Induction Of Apoptosis By Ferrite Stainless Steel In The Mouse Fibroblast L929 Cells

ObjectiveComing together the domestic and foreign achievement , we develop a same kind of product suiting for the clinical application , and further improve its construction and function which will promote an extensive application of magnetic attachment in the domestic dental realm. The magnetic materials is ferrite stainless steel which posses excellent mechanism and corrosion resistance . In the experiment , we investigate the biocompatibility of ferrite stainless steel which will be used in the new magnetic attachment by apoptosis - assay for the culture cells in vitro, in order to provide a biological basis for the clinical application of the magnetic attachment.Methods1. The experimental materials:The experimental materials are divided into : Tilite alloy , the ferrite stainless steel , Co - Cr alloy . The metal materials are made into some plates that diameter is 12mm and thickness is 0.2mm . After disinfected and sterilized , the materials are put into 24 bores culture plate . Then we use the RPMI -1640 culture liquids to prepare the extracting liquids of the materials and collect it every 48h.2. The experimental methods: 2.1. The induction of apoptosis:...
