Male mice (25-30 g) were injected (ip) with either 0, 3.5 X 10(-6), 17.5 X 10(-6), or 26.25 X 10(-6) mol/kg of either tricyclohexyltin bromide (TCT) or triphenyltin acetate (TPhT) in a corn-oil vehicle. The mice were tested for maximal electroshock seizure (MES) at 0.5, 4, 24, and 96 h following
Lindane and endosulfan are chlorinated hydrocarbon pesticides that bind to the gamma-aminobutyric-acidA (GABAA) receptor ionophore complex. We have previously demonstrated development of a persistent predisposition to the seizure-inducing properties of these pesticides following repeated
Methylcyclopentadienyl manganese tricarbonyl (MMT) is an organic manganese-containing compound which is used as an additive in unleaded gasoline. One neurotoxic effect of MMT in mice is seizure activity. In this study, seizures were observed in mice treated with MMT in propylene glycol or corn oil.
The persistence of the kindled seizure state produced during exposure to 5 mg/kg/day lindane was compared to that produced in nonexposed subjects. Persistence was evaluated at intervals of 2 weeks and 2 months. Rats were kindled on corn oil alone or corn oil + lindane until each rat exhibited a
The ketogenic diet is a well-established, but relatively infrequently used, therapy for intractable seizures in children. Currently, the standard ketogenic diet is formulated using medium chain triglyceride (MCT) oil as its major caloric source. Cost, availability, and gastrointestinal side effects
The effects of toluene on the sensitivity to seizures induced by aminophylline were investigated. Mice were pretreated with an ip injection of corn oil or toluene (100-500 mg/kg) followed by a timed intravenous infusion of aminophylline at various time intervals to assess the seizure thresholds and
Toluene is one of the most widely used solvents. Electrophysiological studies indicated that this solvent directly affects various ligand gated ion channels including NMDA, GABA(A), nicotinic and glycine receptors. The effect of toluene on seizures induced by chemoconvulsants acting on these
The effects of three isomers (alpha, beta, gamma) of hexachlorocyclohexane on the acquisition and expression of kindled amygdaloid seizures were compared. Treatment with corn oil (vehicle) was compared with daily 5 mg/kg doses of the isomers for 15 days during kindling procedures. The results
There is an increasing body of evidence that the central nervous system is affected by cholestatic liver disorders. Cholestasis has been shown to result in a decreased seizure propensity which is believed to be mediated by an increased opioidergic tone and nitric oxide (NO) signaling pathway. In
This study investigated the effects of two supplementary dietary oils (fish oil and corn oil) as parts of isocaloric/isoproteic diets on growth, brain fatty acid composition, and behavior in rat pups with recurrent seizures. Recurrent seizures were induced by injecting rat pups with
Toluene, an industrial organic solvent, is voluntarily inhaled as drug of abuse. Toluene has been shown to inhibit the nicotinic acetylcholine receptors. Nicotinic receptors play an important role in brain development during brain growth spurt and early adolescence. The long-term effects of neonatal
Hexachlorobenzene (HCB), an environmental contaminant, has caused spontaneous convulsions in infants and neonate rats born and breast-fed from exposed mothers as well as in weanling rats exposed for many weeks. This study aimed to determine if HCB causes epileptiform convulsions in adult rats. For
Toxicology and carcinogenesis studies of technical-grade 2-mercaptobenzothiazole (96%-97% pure), a rubber accelerant and preservative, were conducted by administering the chemical by gavage in a corn oil vehicle to groups of F344/N rats and B6C3F1 mice of each sex for 16 days, 13 weeks, or 2 years.
Toxicology and carcinogenesis studies of n-butyl chloride (greater than 99.5% pure), a solvent as well as an alkylating agent, were conducted by exposing groups of F344/N rats and B6C3F1 mice to n-butyl chloride in corn oil by gavage for 14 days, 13 weeks, and 2 years. In the 14-day studies, no
Hexachloroethane is used in organic synthesis as a retarding agent in fermentation, as a camphor substitute in nitrocellulose, in pyrotechnics and smoke devices, in explosives, and as a solvent. In previous long-term gavage studies with B6C3F1 mice and Osbourne-Mendel rats (78 weeks of exposure
