肺结核、肺肿瘤及肺部非特异性炎症是临床常见的三大类肺部疾病,这些疾病的发病机理不同,免疫反应状态不同,因结核菌素反应导致巨噬细胞含量的变化在不同疾病可能存在差异。本试验观察注射结核菌素前后,三种疾病病人痰巨噬细胞数量变化及差别。 我们对150例患不同肺疾病的病人痰细胞成分进行了分析,痰中主要细胞成分是嗜中性粒细胞(80～90％),而巨噬细胞(1～10％)和淋巴细胞(1～5％)数量相对要小的多,嗜酸细胞和组织细胞数量不多或罕见,痰细胞成分在数量上的昼夜波动不重要也不可 Tuberculosis, lung cancer and lung non-specific inflammation are three common clinical lung disease, the pathogenesis of these diseases is different, different immune response due to tuberculin reaction leads to changes in macrophage content in different diseases may exist difference. This test observed before and after injection of tuberculin, sputum macrophages in patients with three disease changes in the number and differences. We analyzed the sputum cell components of 150 patients with different lung diseases, the main cell components in sputum were neutrophils (80-90%), while macrophages (1-10%) and lymphocytes ~ 5%) The number is relatively smaller, the number of eosinophils and tissue cells is small or rare, the number of diurnal fluctuations in the number of sputum cell components is not important nor
