Figure 4

Effect of curcumin on M1 and M2 macrophage marker protein expression in the myocardium at 7 days post-MI. (a) Representative immunohistochemistry detection of M1 macrophage marker (iNOS) expression; (b) representative immunohistochemistry detection of M2 macrophage marker (Arg1) expression; (c) quantification of iNOS-positive cells; (d) quantification of Arg1-positive cells. Seven mice in each group. Data were shown as the ; was vs. the sham group, and # was vs. the MI group. And value was calculated by Student’s -test.
