磺化异麦芽寡聚糖对人肝癌细胞株HCCLM3移植瘤生长的影响

目的：探讨磺化异麦芽寡聚糖（isomalto oligosaccharide sulfate, IMOS）对人肝癌细胞株HCCLM3移植瘤生长的影响。方法：用剂量递增腹腔给药的方法，监测IMOS对裸鼠体质量、肝肾功能及重要脏器组织病理学的影响。用活体荧光显微镜，每周动态评价0、30、60、90mg／（kg·d）IMOS治疗组裸鼠中HCCLM3肝癌移植瘤的生长情况。结果：在≤90mg／（kg·d）剂量下，IMOS对裸鼠无明显毒性，且能显著抑制肝癌生长。结论：IMOS是一种潜在的抗肝癌药物，值得进一步研究。

Effects of Isomalto Oligosaccharide Sulfate on HCCLM3 Xenograft Growth in Nude Mice

Objective：To explore the effects of isomalto oligosaccharide sulfate（lMOS） on HCCLM3 xenograft growth in nude mouse model. Methods： Body weights, hepatorenal functions and pathologic examinations of important organs of nude mice were assessed when IMOS was intraperitoneally injected using a dose-escalation strategy. HCCLM3 xenograft growths in 0, 30, 60 or 90 mg/（kg · d） IMOS treated mice were dynamically measured once a week by fluorescent stereomicroscope. Results： A robust inhibitory effect on HCCLM3 xenograft growth without obvious toxicities was observed when IMOS was administered at the dosage of no more than 90mg/（kg · d）. Conclusions： IMOS could be a potential anti-HCC agent and worth further studies in patients with HCC, especially disease at advanced stages.
