Anticonvulsant effect of cytoskeletal depolymerizing drugs in combination with potassium channel (KATP) opener and adenylate cyclase activator was evaluated in animal models of epilepsy. Seizures were induced in the animals by subjecting them to maximal electroshock (MES) or by injecting a chemical convulsant, pentylenetetrazole (PTZ). Moreover a correlation with the nerve growth factor (NGF) w...

Oxydemeton-methyl, an organophosphate insecticide and acaricide produced decrease in the exploratory behaviour and prolongation of barbitone sodium induced hypnosis in rats after intermittent aerosol spray inhalational exposure, for 1/2 hour daily for 7 consecutive days, compared to the saline control group. Further, ED50 +/- SEM value for haloperidol induced catalepsy, CD50 +/- SEM value for p...

When studying the role of the locus coeruleus (LC) in the regulation of seizure susceptibility in rats, we found that bilateral LC lesion significantly lowered the electroshock seizure threshold for the tonic extension of forelegs. The pattern of maximal electroshock seizure was not affected by LC lesion, although the recovery time was slightly prolonged. In the pentylenetetrazol (PTZ) seizure ...

A panchagavya Ayurvedic formulation containing E. officinalis, G. glabra, and cow's ghee was evaluated for its effect on pentobarbital-induced sleeping time, pentylenetetrazol-induced seizures, maximal electroshock-induced seizures, spontaneous motor activity, rota-rod performance (motor coordination) and antagonism to amphetamine in mice. The formulation (300, 500 mg/kg, po) produced a signifi...

Epilepsy is a chronic disorder of the brain affecting around 50 million people in the world. Up to 30% of epileptic patients do not respond to available drugs and medical therapies. In this paper, anticonvulsant screening of 10 synthesized new derivatives of 1, 4-dihydropyridine-3, 5-dicarboxamides was performed. Anticonvulsant activity was evaluated by intravenous and intraperitoneal pentylene...

In the present study, Solanum melongena Linn. (Brinjal; Solanaceae), was evaluated for its antiepileptic activity against experimental seizures. The roots ethanolic extract of Solanum melongena protected mice against tonic convulsion induced by maximal electroshock, Pentylenetetrazole and Picrotoxin. It was found that ethanolic extract up to a dose of 300 mg/kg p.o. decreased the duration of to...

Enzyme cyclooxygenase (COX) is reported to play a significant role in neurodegeneration and may play a significant role in the pathogenesis of epilepsy. Bicuculline (4 mg/kg; ip), picrotoxin (8 mg/kg; ip) and electroshock (60 mA for 0.2 sec) significantly induced convulsions in male Laka mice. COX-inhibitors viz. nimesulide (2.5 mg/kg; ip) and rofecoxib (2 mg/kg, ip) administered 45 minutes pri...
