Keyword:  银屑病寻常性α肿瘤坏死因子相关性研究;
Abstract: 目的:研究血清中α肿瘤坏死因子(TNF-α)与寻常性银屑病的相关性.方法:收集症状典型的32例寻常性银屑病患者的血清标本,应用酶联免疫吸附试验(ELISA)检测血清中TNF-α浓度,应用L929细胞检测血清中TNF-α的生物学活性,并与患者的病情、病程、年龄等因素进行相关性分析,同时与正常人的血清检测结果进行对比分析.结果:正常人血清中TNF-α浓度及生物学活性分别为(3.1±6.3)pg/mL及7.9%±5.6%;银屑病患者血清中TNF-α浓度及生物学活性分别为(45.3±86.2)pg/mL及61.8%±10.5%.银屑病患者皮损面积及严重度指数(PASI)的总分与血清中TNF-α浓度及生物学活性均呈正相关.结论:血清中TNF-α水平及其生物学活性与寻常性银屑病关系密切.
