Objective The experiment was designed to observe the effect of fructus aurantii immaturus (FAI) on the small intestine motility of mice and the effect of histamine receptor blocker on it.Methods Carbon powder was used to indicate the small intestinal propulsion of mice.Results The enhancing effect of FAI on small intestine motility could be inhibited significantly by diphenhydramine,an antagonist of histamine H 1 receptor.Conclusion The effect of FAI on small intestine might be relevant with H 1 receptor. |
