catalase/seizures

Experimental data indicate that acute hyperglycaemia can aggravate the consequences of epileptic seizures on the permeability of the blood-brain barrier (BBB). The purpose of this study was to examine the effects of chronic administration of alpha -tocopherol (vitamin E) and acute catalase

In the present study, we examined the neuroprotective effects of vitamin C in adult rats after pilocarpine-induced seizures. Vitamin C is an exogenous antioxidant that can be used in treatment of seizures. It can alter oxidative stress and damage neuronal induced by seizures. Its antioxidant

The ubiquitously expressed iron storage protein ferritin plays a central role in maintaining cellular iron homeostasis. Cytosolic ferritins are composed of heavy (H) and light (L) subunits that co-assemble into a hollow spherical shell with an internal cavity where iron is stored. The ferroxidase

Glutaric acidemia type I (GA-I) is an inherited metabolic disease characterized by accumulation of glutaric acid (GA) and seizures. The intrastriatal GA administration in rats has been used as an animal model to mimic seizures presented by glutaric acidemic patients. m-Trifluoromethyl diphenyl

The mechanism of epileptic seizure has not been identified clearly. Exercise can play a role of antioxidants against oxidative stress. In the present study, the neuroprotective effects of preconditioning exercise on epileptic seizure were investigated with focusing on antioxidants activity in the

The present study investigated the role of the glutathione system in seizures induced by diphenyl diselenide (PhSe)(2) (50 mg/kg) in rat pups (post natal day, 12-14). Reduced glutathione (GSH) (300 nmol/site; i.c.v.), administered 20 min before (PhSe)(2), abolished the appearance of seizures,

Enzymatic production of prostaglandins (PGs) from exogenous arachidonic acid was studied in brain microsomal fractions prepared from mice following pentylenetetrazol (PTZ)-induced convulsions. Prostaglandin E2 (PGE2) and prostaglandin F2 alpha (PGF2 alpha) measured either by radioimmunoassay or

This study was designed to verify the influence of MPEP (2-methyl-6-phenylethynyl pyridine hydrochloride), an antagonist of metabotropic glutamate receptor subtype 5 (mGluR5), in seizures and status epilepticus (SE) induced by pilocarpine in young rats. In order to investigate the protective effect

Epilepsy is one of the prevalent and major neurological disorders, and approximately one-third of the individuals with epilepsy experience seizures that do not respond well to available medications. We investigated whether oxysophocarpine (OSC) had anticonvulsant and neuroprotective property in the

The present study investigated the effects of isopulegol, a monoterpene alcohol, in PTZ-induced convulsions and verified possible involved mechanisms. Saline, isopulegol or diazepam were intraperitonealy injected 30 min before PTZ. The latency for development of convulsions and mortality, as well as

Convulsive seizures (CS) are deleterious consequences of acute cerebral insults and prejudicial events in epilepsy, affecting more than 50 million people worldwide. Molecular mechanisms of depression and epilepsy include an imbalance between excitatory and inhibitory neurotransmission provoking

There is increasing evidence advocating for the causal association between oxidative stress and different neurodegenerative disorders such as Alzheimer disease and epilepsy. We have previously shown that consumption of High-fat diet (HFD) induces oxidative stress, which results in hippocampal

Kainic acid (KA) administered systemically to rats produces seizures and brain damage. We measured an increase in reactive oxidant species (ROS) during KA-induced seizures in the extracellular fluid (ECF) of the piriform cortex, a brain region known to be subsequently damaged. Intracerebral

O2 toxicity of the central nervous system (CNS) may be a result of enhanced generation of reactive O2 species such as superoxide and H2O2 at high PO2. In this study, we measured H2O2 production in six regions of the rat brain before and after convulsions induced by hyperbaric hyperoxia (HBO). H2O2

It has been suggested that pilocarpine-induced seizures is mediated by increases in oxidative stress. Current researches have suggested that antioxidant compounds may afford some level of neuroprotection against the neurotoxicity of seizures in cellular level. The objective of the present study was
