摘要: 目的 研究黄芪总提物(total extraction of As-tragalus,TEA)对体外脂多糖(LPS)刺激的枯否细胞(KC)基质金属蛋白酶-9(MMP-9)活性的影响 。方法 采用 IV 型胶原酶灌流分离大鼠肝枯否细胞进行原代培养,用lPS 刺激枯否细胞并收集上清液,酶谱法观察TEA 对肝枯否细胞产生 MMP-9 的影响 。结果 TEA (5 ~ 40 mg·L-1)对lPS(1μg·ml-1)刺激的大鼠肝KC 细胞 MMP-9活性有明显的抑制作用。结论 TEA 对体外激活的肝枯否细胞产生 MMP-9 有明显的抑制作用,该作用可能是 TEA 抗肝纤维化的机理之一。

Abstract: AIM: To study the effect of total extrac-tion of Astragalus (TEA)on activity of matrix metallopro-teinase-9 (MMP-9)from Kupffer cells in ratliver.METHODS: The Kupffer cells (KC)were isolated fromlivers of normal rats by in situPerfusionwithPronase and collagenase and density gradient centrifugationwith refrig-erated centrifuger.Then KCwere cultured withlPS (0.1μg·ml-1)and MMP-9 was measured with zymography.RESULTS: TEA (5~40 mg·L-1)could inhibit the ac-tivity of MMP-9 induced bylPS.CONCLUSION: TEA has inhibitory efficacy on activity of matrix metalloprotein-ase-9 (MMP-9)from Kupffer cells in ratliver.
