Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in three patient groups with arrhythmia(AP group), with arrhythmia and cerebral infarction(CI group), and with arrhythmia and hemorrhage(CH group), and then to find out the characteristic of meridian system among 3 groups. Methods : Thirty arrhythmic patients diagnosed by EKG, CT, and deficiency of the heart blood(心血虛症) were divided into 3 groups(AP, CI, CH group). Their electric potential of well and sea points in the meridians were measured 3 times by physiograph. Results : Measurements were analyzed by statistical factor analysis, we obtained that the left side electric potential of well and sea points in branches of the twelves meridians in AP group was divided into two factors, which were the hand meridian without the lung meridian, the foot meridian and the lung meridian, but the right side electric potential was divided into the hand and the foot meridian. In CH group both the left and the right side electric potential was divided into three factors. In CI group the left side electric potential was divided into three factors, but the right side electric potential was divided into two factors. Conclusions : In conclusion, their electrical potentials were different each other among 3 groups. Thus electrical potentials of well and sea points might be the representative meridian to show their characteristics.

Objectives : The characteristic of meridian system has been similar to this of electric potentials in human body. Therefore to measure the electric potentials in healthy volunteers and patients, and to find out the characteristic of meridian system and also to do that of differences between them. Methods : Twenty-nine healthy volunteers, thirty patients diagnosed as a cerebral infarction and wind-syndrome caused by hyperactivity of the liver-yang(肝陽化風) were examined into electric potential of well(井穴) and sea(合穴) points in branches of the twelve meridians by physiograph. Results : Measurements were analyzed by factor analysis, then we obtained that both the right and the left electric potential of well and sea points in branches of the twelves meridians in healthy volunteers were divided into two factors, hand meridian and foot meridian. Where as the left electric potential of those in patients with cerebral infarction were divided into three factors, one is foot meridian, another is hand meridian with the exception of large intestine meridian, and the other is large intestine meridian and also the right electric potential were divided into three factors, foot meridian, hand meridian with the exception of large intestine and lung meridian, and large intestine and lung meridian. Conclusions : In the results, healthy volunteers differ from patients in characteristic of electrical potentials, which means that we are able to catch the characteristic of meridian system by electrical potentials of well and sea points.

Background: As patients are positioned at insulated bed and practitioner are positioned at insulated floor or shoes, it could be a cause of lessening effect in acupuncture practice. We investigated how Ground connection could influence on the electrical meridian potential between practitioner and patient during acupuncture practice. Method: We treated 30 normal healthy subjects with acupuncture and measured changes in the electrical potential between the stomach meridian points ST-39 and ST-37 in response to light touch after insertion of a needle at ST-36. At first, we stimulated needle and measured electrical potentials for non ground, patient ground only, practitioner ground only, all ground, respectively. Result: All ground subject elicited positive mean potential $44.6{\pm}19.2{\mu}V$ and showed $181.4{\pm}59.7{\mu}V$ peak to peak potential. practitioner ground only showed negative mean potential $-51.5{\pm}9.3{\mu}V\;and\;367.4{\pm}27.8{\mu}V$ of peak to peak potential. Patient ground only revealed no mean potential as $2.9{\pm}1.3{\mu}V,\;16.4{\pm}11.9{\mu}V$ of peak to peak potential. All ground showed no mean potential as $1.6{\pm}0.7{\mu}V,\;3.3{\pm}1.9{\mu}V$ of peak to peak potential. respectively.

Human body has a complete left and right symmetry structure, and the left and right balance by Yin and Yang. When the balance is broken, the left and right Meridian becomes abnormal condition. Acupuncture is a kind of therapy to recover from energy unbalance of the left and right Meridian to a new balance condition. In the study, we observed the electric potential along the stomach meridian (ST) in order to verify the energy consensus phenomenon by transportation of bio-energy between operator and subject during acupuncture. The acupuncture effects on opposite meridian site were investigated by comparing the electric potentials between the right and left ST sites. Meridian electrical potentials (MEPs) between operator and subject were simultaneously generated during the acupuncture and the polarity of MEPs was opposite. The results might imply the bio-energy transportation between operator and subject. In addition, we observed three different patterns of MEPs on both ST sites which might represent the condition of the related meridians because meridians in the body are organically interconnected.

Objectives: The objective of this study is to investigate the effects of drinking alcohol on bio-electrical potential at twelve source points. Methods: Twenty healthy adults were assigned to alcohol and water groups by a random cross-over design. Bio-electrical potential at twelve source points were measured before and after drinking alcohol or water and the change of bio-electrical potential was analyzed and compared between the alcohol and the water groups. Results: Bio-electrical potential at LI4, ST42, KI3, PC7, TE4, GB40, LR3 in the alcohol group was significantly increased compared to those in the water group. Conclusions: Drinking alcohol increased bio-electrical potential at source points of LI, ST, KI, PC, TE, GB and LR in healthy human subjects.

Objectives : This study aimed to explore the passive multi-channel time series analysis method by measuring bio-potentials of acupuncture point and the peripheral region Methods : Bio-potential was measured at ST36 and the peripherical region of ST36 of 5 healthy volunteers at three times. The diagram of the potential changes over time were smoothed by moving average method and similarities of ST36 and the other points were calculated. Results : In the normal weight group, bio-potential similarity tended to decrease in proportion to the distance from the acupuncture point. In the obesity group, bio-potential similarity appeared in a very wide area. Bio-potential similarity had positive correlation with BMI value. Conclusions : The passive multi-channel time series analysis method showed the possibility be appropriate for the electrical characteristics study of meridians.

When a patient is positioned at insulated bed and practitioner is positioned at insulated floor, that condition could be a cause of lessening effect in acupuncture practice. We investigated how Ground connection and Insulation could influence on the electrical meridian potential between practitioner and patient during acupuncture practice. We treated 30 normal healthy subjects with acupuncture and measured changes in the electrical potential between the stomach meridian points ST-39 and ST-37 in response to light touch after insertion of a needle at ST-36. At first, we stimulated non-insulated needle and measured electrical potentials for non ground, patient ground only, practitioner ground only, all ground respectively. Then we used insulated needles and measured same as above. Non-insulated all ground subject elicited positive mean potential $44.6{\pm}19.2{\mu}V$ and showed $181.4{\pm}59.7{\mu}V$ peak to peak potential. Practitioner ground only showed negative mean potential of $51.5{\pm}9.3{\mu}V$ and $367.4{\pm}27.8{\mu}V$ of peak to peak potential. Patient ground only revealed no mean potential of $2.9{\pm}1.3{\mu}V$, $16.4{\pm}11.9{\mu}V$ of peak to peak potential. All ground showed no mean potential of $1.6{\pm}0.7{\mu}V$, $3.3{\pm}1.9{\mu}V$ of peak to peak potential. In case of Insulated condition, there elicited no mean potential. Non ground and Practitioner only showed weak value of peak to peak potential as $7.8{\pm}2.6{\mu}V$ and $8.4{\pm}2.5{\mu}V$ each. But patient only and all ground showed no potential as $4.7{\pm}2.2{\mu}V$, $3.4{\pm}2.2{\mu}V$, respectively. Therefore, Ground connection modulate the energy transfer course between practitioner and patient. Insulation block energy transfer but static electrical impulse between practitioner and patient.
