- W2413305743 abstract "目的3-（4，5-二甲基噻唑-2）-2，5-二苯基四氮唑溴盐（MTT）法体外评价CPTi和Ti-6A1—4V牙科种植体材料对人脐静脉血管内皮细胞（HU）增殖的影响，并检测这两种材料在细胞培养液中的腐蚀情况。方法将HU（2×104／mL）接种于CPTi和Ti-6A1—4V金属表面，电镜观察细胞接种初期的形态，MTT法检测细胞接种后4h、1d、2d、3d、7d、10d和14d所测的OD值，X射线光电子能谱分析（XPS）法分析2种金属在细胞培养液浸泡前后的表面层组元。结果采用SPSS13．0软件分析，细胞接种后4h、1d、2d、3d、7d、10d和14d所测的OD值表明2种材料没有统计学差异（P〈0．05）；接种后6h电镜下可以观察到细胞在CPTi和Ti-6Al—4V表面的形态基本类似，没有明显的形态和数量差别出现；XPS结果显示2种合金表面都有不同厚度的钝化膜形成，CPTi表面的钝化膜要比Ti-6Al—4V的厚一些。结论CPTi和Ti-6Al—4V对HU的增殖没有影响，在培养基中也没有发生腐蚀。" @default.
