摘要

目的：观察益肾平肝方对SHR大鼠的血压及血清神经肽Y(NPY)、降钙素基因相关肽(CGRP)、内皮素(ET)的影响,探讨其在治疗高血压中的降血压机制方法：将21只12周龄雄性自发性高血压大鼠(SHR)随机均分为3组,即益肾平肝方组(YPR组)、贝那普利组(Bena组)、SHR组,另以同周龄7只WKY大鼠作为正常对照组(WKY组)。各组给予相应干预措施12周后,采用尾套法测量大鼠血压,用酶联免疫吸附剂测定法(ELISA)检测大鼠血清NPY、CGRP、ET的含量结果：SHR组大鼠较WKY组收缩压明显升高(P<0.01)。给予治疗4周、8周、12周后,益肾平肝方组大鼠血压较SHR组明显下降(P<0.01)；与SHR组比较,益肾平肝方组大鼠血清NPY、ET的表达量降低,CGRP表达量增加(P<0.01),且与贝那普利组比较差异无统计学意义(P>0.05) 结论：益肾平肝方可明显降低SHR大鼠收缩压,其机制可能与抑制NPY、ET的表达及增强CGRP 的表达相关。

Abstract

Objective:To observe the effects of “Yinshen Pinggan Recipe” (YPR) on serum neuropeptide Y (NPY), calcitonin gene related peptide (CGRP), endothelin (ET) in spontaneously hypertensive rats (SHRs), and to survey its mechanisms Methods:Twenty-one twelve-week old SHRs were randomly divided into 3 groups (group YPR, group Bena, group SHR), seven age matched male Wistar-Kyoto rats were selected as normal control group (group WKY). Twelve weeks after treatment, the standard blood pressure was tested by tail-cuff measurements. The expressions of serum NPY, CGRP, ET levels were measured by commercial ELISA kits Results:The systolic blood pressure (SBP) was significantly increased in SHRs after 4 weeks, 8 weeks, 12 weeks treatment. And it could be inhibited by Yinshen Pinggan Recipe. In addition, the expression of NPY and ET were significantly increased in SHRs and inhibited by YPR, which increased the expression of CGRP Conclusion:YPR can reduce the systolic blood pressure of SHR, which was associated with the inhibition of the expression of NPY, ET and the activation of the expression of CGRP.
