Objective:To explore the mechanism of Gonghuanzhixueling on endometrorrhagia caused by Cu-IUD.Methods:In constrast with indomethacin,we made a Cu-IUD-wearing rabbit model and determinated specific viscosity of whole blood,specific viscosity of plasma,hematocrit and blood sedimentation.Results:The hematocrit,the specific viscosity of whole blood and specific viscosity of plasma of rabbits with Cu-IUD were raised,which compared with rabbits without Cu-OID,the difference was marked.Treated with Gonghuanzhixueling,the hematocrit,the specific viscosity of whole blood and specific viscosity of plasm...
