title: Ferrihemoglobin and kidney lesions in rats produced by 4-aminophenol or 4-dimethylaminophenol.
abstract: 4-Dimethylaminophenol hydrochloride (DMAP), 20mg/kg i.v., was found to oxidize in rats as much as 50% of the hemoglobin to ferrihemoglobin but did not cause kidney lesions. 4-Aminophenol hydrochloride, 400 mg/kg i.v., oxidized only 25% of the hemoglobin and produced large tubular necroses. In highly toxic doses only, e.g., twice the LD50, DMAP also produced tubular necroses.
