Antioxidant effect of butylated hydroxytoluene on ferric nitrilotriacetate induced renal hyper proliferation and injury in rats
2013
Ansar, S.
This study was designed to investigate the effect of butylated hydroxy toluene (BHT), a phenolic antioxidant used in foods, cosmetics and pharmaceutical products, on Fe-NTA-induced nephrotoxicity in rats. Fe-NTA (alone) treatment enhances ornithine decarboxylase activity to 5.3-fold, and [3H] thymidine incorporation in DNA to 3.5-fold compared with the corresponding saline treated control. The enhanced ornithine decarboxylase activity and DNA synthesis showed a reduction to 2.12–2.15-fold respectively at a higher dose of 2mg BHT/day/animal, compared with the Fe-NTA treated group. Fe-NTA treatment also enhanced the renal microsomal lipid peroxidation to 2.0-fold and decreased the activities of glutathione and antioxidant enzymes to a range of 2.2–2.5-fold in kidney. These changes were reversed significantly in animals receiving a pretreatment of BHT. Present data suggests that BHT can prevent the toxic effects of Fe-NTA and can serve as a potent chemopreventive agent to suppress oxidant-induced tissue injury and nephrotoxicity in rats.
