Background: Recently, exploring novel dietary nondigestible carbohydrates, which are able to influence the gut flora, has drawn much attention. The objective of this study was to find out the effective dose of levan, as a prebiotic, in rats in order to further apply it in the food industry. Methods: Levan at various doses (2-10%) was orally administered to male Wistar Albino rats once a day for...

Background: The appropriate colon cleansing is a major determinant of quality of colonoscopy. The aim of this study was to compare the efficacy and tolerability of the morning (AM) PEG (polyethylene glycol) solution to previous-evening (PM) PEG solution for the afternoon colonoscopy. Methods: This comparative study compared the AM to PM prep for afternoon outpatient colonoscopy. The subjects r...
