Effect of Qingxin Yangshen Chinese herbs on ?-adrenoceptor in cardiocytes of stress rats / 中华中医药杂志

ABSTRACT

Objective:To investigate the effects of Qingxin Yangshen Chinese herbs on ?-adrenoceptor in cardiocytes of stress rats.Methods:Adopting the method of radoligand binding,the affinity of ?-adrenoceptor of experimental myocardium cells and density were analyzed.Meanwhile,RT-PCR was used to test mRNA of ?-adrenoceptor of myocardium cells.To observe the effect of Qingxin Yangshen Fang on ?-adrenoceptor of myocardium cells of stress rats,and the Zhusha Anshen Pills and Propranololas the control groups.Results:All the three groups above can increase the affinity of ?-adrenoceptor of experimental myocardium cells,promote its sensitivity and notably inhibit the decrease of density of receptors and control down-regulation of expression of ?1-ARmRNA induced by stress,and regulate up the expression of ?2-ARmRNA.Conclusion:The Chinese herbs of Qingxin Yangshen had the effect of acceptor inhibiting and can regulate the changes of ?-adrenoceptor of myocardium cells induced by stress.
