摘　　要：采用两种不锈钢材料对磁性固位体进行外包裹,以达到防腐蚀目的。通过体外细胞毒性实验,微核实验,及不锈钢材料对小鼠L 92 9细胞凋亡影响的实验研究,结果表明磁性固位体外包裹材料仅具有极微弱的细胞毒性,对小鼠无致畸作用,引起较低的细胞凋亡率,可安全地做为磁性固位体的外包裹材料。The magnetic attachment was wrapped up with two kinds of stainless steel with corrosion resistant quality.We investigated the toxicity of the culture cells in vitro,micronucleus,the mouse L-929 cell apoptosis affected by the stainless steel.The rcsults show that the wrapping outside materials of magnetic attachment has pretty faint cell toxicity,doesn't lead to the aberrant mouse,causes very low cell apoptotic ratio,and is a piece of safe material.
