Objective : 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 twenty aged and fifty aged healthy volunteers groups at sleeping(SG) and awakening(AG), and then to find out the characteristic of meridian system among 2 groups. Methods : We selected who thirty healthy volunteers were diagnosed by a blood test, urine examination and differentiation of syndromes by five viscera(五臟辨證) among volunteers. Their electric potential of well and sea points in the meridians were simultaneously measured by physiograph. Results : Measurements were analyzed by statistical factor analysis, we obtained that the both left and right side electric potential of well and sea points in branches of the twelves meridians were unclearly divided into four factors according to age and whether sleeping or not, which were the three Yin meridians of the hand, the three Yang channels of the hand, the three Yin meridians of the foot, and the three Yin meridians of the foot. Conclusion : In conclusion, using the sequently measuring method, we obtained that electrical potentials of well and sea points in branches of the twelves meridians were divided into two factors, but the simultaneously measuring method, those were divided into four factors. The latter result means that the electrical potentials of twelve meridians were reflected by the function of the viscera and bowels.

Objectives : A previous study demonstrated that the connecting points of three yang meridians attenuated changes of nNOS, and Norepinephrine(NE) in rats. The current study investigated the changes in nNOS, NO and NE upon the needle insertion at varying depths at the connecting point of three yin meridians of the hand. Methods : Needles were inserted into rats, on both left and right sides of the connecting point, including the LU7, HT5 and PC6 acupoints which are three yin meridians of the hand. After insertion, needles were retained for five minutes. Each acupuncture groups were treated acupuncture at each acupoint and at the depths of superficial, middle and deep layer. After the retention, blood was drawn via cardiac puncture, and tissues of each point near meridian vessel was extracted to examine the changes in the expression of nNOS, NO and NE. Results : Compared with the superficial layer group, nNOS production significantly decreased in the middle and deep layer at LU7 acupoint group and in the deep layer at HT5, PC6 acupoint group. The tissue NE decreased in the deep layer on PC6 acupoint and the plasma NE increased at the middle layer at LU7 acupoint group but decreased at the deep layer on at LU7 acupoint group. Conclusions : Acupuncture at connecting points of three yin meridians of the hand can regulate the activities of nNOS, and NE.

To have effective treatment for shoulder arm pain, we searched the cause, symptom, etiology, classification of the pain areas, acupuncture points, and muscles along the meridians, and acquired the following results. Shoulder-pain is mainly divided into the malfunction of viscera and entrails, damage due to the weakness of essence and qi, abnormal status of muscle function, change of joints, disease in the nerve and vessel, and the internal injury due to seven modes of emotions. Pain of shoulder joints are pain in the local area of shoulder joints, referred pain of shoulder, neck, and shoulder-arm, numbnes and swelling of muscle, and muslce weakness. Shoulder-arm pain is classified as four types of pain: shoulder-joint pain, shoulder-back pain, shoulder-chest pain, and shoulder-arm-elbow pain. And shoulder-arm-elbow pain is again divided into the shoulder-blade pain, shoulder-arm pain, shoulder-elbow pain. The related meridians on shoulder pain are the three yin meridians of hand, Kidney Meridian, Conception Meridian, three yang meridians of hand, Bladder Meridian, Governor Meridian Acupuncture points for shoulder pain are in the acupuncture points of the 10 meridians and a-shi points. Thre related meridian muscles on shoulder-pain are the three yin and yang meridians of hand, and their related muscles are the ones that are connected with the front, back, and chest side muscles of shoulder joints, and the ones that are connected with the front and back side muscles of arm.

J$\bar{i}$n ji$\acute{e}$(根結) has been recognized as one of a meridian pathway. If you want to study a defense qi(衛氣) and nutrient qi(營氣)'s nature, function and operation, you could find a relationship of J$\bar{i}$n ji$\acute{e}$(根結) and the defense qi(衛氣). We proposed that, especially, J$\bar{i}$n ji$\acute{e}$(根結) has got a close relationship with a operation of the defense qi(衛氣). The ji$\acute{e}$(結) of three yang(三陽) located in ears and eyes, that are a starting point of the defense qi(衛氣) operation in the daytime and a one of five sense organs(五官). Gin, Liu, Zou and Ru (根, 溜, 注, 入) of the three yang(三陽) distinguished between the three yang(三陽) in the extremities. and in the symptoms of a disease of the three yang(三陽) on the bolt - leaf - hanges(關闔樞) theory, Greater yang(太陽) is related to the skin and flesh, Yang brightness(陽明) is related to the flesh and Lesser yang(少陽) is related to the muscle or bone. These skin, flesh, muscle and bone belonged to the five bodies(五體). The five bodies(五體) have relationship with the defense qi(衛氣)'s operation and function part. The ji$\acute{e}$(結) of three yin(三陰) located in neck, chest and abdomen. If we could catched the concepts on the ji$\acute{e}$(結) of three yin(三陰) and The Gin, Liu, Zou, Ru and ji$\acute{e}$(根, 溜, 注, 入, 結) position of three yang(三陽) altogether, we could suggested the theory of the entire area completed in the surface of body. so the defense qi(衛氣)'s protecting function of the whole body surface is achieved. In the symptoms of a disease of the three yin(三陰)'s the bolt - leaf - hanges(關闔樞) theory, greater yin(太陰) and reverting yin(厥陰)'s symptoms indicates the defense qi(衛氣)'s main action of a chest and abdomen. And lesser yin(少陰)' symptoms is about a vessle, that is not to mention on the five bodies(五體) of the three yang(三陽)'s symptoms, so here is mentioned the relationship of the defense qi(衛氣) and the five bodies(五體) strengthened. In the "J$\bar{i}$n ji$\acute{e}$ chapter(根結編) of Lin Shu(靈樞)", as the meridians of the foot (足經) was described, except the meridians of the hand(手經), it is reasonable to infer that the defense qi (衛氣) is relevant to the meridians of the foot(足經) than the meridians of the hand(手經).

By studying the portions and layers(分部), left and right, superior and inferior, location of yin and yang, and beginning and end of diseases of skin, which is the core point of the theory of cutaneous region(皮部論) in "Naejing(內經)", in the physiological and pathological perspective, based on opinion of historic memorial doctors, arrived to the conclusion as below. Cutaneous region means not only the distribution of three yin and three yang(三陰三陽) of the surface, but also inside and outside, shallowness and depth, and it is the system which unites meridians, networks, and vessels. It is divided into portions and layers. The origin and beginning of diseases and the rule of favorable pattern and unfavorable pattern can be known through it. The portion of skin is not only the area that meridian vessels belongs to skin, but also the area that activation of twelve meridian vessels are expressed in the surface. The layer of skin is consisted in order of skin-tertiary collateral vessel-collateral vessel-meridian vessel-bone. In "Naejing", there are two preconditions to divide three yin and three yang into yin and yang. The first is standing while looking the south, and second is the quotation "outside is side of yang(外者爲陽 內者爲陰)." According to this preconditions, yang of outside of yang brightness, lesser yang, and greater yang is the whole body, except inside of hand and foot which yin of lesser yin, pericardium, and greater yin. Superior and inferior of the portions and the layers is designated as hand and foot, theological basis of which superior and inferior work in same diagnostic method can be found in the root and the basis(標本) and the origin and the insertion(根結). In conclusion, cutaneous region not only manages layer of the skin, but also it is divided into layers and portions, so it has close relations between meridian vessels and collateral vessels. The in-depth study of cutaneous region and meridians should be progress, in order to practice of diagnosis and acupuncture and moxibustion more.

The following conclusions are drawn from a review on the theory of correlation between the jang-bu organs in 'Ojangchunchaklon(五臟穿鑿論)' which is quoted in 'Uihakipmoon(醫學入門)' and 'Donguibogam(東醫寶鑑)'. The three yangs and three yins are trisections each of yang ki and y1n ki. They represent three aspects of change in powers of yin ki and yang ki. The theory of Kaehapchu(開闔樞 the opening, closing and pivot) is thought to be the concept which explains the three states of jang-bu organs and meridians in terms of three yangs and three yins. The three yangs and three yins are assigned to twelve months according to the generation, prosperity and vanishment of the water, the fire, the wood and the metal in the circulation of nature with the lapse of time. Most of all, the change of the water and the fire is the main guide to the assignment. Both the theory of exterior-interior relations in jang-bu organs and meridians and the theory of Kaehapchu are founded on the assignment of three yangs and three yins to twelve months. The correlation between jang-bu organs is based on the monthly assignment of three yangs and three yins described in 'Internal classic(內經)' and the theory of Kaehapchu. In the correlations between jang-bu organs and meridians, the exterior-interior relations are the correspondences of Hand to Hand and Foot to Foot. but the relations of Kaehapchu are those of Hand to Foot and Foot to Hand. Jeesan's diagram of pulse is grounded on the correlations between jang-bu organs. On the left of the diagram, jang organs are arranged in the order of hierarchic positions in body. On the right, bu organs are disposed according to the correlations with the jang organs. Jeesan's diagram includes the principles of triple harmony and diagonal groups in twelve earthly branches(十二支). Jeesan's diagram is the frame through which correlations of jung-ki-shin-hyul, five jang and six bu organs, twelve meridians and six intrinsic factors can be observed at once.

Biophotons from three healthy subject's hands were measured every Friday for one year. The correlation coefficients between the left and right palms were found to be 9.0, and a similar value was also obtained between the left and right back of hands. However, the correlations between the palm and back of a hand turned out to be low, on the average only 0.5. These results are consistent with the result of Zhang's $CO_2$ production rate experiments on the acupuncture points. The high correlation between the left and right, and the low correlation between the palm and back are interpreted according to the acupuncture theory of meridians. The palm and the back correspond to the yin and yang meridians, respectively. And their behaviors are rather opposite, thus they show low correlations.
