Abstract
A marked difference in sensitivity to the direct effect of the polysaccharide levan on tumour cells was observed between two variants of malignancy of Lewis lung carcinoma: cells of the more malignant variant (3LL-M) were much more sensitive to the drug than those of the less malignant tumour (3LL). A gradual decrease in tumorigenicity following preincubation with increasing levan concentrations was observed with both variants, but statistically significant inhibition was observed at lower levan concentrations with 3LL-M than with 3LL.
摘要
在Lewis肺癌的两种恶性变体之间观察到对多糖果聚糖对肿瘤细胞直接作用的敏感性存在显著差异：恶性程度较高的变体（3LL-M）的细胞对该药物的敏感性远高于恶性程度较低的肿瘤（3LL）的细胞。两种变体在与浓度不断增加的果聚糖预孵育后致瘤性均逐渐降低，但与3LL相比，3LL-M在较低果聚糖浓度下观察到具有统计学意义的抑制作用。
