The influx of 36Cl- into cerebral cortical and cerebellar microsacs from ICR mice and Sprague-Dawley rats was studied in incubations lasting 3 s, 500 ms, or 21 ms. In the 3-s assay, 10-40 mM ethanol did not affect either basal or gamma-aminobutyric acid (GABA)-mediated Cl- flux, at any GABA concentration tested. Only at a concentration of 600 mM did ethanol potentiate Cl- flux in both mouse and rat preparations. Ethanol (20 mM) also did not affect the significant potentiation of GABA-mediated flux produced by 50 microM pentobarbital or 2 microM diazepam in ICR mouse microsacs. In 21- and 500-ms incubations (quench-flow method), 50 microM pentobarbital significantly potentiated GABA-mediated Cl- flux in rat cortical microsacs, but 10-50 mM ethanol did not. These studies suggest that some as yet unrecognized factor is essential for ethanol enhancement of GABA-mediated Cl- flux, as reported by others in brain homogenates and in tissue culture.
