Abstract:
Objective To evaluate the effects of Yangxue Qingnao Granules (YQG) in decreasing blood pressure in rats with renal hypertension and to investigate its mechanism.Methods Modified Goldblatt renal hypertension rat models were used.The rats were randomized into 6 groups: model group,YQG groups (treated with high-,moderate-and low-dose respectively),Captopril Tablets group and Niuhuang Jiangya Pills group, 10 rats in each group. The model group was given with distilled water and the other groups with corresponding drugs by gavage, once time a day. Blood pressure was detected in 1st, 2nd and 4th week after treatment. Four weeks after treatment plasma levels of endothelin (ET),calcitonin gene related peptide(CGRP) and nitric oxide(NO) were examined by radioimmunoassay.Results Plasma level of ET was increased and those of NO and CGRP were decreased in rats with renal hypertension. YQG could decrease ET level and increase the levels of NO and CGRP, high-dose YQG in particular (P
