小檗碱诱导大鼠神经元毒性死亡的研究

Zhongshan Daxue xuebao. Yixue kexue ban, 1998
目的: 研究小檗碱( Ber)对原代培养的大鼠大脑皮质和小脑颗粒神经元的直接作用及 Ber 与间接胆红素的相互 作用。方法: 采用二乙酸荧光素( FDA)和 Hoechst 33258 DNA 染色法,观察神经元的存活率及形态学特征; 用琼脂糖凝胶电泳 和流式细胞仪分析 Ber 诱导神经元死亡的生化学特征。结果: Ber 呈剂量( 0～ 20μmol/L)依赖性地诱导原代培养的大鼠大脑 皮质和小脑颗粒神经元死亡。其死亡的机制呈现坏死的特征: 包括神经元胞体肿大、无明显核染色质浓缩、DNA 随机断裂而 ...

在无Mg2＋条件下完整神经元NMDA通道动力学的电压依赖性

Zhongshan Daxue xuebao. Yixue kexue ban, 1994
用膜片钳技术，在新生大鼠大脑皮层完整神经元膜上记录了电导为３５ｐＳ的Ｎ－甲基－Ｄ－门冬氨酶（ＮＭＤＡ）通道电流并在无Ｍｇ２＋条件下，详细分析了通道动力学的电压依赖性。ＮＭＤＡ通道对Ｎａ＋、Ｋ＋非选择性通透，对Ｃｌ－不通透，ＡＰＶ能阻断通道活动。通道的开放时间、ｂｕｒｓｔ时程及开放概率随超极化程度增大而减小。开放时间和ｂｕｒｓｔ时程的分布直方图均需双指教拟合，它们的慢时间成分也显示相似的电压依赖性。结果表明：完整神经元ＮＭＤＡ受体自身的通道动力学有明显的电压依赖性。
