Abstract
We investigated the effects of pretreatment with tomato, garlic, and turmeric, alone and in combination, against 7,12-dimethylbenz[a]anthracene (DMBA)-induced genetic damage and oxidative stress in male Swiss mice. Measurement of the incidence of bone marrow micronuclei as well as the extent of lipid peroxidation and the status of the antioxidants reduced glutathione, glutathione peroxidase, and glutathione-S-transferase in the liver and erythrocytes were used as biomarkers of chemoprotection. In DMBA-treated animals, increased frequency of bone marrow micronuclei was accompanied by enhanced lipid peroxidation and antioxidant depletion. Pretreatment with tomato, garlic, and turmeric alone and a combination of these agents significantly reduced the frequencies of DMBA-induced bone marrow micronuclei as well as the extent of lipid peroxidation. These changes may be mediated by the antioxidant-enhancing effects of the dietary agents. The results of the present study suggest that a diet containing even low levels of different naturally occurring compounds is effective in exerting antigenotoxic effects by inhibiting DMBA-induced oxidative stress.
