Neonatal seizures can lead to later life epilepsy and neurobehavioral deficits, and there are no treatments to prevent these sequelae. We showed previously that hypoxia-induced seizures in a neonatal rat model induce rapid phosphorylation of serine-831 (S831) and Serine 845 (S845) sites of the AMPA receptor GluR1 subunit and later neuronal hyperexcitability and epilepsy, suggesting that seizure...

In the present study, the effect of essential oil of the root of Angelica archangelica Linn. was evaluated against electrically and chemically induced seizures. The seizures were induced in mice by maximal electroshock and pentylenetetrazol. The effect of essential oil of the root of Angelica archangelica on seizures was compared with standard anticonvulsant agents, phenytoin and diazepam. The ...

The effect of elevated baseline pulmonary vascular pressures on systemic and pulmonary vascular sequelae of prolonged seizures was studied in sheep. Five animals with seizures induced after baseline left atrial pressure elevations of 25 mm Hg were compared with animals treated with seizures alone. Seizure-induced elevations from baseline of systemic and pulmonary vascular pressures were identic...

Seizure-related emergencies caused by stimulants of abuse have been increasing. To better understand the nature of these drug-induced convulsions, we characterized the seizure patterns associated with high doses of cocaine, and the amphetamine analogs, methamphetamine, methylenedioxymethamphetamine (MDMA) and 4-methylaminorex. The features of the stimulant-induced seizures were distinct and inc...

Aim To determine the precise effects of post-traumatic seizure activity on hippocampal processes, we induced seizures at various intervals after traumatic brain injury (TBI) and analyzed plasticity at CA1 Schaffer collateral synapses. Material and Methods Rats were initially separated into two groups; one exposed solely to fluid percussion injury (FPI) at 2 Psi and the other only receiving ka...

To determine the anticonvulsant activity of the leaf extract of Croton zambesicus in mice and rats, and in order to verify the traditional use of the plant in the treatment of epilepsy. The pentyleneterazole (PTZ) and the maximal electroshock seizure (MES) models were used for assessing the anticonvulsant effects of the aqueous leaf extract in mice and rats. In the PTZ test, the leaf extract ...
