β-淀粉样肽对海马 CA1 区神经元的 短暂性外向 K+电流的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 1998
目的: 为了在离子通道水平探讨β-淀粉样肽( β-AP)在 Alzheimer 病中的作用。方法: 用 7～ 21 d 大鼠,以链霉蛋 白酶 E 酶解加吸管吹打法制备海马 CA1区神经元; 利用全细胞膜片钳技术, 观察了β-AP25～ 35对急性分离海马 CA1 区锥体细 胞的短暂性 K+电流的影响。结果: β-AP25～ 35对短暂性 K+电流有明显抑制作用, 且呈明显浓度依赖性、时间依赖性和部分电 压依赖性。结论: β-AP 对 K+通道的影响在 Alzheimer 病的发生机制中具有重要作用 ...

飞秒激光辅助猴眼角膜基质透镜移植观察

Zhongshan Daxue xuebao. Yixue kexue ban, 2015
摘 要: 【目的】 评估飞秒激光辅助猴眼角膜基质透镜移植术后透镜生物相容性,观察猴眼表参数及泪液因子表达的变化?【方法】 3只健康青年恒河猴,麻醉后行双眼全飞秒激光角膜基质透镜取出术,左右眼分别为一组,右眼植入同种异体角膜基质透镜,左眼植入自体右眼取出的角膜基质透镜?术后1周?1月?3月?5月?6月观察眼表炎症反应?中央角膜厚度?屈光状态及角膜地形图变化,同时对术前?术后1周?1月?3月多个时间点猴眼泪液进行采集并进行多因子检测?【结果】 术后两组透镜均透明,未见排斥反应 ...
