Figure 5: (a) The representative protein product of p-EKR extracted from the left ventricles of excised hearts in hamsters of control, cholesterol and Li-Fu formula groups were measured by western blotting analysis. (b) Bars represent the relative protein quantification of p-ERK on the basis of α-tubulin. All bars indicate mean values ± SD ( in each group). ** , significant differences between control and cholesterol groups. ## , significant differences between cholesterol and Li-Fu formula groups.
