ABSTRACT
Objective To observe the effect of Fuxin Mixture(FXM) on the ß,-AR(adrenergic receptor) -cAMP(cyclic adenosine monophosphate, cAMP) -PKA ( protein kinase A, PKA) pathway of rats with heart failure. Methods Male Wistar rats were randomly divided into blank control group, captopril group, FXM low dose group, FXM high dose group and model group.Models of CHF were established. After drug intervention for 6 weeks, the left ventricular mass index (LVMI) was analysed, the expression of ß1 - AR mRNA in myocardial tissue was measured,the level of cAMP in rat plasma,the OD value PKA content of spleen tissue homogenate were detected. Results Compared with the blank control group, the LVMI and the cAMP in plasma of model group were increased (P <0. 05), the expression of ß1,-AR mRNA, the OD value of spleen tissue homogenate and PKA were decreased (P <0. 01). Compared with the model group, the LVMI were decreased,and the expression of ß1-AR mRNA were increased in FXM high dose group and captopril group (P <0. 01 , P <0. 05) ; the level of cAMP in plasma of each drug group were decreased (P <0. 01) , the OD value of spleen tissue homogenate and PKA were increased (P <0. 01). Compared with the captopril group, the expression of ß1-AR mRNA, the OD value of spleen tissue homogenate and PKA were decreased, and the LVMI and the cAMP were increased in the FXM low dose group (P <0. 01 , P <0. 05). Compared with the FXM low dose group, the LVMI and the cAMP of FXM high dose group were decreased (P <0. 05), the expression of ß1-AR mRNA, the OD value of spleen tissue homogenate and PKA were increased (P <0. 01). Conclusion FXM could play the role of anti-heart fail- ure through regulating P1-AR-cAMP-PKA pathway.
