针刺对抑郁症模型大鼠海马区单胺类神经递质的影响

针刺对抑郁症模型大鼠海马区单胺类神经递质的影响 　【Abstract】Objective To observe how acupuncture affects the mechanism of depression model rats.Methods Using Open-Field method to randomly select 40 adult SD male rats into normal control, model group, drug treatment and acupuncture treatment group, 10 rats per group. Separation, long term unpredictability, medium stimulation techniques were applied to modify rats? behavior. Then using Open-Field method to reflect changes in depressed model rats? behavior between groups treated with acupuncture and control. And the concentration of monoamine neurotransmitters and their metabolites in hippocampus of rat brain were determined by HPLC-ECD. Results Compared with normal control, acupuncture treatment group’s behavior was not different （P＞0.05）on the 7th day after treatment. On the 21th day after treatment, acupuncture treatment group’s behavior was not different （P＞0.05）with drug treatment group, and was more different with model group（P＜0.01）. Compared with normal group on the 21th day of treatment, the concentration of serotonin and norepinephrine in hippocampus of acupuncture treatment group was not different （P＞0.05）, whereas was more different with model group （P＜0.05，P＜0.01）.Conclusion This experiment proved that acupuncture treatment could change the behavior abnormality of depressive model rats. The curative effects is comparable to flouxetine. The changes of the concentration of serotonin and norepinephrine in hippocampus are one of the mechanism. 　　【Key words】acupuncture treatment；depression；disease model；rat；behavior；5 hydroxytryptamine (5-HT);NE 　　自1984年，针灸开始介入抑郁症的治疗以来，取得了确切的临床疗效，但是对于针刺作用的过程和机制研究尚不深入。为了探讨针刺在抑郁症治疗中的应用规律，我们观察了针刺对抑郁症模型大鼠海马区内单胺类神经递质的影响，并与氟西汀（选择性5-羟色胺再摄取抑制剂）作对照。现将研究结果报告如下。
