作者用一种混合凝集素测定法检查曼氏血吸虫毛蚴和人工培养的母包蚴的各种不同的外源凝集素和人血型抗体的表面决定族的存在。发现毛蚴具有外源凝集素Con A(刀豆素A)、抗—H_(eel)(鳗类血清凝集素)和抗-A_(Db)(扁豆种子提取物)以及人的抗-A抗体的表面受体。随着毛蚴转变为母包蚴,在包蚴表面不再发现抗-H_(eel)和人的抗-A受体,然而Con A和抗-A_(Db)决定族基本保持不变。人工培养的包蚴的抗-A_(Db)决定族的分
The authors used a mixed lectin assay to examine the presence of surface-determining groups of various lectin and human blood group antibodies against Schistosoma mansoni and artificially cultured metacercariae. The miracidia were found to have the effects of the lectins Con A (Con A), anti-H eel (Anguilla anguillarum) and anti-A Db (lentil seed extract), and human anti-A antibody Surface receptor. With the conversion of miracidia to metacercaria, anti-eel and human anti-A receptor were no longer found on the surface of ascosphere, however, the Con A and anti-A-Db determinants remained unchanged. Artificial culture of the larvae of anti-A_ (Db) determines the race points
