本文用抗猪囊虫尾蚴抗原的单克隆抗体（ＭｃＡｂ）酶免疫法检测脑囊虫患者血清和脑脊液（ＣＳＦ）中的循环抗原（ｃＡｇ）．１１０例血和８０例ＣＳＦ中ｃＡｇ的阳性率分别为７２．７％（８０／１１０）和８７．５％（７０／８０），与４５例其它寄生虫病和脑部疾病患者血清和脑脊液均无交叉反应．３０例健康人血清全部阴性．８０例脑囊虫患者同时测定血和ＣＳＦ中ｃＡｇ单项或两项阳性的总阳性率为９５．０％．因此认为测定ｃＡｇ可作为现症患者的诊断依据．
In this paper, anti-Cysticercus cellulosae antigen monoclonal antibody (McAb) enzyme immunoassay for the detection of cerebral cysticercosis serum and cerebrospinal fluid (CSF) in circulating antigen (cAg). The positive rates of cAg in 110 cases of blood and 80 cases of CSF were 72.7% (80/110) and 87.5% (70/80), respectively. The positive rates of cAg in serum and cerebrospinal fluid in 45 cases of other parasitic diseases and brain diseases No cross-reaction. Serum of 30 healthy people were all negative. The positive rate of cAg in both blood and CSF of 80 patients with cerebral cysticercosis was 95.0%. So that the determination of cAg can be used as a diagnosis of patients with disease.
