We studied the effects of desipramine, alprazolam, muscimol and dizocilpine (MK-801) (alone or associated with desipramine) in the forced swimming test in rats after long-lasting termination of chronic exposure to vehicle and pentylenetetrazol. Sensitisation with pentylenetetrazol was ineffective in changing immobility time in the forced swimming test compared to vehicle treatment; pentylenetet...

Sodium valproate and tomato extract have been studied in different experimental models of epilepsy individually. The aim of the present study was to evaluate the effect of lycopene on the antiepileptic effects of sodium valproate against pentylenetetrazol-induced kindling in mice. Swiss albino mice of either sex were randomly divided into 5 groups, with each group containing 8 mice. These group...

UNLABELLED The AIM was to study the effects of lamotrigine on bicuculline and pentylenetetrazol models of epilepsy. MATERIAL AND METHODS Mice divided in 8 groups (n = 6) were pretreated intraperitoneally 30 min before pentylenetetrazol (50 mg/kg) or bicuculline (1 mg/kg) with saline 0.1 ml/10 g body weight or lamotrigine 10 mg/kg, 15 mg/kg or 20 mg/kg, respectively. The seizure intensity and ...

The interaction of pentobarbitone sodium with three analeptics viz. micoren, pentylenetetrazol and methedrine was studied in mice. Micoren prolonged pentobarbitone sleeping time. pentylenetetrazol shortened the sleeping time. Methedrine also shortened the sleeping time, but clonic convulsions of mild to severe intensity were noticed 45-60 minutes after the drug injection.

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 stress which...

Previous research has shown that ethosuximide in high enough doses disrupts operant responding in pigeons. Whether or not these same doses protect against seizure activity in this species has not been determined. In the present study a system for scoring pentylenetetrazol-induced seizures in pigeons was developed and the effects of ethosuximide on such seizures were evaluated. Pentylenetetrazol...

Experiments were carried out in mice to assess the protection provided by thiopentone (Intraval, May and Baker) and propofol (Diprivan, I.C.I.) against epileptiform seizures induced by electroshock and pentylenetetrazol. Intraperitoneal administration of propofol 50 mg kg-1 and thiopentone 25 mg kg-1 produced similar peak behavioural effects of mild sedation and incoordination. However, at thes...
