近几年来,肿瘤坏死因子(Tumor Necros Factor, TNF)在一些免疫性疾病的发病机制中已引起临床和科研工作者的广泛兴趣。而有关测定血清和胸水中TNF比值测定国内外报道不多,为此,我们进行了探讨,观将我们的结果报道如下。 对象和方法 一、对象:癌性胸水34例(男28,女6),平均年龄42.5岁(18～77岁),均为肺癌病人。结核性胸水31例(男20,女11),平均年龄36岁(17～61岁),所有病例均经X线、CT、细菌学、病理切片等证实)。全部 In recent years, tumor necrosis factor (Tumor Necros Factor, TNF) has attracted widespread clinical and scientific interest in the pathogenesis of some immune diseases. However, the determination of TNF in serum and pleural effusion is not reported much at home and abroad, for which we conducted a discussion, the concept of our results reported below. Subjects and methods First, the object: 34 cases of cancerous pleural effusion (male 28, female 6), the average age of 42.5 years (18 to 77 years), are lung cancer patients. Tuberculous pleural effusion in 31 cases (20 men and 11 women), mean age 36 years (17 to 61 years), all cases were confirmed by X-ray, CT, bacteriological, biopsy confirmed. All
