Normobaric supplemental oxygen can prolong seizures not caused by hyperbaric oxygen therapy. In addition, hyperbaric oxygen therapy can cause seizures. The mechanism of hyperbaric oxygen-induced seizures is unknown. We hypothesized that pretreatment with pyridoxine may delay the onset of hyperbaric oxygen-induced seizures, recognizing that pyridoxine is already an antidote for some epileptogeni...

Endocannabinoid signaling is considered to suppress excessive excitability of neural circuits and to protect the brain from seizures. However, the precise mechanisms of this effect are poorly understood. Here, we report that 2-arachidonoylglycerol (2-AG), one of the two major endocannabinoids, is crucial for suppressing seizures. We found that kainate-induced seizures in mice lacking the 2-AG s...

to determine the anticonvulsant activity of the leaf extract of croton zambesicus in mice and rats, and in order to verify the traditional use of the plant in the treatment of epilepsy. the pentyleneterazole (ptz) and the maximal electroshock seizure (mes) models were used for assessing the anticonvulsant effects of the aqueous leaf extract in mice and rats. in the ptz test, the leaf extract (1...

Warnings regarding fireworks displays as a possible seizure-producing stimulus have been around for several years, but there is a lack of well-documented cases. This case describes photic- and/or pattern-induced seizures that appeared to be triggered by July 4 fireworks. This 8-year-old girl with hemiplegic cerebral palsy and known seizure disorder because of perinatal right middle cerebral art...

Seizures in adult rats result in long-term deficits in learning and memory, as well as an enhanced susceptibility to further seizures. In contrast, fewer lasting changes have been found following seizures in rats younger than 20 days old. This age-dependency could be due to differing amounts of hippocampal neuronal damage produced by seizures at different ages. To determine if there is an early...

AIM The changes of seizure susceptibility of transgenic mice overexpressing GABA transporter-1 (GAT-1) were studied to clarify the possible role of GABAergic transmission in epileptogenesis. METHODS Seizures were induced by intraperitoneal administration of pentylenetetrazol (PTZ), picrotoxin (PIC), or kainic acid (KA) respectively. The anticonvulsant effect of ethyl nipecotate was tested by ...

BACKGROUND ATP sensitive potassium channels are widely distributed in central nervous system (CNS) and these channels could be the target in CNS disorders by their modulators. PURPOSE The present study was designed to investigate the anticonvulsant potential of glibenclamide on MES induced seizure and pentylenetetrazole induced seizure in mice. METHODS Seizures were induced in 7 months albi...

Previous studies in rat models of neurodegenerative disorders have shown disregulation of striatal synaptotagmin7 mRNA. Here we explored the expression of synaptotagmin7 mRNA in the brains of rats with seizures triggered by the glutamatergic agonist kainate (10 mg/kg) or by the muscarinic agonist pilocarpine (30 mg/kg) in LiCl (3 mEq/kg) pre-treated (24 h) rats, in a time-course experiment (30 ...

Seizures related to alcohol are a common finding, and are usually attributed to alcohol withdrawal, or to a neurotoxic effect of ethanol leading to seizures that are unrelated to acute alcohol consumption or withdrawal. However, there is also evidence for a third kind of alcohol-related seizure: alcohol-induced seizures. We describe a 36-year-old patient who, during the years from 1996-2006, wa...

Status epilepticus (SE) is a common neurological emergency for which new treatments are needed. In vitro studies suggest a novel approach to controlling seizures in SE: acute inhibition of estrogen synthesis in the brain. Here, we show in rats that systemic administration of an aromatase (estrogen synthase) inhibitor after seizure onset strongly suppresses both electrographic and behavioral sei...
