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...

Introduction: Epilepsy is one of the most common neurologic disorders. Pharmacoresistance and adverse effects of current antiepileptic drugs (AEDs) necessitate development of new drugs and strategies for treatment of epilepsy. Omega 3-Polyunsaturated fatty acids (ω3-PUFAs) are safe nutritional supplements that recently considered for treatment of epilepsy. Anticonvulsant effect of docosahexa...

Schiff bases of N-methyl and N-acetyl isatin derivatives with different aryl amines have been synthesized and screened for anticonvulsant activities against maximal electroshock (MES) and subcutaneous metrazole (ScMet). N-methyl-5-bromo-3-(p-chlorophenylimino) isatin (2) exhibited anticonvulsant activity in MES and ScMet with LD50 > 600 mg kg(-1), showing better activity than the standard drugs...

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 ...

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...
