冬虫夏草（虫草）具有良好的抗肝纤维化作用，然而其抗肝纤维化机制尚不清楚。作者经动物实验证实，虫草能使纤维化肝组织中细胞外基质成份明显减少，可能与其抑制储脂细胞合成细胞外基质（ＥＣＭ）功能有关［１］。作者观察虫草对人成纤维细胞的形态及合成ＥＣＭ的功能影... Cordyceps sinensis (Cordyceps militaris) has a good anti-fibrotic effect, but its anti-fibrotic mechanism remains unclear. The animal experiments confirmed that Cordyceps can significantly reduce the extracellular matrix components in fibrotic liver tissue, which may be related to its inhibition of the synthesis of extracellular matrix (ECM) function of the lipid-storing cells [1]. The authors observed the effect of Cordyceps on the morphology of human fibroblasts and the function of synthetic ECM...
