摘要
目的研究人工麝香水提物对脂多糖(LPS)刺激小鼠单核巨噬细胞RAW264.7释放炎症因子的影响,为建立体外评价模型奠定基础。方法采用酶联免疫吸附法测定细胞上清液中白介素(IL)-6、IL-10和肿瘤坏死因子α的含量。结果不同剂量的人工麝香水提物可明显降低LPS引起的细胞分泌IL-6、IL-10和肿瘤坏死因子α的含量。结论在LPS刺激单核巨噬细胞RAW264.7释放炎症因子模型中,人工麝香水提物可明显降低炎性因子的释放,可能是其抗炎作用的主要机制之一。
Objective on lipopolysaccharide-stimulated cytokines secreted or released by RAW264. 7 cells. Methods Cytokines inclu- ding intedeukin （IL） -6, IL-10, and tumor necrosis factor α were determined using cytokine enzyme-linked immunosorbent assay kits. Result Compared with model group, the levels of major cytokines such as tumor necrosis factor α, IL-6, and IL-10 significantly decreased in different AME groups in a dose-dependent manner. Conclusion In lipopolysaccharide-stimulated RAW264. 7 macrophages, AME can remarkably inhibit the re- lease of inflammatory cytokines and thus exerts its anti-inflammatory effects.
