应用特异性单克隆抗体作DOT－ELISA和竞争ELISA检测65例脑囊虫病患者血清和脑脊液中游离循环Ag（FCAg）和循环免疫复合物抗原（CICAg）。血清FCAg阳性率分别为81．3％和81．5％（0．20～87．0μg／ml），CICAg阳性率为95.4％和92．3％（0.19～120.0μg／ml），脑脊液测定FCAg阳性单为78．5％和86.2％（0．32～25.0μg／ml），CICAg阳性率为90.8％和93.8％（0.19～46.4μg／ml）。结果表明检测总循环抗原（包括游离部分和复合物部分）有利于提高脑囊虫病的诊断。
Serum and cerebrospinal fluid (CSF) and circulating immunocomplex antigen (CICAg) were detected in 65 patients with cysticercosis using DOT-ELISA and competitive ELISA. The positive rates of FCAg in serum were 81.3% and 81.5% (0.20 ~ 87.0μg / ml), the positive rates of CICAg were 95.4% and 92.3% (0.19 ~ 120.0μg / ml) The positive rates were 78.5% and 86.2% (0.32 ~ 25.0μg / ml). The positive rates of CICAg were 90.8% and 93.8% (0.19 ~ 46.4μg / ml) respectively. The results show that the detection of total circulating antigen (including the free part and the complex part) is helpful to improve the diagnosis of cerebral cysticercosis.
