新型碳纤维增强复合材料的细胞毒性评价

Cytotoxicity of new carbon fiber reinforced carbon composites

目的体外评价新型碳纤维增强复合材料的细胞毒性。方法选用建系的 L929成纤维细胞进行体外细胞毒性实验,评价新型碳纤维增强复合材料对细胞增殖的影响。结果材料浸提液与 L929成纤维细胞作用后的细胞增殖度为第2d 104%,第4d 104%,第7d 77%,毒性判定为1级,有良好的细胞相容性。结论新型碳纤维增强复合材料未见明显的细胞毒性作用。

Objective To evaluate the general cytotoxicity of carbon fiber reinforced carbon composites. Methods L929 fibroblasts were used in this study to establish cell proliferation, Results The percentage of cell proliferation of extracts was high （2ds for 104%, 4ds for 104%, 7ds for 77%）, the toxicity was judged as 1 level with good cytocompatibility. Conclution Carbon fiber reinforced carbon composites have no obvious cytotoxicity.
