Effects of QSYQ on pathomorphism of myocardium. (A) Representative photomicrograph of hematoxylin and eosin (H&E) and mason trichrome staining of myocardium. (B) The inflammation with a histological score for each group. (C) The collagen volume fraction for each group. The collagen volume fraction was quantitavely analyzed by using Image-Pro Plus 6.0 (magnification, ×100). Data are expressed as mean ±SD. Groups: control (n=8), model (n=8), valsartan (n=8), QSYQ (n=8). Data are expressed as mean ±SD. * P<0.05, ** P<0.01.
