摘要
为研究精氨酸双糖苷(AFG)体外的抗炎机制,以脂多糖(LPS)刺激小鼠单核巨噬细胞(RAW264.7)作为炎症模型,用精氨酸双糖苷(AFG)的低、中、高(5、10、20 mg/L)三个剂量进行干预后,MTT法测定细胞毒性作用,Griess法测定一氧化氮(NO)生成量,ELISA法检测细胞上清液中白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)及前列腺素E2(PGE2)的分泌量。结果表明:AFG的三个不同剂量对RAW264.7细胞无抑制作用(P>0.05),各浓度给药组的NO、IL-1β、IL-6、TNF-α和PGE2含量与LPS刺激模型组相比较都显著降低(P<0.01),推想AFG的抗炎活性可能是通过抑制NO和PGE2等炎症介质释放,降低IL-1β、IL-6和TNF-α等炎症因子的含量而发挥了作用。
In this paper, we studied the anti - inflammatory mechanism of arginyl - fructosyl - glucose (AFG) in vitro. The inflammation model, which was established based on the mouse monocyte- macrophage cells (RAW264.7) stimulated by lipopolysaccharide ( LPS), is intervened by three doses of AFG, low, medium and high (5, 10, 20 mg/L). After intervention, MTI" approach was used to access cytotoxicity; Griess approach is used to determine the amount of nitric oxide (NO) ; and ELISA was used to evaluate the secretion of interleukin - 1 β ( IL - 1β ), interleukin - 6 ( IL - 6 ), tumor necrosis factor - α( TNF - α ) and pros in cell supernatants. The results that: The three doses of AFG have no inhibition effect taglandin E2 ( PGE2 ) on RAW264.7 cells (P 〉 0.05). In the control group, all contents of NO, IL - 1β, IL - 6, TNF -α than placebo group (LPS model) (P 〈0.01 ). The mechanism of AFG in anti contributed by inhibiting the release of inflammatory mediators of NO and PGE2, IL- 6, TNF -α and other inflammatory factors. oL and PGE2 are significant less -inflammatory activity may be reducing the amount of IL - 1β,
