摘要: 红细胞经胰蛋白酶处理后,海南株恶性疟原虫(Fcc-1/HN)裂殖子入侵明显抑制,经神经氮酸酶和麦胚凝集素(WGA)处理后裂殖子入侵受到部分抑制,而植物凝集素(PHA)处理对裂殖子入侵没有影响。经二酰胺(Diamide)、秋水仙碱和马来酰亚胺(NEM)处理的红细胞,裂殖子的入侵均受到显著抑制,以NEM的作用最强,当其浓度为2mM时,裂殖子的入侵完全被抑制。结果表明,应用化学与酶修饰的方法改变红细胞膜表面及膜骨架蛋白的结构和性质,恶性疟原虫裂殖子对红细胞的入侵作用出现变化。

Abstract: By treating chemically and enzymatically erythrocytic membrane to change its structure and properties, the recognition of merozoite to erythrocyte and the effect of erythrocyte skeleton protein on the invasion of P. falciparum (Fcc-l/HN) were studied. It was found that the invasion of merozoite into erythrocyte digested with trypsin was greatly decreased; merozoite invasion into the erythrocyte treated with neuraminidase or wheat germ agglutinin (WGA) was partially inhibited; erythrocytes treated with cross-linker diamide and depolymerizer colchicine, N-ethyl maleinimide (NEM) of skeleton protein had evident resistance to invasion; the invasion of merozoite into erythrocyte treated with 2.0mM of NEM was completely blocked.
