Popis: cis -Dichlorodiamminoplatinum-II ( cis -DDP) has been widely used as an anticancer chemotherapeutic agent. The mutagenicity of ( cis -DDP) was investigated in vitro and in vivo using sister-chromatid exchange analysis and the analysis of chromosomal aberrations. Parallel human lymphocyte cultures were incubated with and without the addition of BrdU at 4 concentrations of cis -DDP. Significant increases in SCE rate were observed at 0.25 μg/ml and higher, showing a clear dose-response relation between SCE rate and cis -DDP concentration. A significant increase in chromosome breakage and tetraradial figures was observed in BrdU free cultures treated with cis -DDP again showing a dose dependency. Analysis of the distribution of cells in the first, second and third division in cis -DDP treated cultures demonstrated the depressing effect of the drug on mitotic activity. In vivo analysis of SCE and chromosome aberrations in mouse showed that 13.85 mg/kg i.p. of cis -DDP produces significant increases in the rate of SCE and chromosome aberrations in bone-marrow cells.
