摘要: 目的 探索黄芪总甙(AST) 的抗炎作用及其作用机制。方法 采用大鼠角叉菜胶气囊炎症模型, 测定渗出液量、中性白细胞游出数、蛋白质、PGE2、IL-8、NO、PLA2含量以及$\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$的生成量。结果 AST40、80 mg·kg-1 可使角叉菜胶诱导大鼠气囊炎症的渗出液量、中性白细胞游出数、蛋白质含量显著减少, 降低渗出液及中性白细胞中PLA2活性,减少渗出液中IL-8 含量及中性白细胞$\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$的生成。AST 也可明显减少渗出液中PGE2、NO 的含量。结论 AST 的抗炎作用机理与其降低血管通透性和抑制白细胞游出、降低PLA2活性、减少IL-8、PGE2、NO 等炎症介质的产生与抑制氧自由基生成有关。

Abstract: Aim To study the anti-inflammatory effect of astragalosides (AST) and its mechanisms of action. Methods The exudate volume neutrophil count and protein content in exudate were measured in the carrageenan-induced air pounch model in rats. The content of PGE2 was assayed by radioimmunoassay, the activity of PLA2 by microacid titration assay,IL-8 by ELISA,and NO by nitrate reductase assay. The production of $\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$ in neutrophil was determined by cytochrome Cassay. Results AST (40,80mg· kg-1) could markedly reduce the exudate volume neutrophil counprotein content, the content of IL-8, and the production of $\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$. AST lowered PLA2 activity of neutrophil and accellular component in exudate and it also decreased the contents of PGE2 and NO in exudate. Conclusion AST has an obvious anti-inflammatory effect on carrageenan-induced acute inflammation. Its mechanisms may be related to the inhibition of vascular permeability and leukocyte migration as well as to the suppression of PLA2 activity and the reduction of IL-8, PGE2, NO and $\mathop{{O}}_{2}^{{\mathop{}_{\ ·}^{-}}}$ production.
