The purpose of this study was to evaluate the influence of the glycine site antagonist of the NMDA receptor, MRZ 2/576 (8-chloro-4-hydroxy-1-oxo-1,2-dihydropyridazino[4,5-b]quinolin-5-oxide choline salt), on the anticonvulsive activity of carbamazepine, oxcarbazepine, diphenylhydantoin, phenobarbital and valproate against maximal electroshock (MES)-induced seizures and ethosuximide, valproate a...

Trimethylolpropane phosphate (TMPP), pentylenetetrazol (PTZ) and N-methyl-beta-carboline-3-carboxamide (FG-7142) were evaluated and compared for facilitation of electrical kindling in freely moving rats. Stimulating/recording electrodes were implanted in the left amygdala (LAD), right amygdala (RAD) and left bed nucleus (LBN) of the stria terminalis. TMPP (0.275 mg/kg), PTZ (20 mg/kg), FG-7142 ...

Eclampsia, defined as unexplained seizure in a woman with preeclampsia, is a life-threatening complication of pregnancy with unclear etiology. Magnesium sulfate (MgSO4) is the leading eclamptic seizure prophylactic, yet its mechanism of action remains unclear. Here, we hypothesized severe preeclampsia is a state of increased seizure susceptibility due to blood-brain barrier (BBB) disruption and...

AIM To investigate the effects and mechanism of succinic acid on pentylenetetrazol (PTZ) chemical kindling and amygdala electrical kindling in rats. METHODS PTZ chemical kindling and amygdala electrical kindling models were established in rats. The effects of succinic acid on the behavior and afterdischarge of kindled rats were observed. The mice were pretreated with succinic acid, 30 min lat...

The lung provides a portal of entry for drug delivery that could be used to administer anticonvulsant substances to prevent or abort seizures. Here, we demonstrate that intrapulmonary propofol hemisuccinate (PHS) rapidly confers seizure protection in various rodent chemoconvulsant models. Propofol is a powerful anticonvulsant substance at subanesthetic doses, but it is a viscous, water-immiscib...

Bu çalışmanın amacı, sıçanlarda pentilentetrazol (PTZ) ile oluşturulan nöbetlerde diazepamın antikonvulzif etkinliğinde nitrik oksit sentaz (NOS) ve beyin kaynaklı nörotrofik faktör (BDNF) üzerine etkisini araştırmaktır. Çalışmada 24 adet erkek Wistar Albino sıçan kullanılmıştır. Sıçanlar kontrol grubu, salin (1 mL kg-1) + PTZ, diazepam (0,5 mg PTZ (2 kg-1)+PTZ grubu olarak 4 gruba ayrılmıştır ...

creatine exerts beneficial effects on a variety of pathologies in which energy metabolism and oxidative stress play an etiological role. creatine supplements have shown beneficial effects on neurological disorders including parkinson's disease, huntington's disease, amyotrophic lateral sclerosis, alzheimer's disease and stroke. however, the potential benefits of creatine for pati...

This study aimed to examine whether celecoxib influences clonic seizure thresholds through modulation of nitric oxidergic (NO) pathway. The effect of celecoxib (1-5 mg per kg, p.o.) was investigated on clonic seizures induced by pentylenetetrazole (PTZ, 50 and 80 mg per kg, i.p.) in male Swiss mice. The interaction of celecoxib-induced effects with NO pathway was examined using a NO synthase (N...

The aim of this study was to model fluoxetine-induced increase in anxiety appearing in the initial phase of the treatment with this antidepressant drug. The effects of acute administration of fluoxetine given alone and co-administered with a subthreshold dose of pentetrazole (PTZ), a proconvulsant agent with well recognized anxiogenic properties, were examined in the open field test of neophobi...
