ABSTRACT
<p><b>OBJECTIVE</b>To investigate the anti-fibrotic effects of Qishen Yiqi Dropping Pills (QYDP) in rats with liver fibrosis (LF).</p><p><b>METHODS</b>The LF model was induced by intraperitoneal injection with dimethylnitrosamine (DMN). Sixty Wistar rats were randomly divided into the normal group, the model group A, the QYDP intervened group , the model group B , and the QYDP treated group B. The degree of LF was evaluated according to 6-phase grading method. The expressions of collagen type I and III and tissue inhibitor of metalloproteinase-1 (TIMP-1) in liver tissues were determined by immunohistochemistry and the levels of collagen type I and III and TIMP-1 mRNA determined by semi-quantitive RT-PCR.</p><p><b>RESULTS</b>Compared with the model group A and B, the degree of LF, the positive expressions of TIMP-1 mRNA and the content of collagen type I and III in liver tissue in the QYDP intervened and treated groups were significantly lower.</p><p><b>CONCLUSION</b>QYDP could reduce the pathological changes and degree of LF in rats, which may be partially through inhibiting the expressions of collagen type I and III and TIMP-1.</p>
