摘要 目的:探讨肺结核病变组织-γ干扰素(IFN-γ)表达特征,分析其表达与结核病发展的关系。方法:利用SP免疫组织化学方法.对53例肺结核病变组织和29例正常肺组织中IFN-γ表达进行研究。结果:IFN-γ表达多呈胞浆表达。结核组IFN-γ表达阳性Pu值为3.4917±2.6423,显著高于对照组(1.3286±1.1450,P=0.002)。在结核组中,初治与复治之间,痰菌阳性与阴性之间,空洞与非空洞之间,不同病变范围之间IFN-γ表达差异均无显著性(均P〉0.05)。结论:IFN-γ高表达可能是肺结核病变组织区别于正常肺组织的重要特征之一.与结核病的发生相关,可作为结核病辅助诊断的标志物。
