Commercial mixtures of polychlorinated biphenyls (PCBs, Aroclor 1016, 1254, and 1260) differing in their degree of chlorination and their accumulation in the brain were employed along with a peripheral monoamine oxidase inhibitor, debrisoquin sulfate (Declinax, DS) to determine whether the rise in

The effect of a single oral gavage with a mixture of Aroclors 1254 and 1260 on 24-h production of urinary homovanillic acid was determined in the laboratory rat. Adult male Wistar-derived rats were exposed to a single dose of corn oil, either alone or containing equal amounts of Aroclors 1254 and

Exposure to organic solvents frequently causes functional impairment of the central nervous system (CNS). One method to examine the effects of solvent exposure on visual function is flash-evoked potentials (FEPs). Greater knowledge of the role of various neurotransmitters in generating FEP peaks

OBJECTIVE
To investigate the effects of pyrethroids on nigrostriatal dopaminergic pathways in male rats and its mechanism.
METHODS
Different doses of permethrin (PM, 200, 400 mg/kg) and deltamethrin (DM, 6.25, 12.50 mg/kg) in corn oil were administered to rats by gavage once daily for ten days, then

Young adult male CD-1 mice were treated orally twice weekly for three weeks with 0, 0.05, 0.15 or 0.65 mg/kg of aflatoxin B1 (AFB1) in corn oil. Two days after the last dose, the mice were killed by decapitation and the concentrations of the brain catecholamines, norepinephrine (NE), and dopamine
