電針對SAMP8小鼠海馬突觸功能影響的研究

電針對SAMP8小鼠海馬突觸功能影響的研究摘要：本研究旨在探究電針對SAMP8小鼠海馬突觸功能的影響，進一步深入探究電針對阿爾茨海默癥相關海馬損傷的治療作用。選取6個月齡的SAMP8小鼠40只，隨機分為電針組和模擬組，電針組采用電針治療，模擬組采用同樣操作，但不接通電流。通過行為學測試、電生理檢測、熒光染色法檢測等手段評估電針治療對SAMP8小鼠海馬突觸功能的影響。實驗結果顯示，電針治療能夠顯著改善SAMP8小鼠的學習記憶能力和空間識別能力，減緩海馬形態(tài)結構改變，促進海馬突觸傳遞功能的恢復，同時增強突觸可塑性，說明電針對阿爾茨海默癥相關海馬損傷具有很好的治療作用，為SAMP8小鼠的臨床治療提供了新思路和方法。
