【摘要】 目的:研究电针对老年性痴呆(Alzheimer’s disease,AD)模型大鼠海马神经元线粒体酶活性的影响,从能量代谢的角度探讨电针治疗AD的部分作用机制。 方法:以D-半乳糖腹腔注射和AβⅠ-40海马注射诱导形成的AD模型大鼠作为研究对象,根据“补肾通督、醒脑益智”的治疗原则,电针“百会”、“涌泉”穴,每日一次,连续电针治疗20天。以通道式水迷宫行为学测试学习记忆能力的变化,评价电针对AD的治疗效应;以生化方法检测海马神经元线粒体琥珀酸脱氢酶、Na+-K+-ATP酶、Ca2+-Mg2+-ATP酶的活性。 结果:1、模针组大鼠平均逃避潜伏期(19.60+2.67s)较模型组(23.21+1.97s)明显缩短,统计学比较,有显著性差异(P<0.05);模针组大鼠进入盲端的错误次数(5.82±1.67次/3min)较模型组大鼠(6.87+1.80次/3min)明显减少,统计学比较,有显著性差异(P<0.05)。 2、模针组大鼠海马神经元线粒体琥珀酸脱氢酶活性(6.6951±0.7443 U/mgprot)较模型组(3.9093±0.6455 U/mgprot)明显提高,统计学比较,有极显著性差异(P<0.01);模针组大鼠海马神经元线粒体Na-K+-ATP酶活性(16.3886±1.6861 μmoLPi/mgprot/h)较模型组(11.1533±1.6578 μmoLPi/mgprot/h)明显提高,统计学比较,有显著性差异(P<0.05);模针组大鼠海马神经元线粒体Ca2+-Mg2+-ATP酶活性(17.1824±1.1054 μmoLPi/mgprot/h)较模型组

【Abstract】 Objective: To reveal the influence of electro-acupuncture therapy on the mitochondrial enzymatic activities of hippocampal neuron of animal model of Alzheimers’ disease (AD) and partly explore the mechanism of electro-acupuncture therapy on AD.Methods: The AD rats induced by D-glacatose and β-amyloid1-40 were acupunctured on "Baihui(Du20)" and "Yongquan(Kidney 1)" according to the therapeutic principle of "Tonifying kidney and dredging and activating Du meridian, Reviving brain and promoting intelligence". The treatment was once daily and lasted for 20 days. The changes of study and memory abilities before and after model-making and treatment of AD rats were observed to evaluate the curative effect. The activities of Succinic acid dehydrogenase(SDH), Na+-K+-ATPase, Ca2+-Mg2+-ATPase of mitonchodria of hippocampal neuron were detected after treatment.Results: 1、 Comparing with control group ( 23.21±1.97s) ,the average delitescence of electro-acupuncture group (19.60±2.67s) are obviously decreased (P<0.05 ); Comparing with control group (6.87±1.80 times/min) , improper times of electro-acupuncture group (5.82±1.67 times/min) are obviously decreased (P<0.05) ;2、 Comparing with control group (3.9093±0.6455 U/mgprot) ,the activities of SDH of electro-acupuncture group (6.6951 ± 0.7443
