Increase of Lipid Hydroperoxides in the Rat Liver and Kidney after Administering Ferric Nitrilotriacetate

抄録

  Two hours after an intraperitoneal injection of ferric nitrilotriacetate to rats at a dose of 15 mg of Fe/kg of body weight, the level of lipid hydroperoxides, which was determined by a specific method involving chemical conversion into 1-naphthyldiphenylphosphine oxide and HPLC, had increased significantly in the liver (from 190.1±58.8 of the control to 467.1±175.8 pmol/mg of protein) and kidney (from 181.8±52.3 of the control to 405.9±22.7 pmol/mg of protein). These results demonstrate that oxidative stress was transiently increased by an iron overload in these tissues.
