AKR mice of which more than 90% die of lymphatic thymus leukaemia, had their mean survival time increased by weekly intraperitoneal inoculation of either of the two polycations DEAE-dextran and polybrene. Administration of the neutral dextran had no effect, whereas the polyanion dextran sulphate accelerated leukaemia development.Adult BALB/c mice infected with Rauscher leukaemia virus and treated from the time of palpable spleen enlargement, showed a life prolonging effect of the polycations DEAE/dextran and polybrene, and of neutral dextran. BALB/c mice treated from the time of leukaemia infection, however, showed a life prolonging effect with polyanion dextran sulphate and also of neutral dextran.
超过90%的AKR小鼠死于胸腺淋巴细胞白血病,通过每周腹腔注射两种聚阳离子(二乙氨基乙基葡聚糖和聚凝胺)中的任何一种,其平均存活时间得以延长。给予中性葡聚糖没有效果,而聚阴离子硫酸葡聚糖加速了白血病的发展。感染劳舍尔白血病病毒的成年BALB/c小鼠,从脾脏可触及肿大时开始治疗,结果显示聚阳离子二乙氨基乙基葡聚糖/葡聚糖和聚凝胺以及中性葡聚糖具有延长寿命的作用。然而,从白血病感染时开始治疗的BALB/c小鼠,聚阴离子硫酸葡聚糖以及中性葡聚糖均显示出延长寿命的作用。
