肺癌与结核是渗出性胸膜炎的常见病因,本文通过对30例恶性胸水中中分子物质测定以及血浆、胸水MMS比值测定以鉴别胸水的性质,结果表明该法有一定临床意义。现报告如下: 1 材料与方法 1.1 结核组:结核性胸膜炎21例,男16例,女5例,年龄17～72岁,平均43.3±16.0岁。在抗痨治疗前后做血浆、胸水的MMS测定。 1.2 健康组:系本院职工非吸烟者,既往无心肺疾患。 Lung cancer and tuberculosis are common causes of exudative pleurisy. In this paper, the determination of molecular substances in malignant pleural effusion and the MMS ratio of plasma and pleural fluid were used to identify the nature of pleural effusion. The results showed that this method has certain clinical significance. The report is as follows: 1 Materials and Methods 1.1 Tuberculosis group: tuberculous pleurisy in 21 cases, 16 males and 5 females, aged 17 to 72 years, mean 43.3±16.0 years old. MMS determination of plasma and pleural fluid was performed before and after the anti-spasm treatment. 1.2 Health Group: It is a non-smoker from the staff of the hospital and has no previous cardiopulmonary disease.
