ABSTRACT
Objective To detect micronuclei (MN) induced by nickel chloride (NiCl2) using a flow cytometry-based method, so as to study the mutagenecity of this chemical. Methods The micronucleated reticulocytes (MN-RET) in peripheral blood of NIH mice exposed to 0.75 mg/kg colchicines (COL), 40.0 mg/kg of cyclophosphamide (CP) and 5.0, 10.0 and 20.0 mg/kg of NiCl2 were detected by a flow cytometry-based method, in which anti-CD71-FITC and PI were used to stain cells and malaria-infected erythrocytes were employed as biological standards of micronuclei to optimize cytometry. Results Although COL or CP induced significant increase in the frequency of MN-RET in peripheral blood, MN formation in peripheral reticulocytes was not significantly affected by exposing to different concentration of NiCl2. Conclusion The results of flow cytometric analysis in the present paper do not support that NiCl2 exposure may induce significant MN-RET increase in peripheral blood in NIH mice.
