摘要
目的 利用体外细胞培养技术评价三种复合亲水性材料的细胞毒性,为材料的临床应用作前期准备。方法 用材料浸提液同L-929成纤维细胞接触2、4、7天后用紫外分光光度仪测定光吸收度,以评价材料的细胞毒性。结果 三种材料的细胞毒性均为Ⅰ级。结论 三种材料对培养细胞显示未见明显的细胞毒性。
Objective To evaluate cytotoxicty of 3 hydrophilic composite materials and provide a sound scientific basis for clinic usage. Methods The in vitro cytoxicity of three hydrophilic composite materials was examined by cell relative growth rate assay. Results The cytotoxic score of three hydrophilic composite materials was class I . Conclusion The in vitro cytoxicity of this three materials was slight.
