β_2-微球蛋白(β_2-M)是一种低分子蛋白质,正常人的β_2-M 合成释放的量相当恒定,关于CSF 中β_2-M 的测定报道极少,本文就我院测定CSF 中β_2-M100例作一介绍以供参考。测定方法本组病例采用放射免疫法测定CSF 中β_2-M 的含量,试剂盒由北京光华免疫试剂研究所提供,每位病人留取脑脊液0.1～1ml,放入冰箱贮存待测定。临床资料本组100例,分为:1.正常组:选择无神经系统疾病的10例患者,其中男6例,女4例,年龄11～37岁。2.肿瘤组:分为(1)颅内肿瘤:恶性肿瘤38例,男22例,女16例,年龄5～64岁。其中星形胶质瘤24例,髓
β_2-M is a kind of low-molecular-weight protein. The amount of β_2-M released by normal people is relatively constant. There are few reports on the determination of β_2-M in CSF. -M100 for an introduction for reference. Determination of this group of patients using radioimmunoassay determination of CSF β_2-M content, the kit provided by the Beijing Guanghua Institute of Immunology reagents, each patient with cerebrospinal fluid retention 0.1 ~ 1ml, stored in the refrigerator to be determined. Clinical data The group of 100 cases, divided into: 1. Normal group: 10 patients without nervous system diseases, including 6 males and 4 females, aged from 11 to 37 years. 2. Tumor group: Divided into (1) intracranial tumors: 38 cases of malignant tumors, 22 males and 16 females, aged 5 to 64 years. 24 cases of astrocytoma, myeloid
