摘要 目的研究艾灸对衰老模型大鼠海马区神经元中Bcl-2与Bax的影响,从细胞凋亡的角度探讨艾灸治疗衰老的部分作用机制。方法以D-半乳糖皮下注射造成的衰老模型大鼠为研究对象,艾灸神阙穴,每日1次,连续30d。以通道式水迷宫测试学习记忆能力的变化,评价艾灸对衰老的治疗效应;以免疫组化SP法检测海马神经元中Bcl-2和Bax表达。结果与模型组大鼠相比,艾灸组大鼠海马神经元中Bcl-2的阳性细胞数显著增加(P<0.05),而Bax的阳性细胞数显著降低(P<0.05)。结论艾灸能有效改善衰老可能是通过促进衰老大鼠海马神经元Bcl-2的表达,降低Bax的表达,进而抑制细胞的凋亡,减少神经元的丢失来实现的。
