A Walde et al.
Acta pharmacologica et toxicologica, 53(1), 57-63 (1983-07-01)
The metabolism of p-tert.-butyltoluene (TBT) was studied in the rat and guinea pig. Both the methyl and the tert.-butyl group were oxidized to alcohol and carboxylic acid derivatives in these species. The major urinary metabolites in rats were p-tert.-butylbenzoic acid
S P Lund et al.
International journal of psychophysiology : official journal of the International Organization of Psychophysiology, 14(1), 41-48 (1993-01-01)
The use of evoked potentials to measure neurotoxicity was evaluated using 4-tert-butyltoluene (TBT) as a test compound. Male Wistar rats were habituated to the recordings of auditory- and flash-evoked potentials until the combined waveform of the evoked potentials reached a
K Ingebrigtsen et al.
Acta pharmacologica et toxicologica, 51(3), 203-208 (1982-09-01)
The distribution of [methyl-14C]p-tert.-butyltoluene was studied in the rat by use of whole-body autoradiography and liquid scintillation counting. The test substance was administered by inhalation. High concentration of radioactivity was seen in the CNS immediately after inhalation, from where it
