Effect of resveratrol on cardiac fibrosis in left ventricular (LV) myocardium (n = 4). (A) Representative photomicrographs of Masson trichrome staining for interstitial fibrosis showing myocardium in red and fibrosis in blue. (B) Quantification of interstitial fibrosis. (C) Representative photomicrographs of Masson trichrome staining for perivascular fibrosis. (D) Quantification of perivascular fibrosis. Data are mean ± SEM. ^* P < 0.05, ^** P < 0.01 vs. sham rats; ^† P < 0.05, ^†† P < 0.01 vs. banded rats.
