摘要:目的? 研究蹄叶橐吾醇化乙酸乙酯萃取物(EEOLF)对金黄色葡萄球菌的抗菌消炎作用。方法? 测定EEOLF对金黄色葡萄球菌的最小抑菌浓度(MIC);取正常培养的巨噬细胞RAW264.7为空白组,采用金黄色葡萄球菌作用于RAW264.7细胞建立体外实验模型(模型组)。细胞活/死染色观察EEOLF(剂量为5 μg/ml)作用于模型组后细胞的损伤情况,ELISA法测定EEOLF(剂量为1.25、2.5 及5 μg/ml)作用于模型组后IL-1β及TNF-α的释放量。结果? EEOLF对金黄色葡萄球菌生长有抑制作用,最小抑菌浓度为1300 μg/ml;当金黄色葡萄球菌作用于RAW264.7细胞后,细胞发生严重损伤,同时IL-1β及TNF-α的分泌量增加(P0.05),当药物浓度为5 μg/ml时,炎性因子L-1β及TNF-α的分泌量下降(P0.05). When the drug concentration was 5 μg/ml, the secretion of inflammatory factors L-1β and TNF-α was decreased (P<0.05), and the cell damage was improved.Conclusion? EEOLF can inhibit the growth of Staphylococcus aureus and alleviate the inflammatory response caused by Staphylococcus aureus, and its antibacterial and anti-inflammatory effects are worthy for further study. ......
