| 摘 要： | 应用等电聚焦技术将日本血吸虫可溶性虫卵抗原（ＳＥＡ）分为２０个不同等电点（ｐＩ）的组分（等电点范围为１．８６—１１．４０），测定其各组分的体液与细胞免疫反应及体外诱发肉芽肿形成反应。结果表明等电点酸性区的组分（ｐＩ３．７８－５．５４）在日本血吸虫肉芽肿形成中可能起重要的作用；抗体，在感染的早期（５ｗｋ）也与肉芽肿的调节有关。

| Abstract: | The soluble egg antigen of Schistosoma japonicum was fractionated into 20 individual isoelectric point (pI) fractions with different pIs ranging from 1.86-11.40 by isoelectric focusing (IEF). The fractions were tested for humoral and cellular responses, as well as in vitro granuloma formations.The results indicated that the fractions in the acidic region(pI 3.78-5.54)may play an important role in granuloma elicitation in schistosomiasis japonica,and antibodies are also involved in the regulation of granuloma formation especially at the early stage (5 week postinfection). |
