近年国内已有测定体液β_2-微球蛋白(β_1-m)来判定多种内科疾病,但脑脊液β_2-m测定用于结脑诊断,尚未见报道。作者对确诊为结脑的30例,取其住院后首次脑脊液,采用放射免疫方法,测定β_2-m,试用于结脑的诊断,初步认为具有一定价值。结果与诊断:对照组30例(除外中枢神经系统疾患)测定脑脊液β_2-m值为0 In recent years, there have been determination of body fluid β_2-microglobulin (β_1-m) to determine a variety of medical diseases, but cerebrospinal fluid β_2-m determination for the diagnosis of tuberculosis has not been reported. The author of the diagnosis of tuberculous meningitis in 30 cases, taking the first post-hospital cerebrospinal fluid, using radioimmunoassay, determination of β_2-m, for the diagnosis of tuberculosis, initially that has a certain value. RESULTS AND DIAGNOSIS: The β_2-m value of cerebrospinal fluid in 30 patients (excluding central nervous system disorders) in the control group was 0
