Objective To study the effect of Xuefuzhuyu decoction and its seperating prescription on expression of ERK2 mRNA in atherosclerotic vascular smooth muscle cells. Methods The atherosclerosis model rabbits were prepared by high cholesterol diet. The expression of ERK2 mRNA in aortae was delected by hybridization in situ. Results Compared with the blank group,the expression of ERK2 mRNA was remarkably increased in the model group(P〈0.01). Compared with the model group,the expression of ERK2 mRNA was decreased in Xuefuzhuyu decoction group and T...
