循环M抗原(CMA)存在于曼氏血吸虫病人及感染动物的血清和尿中。本文报道了在感染仓鼠的循环免疫复合物和肾中检出曼氏血吸虫M抗原的结果。用1,000条曼氏血吸虫尾蚴感染的金色仓鼠10只,第45天解剖,从心脏采血,经门脉灌流冲虫,每鼠平均获虫达506±40条,取出肾脏。另对10只正常仓鼠亦同样取血和肾脏作为对照。抗原按Capron等(1968)及三氯醋酸(TCA)进行浸出制备。动物血清经分子
Circulating M antigen (CMA) is present in the serum and urine of Schistosoma mansoni patients and infected animals. This paper reports the results of the detection of M. mansoni M antigen in circulating immune complexes and kidneys infected with hamsters. Ten golden hamsters infected with 1,000 S. mansoni cercariae were dissected on the 45th day. Blood was collected from the heart and perfused by portal vein. On average, 506 ± 40 worms were harvested per mouse, and the kidneys were removed. Another 10 normal hamsters also take blood and kidney as a control. Antigens were prepared by leaching Capron et al. (1968) and trichloroacetic acid (TCA). Animal serum by molecules
