초록

The effects of ethanol on 5-hydrosytryptamine(5-HT3) receptor-mediated ion current were evaluated in whole-cell patch-clamp recordings from NCB-20 neuroblastoma cells. The physiologic and pharmacologic properties of 5-HT-activated ion current in NCB-20 cells indicated that it was mediated by 5-HT3 receptors. Ethanol(25-100mM) potentiated 5-HT3 receptor-mediated current in a concentration-dependent manner.
