Figure 5: Effects of EA on the expression of ERK1/2 and p-ERK in cardiac muscular tissue in rats for each group ( each group). Western blotting was performed on protein extracts from left ventricular myocardial tissue. Quantitative analysis revealed a significant increase in model group while decrease in EA groups. However, there was no statistical significance difference between PC6 group and LI4 group. versus normal; versus model; versus PC6.
