BACKGROUND Ficus carica Linn. is reported to possess variety of activities, but its potential in CNS disorders is still to be explored. OBJECTIVE The present study was carried out to evaluate the CNS depressant activity of aqueous acetonic extract of Ficus carica Linn on different models in mice. MATERIALS AND METHODS The aerial parts of the plant Ficus carica L. were extracted with aqueous...

Teucrium polium (Labiatae) is a plant that widely grows in Iran. Some of species of Teucrium are used for a considerable range of actions in traditional medicine and T. polium has frequently been used as anticonvulsant. In this study, we investigated the protective effects of T. polium ethanolic aqueous extracts and related fractions on seizures induced by pentylenetetrazole (PTZ) and maximal e...

De novo loss-of-function mutations in the voltage-gated sodium channel (VGSC) SCN1A (encoding Nav1.1) are the main cause of Dravet syndrome (DS), a catastrophic early-life encephalopathy associated with prolonged and recurrent early-life febrile seizures (FSs), refractory afebrile epilepsy, cognitive and behavioral deficits, and a 15-20% mortality rate. SCN1A mutations also lead to genetic epil...

There is emerging evidence to support the efficacy of some antiepileptic drug (AED) combinations in refractory epilepsy. Definitive clinical studies are, however, difficult to perform. Experimental seizure models can be employed to identify potentially useful combinations for subsequent clinical evaluation. We have investigated the anticonvulsant effects of topiramate (TPM) in combination with ...

PURPOSE To determine the influence of indapamide on the protective action of numerous conventional and second-generation antiepileptic drugs (carbamazepine, lamotrigine, oxcarbazepine, phenobarbital, topiramate and valproate) in the mouse maximal electroshock seizure model. MATERIAL AND METHODS Electroconvulsions were evoked in Albino Swiss mice by a current (sine-wave, 0.2 s stimulus duratio...

PURPOSE. A new series of substituted quinoline-2(1H)-one and 1,2,4triazolo[4,3-a]-quinoline derivatives were designed and synthesized to meet the structural requirements essential for anticonvulsant properties. METHODS. 4-substituted-phenyl3,4-dihydro-2(1H)-quinolines, 5-substitutedphenyl-4,5-dihydro-1,2,4-triazolo[4,3a]quinolines and 5-substituted-phenyl-4,5-dihydro-1,2,4triazolo-[4,3-a]quinol...

The present study was designed to investigate the effects of fluoxetine (FXT), a selective serotonin reuptake inhibitor, on the effect of antiepileptic drugs (AEDs) in the maximal electroshock seizure (MES) model in mice. FXT at the doses of 25, 20 and 15 mg/kg significantly increased the electroconvulsive threshold. The antidepressant applied at the lower doses (10, 5 and 2.5 mg/kg) did not in...

A series of twenty new N-[(4-arylpiperazin-1-yl)-propyl]-2-aza-spiro[4.4]nonane- and [4.5]decane-1,3-dione derivatives were synthesized and their anticonvulsant activity was evaluated in maximal electroshock (MES) and sc pentertazole (sc PTZ) tests. Their neurotoxicity was examined as well. Although no antiseizure properties of the investigated compounds were found in the MES model, eight of th...

The anticonvulsant activity of topiramate combined with some convulsant agents (bicuculline--BIC, N-methyl-D-aspartate--NMDA, and kainic acid--KA), given at subconvulsive doses, was evaluated in the maximal electroshock (MES)-test in mice. BIC (1.5 mg/kg), KA (10 mg/kg) and NMDA (50 mg/kg) significantly decreased the anticonvulsant activity of topiramate raising its ED(50) from 76.2 mg/kg to 13...

Allopurinol, an inhibitor of xanthine oxidase, is indicated in the management of patients with elevated serum and urinary uric acid levels. It was also reported to be beneficial in patients with epilepsy when added to traditional antiepileptic drug. Here, we investigated the effect of allopurinol upon the electrical seizure threshold and its effect on the protective efficacy of common antiepile...
