Outline of Final Research Achievements

The purpose of this research is to elucidate the relationship between diarrhea-improving effect and intestinal aquaporins (AQPs). Using normal rats and magnesium sulfate-induced diarrhea model rats, the influence of goreisan on the fecal water content and intestinal AQPs protein expression were examined. In normal rats, goreisan significantly increased AQP3 and AQP4 protein expression in colon and jejunum. The AQP3 protein expression in the ileum decreased dose-dependently by administration of pentobarbital administration, but the AQP4 protein expression showed no significant change. In MgSO4-induced diarrhea model rats, goreisan decreased AQP3 protein expression and increased AQP4 protein expression in colon significantly.
