Effects of liguzinediol on extracellular matrix remodeling in MI rats. a The deposition of collagen fibers was stained by Masson (×200). b The level of HYP in myocardial tissue was detected by kits (n = 10). c The levels of collagen I and III in serum were detected by Elisa kits (n = 10). d The expressions of MMP2, MMP9 and TIMP1 in myocardial tissue were detected by western blot (n = 3). Data are shown as the mean ± SD. *P < 0.05, **P < 0.01, compared to Sham group; ^#P < 0.05, ^##P < 0.01, compared to MI group
