Objective To study the changes of the amplitude of ion channels currents in developing hippocampal neurons.Methods Using whole-cell patch-clamp techniques in cultured hippocampal neurons whose cultured day were 6 d and 16 d,respectively,changes of the amplitude of ion channels currents in developing hippocampal neurons were explored.Results Compared with the hippocampal neuron whose cultured day was 6 d,there were no statistical differences of the amplitude of voltage dependent sodium currents of hippocampal neuron whose cultured day was 16 d.The amplitude of voltage dependent potassium currents of hippocampal neuron whose cultured day was 16 d were significantly increased(P

Objective To study the changes of N-methyl-D-aspartate(NMDA)-receptor-channels current in developing hippocampal neurones during hypoxia and effect of adenosine intervention.Methods Whole-cell patch-clamp techniques cultured hippocampal neurons whose cultured day were 6 days and 16 days respectively,the amplitude of the NMDA-receptor-channels currents of hippocampal neuron were determined.And the effect of hypoxia on the NMDA-receptor-channels current,and adenosine regulatory mechanisms in cultured hippocampal neurons were explored.Results During hypoxia,compared with control group,the amplitude of the NMDA-receptorchannels currents of hippocampal neuron whose cultured day was 6 days were significantly increased(P
