摘要 目的:探讨电针对帕金森小鼠黑质致密部突触多巴胺转运体的影响。方法:24只C57BL/6J雄性小鼠,按照随机分组的原则分为空白组、空电组、模型组、电针组,每组6只。以腹腔注射(30mg/k)1-甲基-4苯基-1,2,3,6四氢吡啶诱导的帕金森小鼠作为研究对象,电针“合谷”、“太冲”穴,频率2-100HZ,电压2—4V,疏密波,每日1次,每次20min,7次为1疗程,共治疗3个疗程后,运用免疫组化检测黑质致密部多巴胺转运体表达。结果:电针组多巴胺转运蛋白免疫组化阳性细胞计数(24.67±13.01)较模型组(2.33±3.22)增加,P〈0.01;电针组积分光密度(26088.88±4498.05)也显著高于模型组(15248.27±4195.38),P〈0.05。结论:电针可促进帕金森小鼠黑质致密部多巴胺转运体的表达,从而发挥对帕金森小鼠突触多巴胺的调节作用。 Objective: To determine whether electroacupuncture (EA) treatment can regulate the expression of dopamine transporter (DAT) in Parkinson's disease (PD) mice substantia nigra compacta (SNC). Methods: Twentyfour male mice (C57BL/6J) were averagely and randomly divided into controlled group, controlled + EA group, model group and EA group. PD model mice were induced by i.p. 1 - methyl, 4 - phenyl - 1, 2, 3, 6 tetrahydropyridine. We take EA treatment with frequency from 2 to 100HZ, volt arrange from 2 to 4V, points on Hegu (LI4) and Taichong (LV3). The treatment was once daily. After 21 times treatments, we killed all mice and detected the expression of DAT by immunohistochemistry. Results: Compared to model group (2.33 ± 3.22), the DAT positive cells are more in EA group (24.67 ± 13.01) with significant statistical differences (P 〈 0.01). Conclusion: EA can increase the expression of DAT in PD mice SNC.
