目的:测定肺结核、肺肿瘤及非特异性炎症患者注射结核菌素前后痰巨噬细胞的不同数量变化,由此提供一种新的鉴别诊断方法。方法:皮内注射结核菌素、收集注射前、后痰液,测定痰巨噬细胞在不同时间的数量变化。结果:肺结核病人在结核菌素试验后痰巨噬细胞明显增加,肺部肿瘤及非特异性炎症则无显著性变化。结论:肺部患者测定结核菌素前后痰巨噬细胞变化,可作为菌阴肺结核与肺部肿瘤及非特异性炎症鉴别诊断依据之一。
OBJECTIVE: To determine different numbers of sputum macrophages before and after tuberculin injection in patients with pulmonary tuberculosis, lung cancer and non-specific inflammation, and to provide a new differential diagnosis method. Methods: Intragastric injection of tuberculin, collected before and after the sputum, sputum macrophage volume changes at different times. Results: After tuberculin test, sputum macrophages were significantly increased in pulmonary tuberculosis patients. No significant changes were found in lung tumors and nonspecific inflammation. Conclusion: The change of sputum macrophages in patients with pulmonary tuberculosis before and after tuberculin can be used as one of the differential diagnosis bases of bacterio-negative pulmonary tuberculosis and lung tumor and nonspecific inflammation.
