Objective: To observe the pharmacodynamics of Xueminning Granule (XG) on hemorrhage of upper digestive tract.Methods:Applying pylorus-ligated stomach ulcer model on rats; gastric mucosa injury induced by absolute ethy1 alcohol on rats and stomach ulcer induced by reserpine on mice to investigate the stomach ulcer-preventive effects of XG; applying the gastric juice analysis to investigate the mechanism of XG;applying the coagulation time test and bleeding time test and platelet count on mice to investigate the hemostatic effects of XG. Results: obviously prophylactico-therapeutic effects on three stomach ulcer model were found; the ulcer index and gastric juice output were decreased; the coagulation time and bleeding time were shortened.Conclusion:pharmacodynamics basis of XG on hemorrhage of upper digestive tract were provided.
