腺苷脱氨酶(ADA)广泛分布于淋巴组织,T细胞内的含量高于B 细胞。它参与体内的嘌呤代谢,催化腺苷、脱氧腺苷分别转化为肌苷和脱氧肌苷。在结核及其它以细胞免疫为主的疾病中,T 细胞受抗原刺激活化后ADA 活性增强。作者研究ADA 在结核性胸腔积液中的诊断意义。利用ADA 与次氯酸钠和酚在碱性溶液反应中释放氨,形成深蓝色的靛酚,检验92例不同病因所致的胸腔积液患者渗出液中ADA Adenosine deaminase (ADA) is widely distributed in the lymphoid tissue, T cell content higher than B cells. It is involved in the body’s purine metabolism, catalytic adenosine, deoxyadenosine into inosine and deoxyinosine. In tuberculosis and other cellular immune-based diseases, T-cell activation by antigen stimulation after ADA activity. The authors study the diagnostic significance of ADA in tuberculous pleural effusion. ADA with sodium hypochlorite and phenol in the alkaline solution reaction to release ammonia, the formation of dark blue indophenol, 92 cases of pleural effusion caused by different etiology ADA
