[Influence of Tiangou Jiangya capsule on blood pressure in renovascular hypertension rats].

Abstract

OBJECTIVE:

To observe the effect of Tiangou Jiangya capsule (TJC) on blood pressure in renovascular hypertension rats and explore its possible mechanism.

METHOD:

Seventy-two Wistar rats were randomly divided into normal control group, model group, captopril group, TJC small, medium and high dose groups. Non-invasive blood pressure measurement was used to detect the arterial blood pressure of rat tails. PRA, Ang II , ALD, 6-Keto-PGF1alpha, ET and TXB2 content in blood was measured by radioimmunoassay. NO content in blood was determined by method of nitrate reductase.

RESULT:

The systolic, diastolic and mean pressure significantly increased, serum PRA, Ang II , ALD decreased, ET levels significantly increased in model group rats. TJC significantly reduced blood pressure, improved the plasma renin activity, decreased ET levels and increased NO content of model rats.

CONCLUSION:

TJC can reduce blood pressure of renovascular hypertention rats, and the mechanism may be related to its regulating lower blood pressure regulation of the secretion of RAAS system and improving vascular endothelial function.
