title: Clastogenicity of carbazole in mouse bone marrow cells in vivo.
abstract: Clastogenicity of carbazole was evaluated by employing mouse in vivo chromosomal aberration (CA) test. Carbazole administered intraperitoneally (i.p.) at the rate of 25, 50, 100, 150 and 200mg/kg b.w. to Swiss albino mice in vivo resulted in mitotic depression and induction of chromosomal aberrations. Dose related decrease in mitotic index (MI) and increase in the frequencies of chromosomal aberrations per cell (CAs/cell) and percent abnormal cells were recorded in bone marrow cells. However, statistically significant reduction in MI and increase in CAs/cell and percent abnormal cells were found only for the two higher doses. The results obtained indicate that carbazole or its metabolite, if any, is moderately clastogenic in the bone marrow cells of Swiss albino mice.
