摘　　要：本文对55例由于各种病因引起的胸腔积液进行了腺苷脱氨酶(ADA)活性测定,结果表明结核性胸液(77.56±25.60)及其他感染性胸液(119.60±102.24)显著高于癌性胸液(21.35±8.12)和其他胸液(27.44±11.93)。以45u/L为界限值,结核性胸液ADA活性增高可作为与癌性胸液鉴别的指标。非结核性脓胸、淋巴瘤等产生的胸液ADA值亦可升高,故鉴别时应予注意。The activity of adenosine deaminase (ADA) was determined in 55 patients with pleural effusion of vanious etiology. The results showed that the mean enzyme was significently higher in the tuberculous effusion (77.56±25.60) and other infective effusion (119.60±102.24) than those of carcinomatous effusion (21.35±8.12) and other effusion (27.44±11.93). When the enzyme value is more than 45u/L, it is considered as tuberculous effusion. This test is of value in the differential diagnosis of tuberculosis and carcinomatous pleural effusion. However, the empyema and lymphomatous effusion also contains high levels of ADA, thus the differential diagnosis of uberculosis should be carefully evaluated.
