title: Recovery of malondialdehyde in urine as a 2,4-dinitrophenylhydrazine derivative after exposure to chloroform or hydroquinone.
abstract: Malondialdehyde (MDA) excretion in urine as an index for toxicological effects of chloroform and hydroquinone was evaluated. In a first series of experiments three groups of rats were used: non-pretreated rats (group I), starved rats (group II) and starved plus phenobarbital pretreated rats (group III). Chloroform (0.15 or 0.30 ml/kg, p.o.) was given as a single dose. The MDA excretion was related to the pretreatment, and in group III to liver damage. In a second series of experiments control rats were administered hydroquinone (100 or 200 mg/kg, p.o.), which induced a dose-related MDA excretion. These data indicate that the MDA assay was a selective and accurate marker for toxicological effects induced by the tested compounds.
