摘要:

【摘要】 目的:研究羟基磷灰石(HAP)纳米溶胶对皮肤鳞癌(A431)细胞增殖的抑制作用。方法:超声乳化法配制HAP纳米溶胶。用含浓度分别为400mg/L,200mg/L,100mg/L,50mg/L HAP纳米溶胶的培养液培养A431细胞,在培养的第1、2、3、4、5天,通过MTT法检测细胞增殖抑制率;倒置显微镜下观察细胞形态变化。以浓度为10µg/ml的5-氟尿嘧啶(5-Fu)在同样条件下作用于细胞为阳性对照组。结果:超声乳化法配制的HAP纳米溶胶呈均匀分散的针状;400mg/L、200mg/L和100mg/L溶胶组对A431细胞抑制率在第5天达到各组最大值,此时400mg/L溶胶组与阳性对照组的抑制率分别为(77.89±6.29)%和(77.46±8.26)%, 50mg/L溶胶组抑制率为(1.23±0.15)%;倒置显微镜下见50mg/L溶胶组细胞数目持续增加,聚集成簇,细胞呈现多角形或梭形,胞浆透亮,而100mg/L 和200mg/L溶胶组的细胞数目分别增加至第4天和第3天开始下降,400mg/L溶胶组和阳性对照组细胞数目持续减少,细胞体积缩小,漂浮细胞增多。结论: HAP纳米溶胶对A431细胞的增殖具有明显的抑制作用,且抑制作用存在时间-浓度依赖关系。

Abstract:

Abstract:Objective: To explore the inhibition of the nm-HAP-sol to the generation of Human Skin Squamous Cell Carcinoma Cell (A431 cell). Methods: Nm-HAP-sol was prepared by transonic- emulsification. A431 cells were cultured with DMEM and the corresponding concentration of nm-HAP-sol in the 400mg/L,200mg/L,100mg/L,50mg/L nm-HAP-sol groups. At the 1, 2, 3, 4, 5 days, calculating cell inhibition ratio by MTT colorimetric and observing the the change of cell morphosis by inverted microscope. A431 cells were cultured with DMEM and 10µg/ml 5-Fu in the positive control group. Result: The nm-HAP-sol present the dispersed and uniformity needle. A431cells inhibition ratio was maximizing at the 5 day in the 400mg/L nm-HAP-sol group, the 200mg/L nm-HAP-sol group and the 100mg/L nm-HAP-sol group, inhibition ratio of the 400mg/L nm-HAP-sol group, the positive control group and the 50mg/L nm-HAP-sol group was respectively (77.89±6.29)%, (77.46±8.26)% and (1.23±0.15)%. It was detected that the number of A431 cells were persistently increasing in the 50mg/L nm-HAP-sol groups while decreasing in the 400mg/L nm-HAP-sol group, the positive control group and abidingly increasing for 4 and 3 days then decreasing in the 100mg/L and 200mg/L nm-HAP-sol group by inverted microscope. Conclusion: The nm-HAP-sol has a very evident inhibition to the generation of A431 cells in a time and dose dependent way.
