| 摘 要： | 背景:无论是作为化疗药物载体还是作为肿瘤热疗介质,Fe3O4纳米粒子与肿瘤细胞微观结构的作用都有待于深入研究。目的:分析Fe3O4纳米粒子的细胞相容性,探讨其在骨肉瘤化疗中作为药物载体的应用和存在的问题。方法:参照GB/T16886.5-2003(医疗器械生物学评价第5部分:体外细胞毒性试验)的评价标准和要求,偶联十六烷基三甲基溴化铵、聚乙二醇、油酸钠Fe3O4纳米粒子胶体溶液,分别与大鼠原发骨肉瘤细胞和人成纤维细胞共培养的方式对其进行细胞毒性测试。结果及结论:偶联油酸钠Fe3O4纳米粒子细胞相容性良好,参照GB/T16886.5-2003标准属于安全范围。偶联十六烷基三甲基溴化铵Fe3O4纳米粒子细胞相容性差,不适宜作为化疗药物载体进入人体。偶联聚乙二醇Fe3O4纳米粒子有一定的细胞相容性,作为磁靶向热化疗载体还需研究。 |
