摘要
用四甲基偶氮唑盐比色法(MTT)及直接接触细胞培养法对不同配比的甲基丙烯酸羟乙酯(HENA)和甲基丙烯酸甲酯(MMA)共聚物PHEMA-MMA进行了细胞毒性试验,结果一致,都为0级。表明该聚合物同样具有良好的生物相容性。两种方法比较,我们认为,直接接触细胞培养法对于生物材料毒性评估而言,方法简单、结果直观、效率更高。
Both methods of MTT assay and direct contact cell culture are used to cytotoxici measurement of copolymer PHEMA-MMA which are different. The results show the cytotoxicity stage of all the materials is 0 and the copolymers have excellent biocompatibility. As we thought it is better to direct contact ceil culture will be simplify, directly and more effectiveness for bio-materials evaluation.
