Histopathologic findings of the hearts over time in mice with acute viral myocarditis. (A) Changes in histology of heart over time after CVB3 infection (hematoxylin and eosin stain). Scale bar of panel, 100 µm; (B) Semiquantitative analysis by the degree of myocardial inflammation. Infiltration of inflammatory cells, myocardial necrosis, fibrosis and mineralization was shown at day 7 after the CVB3 infection. In B, data are presented as mean ± SEM and analyzed by one-way ANOVA, post hoc Dunnett test (n = 5 in control; n = 10 in day 3; n = 10 in day 7; n = 7 in day 10). * p < 0.05 vs. control group.
