Abstract
The present study was undertaken to evaluate the possible ameliorating effect of butylated hydroxyl toluene (BHT), associated with ferric nitrilotriacetate (Fe-NTA)-induced oxidative stress and liver injury in mice. The treatment of mice with Fe-NTA alone enhances ornithine decarboxylase activity to 4.6 folds, protein carbonyl formation increased up to 2.9 folds and DNA synthesis expressed in terms of [3H] thymidine incorporation increased to 3.2 folds, and antioxidants and antioxidant enzymes decreased to 1.8-2.5 folds, compared with the corresponding saline-treated controls. These changes were reversed significantly (p < 0.001) in animals receiving a pretreatment of BHT. Our data show that BHT can reciprocate the toxic effects of Fe-NTA and can serve as a potent chemopreventive agent.
