition, infusion of PYY inhibits gastric emptying and prolongs the mouth to caecal transit time in man.

39.   Studies in rats have shown that bile salts inhibit gastric emptying and prolongs intestinal transit time.

40.   In man, infusion of bile salts into the jejunum at physiological concentrations prolongs small bowel transit time and inhibits intestinal motor activity.
