Objective:To observe the effect of Tianwang Fuxin tablets on the TLR4 expression in the ischemic myocardium of rats with coronary artery ligation and to investigate its possible action mechanism. Methods:A myocardial ischemia model was established by ligation of the coronary artery in rats, which were randomly divided and given medicine for 21 days. Immunohistochemistry and PCR were used to observe the effect of Tianwang Fuxin tablets on the TLR4 expression in the ischemic myocardium of rats. Resuhs:Tianwang Fuxin tablets can regulate the pr...
