Abstract:
ObjectiveTo investigate the effects of Jiuqiang Naoliqing(JNQ) on the morphology of the vital organs(the brain,kidney and heart) in acute hypertension rats.MethodsThe model was established by L-NG-nitro arginine(L-NNA),which can inhibit the synthesis of nitric oxide(NO).Affected animals were administrated with high,medium or low dose of JNQ while nifedipine was used as the positive control.Effects on cardiac function and morphology of the vital organs were investigated.Results2 weeks after the establishment of the model,the affected rats had a 36% higher blood pressure compared with the control group.The acute hypertension rats showed significant pathologic changed in the brain,kidney and heart,while there was no obvious difference in the heart rate,electrocardiaogram,and blood pressure between the administrated groups.After treatment with JNQ,the contraction force and the oxygen extraction of the myocardiocytes were significantly reduced and the increasing velocity of the left ventricular pressure was decreased.The brain,kidney and heart showed improvement in pathology analysis to different levels.ConclusionAlthough it has no obvious effects on the heart rate and blood pressure in acute hypertension rats,JNQ can decrease the oxygen extraction in myocardiocytes and can obviously alleviate brains,kidneys and hearts pathologic changes.
