摘要: 采用CaptureELISA方法检测日本血吸虫感染鼠血清中抗SEA循环免疫复合物(SEAIC)水平在吡喹酮治疗后的变化。结果表明,感染鼠血清SEAIC水平在吡喹酮治疗后逐周下降。至治疗后第5wk时,15只小鼠中13只治愈,小鼠的血清SEAIC水平已显著下降,吸光度从治疗前的0.358±0.074(0.22-0.46)降至0.165±0.049(0.10-0.23),有非常显著差异(P<0.01);至治疗后第7wk时,有10只小鼠的血清SEAIC水平已转为阴性(吸光度小于0.097),另3只小鼠也降至近阴性水平。而2只虽经治疗但未治愈的小鼠血清SEAIC水平无显著变化(P>0.05)。并且,感染后未予吡喹酮治疗的小鼠血清SEAIC,直至实验观察结束时仍维持在较高水平(0.266±0.076)。

Abstract: Employing Capture ELISA, we determined the level of the circulating soluble egg antigen-antibody complex (SEAIC) in sera from mice infected with Schistosoma japonicum for 7 weeks and then treated the infected mice with praziquantel (100 mg/kg body weight). It was noted that the serum SEAIC level in treated mice dropped gradually after treatment. There was a significant decrease in 13 out of 15 mice in serum SEAIC levels at five weeks after treatment, OD value dropped from O. 358±0. 074 to 0.165±0. 049 (P0. 01). The serum SEAIC level in 10 mice declined to disappear (OD0.097) by the 7th week after treatment.By contrast, no significant changes in serum SEAIC levels were found in the non-treated mice, the serum SEAIC level in the control group maintained moderately high (OD=0. 266±0. 076) till the end of the observation.
