Abstract

The present study examined the effect of a methanol extract of Evodiae Fructus on the cardiovascular function in N-nitro-L-arginine methyl ester (NAME)-induced hypertensive Wistar rats after treatment over 6 weeks. In rats treated with NAME, blood pressure, weight of heart, aorta media thickness and media/lumen ratio significantly (p<0.05) increased, whereas coronary flow and heart rate of isolated heart significantly (p<0.05) decreased compared with control group at 6 weeks. In rats treated with NAME and Evodiae Fructus, blood pressure, aorta media/lumen ratio significantly(p<0.05) decreased compared with NAME treated group at 6 weeks. These results suggest that Evodiae Fructus is applicable to the treatment of hypertension and vascular hypertrophy.
