多年来的研究证明血吸虫的表面膜有7 ??层,且最外层的性质与其各下层的不同。成虫表面膜的外层具有很多宿主特异性的抗原,其中一些可能系血吸虫所合成,另一些则系从宿主所获得。本文报导了血吸虫童虫和成虫外膜的一些物理、化学性质不同于宿主细胞,并发现对宿主无毒性的某些疏水化合物 Years of research has shown that schistosomes have a 7-layer surface membrane and the outermost layer is different from its underlying layer. The outer layer of the adult surface membrane has many host-specific antigens, some of which may be synthesized by schistosomes, while others are obtained from the host. This paper reports some of the physical and chemical properties of schistosomula and adult adventities that are different from the host cells and that certain hydrophobic compounds that are non-toxic to the host have been reported
