Objectives : The meridian system is a systematic complex of empirical knowledge, which functions as a basis of acupuncture treatment. In this article, we reviewed the visualization methods of meridian and acupuncture points through the investigation of the characteristics of Diagram of Meridians, Mingtang Diagram, Diagram of Meridians and Collaterals, Bronze Statues and Diagram of Bronze Statue. Methods : We investigated the characteristics of Diagram of Meridians, Mingtang Diagram, Diagram of Meridians and Collaterals, and Bronze Statues. We reviewed the visualization methods of meridian and acupuncture points in those classical Diagrams and analyzed their relationships among them. Results : In order to explain the meridian and acupuncture points easily, ancient people usually used drawings which are named Mingtang Diagram, Diagram of Meridians and Collaterals, by their own characteristics. Owing to their limitations of drawings on the 2 dimensional plane, Chinese people designed the Bronze Statue for Acu-moxibustion and its first invention was invented in Tiansheng age of Song dynasty. For several decades and centuries, these models and drawings were inherited, also reflecting variations of meridian system. As the Bronze Statue has a deficiency in the educational use because of its limitations of mass production, Diagram of Bronze Statue drawn on the 2 dimensional plane was invented. At the beginning of Mingtang Diagram, Diagram of Meridians and Collaterals, Diagram of Bronze Statue and Bronze Statue, their own characteristics were significantly differed with other diagrams and statues. We found that both diagrams and statues were gradually combined with description of the relationship between internal organs and the skeletal structure and the meridian system. Conclusions : Our findings suggest that Diagram of Meridians, Mingtang Diagram, Diagram of Meridians and Collaterals, and Bronze Statues are the basic form of data visualization, one of the infographics. We suggest that ancient Chinese people intend to explain the empirical knowledge using the ancient infographics of meridian system, but have limitations on reflecting theorical or abstractional meaning.

The basal ganglia network has been implicated in the control of adaptive behavior, possibly by integrating motor learning and motivational processes. Both positive and negative reinforcement appear to shape our behavioral adaptation by modulating the function of the basal ganglia. Here, we examined a transgenic mouse line (G2CT) in which synaptic transmissions onto the medium spiny neurons (MSNs) of the basal ganglia are depressed. We found that the level of collaterals from direct pathway MSNs in the external segment of the globus pallidus (GPe) ('bridging collaterals') was decreased in these mice, and this was accompanied by behavioral inhibition under stress. Furthermore, additional manipulations that could further decrease or restore the level of the bridging collaterals resulted in an increase in behavioral inhibition or active behavior in the G2CT mice, respectively. Collectively, our data indicate that the striatum of the basal ganglia network integrates negative emotions and controls appropriate coping responses in which the bridging collateral connections in the GPe play a critical regulatory role.

Objective : Blood disease is common these days due to modern man's excessiveness in Yang heat (陽熱) and vulnerability of the Eum blood(陰血). This exposes them to warmheat/ dampness-heat diseases, where pathogenic heat easily penetrates the blood dimension(血分) creating stagnated blood(瘀血). Consequently, pathogenic symptoms in the collateral vessels increase, making it crucial to understand the pathogenic mechanism of the disease. Method : This paper examines the condition and region of the collateral vessel diseases(CVD) according to the blood diseases of Onbyeong, by analyzing each prescription's matching symptom. The disease in question in this paper is 'stagnated blood fixated in the collateral vessels'. Therefore diseases with stagnated blood in the Yang collaterals and Viscera collaterals or viscera themselves from the chapter of "On-Yeok-Ron(溫疫論)", and < Dry Blood-DaeWhangJaChungWhan(大黃蟅蟲丸) > chapter of "Geum-Gue-Yo-Rak(金匱要略)", were examined respectively. Result & Conclusion : The process of CVD according to the blood diseases of Onbyeong can be summarized as follows. First, bleeding in the Yang and Bowel collaterals, then stagnation in the Yang and Bowel collaterals, and finally stagnation in the viscera collaterals or Liver itself. The refractory nature of blood stagnation symptoms of the collateral vessels is mainly due to the characteristics of the collateral vessel itself. In structure, they are very narrow and small, situated at the most terminal part of the body where it is difficult for the Jeong Gi(精氣) to reach. Also, as they are symptomatic of degeneration of Jeong Gi, the root of the disease is very deep. Therefore to resolve blood stagnation in the cases of Ju-Gaek-Gyo and Dry Blood, general approaches using 'Gi communication(行氣)' or 'Blood vitalizing(活血)' medicinals will not suffice. Special medicinals such as crustacean and insects need to be appropriately applied.

For the purpose of experimental and clinical studies on the 14 channels and collaterals, we performed an inquiry on the anatomical mapping of neronal, circulatory and muscular networks in the human body which possibly correspond to the major pathway of Du channel and Ren channel known to be critical for overall controlling and mediating 12 regular channel connections. The theoretical background of this analysis was based on the oriental medicinal treatises which described acu-points and related anatomical informations. We suggest that rearrangement methodology for the 12 regular channels as described here may be applied to other 12 regular channels and to develop the new concept on the elucidation of the medical efficacy based on precise anatomical localization of channels and collaterals as well as the meridian points. It is proposed that interdisciplinary studies between oriental and western medicine are critical for more efficient achievement.

Pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals is a rare and complex lesion in which great morphologic variability exists regarding the sources of pulmonary blood flow. We report a case of this disease with no true central pulmonary arteries in a 9-month-old-boy successfully treated by one-stage complete unifocalization and repair from a midline stemotomy approach.

Sokmyeungtang was the representative prescription for Apoplexy under the rule of Tang and Song dynasty of which the cultures were thriving in the history of China. However, the clinical use of Sokmyeungtang has been gradually reduced since Geumwon dynasty of China because it was misunderstood that the dryness heat drugs of pungent in flavor and warm in property such as Ephedra, Pubescent Angelica Root, Chinese Cassia Tree-Bark, Divaricate Saposhnikovia Root, Prepared Aconite Root, Fresh Ginger, and Wildginger Herb included in the presciption for Apoplexy supplemented heat as damaging Yin flood. In fact, the drugs pungent in flavor and warm in property activate exterior and interior circulation, circulate channels and collaterals, promote blood circulation, and remove blood stasis with the side effect of relieving exterior syndrome with drugs warming channels. When treating Apoplexy with Sokmyeungtang, the cold drugs such as Gypsum, Baikai Skullcap Root, and Pueraria Root are prescribed to suppress fire of pungent dryness and to control excessive heat of people with Apoplexy as reducing the effects of hot drugs causing impairment of Yin. For treatment of Apoplexy, the above drugs accelerate blood and Qi circulation in channels and collaterals and then in necrotic tissue of human body as removing blood stasis. Consequently, these drugs improve disorders of capillary tube circulation. If Sokmyeungtang, an old prescription, is properly understood, it will be substantially helpful to all kinds of treatments in clinical cases

Internal carotid artery (ICA) trapping can be used for treating intracranial giant aneurysm, blood blister-like aneurysms and ICA rupture during the surgery. We present a novel ICA trapping technique which can be used with insufficient collaterals flow via anterior communicating artery (AcoA) and posterior communicating artery (PcoA). A patient was admitted with severe headache and the cerebral angiography demonstrated a typical blood blister-like aneurysm at the contralateral side of PcoA. For trapping the aneurysm, the first clip was placed at the ICA just proximal to the aneurysm whereas the distal clip was placed obliquely proximal to the origin of the PcoA to preserve blood flow from the PcoA to the distal ICA. The patient was completely recovered with good collaterals filling to the right ICA territories via AcoA and PcoA. This technique may be an effective treatment option for trapping the aneurysm, especially when the PcoA preservation is mandatory.

A 6-month old girl who had pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals underwent one-stage complete repair with unifocalization through a bilateral thoracosternotomy(clamshell incision). There were no serious postoperative compli cations, and the postoperative echocardio-graphy showed no residual ventricular septal defect or significant pulmonary artery stenosis. In this condition, great surgical variability exists regarding the sources of pulmonary blood flow. Recent clinical work has focused on a one-stage complete repair. The potential advantages of the clamshell incision are apparent in terms of mediastinal approach, postoperative results, and safety.

To compare the myocardial viability in patients suffering from total occlusion of the right coronry artery (RCA) with the angiographic collaterals, intracoronary injection of Thallium-201 (T1-201) was done to 14 coronary artery disease (CAD) patients (pts) with total occlusion of RCA and into four normal subjects for control. All 14 CAD pts had Grade 2 or 3 collateral circulations. There were 14 male and 4 females, and their ages ranged from 31 to 70 years. In nine pts, T1-201 was injected into left main coronary artery (LCA) ($300{\sim}350{\mu}Ci$) to evaluate the myocardial viability of RCA territory through collateral circulations. The remaining five pts received T1-201 into RCA ($200{\sim}250{\mu}Ci$) because two had intraarterial bridging collaterals and three had previous successful PTCA. Planar & SPECT myocardial perfusion images were obtained 30 minutes, and four to five hours after T1-201 injection. Intravenous T1-201 reinjection (six pts) or $^{99m}Tc-MIBI$ (two pts) were also performed in eight CAD pts. Intracoronary myocardial perfusion images were compared with intravenous T1-201 (IV T1-201) images, ECG, and ventriculography. Intracoronary T1-201 images proved to be superior to that of IV T1-201 due to better myocardial to background uptake ratio and more effective in the detection of viable tissue. We also found that perfusion defects were smaller on intracoronary T1-201 images than those on the IV T1-201. All of the 14 CAD pts had either mostly viable myocardium (seven pts) or large area of T1-201 perfusion (seven pts) in RCA territory, however ventriculographic wall motion and ECG did not correlate well with intracoronary myocardial perfusion images. In conclusion, total RCA occlusion patients with well developed collateral circulation had large area of viable myocardial in the corresponding territory.

Objectives: Recently, the effect of acupuncture has been approved not only in the East but also in the West, so the interest on acupuncture was greatly improved. Especially, functional magnetic resonance imaging(fMRI) was embossed as the study tool for the mechanism of acupuncture noninvasively and many studies on the mechanism of acupuncture using fMRI were carried out. We archived the fMRI study on the brain activity induced by manual acupuncture at BL62(申脈). Methods: The study was the acupuncture at BL62(申脈) and we acquired 9 fMRI results from 6 persons$(age\;20{\sim}30,\;4\;male\;and\;2\;female)$. These studies employed The block design for mapping brain activity and acupuncture was perfomed at BL62(申脈) on the left foot. Results: The brain related motor function was cerebellum, basal ganglia and cerebral cortex and thalamus connected these elements. In the result of this study, the regions of significant activation in the cerebellum was centered on the spinocerebellum in the anterior lobe, so we presumed that this result showed the input of stimulation by the acupuncture on BL62(申脈). But basal ganglia and cerebral cortex showed the regions of significant activation in the left larger than the right and regions of the cerebral cortex was the motor and sensory cortex. Such a result explained that acupuncture at BL62(申脈) could have influence the motor function and acupuncture at left BL62(申脈) could affect the right side through the activation of the left basal ganglia and cerebral cortex. Conclusions: In the theory of crossing needling at collaterals(繆刺論), it the pathogenic factor invaded in the Yang Heel channel(陽?脈) that was one of the eight Extra meridians(奇經八脈), we recognized the disease of the collateral channel and used contralateral BL62(申脈) for treatment of the Yang Heel channel(陽?脈). Moreover the result of this study could bear the construction that acupuncture at the left BL62(申脈) treats the contralateral lesion and this construction is related to the theory of crossing needling at collaterals(繆刺論).
