据报道血清中LZM和微量元素测定有助于癌性疾病的诊断,而胸水中微量元素测定尚未见报道。我们对44例胸腔积液患者胸水微量元素Cu、Zn及LZM含量进行检测。 材料和方法 一、临床资料: 21例癌性胸水中5例收集于本院门诊或住院病人,16例收集于湖北省肿瘤医院住院病人,并经细胞病理学、纤支镜等确立诊断。23例结核性胸水中18例收集 It has been reported that the determination of LZM and trace elements in serum contributes to the diagnosis of cancerous diseases, and the determination of trace elements in pleural fluid has not been reported. We detected the contents of Cu, Zn, and LZM in pleural fluid in 44 patients with pleural effusion. Materials and Methods First, clinical data: 21 cases of cancerous pleural effusion were collected in our hospital or inpatients, 16 cases were collected in Hubei Provincial Cancer Hospital inpatients, and were diagnosed by cytopathology, fiber bronchoscopy, etc. 23 cases of tuberculous pleural effusion collected in 18 cases
