背景最近的研究建议了表明小径的激活 mitogen 的蛋白质 kinases (MAPK ) 玩的那 p38 在肝的纤维变性的一个重要角色。这研究在 tetrachloromethane 上探索了 oxymatrine 的 antifibrotic 效果在 p38 上的老鼠和它的调整的导致的肝纤维变性 MAPK 发信号小径。120 只健康男 Sprague-Dawley 老鼠随机被分到六个组的方法：正常(n=20 ) ，导致的纤维变性(n=20 ) ，用番红花作原料而制成的植物盐基(n=20 ) 和 oxymatrine (n=20x3 ) 的三个处理组。我们 obesrved 在骨胶原的免职变化，玻尿的酸(哈)， laminin (行)，骨胶原类型( CIV )， procollagen (一种总线标准)和 hydroxyproline (忧郁)，光滑的肌肉肌动朊(-SMA)和 phosphor-p38 ( pp38 ) .Results 在组织病理学说的变化的相对指示物，哈，行， CIV ， PCIli ，忧郁， -SMA 和 pp38 在导致的纤维变性组显著地被提起( P < 0.01 对正常的组)。肝的纤维变性阶段中间的剂量组和高剂量组获得的 semiquantitative 被减少( P < 0.05 并且 P < 0.01 分别地对导致的纤维变性组)是在老鼠的肝的骨胶原的平均区域浆液的集中哈，行， CIV ，一种总线标准和肝织物 homogenate 忧郁。a-SMA mRNA 的基因表示更加在对待的动物被减少，作为是 pp38 的蛋白质 espression 蛋白质。结论 Oxymatrine 在以经由表明小径的 p38 MAPK 联系 fibrogenic 信号 transduction 到 modulating 的方法在试验性的老鼠的肝织物减少骨胶原的生产和免职是有效的。

英文摘要：

Background Recent studies have suggested that p38 mitogen-activated protein kinases （MAPK） signalling pathway plays an important role in hepatic fibrosis. This study explored the antifibrotic effect of oxymatrine on tetrachloromethane induced liver fibrosis in rats and its modulation on the p38 MAPK signalling pathway. Methods One hundred and twenty healthy male Sprague-Dawley rats were randomly assigned to six groups： normal （n=20）, induced fibrosis （n=20）, colchicine （n=20） and three treatment groups of oxymatrine （n=20x3）. We obesrved changes in deposition of collagen, hyaluronic acid （HA）, laminin （LN）, collagen type IV （CIV）, procollagen III （PCIll） and hydroxyproline （Hyp）, a-smooth muscle actin （α-SMA） and phosphor-p38 （pp38）. Results The relative indicators of changes in histopathology, HA, LN, CIV, PCIII, Hyp, a-SMA and pp38 were raised significantly in the induced fibrosis group （P〈0.01 vs normal group）. The semiquantitative hepatic fibrosis staging scores of middle dose group and high dose group were decreased （P 〈0.05 and P 〈0.01 respectively vs the induced fibrosis group）, as was the average area of collagen in rats＇ liver, the concentrations of serum HA, LN, CIV, PCIII and liver tissue homogenate Hyp. The gene expression of α-SMA mRNA was considerably decreased in the treated animals, as was the protein espression of pp38 protein. Conclusions Oxymatrine is effective in reducing the production and deposition of collagen in the liver tissue of experimental rats in ways which relate to modulating the fibrogenic signal transduction via p38 MAPK signalling pathway.
