Effects of GZD on the myocardial fibrosis in Dahl salt-sensitive rats. a Transmission electron microscopic images of the left ventricle (scale bars: 0.5 µm). b Histomorphological analysis of Masson staining: Bar graphs show the percentage area of fibrosis in the left ventricle (scale bars: 50 µm). c The protein expression levels of MMP2 and MMP9 in the left ventricle were evaluated by western blot analysis. Data are expressed as mean ± SD (n = 8 rats per group). *P < 0.05, **P < 0.01 compared with the NS group; ^#P < 0.05 and ^##P < 0.01 compared with the HS group
