In order to study the protection of β-carotene and vitamin C against the transformation of human lung fibroblasts cell induced by nickel sesquioxide, HLF cells were treated repeatedly by different concentrations of Ni2O3 in vitro.β-carotene (5.4mg/L) and vitamin C(1.8mg/L) were added into the media containing Ni2O3 (1.0mg/L) respectively. The identification of malignancy of the transformation of HLF cell was carried out by the tests of ConA and the growth on semisolid agar culture. The results showed that Ni2O3 could induce the malignant transformation of HLF cell. The transformed cell proliferated rapidly.
