The aim of the present study is to investigate the hypotensive effect of Mantidis ootheca (WMO), Rosa laevigata (WIC), and Imperata cylindrica (WRL) in renovascular hypertension rats. Experimental hypertension model is 2-kidney and 1-clip (2K1C) induced rats. 2K1C rats were treated with WMO, WIC, and WRL at dose of 100 mg/kg/day orally for 3 weeks, respectively. Treatment groups with WMO, WIC, and WRL significantly lowered blood pressure. Interestingly, WMO, WIC, and WRL ameliorated endothelium-dependent and independent vascular relaxation in the phenylephrine-precontracted thoracic aorta in hypertension models. In addition, 2K1C-induced hypertension model increased plasma renin activity, however, WMO, WIC, and WRL attenuated those activities. These results suggest that WMO, WIC, and WRL ameliorates vascular dysfunction in 2K1C-induced hypertension models via the regulation of nitric oxide and renin-angiotensin-aldosterone system. |
