摘要: 本文对环卵沉淀试验(COP)的操作方法加以改进和简化。建立了聚氯乙烯薄膜抗原片环卵沉淀试验(PVC-COP),经过薄膜片的选择和定型、混悬虫卵抗原方法的确定、抗原片保存条件的比较以及各批制备抗原片稳定性的观察等研究,最终确定了“PVC薄膜抗原片”成品的制备标准和操作规程。 对82例粪检阳性血吸虫病患者血清的检测,获得阳性反应80例(97.6%);对361例无疫水接触史者的检测,出现假阳性反应6例(1.7%),两项结果与沿用的常规COP结果相近.对来自不同疫区(九江、孝感、常山、上海、武汉)694例血清与常规COP比较,两法之间的阳性率(t检验)和平均环沉率(X~2检验)均无显著性差异(P0.05)。证明PVC—COP除具有较理想的敏感性、特异性外,还有省工、省时、省物和便于邮递等优点,为基层开展应用环卵沉淀试验清查病人提供了一个新途径。

Abstract: This article compares the routine methods used in circumoval precipitin testa with PVC-COP using PVC membrane slide coated with egg antigen.By applying the above method to 82 parasitologically confirmed cases, we found that 80 of them showed positive reaction which means a positive rate of 97.6%. When applied to 361 healthy persons, the false positive rate was found to be 1.79%. By com-paring routine COP method with PVC-COP on 694 sera from different endemic areas, no statistical difference was found between the positive rate and the average circumoval precipitin rate (P0.05).On the whole PVC-COP is sensitive, specific and takes less time, material and labor, the slides can be easily carried or mailed, thus proved to be practical in field and epidemiological surveys.
