title: Alleviation of nickel-induced biochemical alterations by chelating agents.
abstract: The effect of 1,4,8,11-tetraazacyclotetradecane (Cyclam), triethylenetetramine (TETA), reduced glutathione (GSH), ethylenediamine tetraacetic acid (EDTA), cyclohexanediamine tetraacetic acid (CDTA), diethylene triamine pentaacetic acid (DTPA), and hydroxyethylenediamine triacetic acid (HEDTA) on the alleviation of nickel-induced biochemical and trace-metal alterations in serum, liver, and kidney of nickel-treated rats was studied. The lipophilic chelating agents Cyclam and TETA exhibited a higher order of effectiveness in alleviating nickel-induced alterations compared to EDTA, CDTA, DTPA, and HEDTA, the hydrophilic chelating agents. The higher efficacy of lipophilic agents may be due to their ability to bind to nickel present in extracellular fluid as well as in intracellular fluid, while the hydrophilic agents may bind only to nickel present in extracellular fluid. Our data also suggest that the efficacy of Cyclam to ameliorate nickel-induced alterations is exceptionally high.
