【摘要】 目的探讨胸腔积液患者血清及胸腔积液中β2-微球蛋白(β2-MG)和唾液酸(SA)的变化及其临床意义。方法分别采用散射比浊法和酶法测定23例结核性胸腔积液患者、16例恶性胸腔积液患者血清及胸腔积液中β2-MG、SA的水平。结果结核组胸腔积液中β2-MG、SA水平显著高于恶性组,但两组患者血清β2-MG、SA水平无显著差异。结论胸水β2-MG、SA检测对结核性、恶性胸水有鉴别诊断价值。更多还原

【Abstract】 Objective To explore change and clinical significance of β₂-microglobuli （β2-MG） and saliva acid （SA） in pleural effusion and serum. Methods The serum and pleural effusion level ofβ2-MG and SA were measured in 23 cases of tuberculous pleural effusion and 16 cases of malignant pleural effusion. Results In pleural fluid and mean values ofβ2-Mg and Sa in tuberculous were significantly higher than in malignant（P<0.001）. In serum mean values there was no significant difference between the two groups. Conclusion Pleural fluidβ2-MG and SA levels may be used as an additional marker in the differential diagnosis of tuberculosis and malignant pleural effusion.更多还原
