电针对SAMP8小鼠海马突触功能影响的研究

电针对SAMP8小鼠海马突触功能影响的研究摘要：本研究旨在探究电针对SAMP8小鼠海马突触功能的影响，进一步深入探究电针对阿尔茨海默症相关海马损伤的治疗作用。选取6个月龄的SAMP8小鼠40只，随机分为电针组和模拟组，电针组采用电针治疗，模拟组采用同样操作，但不接通电流。通过行为学测试、电生理检测、荧光染色法检测等手段评估电针治疗对SAMP8小鼠海马突触功能的影响。实验结果显示，电针治疗能够显著改善SAMP8小鼠的学习记忆能力和空间识别能力，减缓海马形态结构改变，促进海马突触传递功能的恢复，同时增强突触可塑性，说明电针对阿尔茨海默症相关海马损伤具有很好的治疗作用，为SAMP8小鼠的临床治疗提供了新思路和方法。
