目的 观察牙龈卟啉单胞菌(Porphyromonas gingivalis,Pg)、伴放线放线杆菌(Actinobacillus actinomycetemcomitans,Aa)、大肠杆菌(Escherichia coli,Ec)的脂多糖(lipopolysacchrides,LPS)刺激人牙龈成纤维细胞(human gingival fibroblasts,HGF)合成白细胞介素(interleukin,IL)-11和IL-6的能力,并了解内源性前列腺素是否介导IL-11和IL-6的产生.方法 将3种浓度的LPS(0.1、1、10 mg/L)分别作用于体外培养的HGF 24 h,另外在10 mg/L的LPS中加入10-5 mol/L的吲哚美辛后再分别刺激HGF 24 h,ELISA法检测HGF 上清液中IL-11和IL-6含量的变化.结果 Aa-,Ec-LPS(10 mg/L)和Pg-IPS(1、10 mg/L)刺激HGF后IL-11水平显著提高;Pg-,Ec-LPS(0.1、1、10 mg/L)和Aa-LPS(1、10 mg/L)刺激HGF产生IL-6的水平明显增高;这些作用均受到吲哚美辛的抑制作用.结论 LPS使HGF产生IL-11和IL-6的水平明显增加,并受到内源性前列腺素的正向调控.PubMed中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)0134-364
