    Abstract:
    The clastogenic effect of the drug cis-diamminedichloroplatinum II (cisplatin, CDDP) was investigated in Wistar rat bone marrow cells. Male rats, 3 per treatment time, aged 4 months and weighing 250-350 g were injected intraperitoneally with 6.0 mg/kg CDDP solution, and the control group received isotonic saline. The animals were sacrificed 6, 12, 18, 24 and 48 h after the injection. The chromosome preparation was obtained from bone marrow cells. Chromatid and chromosome aberrations were investigated in 300 metaphases per animal. A significant increase in number of chromosome aberrations was observed from 6 to 24 h, the majority being of the break and gap type. After 48 h a progressive reduction was observed, without differences from the negative control. These data confirm the mutagenic effect of CDDP in rats demonstrated for mice bone marrow by micronuclei assay, for murine ovary cells and mice spermatocytes.
