摘要:

目的:探讨成纤维细胞(FB)与细胞间粘附分子-1(ICAM-1)在口腔粘膜下纤维化(OSF)发生中的可能作用。方法:分别从正常(NM)及OSF患者的口腔粘膜中培养出FB,向培养基中加入不同浓度的槟榔提取物(ANE)培养48 h后,用细胞酶联免疫方法检测FB表达的ICAM-1水平。结果:表示ICAM-1水平高低的OD值在OSF-FB为01386? 01099,高于NM-FB的OD值01324?01030(P<0105);ANE在50~150Lg/ml的范围内以浓度)效应依赖关系刺激 FB产生ICAM-1。结论:ANE能上调FB表达ICAM-1的水平,提示ICAM-1及其介导的细胞与细胞或细胞与基质间的相互作用在OSF的发生、发展中可能起重要作用。

Abstract:

Objective:The study aimed at investigating the effects of areca nut extracts on the levels of ICAM-1 expressed by the oral fi- broblasts.Methods:The fibroblasts were obtained from normal buccal mucosa and buccal mucosal with submucous fibrosis and cultured in vitro. The levels of ICAM-1 expressed by fibroblasts incubated with/without ANE in the presence of 10% fetal calf serum in the mixed gas of 5% CO2and air at37efor48 h, were monitored using cell-based ELSA.Results:The fibroblasts ob- tained frommucosalwith oral submucous fibrosis expressed ICAM-1 at a high level. ANE increased the expression levels of ICAM- 1 in both fibroblasts obtained from normal and abnormal mucosa.Conclusion:The high expression levels of ICAM-1 in the fibrob- lasts of oral submucousfibrosis and ANE stimulated the expression of ICAM-1, whichmay be one of the importantmechanismswhy lymphocytes become localized and retained atthe side of connective tissue during inflammation and lead to activation of fibro
