Objectives : The aim of this study was to understand electro-physiological peculiarity in meridian and acupoints, and understand acupuncture therapy mechanism as an electro-physiological viewpoints. Methods : I reviewed the articles on the electro-physiological peculiarity of the meridian and acupoints Results and Conclusions : It has been reported that meridian and acupoints have high-electrical conductivity and row-electrical resistance. On this scientific basis, to understand the mechanism of acupuncture therapy, I made some hypotheses. At first, there is electro-property in meridian and acupoint. The second, energy flowing in meridian is related with electro-property. The third, there is electronic interaction between practitioner of acupuncture therapy and patient receiving acupuncture therapy. The forth, acupuncture effects which may be expressed by the electro-charge capacity is transfered between practitioner and patient via acupuncture. Electro-charge induced via acupuncture in practitioner may be an important factor that initiate the electro-charge changes in meridian and acupoint of patient.

Objectives : The aim of this study was to investigate the effect of low frequency electro-acupuncture at ST39 on intestinal motility in rats. Methods : Intestinal hypermotility and hypomotility in rats were induced by oral carbachol ingestion and loperamide injection. Rats were divided into seventeen experimental groups including the normal and holder groups. The rats were induced with intestinal hypermotility and hypomotility and divided into pre and post-treatment groups. I also carried out acupuncture (needle retention) and low frequency electro-acupuncture at ST39 or the sham point. I fed charcoal to rats after the treatment and calculated its distance travelled in the gastrointestinal tract, which was compared by groups so as to determine which treatment was more effective in increasing or decreasing intestinal motility. Results : 1. In normal rats, low frequency electro-acupuncture at ST39 showed no significant effect on intestinal motility. 2. Pre-treatment with acupuncture (needle retention) at ST39 on intestinal motility over-activated with carbachol significantly decreased intestinal motility in rats. 3. Pre-treatment with low frequency electro-acupuncture at ST39 on intestinal motility over-activated with carbachol significantly decreased intestinal motility in rats. 4. Pre-treatment with acupuncture (needle retention and low frequency electro-acupuncture) at ST39 showed no significant effect on intestinal hypomotility in rats that was induced by loperamide injection. Conclusions : These results suggest that acupuncture (needle retention) and low frequency electro-acupuncture at ST39 have preventive effects on intestinal hypermotility. Regardless of the stimulation method, ST39 showed an effect on intestinal motility. Further study is required to confirm other effects of ST39.

Objectives This study was performed to evaluate the effects of acupuncture, electro-acupuncture and acupuncture with pulsed electromagnetic therapy on upper extremity of healthy people and hemiplegic patients by D.I.T.I.. Methods 20 healthy people and 20 hemiplegic patients caused by stroke were selected. They have been treated three different types of treatment; acupuncture, electro-acupuncture and acupuncture with pulsed electromagnetic therapy. And skin temperature of upper extremity has been measured before and after each treatment by D.I.T.I.. The thermographic data was analyzed by 'Independent T-test' and 'Repeated measures ANOVA test'. Results 1. In healthy group, there was very statistical significant difference (p<0.001) of the amount of thermal change by each treatment, and the amount of change was arranged in descending order; acupuncture with pulsed electromagnetic, acupuncture and electro-acupuncture. 2. In hemiplegic group, the skin temperature of hemiplegic side was $0.97^{\circ}C$ cooler than non-hemiplegic side. 3. Skin temperature of all hemiplegic patients was increased after acupuncture treatment. 4. In hemiplegic group, there was statistical significant difference (p<0.05) of the amount of thermal change by each treatment, and the amount of change was arranged in descending order; acupuncture with pulsed electromagnetic, acupuncture and electro-acupuncture. Conclusions The results indicate that acupuncture, electro-acupuncture and acupuncture with pulsed electromagnetic therapy had good effect on the change of skin temperature by stimulating sympathetic nervous system.

Objectve : Recent stuides suggested that there is a strong correlation between acupuncture stimulation and its cortical activation. Another study showed that either positive or negative BOLD effects could be observed depending on anatomical structure in acupuncture. Methods : 1) Subjects and paradigms: Two separate stimulation paradigms were performed in this study. To see the effects of electro-acupuncture stimulation on K7(Fuliu), the experiment was carried out on six healthy volunteers, using the gradient echo sequence with the 3.0T whole-body MRI system(ISOL). After the needle insertion on right K7(Fuliu), 2 Hz of electric stimulation was given for 30 seconds, repeated five times, with 30 seconds' intervals. During the intervals while there was no electro-stimulation, the subjects performed motor task as a reference. The image analysis including motion correction, talairach transformation, and smoothing was done using SPM99. Results: The electro-acupuncture stimulation on K7(Fuliu) activated Brodmann's Areas of 9, 19, 23, 24, 31, 32, 39 which may be the central pathways of the electro-acupuncture stimulation on K7(Fuliu) and those brain areas may be related with the function of the electro-acupuncture stimulation on K7(Fuliu).
