Effect of systemic treatment with antibodies against glutamate on the seizure response of C57Bl/6 mice after pentylenetetrazole kindling.

We studied the effect of single intraperitoneal injection of antibodies against glutamate on acute generalized epileptiform activity induced by intravenous injection of pentylenetetrazole in kindled C57Bl/6 mice. We found that in animals at various stages of kindling, administration of antibodies against glutamate in a dose of 25 mg/kg 1.5 h before testing increases the threshold of clonic seizures and tonic phase of seizures with lethal outcome and latency of seizure development, i.e. produces an antiepileptic effect.
