针刺足三里PET脑功能成像


□ 尹 岭等

  [摘 要]目的:探讨针刺足三里穴PET脑功能成像的实验方法,寻找针刺足三里脑功能变化的实验依据。方法:用PET对6例男性健康志愿者行针刺右侧足三里前后的18FDG-PET脑功能成像,用SPM软件处理脑内葡萄糖代谢率变化的实验数据,获得脑功能变化的可视性实验依据。结果:针刺右侧足三里穴引起视丘下部、尾状核头部、小脑、颞叶、中央后回、脑干的葡萄糖代谢增加。

  结论:针刺足三里穴可引起与内脏功能有关的皮质下植物神经中枢葡萄糖代谢增加,PET是研究针灸中枢机制的可行性方法之一。

  ABSTRACT Objective To probe into experimental methods for brain

functional imaging at acupuncture of Zusanli (ST 36) with PET so as to und erstand

the change of cerebral function.Methods Before and after acupuncture at

Zusanli (ST 36) on right side in 6 male healthy volunteers, PET was used for18FDG

-PET cerebral functional imaging and the data on cerebral glycometabolism was

obtained by usin gpositron emission tomography (PET), and the visual

experimental evidence by us ing statistical parametric mapping (SPM). Results

Acupuncture at Zusanli (ST 36) on the right side increased glycometabo lism in

the inferior of optic thalamus, the head of caudate nucleus, cerebellum, and

brain stem. Conclusion Acupuncture at Zusanli (ST 36) can increase

glycometabolism in the subcortical autonomic center related with functi ons of

internal organs, and PET is a feasible method for study on central mechanisms

of acupuncture.
