PURPOSE To study the effects of noninvasive transcranial focal electrical stimulation (TFS) via tripolar concentric ring electrodes (TCRE) on the electrographic and behavioral activity from pentylenetetrazole (PTZ)-induced seizures in rats. METHODS The TCREs were attached to the rat scalp. PTZ was administered and, after the first myoclonic jerk was observed, TFS was applied to the TFS treate...

BACKGROUND The effects of electromagnetic waves (EMWs) on humans and their relationship with various disorders have been investigated. We aimed to investigate the effects of exposure to different frequencies of EMWs in various durations in a mouse epilepsy model induced by pentylenetetrazole (PTZ). MATERIAL AND METHODS A total of 180 4-week-old male mice weighing 25-30 g were used in this stu...

The effects of hypoxia on susceptibility to pentylenetetrazol (PTZ)-induced seizures were assessed in juvenile rats. Animals at postnatal (P) day 25 were exposed to hypobaric hypoxia (simulated altitude of 7000 m) for 8 h PTZ in a dose of 100 mg/kg was injected 1, 3 or 7 days later and latency, pattern and severity of seizures were registered. Mortality due to seizures was also evaluated. Two s...

Cysteinyl leukotrienes (CysLTs) have been implicated in seizures and kindling; however, the effect of CysLT receptor antagonists on seizure frequency in kindled animals and changes in CysLT receptor expression after pentylenetetrazol (PTZ)-induced kindling have not been investigated. In this study, we evaluated whether the CysLT1 inverse agonist montelukast, and a classical anticonvulsant, phen...

background and objective: copper is one of the main micronutrients of body which plays a key role as a cofactor in the function of metabolic enzymes. previous studies have shown that copper sulfate () inhibits long-term potentiation (ltp) in slices of hippocampal ca1 region. whereas ltp is involved in learning and epilepsy, it seems that copper effects on ltp could be associated with its effect...

Introduction: Ketoprofen is an NSAID and selective COX-1 inhibitor. In our previous study the role of flunixin meglumine, a nonselective COX inhibitor was studied on seizure and its anticonvulsant effects were confirmed. Therefore this research is performed to assess the role of a selective COX-1 inhibitor, ketoprofen in treatment of seizures induced by PTZ. Methods: In this research, male ...

Objective: At present, there are many antiepileptic drugs with a wide range of side effects on the human body. It was assumed that Zataria multiflora Boiss (Z. multiflora) with sedative, anti-spasmodic and anti-inflammatory activity may be effective in the treatment of epilepsy. The aim of the present study was to elucidate the effect of Z. multiflora hydroalcoholic extract and its fraction ext...

Objective(s): Febrile seizures (FS) are the most common type of convulsive events among children. Its prevalence has been estimated to be 2-5% in children between 3 months and 5 years old. Also, blood and CSF magnesium levels have been demonstrated to be reduced in children with FS. This study investigates the effect of MgSo4 pretreatment on the behaviors caused by hyperthermia (HT) and effect ...
