用环状免疫单扩散法,测定103例神经系统(无颅内出血)病人的脑脊髓液中的IgG和IgA,其中63例测定IgM。另测定9例非神经科手术病人的脑脊液作对照。结果表明,脑脊液中IgG与IgA升高,可能有助于神经系统炎性脱髓鞘病的诊断。脑脊液用聚丙烯酰胺浓缩后测定,可能提高IgA的检出率。文中还讨论了各种神经系统(尤以炎症性脱髓鞘)疾病脑 Cyclic immunodiffusion was used to determine IgG and IgA levels in cerebrospinal fluid in 103 patients with neurological disease (no intracranial hemorrhage), of which 63 were IgM. Another 9 cases of non-neurological surgery in patients with cerebrospinal fluid as a control. The results show that cerebrospinal fluid IgG and IgA increased, may contribute to the diagnosis of nervous system inflammatory demyelinating disease. CSF polyacrylamide concentration after the determination, may increase the detection rate of IgA. The article also discusses various nervous systems (especially inflammatory demyelination) disease brain
