[Evaluation on cytotoxicity of gallium alloy]

Cytotoxicity is an important indicator to the biocompatibility of biomaterials. In this study, the cytotoxicity of Gallium alloy was evaluated by the method of cell relative growth rate in vitrousing L-929 mouse fibroblast. The cell relative growth rate of Gallium alloy was the absorbency ratio between the solution of Gallium alloy and negative control. The relative growth rates of Gallium aloy were converted into the scores of cytotoxicity. It was found from the results that Gallium alloy had no cytotoxicity.
