ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of salvianolic acid B (SAB) on the proliferation of human embryonic lung fibroblast MRC-5, and the secretion of procollagen I and endogenous transforming growth factor-beta1, (TGF-beta1).</p><p><b>METHODS</b>The MRC-5 cells were randomly divided into four groups as follows: the control group: cells cultured with DMEM but with no TGF-beta1, or SAB; the TGF-beta1, group: cell cultured with 10 ng/mL TGF-beta1; the SAB1 group: cell cultured with medium with 10 ng/mL TGF-beta1 and 1 pmol/L SAB; the SAB2 group: cell cultured with medium with 10 ng/mL TGF-beta1, and 10 pmol/L SAB. The proliferation of cells was assayed by MTT incorporation. The concentration of amino-terminal propeptide of type I procollagen (PINP), a marker of collagen synthesis, was measured by radioimmunoassay. The endogenous TGF-beta1, levels were measured using ELISA.</p><p><b>RESULTS</b>The optical density, procollagen I contents, and endogenous TGF-beta1, levels significantly increased when compared with those of the control group (P<0.05). Compared with the TGF-beta1, group, the optical density was obviously lowered, the procollagen I contents and endogenous TGF-beta1, levels significantly decreased in the SAB1 group and the SAB2 group, and better in the SAB2 group, showing statistical difference (P<0.05).</p><p><b>CONCLUSIONS</b>SAB could inhibit the proliferation of MRC-5 cells induced by TGF-beta1 and attenuate the roles of secreting collagen and endogenous TGF-beta1. It had the potential of postponing or delaying the progressive developing of pulmonary fibrosis.</p>
