【摘要】 利用血吸虫卵抗原中的有效物质的耐热特性,将热处理超声干卵挑入载玻片上或凹玻片凹孔内水滴中,然后直接加温使之干涸,制成了环卵沉淀试验(COPT)的抗原片。应用此“抗原片”检测粪检血吸虫卵阳性患者104例,COPT阳性率为96.15％;检测正常成人和15岁以下儿童63例,全部阴性。更多还原

【Abstract】 As the effective components of schistosome egg antigen were heat-stable, the "antigen slide" on which the heated and ultrasonicated ova suspended in distilled water were dried by heating was used for COPT. Sera from 104 patients passing schistosome eggs gave a COPT positivity rate of 96.2%. The "antigen slide" COPT is recommended because its manipulation was faster and simpler than that of routine COPT, and positive slides could be kept for a comparatively longer period of time.更多还原
