摘要: 采用细胞灶法测定结晶型硫化镍对BALB/ c - 3T3 诱发细胞转化的活性,结果表明当硫化镍浓度≥0. 25μg/ cm2 时转化率增高( P > 0. 05) ,且有剂量反应关系。各剂量组转化灶细胞共6 份经软琼脂培养试验均获阳性结果,而对照细胞则为阴性,提示硫化镍诱发的转化细胞具有锚着不依赖性,即恶性特征。

Abstract: Focus system was used to assay the cell t ransforming activity of crystalline nickel sulfide (NiS) in BALB/ c - 3T3 cells. The result s indicated that at the concent rations equal to or above 0. 25μg/ cm2 , NiS induced increases in t ransformation f requency ( P < 0. 05) , in a concent ration2dependent manner. The transformed cells f rom 6 different foci all grew to colonies on soft agar ccultures while cont rol cells appeared negative. This result showed the anchorage2independence of the transformed cells from various foci which is one of the features of malignancy.

Key words: crystalline nickel sulfide, BALB/ c-3T3 cells, cell transformation, malignancy
