The Comparative Study of NIRS and Eastern Medicine Phenomenon in the Meridian Point Commonly Used for Pain Relief

Abstract

We showed that the brain areas such as the thalamus, insula and anterior cingulate cortex were activated by heating the tail of monkeys in 47 C water and those activations were suppressed by electroacupuncture (EA) at ST36 and LI4 acupoints, and that histamine and dopamine release was increased after pain stimulus in rats and the changes were completely abolished by EA at ST36 and ST37 acupoints and that different manual acupuncture at ST36 appear to change the neural coding of electrical signals in the spinal dorsal horn through WDR neurons in rats. In this meeting we will show with Near-infrared Spectroscopy and the interview sheet about the Eastern medicine complaint that the subjects whose center-of-gravity value are lighter than a standard value are “blood deficiency”, the subjects whose center-of-gravity value is heavier than a standard value are “blood stasis”, the subjects whose integration value are higher than a standard value are “qi stagnancy” or normal, and the subjects whose integration value are lower than a standard value are “qi deficiency” and that acupunture stimulation on SP6 or on ST36 balanced regional cerebral blood flow (rCBF) but that on LU6 decreased rCBF, and that the simultaneous acupunture stimulation on DU20 and Ex-HN4 reduced rCBF at the frontal cortex. However, independent acupunture stimulation on DU20 or Ex-HN4 failed to change rCBF. We would like to also report change of rCBF by pain and painkilling.
