| Abstract: |
| 本文对一个血吸虫病疫区中的831名居民同时用IHA、COP及粪检进行了检查。IHA滴度呈双峰型分布，波谷落于1：5。以此为界值的阳性率：粪检阳性者84.8%，粪检阴性者24.6%（非疫区居民1.2%）。COP呈偏态分布，以环沉率1~4%和≥5%为界值的阳性率：粪检阳性者15.2%和19.9%：粪检阴性者14.7%和53.4%，IHA及COP的阳性率及平均反应值与粪检阳性率是正相关，尤以10~19岁年龄组之IHA与粪检结果相关性为优（r=0.958和1.974）。 |

| The present study was undertaken in an endemic area of schistosomiasis japonicum 831 human sub-jects were examined simultaneously for antibodies with IHA and COP, and for the eggs with stool microscopy. The titres of IHA showed a doublepeak distribution, and the trough fell to titre of 1:5. Taking it as the positive boundary value:84.8% was stool positive; 24.6% stool negative (the titre of residents in non-endemic area was 1.2%). COP presented a skewed distribution, the COP rate of 1-4% and 25% was used as a positive boundary vulue respectively, 15.2%-19.9% was stool positive, 14.7% and 53.4% negative. A close correlation was observed between the positive rate and average reaction value of COP and IHA, especially in 19-20 age group, the result of IHA was strongly correlated with stool examination (r=0.958 and 0.975). |
