Effects of Erythromycin on Voltage-dependent Potassium Current in Hippocampal Neurons of Mice / 中国药房

ABSTRACT

OBJECTIVE:To study the effect of erythromycin on the voltage-dependent K~+ current in hippocampal neurons of mice.METHODS:Isolation of mice's hippocammal neurons cells and whole-cell patch-clamp techniques were applied to study the change of voltage-dependent K~+ current of hippocampal neurons and the current-voltage curves in mice before and after treatment with erythromycin.RESULTS:Erythromycin inhibited the voltage-dependent K~+ current of mice's hippocampal neurons,and it down-regulated the peak current from(810.67?250.86)pA to(529.96?171.83)pA(P
