Acute nephrotoxicity induced by N-(3,5-dichlorophenyl)-3-hydroxysuccinamic acid in Fischer 344 rats.

abstract：:Pregnant CD-1 mice were given 32 mg/kg of 3,4,3',4'-tetrachlorobiphenyl (TCB) or corn oil vehicle, by gavage, on days 10--16 of gestation. At 1 year of age, the offspring were tested for spontaneous motor activity; the mice were then killed and dopamine (DA) levels and specific DA receptor binding were measured in the...
