Effect of QSYQ on expression of MMP-1 and TIMP-1 in rats with partial abdominal aortic coarctation. (a) Representative photomicrograph of immunohistochemical staining of myocardium. (b) The MMP-1 positive area for each group. (c) The TIMP-1 positive area for each group. The percentage of immunohistochemical staining area was quantitatively analyzed by using Image-Pro Plus 6.0 (magnification, ×400). Data are expressed as mean ± SD. Groups: sham-operated control (), model (), valsartan (), and QSYQ (). , .
