It is believed that some pitfalls in the treatment of epilepsy including serious side effects of medications and drug resistance may be resolved by natural compounds. Auraptene is a natural coumarin that is found in many plants, particularly citrus peel. We hypothesized that auraptene might have anticonvulsant properties. Kindling was induced by repeated intraperitoneal (IP) injections of penty...

background and objective: n-methyl-d-aspartate (nmda) antagonists such as piperidines are the most important antiepileptic drugs. considering the fact that piperidine derivatives such as phencyclidine (pcp) and its new derivative, 1-[1-(3-methoxyphenyl) (tetralyl)] piperidine (pcp1), have different potencies, the antiepileptic effects of mentioned drugs were investigated in the present study. ...

Monosynaptic and polysynaptic responses of CA3 pyramidal cells (PC) to stimulation of the dentate gyrus (DG) are normally blocked by glutamate receptor antagonists (GluRAs). However, after kindled seizures, GluRAs block the monosynaptic excitatory postsynaptic potential (EPSP) and isolate a monosynaptic inhibitory postsynaptic potential (IPSP), suggesting that mossy fibers release GABA. However...

Voltage-gated sodium channels (VGSCs) play a vital role in controlling neuronal excitability. Nav1.6 is the most abundantly expressed VGSCs subtype in the adult central nervous system and has been found to contribute to facilitate the hyperexcitability of neurons after electrical induction of status epilepticus (SE). To clarify the exact expression patterns of Nav1.6 during epileptogenesis, we ...

  Objective(s): Stress induces many homeostatic aberrations which are followed by lifelong allostatic responses. Epilepsy is developed or influenced by different environmental factors, i.e. prenatal stress which makes many contradictory developmental changes in seizure threshold and intensity. We investigated the potential seizure response of the rat offspring to prenatal stress; the stres...

Background Rodent kindling induced by pentylenetetrazole (PTZ) is an established model of epileptogenesis and antiepileptic drug (AED) testing. Recently, a Drosophila systems model has been described in which chronic PTZ causes a decreased climbing speed in adult males on 7 day. Some AEDs ameliorate development of this locomotor deficit. Time-series of microarray expression profiles of heads of...

Openers or activators of neuronal KCNQ2/Q3 potassium channels decrease neuronal excitability and may provide benefit in the treatment of disorders of neuronal excitability such as epilepsy. In the present study, we evaluate the effects of ICA-27243 [N-(6-chloro-pyridin-3-yl)-3,4-difluoro-benzamide], an orally bioavailable, potent, and selective KCNQ2/Q3 opener, in a broad range of rodent seizur...
