초록

Tempting to further understand the molecular mechanism of pharmacological action of ethanol, we investigated the acute effects of ethanol on the GABA-activated current (IGABA) of the cultured Sprague-Dawley rat hippocampal neurons in primary culture using the whole-cell patch-clamp technique. Patch-clamp recordings revealed that ethanol potentiated the Cl- current in a concentration-dependent manner(1-300mM) in the majority of the cell studied. This study demonstrates that ethanol can potentiate IGABA in mammalian central neurons.
