    Abstract:
    OBJECTIVE: To investigate the effects of Tiangou Jiangya capsule on blood pressure of spontaneous hypertensive rats. METHOD: The 13-14 week SPF rats were selected and randomly divided into model groups, the low, middle, high dose of Tiangou Jiangya capsule groups, positive control group administrated with captopril. Drugs were intragastric administrated once per day, lasting four weeks. The blood pressure, heart rate, heart ventricle indexes, urinary volume and the level of PRA,angiotensing II (Ang II), aldosterone (ALD) of rats were observed. RESULT: The low, middle, high dose of Tiangou Jiangya capsule can remarkably reduce the systolic pressure, diastolic pressure and mean arterial pressure of spontaneous hypertensive rats (P < 0.05 or P < 0.01). The low, middle dose can reduce the heart rate of rats (P < 0.01). The low dose can effectively inhibit the left ventricle indexes (P < 0.05). The Tiangou Jiangya capsule has no markedly effects on the renin-angiotensin-aldosterone system (RAAS) activity and urinary output of rats. CONCLUSION: The results indicate that the Tiangou Jiangya capsule has evident effect of lowering blood pressure of rats, which is related to reducing heart rate, heart ventricle indexes, and has no effect on the RAAS and diuresis.
