F Gagnaire et al.
Journal of applied toxicology : JAT, 12(5), 335-342 (1992-10-01)
Motor and sensory conduction velocities (MCV and SCV), amplitude of the sensory action potential (ASAP) of the tail nerve and parameters of brainstem auditory evoked potentials (BAEP) were studied in male Sprague-Dawley rats after prolonged inhalation exposure to a commercial
I Linhart et al.
Journal of chromatography, 530(2), 283-294 (1990-09-14)
The metabolism of 1,4-diethenylbenzene in the rat was followed by gas chromatographic-mass spectrometric analysis of urine using three different derivatization procedures: (i) methylation-acetylation; (ii) methylation-trimethylsilylation; (iii) methylation followed by conversion into trimethylsilyloximes. Fifteen metabolites were found in the urine of

Journal of applied toxicology : JAT, 12(5), 343-350 (1992-10-01)
Male Sprague-Dawley rats were treated either with 1,2-diethylbenzene (1,2-DEB) or its putative active metabolite, 1,2-diacetylbenzene (1,2-DAB). Experimental rats and appropriate controls were examined electrophysiologically for brainstem auditory evoked potentials (BAEP). Oral administration of 1,2-DEB (75 or 100 mg kg-1 once

The commercial isomer mixture of diethylbenzene (DEB mixture), 1,2-diethylbenzene (1,2-DEB), 1,3-diethylbenzene (1,3-DEB) and 1,4-diethylbenzene (1,4-DEB) were administered orally to male Sprague-Dawley rats. The experimental rats and the appropriate controls were examined electrophysiologically for motor and sensory conduction velocities (MCV and
