Effects of Methotrexate on Plasma Cytokines and Cardiac Remodeling and Function in Postmyocarditis Rats

Figure 3

Masson’s trichrome staining. Representative photomicrographs of the ventricular sections from the three groups of rats are shown (×200). Green staining represents the collagen fibers (a)–(c). Myocardial collagen volume fraction (CVF; (d)) and perivascular collagen area (PVCA; (e)) were calculated in the control, EAM60 and EAM-MTX groups, respectively. All results are represented as mean ± SD (𝑛=10). ^∗𝑃<.05, ^#𝑃<.01 versus control group; ^▲P <.01 versus EAM60 group.
