The following conclusions were made in comparison with EAV measurement values and Type(SaSang Constitution Classfication). 1) The analsis of the Correlation in Normal group with EAV measurement values and Type(SaSang Constitution Classfication). 2) The analysis of the correlation in patient group with EAV measurement values showed significant differences in Right meridians(Nerval degeneration vessel, Circulation, Allergy) and in Left meridian(Liver). 3) The analysis of the correlation in Total(Normal+patient)group with EAV measurement values showed significant differences in Right meridians(Large intestine, Nerval degeneration vessel, Circulation, Allergy, Pancreas) and in Left meridians(Lymph vessel, Nerval degeneration vessel, Spleen, liver). 4) The above results showed common-significant differences in Right Allery meridian and in Left Liver meridian. 2. The analysis of the correlation in EAV measurement values and Group (Cerebrovascular accident) showed significant differences in Right meridians(Lymph vessel, Lung, Nerval degeneration vessel, Allergy, Paren & Epith. degeneration vessel, Triple warmer, Heart, Pancreas, Stomach, Fibroid degeneration vessel, Skin, Fatty degeneration vessel, Heart, Stomach, Fibroid degeneration vessel, Skin, Fatty degeneration vessel, Bile duct, Kidney). 3. The analysis of the correlation in EAV measurement values and Para(GROUPS according to PARALYSIS)showed significant differences in Left Stomatch meridian. The analysis of the correlation in EAV measurement values and Para(GROUPS according to PARALYSIS) about the differance of right measurement values and left measurement values showed significant differences in Nerval degeneration vessel, Stomatch, Gall bladder & Bile duct, Kidney and Urinary Bladder meridians. 4. The analysis of the correlation in EAV measurement values and Compl(GROUPS according to COMPLICATION with CVA)showed significant differences in Right meridians(Lymph vessel, Articular degeneration vessel, Fatty degeneration vessel) and in Left meridians(Lung, Stomatch, Fatty degeneration vessel). 5. The analysis of the correlation in Type and MORPHOROGICAL DIAGRAMING (HTOUPS according to MORPHOROGY) showed significant differences in Cranium region, Chest region, Stomatch region and Umbilicum region. 6. The analysis of the correlation in BAZ measurement values and Group(Cerebral Vascular Attack)showed significant differences, the analysis on the correlation of BAZ measurement values and Type(SaSang Constitution Classfication) didn't show any significant differences. 7. In comparison with Actual measurement vales and Voll's measurement values, BAZ measurement values agree with Voll's measurement values but CMP measurement values lower than the Voll's measurement values. Later We have to research further about classifications of race, age, sex etc. The EAV measurement values have Group(Cerebrovascular accident) more correlative than Type(SaSang Constitution Classfication). The EAV may well be that it will be used as an accessory method in SaSang Constitution Classfication and as a diagnostic method in medicine too.

Objectives: To investigate the effects of acupuncture at GV20 and EX-HN1 on cerebral blood flow (CBF) velocity and cerebrovascular reactivity (CVR) in the middle cerebral arteries (MCA) and anterior cerebral arteries (ACA) and to compare the effects to acupuncture at GV20. Methods: The study was a randomized, crossover trial that included 10 healthy men aged 20 to 29 years who underwent acupuncture treatment four times with a washout period of one week. The CBF velocity and CVR were measured by transcranial Doppler sonography (TCD) on both MCAs at the first and second visits, and both ACAs at the third and fourth visits. Participants were randomly assigned to one of two groups (A and B) before the first and third visits. Group A received two phases of acupuncture intervention at a single GV20 point and a combination of GV20 and EX-HN1 acupoints. Group B received the same interventions, but in the reverse order. Results: The increase in CO₂ reactivity was significantly higher for the combination acupoints of GV20 and EX-HN1 than for the GV20 single acupoint in both MCAs (Right: 136 to 178, p=0.017; Left: 127 to 191, p=0.017) and ACAs (Right: 133 to 158, p=0.013; Left: 122 to 168, p=0.025). No significant change was noted in the corrected velocity at PETCO₂ 40 mmHg, blood pressure, or heart rate. Conclusions: The findings suggest that improvement of the CBF in the MCA and ACA after GV20 acupuncture increases when acupuncture is also performed at EX-HN1. These results clinically support the combined use of EX-HN1 and GV20 to treat disorders of MCA and ACA circulation.

Hemodynamic information in the carotid artery bifurcation is very important for understanding the development and progression mechanisms of cerebrovascular disease and for its early diagnosis and prediction of the progress. In this paper, we constructed a mock pulsatile blood circulation system using an anthropomorphic elastic vessel of the carotid artery bifurcation and ex vivo pig blood to acquire ultrasound images from blood and vessels synchronized with internal pressure while controlling the blood flow. Echogenicity, blood flow velocity, and blood vessel wall motion from the ultrasound images, and internal blood pressure were extracted over a cycle averaged from five cycles when the pulsatile pump rates are 20 r/min, 40 r/min, and 60 r/min. As a result, respectively, the peak systolic blood flow velocities were 20 cm/s, 25 cm/s, and 40 cm/s, the blood pressure differences were 30 mmHg, 70 mmHg, and 85 mmHg, the arterial walls were expanded to 0.05 mm, 0.15 mm, and 0.25 mm. Time-delayed cyclic variation of echogenicity compared to blood flow and pressure was observed, but the variation was minimal at 20 r/min. Time-synchronized cyclic variations of these parameters are important information for accurate input parameters and validation of the computational hemodynamic experiments which will provide useful information for the development and progress mechanisms of carotid artery stenosis.

Citri Reticulatae Viride Pericarpium extract(CRVP) have been used in oriental medicine for many centuries as a therapeutic agent for Soothing the liver and regulating the circulation of qi(疏肝理氣), and promoting digestion and removing stagnated food(消積化滯). The effects of CRVP on the vascular system is not known. The purpose of this Study was to investigate the effects of CRVP on the pial arterial diameter and regional cerebral blood flow(rCBF) in normal rats and ischemic cerebrovascular pathologic model rats. The changes in rCBF was determinated by Laser-Doppler Flowmetry(LDF), and the changes in pial arterial diameter were determinated by video microscopy methods and video analyzer. The results were as follows ; 1. Pial arterial diameter was significantly increased by CRVP in a dose-dependent manner. 2. Pretreatment with L-NNA significantly inhibited CRVP induced increased rCBF and pial arterial diameter. 3. Both the methylene chloride fraction and the hexane fraction of CRVP dose-dependently improved the altered cerebral hemodynamics of cerebral ischemic animal by increasing rCBF. 4. Pretreatment with L-NNA and indomethacin significantly inhibited CRVP(MC) induced increased rCBF. 5. Pretreatment with L-NNA and indomethacin significantly inhibited CRVP(hexane) induced increased rCBF. 6. Pretreatment with CRVP maredly stabilized the changes rCBF and pial arterial diameter during the period of cerebral reperusion. In conclusion, CRVP causes a diverse response of rCBF and pial arterial diameter, and CRVP dose-dependently improved the altered cerebral hemodynamics of cerebral ischemic animal by increasing rCBF and pial arterial diameter. These results suggest that the improvement of cerebral hemodynamics is also mediated by nitric oxide synthase and cyclooxygenase.

Moyamoya disease is an unusual cerebrovascular disorder characterized by occlusive intimal dysplasia of the distal internal carotid and proximal cerebral arteries, but the etiology remains unclear. Angiographic characteristics include bilateral stenosis or occlusion of the terminal portions of the intracranial internal carotid arteries and bilateral development of fine collateral vessels at the base of the brain known as ‘Moyamoya vessels’. Cardiac surgery using cardiopulmonary bypass due to coronary artery disease and others among patients with moyamoya disease is very rare, and cardiac surgery for such patients has a potential risk of intraoperative and perioperative brain ischemia. We successfully treated a patient who underwent artrial septal defect closure and coronary artery bypass graft using the cardiopulmonary bypass, so we report this case with a brief literature review.

1. The Pung(風) is the necessary power for growth and maintenance of life. 2. The characteristics of the Pung(風) is the Yang evil, the features for opening and excretion, mobility and rapid change. That is the major cause of all diseases, and its mobility is the main character. 3. Jung Pung(中風) is the same concept of apoplexy in Western medicine. 4. Jung Pung(中風) is classified on the basis of pathology, anatomy, and histology in Western Medicine, but In Oriental Medicine that is classified on the basis of symptom and severity of disease. 5. In Western Medicine, Jung Pung(中風) was regarded as the local cause of disease, but in Oriental Medicine regarded as the physiological changes caused by the weakness of the whole body. 6. In the emergency care, the method of GaeKeum is compared to Levin tubing, the method of to the use of urokinase for the promotion of cerebrovascular circulatio, and the method of To(吐法) to suction for the elimination of Dam(痰), the method of Hun(熏法) to the use of solution for the improvement of circulation. 7. With the comparison of the cause and diagnosis, the hemorrhagic disease and infarction were regarded as the major agents in Western Medicine and the symptom appeared in the patient was the standard of diagnosis and therapy in Oriental Medicine. 8. In the Western therapy of cerebral hemorrhage, the method of coagulation and hemostasis was used for the elimination of hematoma and cerebral edema, but in Oriental Medicine, the method of YanghaelGiHael(凉血止血) was used for descending the PungHwa(風火) and hemostasis. 9. In the period of recovering injury, the physical therapy was underlined for the recovering of partial function in Western Medicine, the method of accupuncture and drug therapy was adapted for the normal function of the whole body.

Purpose: As emergency medical service fund is further expanded due to amendment of the law on emergency medical services in 2008, Korean government has prepared to intervene in a comprehensive manner to strengthen a trauma treatment system. As a result, it announced a master plan to establish a serious trauma treatment center in 16 areas across the nation. Therefore, this study has attempted to investigate the current status of the serious trauma treatment centers and suggest the goal and improvement plan of future serious trauma treatment centers. Methods: As of 2011, Korea operates 23 emergency cerebrovascular service centers, 23 emergency heart disease centers and 35 severe trauma treatment centers across the country. 12 emergency medical service centers have been chosen among the serious trauma treatment centers. Then, top six (6) centers chosen at Emergency Medical Institute Assessment 2011 by Ministry of Health and Welfare have been selected, and floor layout and spatial allocation by usage have been reviewed and analyzed. Results: Consequently, this study has investigated the spatial components, circulation layout and spatial allocation of a serious trauma treatment. For construction planning in consideration of the fundamental objectives and goal of emergency medical services, it is essential to allot spaces and select exact spatial components. It appears that it is necessary to design spaces for emergency medical services and come up with construction planning through appropriate spatial allocation.

Objectives: This study was designed to investigate the effects of Calculus Bovis-Fel Uris-Moschus pharmacopuncture (BUM) on the regional cerebral blood flow (rCBF) and the mean arterial blood pressure (MABP) in normal and cerebral ischemic rats and to investigate a possible pathway involved in the effects of BUM. Methods: The changes in the rCBF and the MABP following BUM into Fengfu (GV16) were determined by using a laser-Doppler flow meter and a pressure transducer, respectively. Results: BUM significantly increased the rCBF and decreased the MABP in normal rats in a dose-dependent manner. The effect on the rCBF was significantly inhibited by pretreatment with methylene blue (0.01 mg/kg, intraperitoneal), an inhibitor of guanylate cyclase, but was not affected by pretreatment with indomethacin (1 mg/kg, intraperitoneal), an inhibitor of cyclooxygenase. The BUM-induced decrease of the MABP was changed neither by methylene blue nor by indomethacin pretreatment. In the cerebral ischemic rats, the rCBF was stably increased upon cerebral reperfusion in the BUM group in contrast to the rapid and marked increase in the control group. Conclusion: This study demonstrated that BUM into Fengbu (GV16) increased the rCBF in a dose-dependent manner in the normal state; furthermore, it improved the stability of the rCBF in the ischemic state upon reperfusion. Also, the effects of BUM on the rCBF were attenuated by inhibition of guanylate cyclase, suggesting that the effects involved the guanylate cyclase pathway.

Objective : Superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis is conducted for flow augmentation. In this study, we measured the STA cut flow of a Korean population and evaluated the relationship between STA cut flow and long-term patency of the bypass. Methods : A retrospective study was conducted. Intraoperative measurement of STA flow was conducted using a microvascular flow meter on patients who underwent STA-MCA. After cutting the distal end, the STA flow rate was measured with no resistance and recorded. After finishing anastomosis, STA flow was measured and recorded. The cut flow index was calculated by dividing post anastomosis flow by cut flow in intracranial atherosclerotic stenosis patients. Results : The median STA cut flow was 35.0 mL/min and the post anastomosis flow was 24.0 mL/min. The cut flow of STA decreased with aging (p=0.027) and increased with diameter (p=0.004). The cut flow showed no correlation with history of hypertension or diabetes mellitus (p=0.713 and p=0.786), but did correlate a positively with history of hyperlipidemia (p=0.004). There were no statistical differences in cut flow, STA diameter, and post anastomosis flow between the frontal and parietal branches (p=0.081, p=0.853, and p=0.990, respectively). Conclusion : The median STA cut flow of a Korean population was 35 mL/min. Upon reviewing previous articles, it appears that there are differences in the STA cut flow between Western and Asian patients.

Background and Objectives: Despite remarkable reduction in cardiovascular disease (CVD) mortality, the burden has remained the leading cause of death. Since little research has focused on regional disparity in CVD mortality, this study aims to investigate its spatiotemporal trends in Korea from 1983 to 2019. Methods: Using the causes of death statistics in Korea, we analyzed the geographic variation in deaths from CVDs from 1983 to 2019. The sex and age-standardized mortality rate was calculated according to the 17 administrative regions. The analyses include all diseases of the circulatory system (International Classification of Diseases-10 codes, I00-I99), along with the following 6 subcategories which were not mutually exclusive: total heart disease (I00-I13 and I20-I51), hypertensive heart disease (I10-I13), ischemic heart disease (I20-I25), myocardial infarction (I21-I23), heart failure (I50), and cerebrovascular disease (I60-I69). Results: Overall, heart failure death rate increased across all regions, and other CVD death rates showed a decreasing trend. Regional disparity in mortality was substantial in the early 1980s but converged over time. In all types of cardiovascular mortality, Busan, Ulsan and Gyeongnam remained the highest, although they showed a downward trend like other regions. Jeju continued to have a relatively low CVD mortality rate. Conclusions: The regional disparity substantially decreased compared to the 1980s. However, the relatively high burden of CVD mortality in the southeastern region has not been fully resolved.
