title: Effect of classic convulsants on Cl- conductance of the GABA(A) receptor complex in membranes of cerebral cortex cells at the early stage of kindling.
abstract: Muscimol-stimulated Cl- conductance of synaptoneurosomes from the cerebral cortex of Wistar rats increased during the early stage of pharmacological kindling not inducing the seizure response in animals. Picrotoxin, bicuculline, and pentylenetetrazole potentiated inhibition of muscimol-dependent 36Cl- entry into synaptoneurosomes, which attested to increased sensitivity of the GABA(A) receptor/Cl- ionophore complex to classic convulsants.
