Abstract:
Objective To observe the effects of total flavones from Herba Epimedii(TFHE)on the experimental myocardial ischemia and hemorheology of animals.Methods The model of acute myocardial ischemia of rats was established with pituitrin and the model of acute blood stasis was established with high-molecular dextran.The effects of TFHE on the electrocardiogram J-point of acute myocardial ischemia model and the hemorheology of acute blood stasis model were observed.Besides these,the effects of TFHE on coaglutaion time in mice were observed.Results As compared with the model groups,high-,middle-,and low-dosage groups(24,12,and 6 mg/kg)of TFHE could obviously improve the abnormal electrocardiogram J-point of acute myocardial ischemia model,also could effectively prevent the ascending of whole blood viscosity(high-,middle-,and low-shear rate),packed erythrocyte volume,and fibrinogen.High-and low-dosage groups(34 and 17 mg/kg)of TFHE could obviously lengthen the coaglutaion time in mice.Conclusion The results suggest that TFHE possesses protective effects on ischemic myocardium,which may better hemorheology,decrease the whole blood viscosity,prevent blood from coagulating and improve the circulatation of coronary artery.
