L-929细胞的典型形态呈阴性。10%Zn和Zn-（0.2-1.4）Li合金提取物培养的细胞形态仍呈纺锤形，表明该浓缩物下提取物没有细胞毒性。当提取物的浓度达到40%时，大多数细胞仍粘附在培养板上。然而，提取物中出现了不规则圆形漂浮细胞，Zn-（0.5-0.8）Li合金中的分数高于其他材料，表明Zn-（0.5-0.8）Li合金中提取物的细胞毒性升高。当提取物的浓度达到100%时，在所有提取物中只能看到悬浮的圆形细胞，显示100%提取物的细胞毒性较高。

Exemplary morphology of L-929 cells in good state with spindle shape are shown in negative group. The morphology of cells cultured in 10% extracts of Zn and Zn-(0.2–1.4)Li alloys still exhibits a spindle shape, indicating the no cytotoxicity of extracts under this concentration. When concentration of extracts reaches 40%, the majority of the cells still adhere to the culture plate. However, floating cells in irregular circular appear in the extracts, and fractions of these cells in Zn-(0.5–0.8)Li alloys are higher than that of the other materials, indicating the rising cytotoxicity of the extracts in Zn-(0.5–0.8)Li alloys. When the concentration of extracts reaches 100%, only suspending circular cells can be observed in all the extracts, showing high cytotoxicity of 100% extracts.
