An Energy Metabolism Study on the Efficacy of Naoxintong Capsules against Myocardial Infarction in a Rat Model

Figure 2

Effect of NXT on the left ventricular remodeling of the ischemic myocardium. (a) HE staining of myocardial tissue of each rat group (20×). (b) Immunohistochemical staining for IL-6 and TNF-α. (c) Masson staining of myocardial tissue of each rat group (0.6×). The blue stain indicates infarct area (collagen); the red stain indicates myocardial fibers. (d) Quantification of the infarct size using the equation: . (e) Quantified immunohistochemical staining of IL-6. , , model group vs. sham group; , , treated group vs. model group.
