Effects of droperidol on the enhancement of persistent sodium currents induced by in vitro ischemia-like condition in isolated rat CA1 paramidal neurons / 中国临床药理学与治疗学

ABSTRACT

AIM: To study the effects of droperidol on the enhancement of persistent sodium currents induced by in vitro ischemia-like condition in isolated rat CA1 paramidal neurons. METHODS: Whole-cell patch-clamp recordings were made from enzymatically isolated rat CA1 hippocampal paramidal neurons. Ischemia was induced by oxygen and glucose deprivation. RESULTS: All of 3, 10 ,and 30 ?mol?L -1 of droperidol significantly inhibited the enhancement of persistent sodium currents induced by ischemia, but the different concentrations did not show significant difference. CONCLUSION: Droperidol in clinical concentration can inhibit the enhancement of persistent sodium current induced by ischemia.
