Effects of Electro-acupuncture on Regional cerebral blood flow and Regional cerebral glucose utilization / 全日本鍼灸学会雑誌

ABSTRACT

The effects of electro-acupuncture on the regional cerebral blood flow (rCBF) and regional cerebral glucose utilization (rCMRglc) are unknown.<br>We examined the rCBF and rCMRglc in five normal adult volunteers and ten patients with cerebrovascular accident and brain tumor using positron emission tomography (PET) in order to investigate the effects of acupuncture on functions of central nerve system.<br>The stimulation by electro-acupuncture was performed on HOKU and SHOU-SANLI on one side. Electro-acupuncture was done for 10 minutes, at the frequency of 2Hz to cause a slight muscle twich. The rCBF and rCMRglc in volunteers were mearsured before and after electro-acupuncture stimulation.<br>The results are as follows;<br>1) On the OM45mm slice image, stimulation to HOKU and SHOU-SANLI on one side increased the rCBF and rCMRglc of frontal and temporal lobe on the opposite side of stimulation.<br>2) On the OM80mm slice image, electro-acupuncture incrased the rCBF and rCBFglc of frontal and temporal lobe on both the right and left side.<br>These results suggest that stimulation of electro-acupuncture may influences the rCBF and rCMRglc.
