[Effects of taurine and enalapril on blood pressure, platelet aggregation and the regression of left ventricular hypertrophy in two-kidney-one-clip renovascular hypertensive rats].

In two-kidney-one-clip (2k-1c) renovascular hypertensive rats, the blood pressure, left ventricular weight/body weight (LVW/BW) ratio and blood platelet aggregation were increased significantly. Enalapril (Ena) 6 mg . kg-1 . d-1 ig 9 wk and Taurine 30 mg . kg-1 . d-1 ig 9 wk can not only decrease the high blood pressure, LVW/BW ratio, but also the blood platelet aggregation induced by ADP or thrombin, though still different from that of the normal group. When the 2k-1c renovascular hypertensive rats were treated with both Ena and Tau, the blood pressure and blood platelet aggregation were decreased to the same as that of the normal group, and the LVW/BW ratio was also lowered markedly, though still higher than that of the normal group. These results show that both Ena and Tau can reverse the left ventricular hypertrophy, decrease the blood pressure and suppress the blood platelet aggregation in 2k-1c renovascular hypertensive rats. When treated with both drugs, the effects can be improved. It suggests that the two drugs can enhance the effects when used together, and that they may be two good agents for treatment of hypertension.
