title: Effect of single injection of pentylenetetrazole in a subconvulsive dose on Cl- conductance of the GABAA-receptor complex.
abstract: Muscimol-stimulated Cl(-)conductance in brain cortex synaptoneurosomes from Wistar rats decreased 15 min after single intraperitoneal injection of pentylenetetrazole in a subconvulsive dose. These changes reflected a decrease in functional activity of the GABA(A)-receptor/Cl(-)ionophore complex. Muscimol-stimulated Cl(-)conductance in synaptoneurosomes returned to normal 48 h after pentylenetetrazole administration.
