目的 比较研究小鼠经不同途径接种日本血吸虫(Schistosoma japonicum, Sj) 童虫原代细胞(primary juvenile worm cells, pJCs)后所诱导的免疫保护效果,寻找其合适的免疫途径.方法 将pJCs经皮下或静脉注射途径免疫昆明小鼠,间隔2w共免疫3次,末次免疫后第4w,与对照组同时经腹部皮肤感染尾蚴30±2尾/鼠,比较三组小鼠的肝脏虫卵数及虫卵肉芽肿的大小、成虫数、虫体大小.同时在第2、3次免疫前及攻击感染前1d,小鼠尾静脉采血,用ELISA法检测抗pJCs-IgG水平.结果 pJCs免疫小鼠后,与PBS对照组比,静脉免疫组的减虫率为48.53%、肝卵减少率为54.54%、虫体平均重量减少率为29.62%(P

In order to observe the influence of immunization route on the immune protective effects induced by primary juvenile worm cells（pJCs）,Kunming mice were inoculated intravenously or subcutaneously with pJCs from 12 day-old Schistosoma japonicum respectively.All mice were immunized three times at 2 weeks interval and were challenged each with 30±2 cercariae by abdominal skin penetration 4 weeks after the last booster.Six weeks of post-infection,mice were sacrificed by aether inhalation,and the numbers of worms and hepatic eggs were counted.Spec...
