作者报导应用离子交换萤光测定法对脑脊液的r—氨基丁酸(GABA)进行定量检测。136例确诊为各种神经系统疾病的患者作为检查对象,同时以19例非器质性神经或精神疾病的患者作为对照。本文根据测定的结果,讨论其临床意义。离子交换萤光测定法较其他方法敏感,但尚须改进脑脊液的收集及贮存方法,以免使其 The authors report the quantitative determination of r-aminobutyric acid (GABA) in cerebrospinal fluid using ion-exchange fluorometry. 136 patients were diagnosed as various neurological diseases as a test object, while 19 cases of non-organic neurological or mental illness as a control. This article based on the results of the test to discuss its clinical significance. Ion exchange fluorometry is more sensitive than other methods, but there is still a need to improve methods of collecting and storing cerebrospinal fluid
