title: Suppression of mitomycin C-induced micronuclei in mouse bone marrow cells by post-treatment with vanillin.
abstract: Induction of micronuclei by mitomycin C (MMC) in mouse bone marrow cells was suppressed by post-treatment with vanillin, a component of vanilla essence flavour. Vanillin was given orally to mice 7.5 h after intraperitoneal injection of 2 mg/kg MMC. Post-treatment with vanillin at 500 mg/kg caused about 50% decrease in the frequency of micronucleated polychromatic erythrocytes (MN-PCEs). The effect of vanillin administration on the time-course of formation of MN-PCEs was also investigated. The suppressing effect was not due to a delay in the formation of MN-PCEs by the cytotoxic action of vanillin. Vanillin acts as an anticlastogenic factor in vivo.
