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

Purpose: The purpose of this study was to investigate how induced microcurrent shoes influenced changes of the blood circulation in patients with Plantar Fasciitis. Methods: Initially, the subjects were comprised of 5 males and 5 females, who agreed with this research and are more than fifty years old, but 4 of those were dropped during the experiment. They all have plantar fasciitis and pain on their feet. Subjects wore the induced microcurrent shoes for more than 4 hours everyday during 4 weeks. When they wore those shoes, they also wore the specially produced shocks made of silver-mixed thread and they were asked to avoid intense exercise. Assessments were carried out before and after walking on a treadmill and we measured changes between the test before and after 4 weeks. In the examination of the before test, general shoes were used, and in the examination of the after test, induced microcurrent shoes were used. Temperature difference was measured by thermograpy DOREX spectrum 9000MB(USA). Subjects walked total 20 minutes and during gait, the walking rate on a treadmill was increased from 2Km/h to 3Km/h after 10 minutes. We measured plantar temperature by thermograpy especially both heel, 1st, and 5th metatarsal areas. Results: Firstly, in comparison of the blood circulation on the left and right foot at 0 week and 4 weeks, it tended toward increasing blood circulation but there was. no statistically significant difference (p>0.05). Secondly, in comparison of the blood circulation before and after treadmill with the induced microcurrent shoes, the blood circulation of the heel and the 5th area on the right foot was increased to all subjects(p<0.05). Conclusion: The results of this study revealed that subjects showed tendency to increase blood circulation in both right and left feet after wearing microcurrent shoes and specially after walking treadmill at 4 weeks. Therefore induced microcurrent shoes are useful to improve blood circulation for patients with plantar fasciitis.

Purpose: This study was done to investigate the effect of self-foot reflexology on peripheral blood circulation, peripheral neuropathy and to determine the feasibility of self-foot reflexology as a nursing intervention. Method: This was nonequivalent control pretest-posttest study with 76 patients with type 2 diabetes mellitus (ages between 40-79) recruited from public health centers in Busan city. Intervention was a 6 week self-foot reflexology, and outcome variables were peripheral blood circulation and peripheral neuropathy(tactile response to monofilament, intensity of symptoms of peripheral neuropathy). ANCOVA was used to do the statistical analysis. A.05 significance level was set for evaluating the effects of self-foot reflexology. Results: The self-foot reflexology was relatively effective not only in reducing peripheral neuropathy(especially tingling sensation and pain) but also in improving ability to sense the 10-g force monofilament. Conclusion: Even though self-foot reflexology was not effective in improving peripheral circulation, it had good effect on improving peripheral neuropathy. Therefore self-foot reflexology can be used as a nursing intervention program for promoting foot care for patients with DM patients.

이 논문의 목적은 혈액 순환 모형 기반 수업을 적용한 후에 11학년 학생들의 개념 변화를 다차원적 틀로 분석하는 것과 개념 이해를 향상시키기 위한 교수 전략에 대한 시사점을 찾아내는 것이다. 그 모형 기반 수업은 4차시로 구성되었다: (1) 혈액 순환에 관한 과학사를 적용하여 학생들의 흥미를 유도하는 도입 부분, (2) 쥐의 해부 실험, (3)심장의 자동 박동에 관한 비디오 자료, (4) 혈액 순환의 경로 모형 구성하기 활동. 사전 검사, 사후 검사, 면담 자료에 근거하여, 학생들의 혈액 순환 경로 모형을 구분하였고, 혈액 순환 개념에 관한 학생들의 존재론적 속성과 개념 지위를 조사하였다. 대부분의 학생들은 수업 후에 혈액 순환의 경로와 그 혈액 성분의 변화를 정확히 기술하였다. 그러나 그 모형 구성하기 활동은 심장에 연결된 각 기관으로의 혈류량 분배와 혈액과 조직세포 사이의 물질 교환 기작의 이해를 향상시키는데 충분하지 못했다. 면담에서 학생들이 언급한 개념 지위 요소 분석을 통해, 학생들의 개념 이해에 어떤 개념 지위 요소가 도움을 주는지, 잘못된 개념 지위 요소는 무엇인지, 잘 사용되지 않는 지위 요소는 무엇인지 등의 정보를 얻을 수 있었다. 또한 학생들의 각 개념 지위 획득은 혈액 순환 개념에 대한 어떤 존재론적 속성을 갖는가에 따라 달라짐을 발견하였다. 이런 연구 결과는 혈액 순환과 같은 평형 범주의 개념 변화률 촉진하기 위한 교수 전략을 고안하는데 도움을 줄 수 있을 것이다.

배경: 기존에 사용되고 있는 인공심폐기는 비박동성 펌프로 회로 내부에 형성되는 압력이 낮고 혈구 손상이 적어서 표준 인공 심폐기로 선호되고 있다. 그러나 많은 실험적 연구들을 보면 박동성 관류가 혈역학, 대사, 장기의 기능, 미세 순환에 대하여 비박동성 관류보다 유익함을 알 수 있다. 그러나 박동성 인공심폐기는 높은 회로 내부 압력과 혈구손상이 해결되어야 할 문제점으로 개발이 어려웠다. 이 연구의 목적은 국내에서 제작된 이중 박동성 인공심폐기의 안전성 및 유효성을 알아보는 것이다. 대상 및 방법: 6마리의 송아지를 대상으로 이중 박동성 인공 심폐기 실험을 하였으며, 완전체외순환을 시켰다. 체외순환은 상,하 대정맥과 대동맥 사이를 우회하였으며, 막형 산화기를 사용하여 혈액을 산화시켰다. 산화기는 좌우측 펌프 중간에 위치시켰다. 순환 시간은 4시간이었다. 동맥혈가스분석, 혈액검사, 혈장 유리 혈색소를 측정하였으며, 맥압과 회로 내부압력을 관찰하였다. 측정은 인공 심폐기 구동 전과 순환 1, 2, 3, 4시간째에 측정하였다. 결과: 동맥혈 가스분석상 pH, 이산화 탄소분압은 모두 정상 범위였으며, 동맥혈 산소 분압은 100 mmHg 이상의 충분한 산화를 보였다. 혈장 유리혈색소는 완전 체외순환하여 4시간이 경과하면서 15.87 $\pm$5.63 mg/㎗로 점차 증가소견을 보였으나 20 mg/㎗ 이내였다. 혈액검사소견상 뚜렷한 이상소견은 없었다. 순환전 수축기 혈압은 97.5$\pm$5.7 mmHg이었으며 시간 경과하여도 100 mmHg 이상의 혈압을 유지하였다. 확장기 혈압은 72.2$\pm$7.7 mmHg이었으며 시간 경과하여도 잘 유지되었다. 평균 혈압은 순환 전 83$\pm$9.2 mmHg이었으며, 시간 경과 시 증가된 소견을 보였다. 펌프의 유량은 3.3 L/min이상을 유지할 수 있었다. 완전체외순환 동안의 혈압의 변화를 보면 순환 전 심장과 유사한 동맥혈압을 보였다. 결론: 이중 박동 구조를 이용한 박동성 인공심폐기는 효과적인 박동성 혈류를 제공하면서 혈구 세포손상도 적었으며, 혈액학적 및 혈역학적인 면에서도 우수한 결과를 보였다. 따라서 모든 심장수술의 인공심폐기로 사용되어질 경우 말초장기에 생리적이고 안정적인 혈류를 공급할 수 있을 것으로 기대된다.

For the simulation of the blood flow in coronary artery, the system modeling of coronary hemodynamics is combined with CFD technique. The blood flow in coronary artery interacts with the global coronary circulation. Especially in case of the coronary artery with stenosis, the interaction plays an important role in the hemodynamics of the circulation. In this study we present a combined numerical approach using both the CFD technique for flow simulation and the global system model of coronary circulation. We use a lumped parameter model for the global simulation of coronary circulation whereas the finite element method is employed to compute the viscous flow field in stenosed coronary artery, The time variation of the pressure drop due to stenosis is obtained from the proposed numerical method. Numerical results shows that the flow resistance and pressure drop due to stenosis has a relatively large value in systole.

Insomnia is defined as an experience of inadequate or poor-quality sleeping habit, coupled with more than one of the following symptoms : having difficulty sleeping, waking up too early in the morning or not having sound sleep. Insomnia is one of the most common complications that stroke patients experience, which interfere the patients' recovery. The authors observed two improved cases of insomnia in stroke patients by administrating traditional Korean medicine. The patients suffered from insomnia with nocturnal irritation, constipation, petechia of the tongue, thready or weak pulse. These symptoms, were diagnosed as blood stasis and we administered Hyulboochucke-tang three times a day, to improve blood circulation to remove blood stasis. After the administration, nocturnal irritation disappeared and the insomnia improved. Based on this experience, it is considered that enhancing blood circulation to remove blood stasis can be applied to the treatment of insomnia that stroke patients suffer.

In this study, a basic research on artificial liver was performed for its application to people on the waiting list of liver transplant or patients with hepatic insufficiency. Artificial livers are generally classified into mechanic type, bioartificial type, and hybrid type. An extracorporeal circulation device was examined herein, which is indispensable in the application of an artificial liver, for its effectiveness in supporting the recovery of liver functions. Extracorporeal circulation system is a treatment and life-support system which sends out the patient's blood, removes toxicity by various methods, and then sends the blood back to the interior of the body. This study used an extracorporeal circulation system which enables the Plasma Perfusion by CVVH method, and applied the program of Bioateco corp. Animals with acute hepatic insufficiency were produced to apply the extracorporeal circulation device. As a result, their ammonia, bilirubin, SGOT, SGPT, and bile acid levels rose, confirming the liver function restoration in the experimental animals.

Object: Death rate due to hypertension, atherosclerosis, ischemic heart disease and cerebral infarction induced by Westernized diet and increased average life span is on the rise. Decrease in blood circulation, activation of thrombus generation and intravascular lipid accumulation, cited as the principal causes of the above mentioned diseases in recent studies, result in circulatory disturbance and blood vessel obstruction leading to ischemic cell death of heart, brain and peripheral vessels. Method: We investigated the biochemical changes in microvascular permeability, aggregation of platelet and the intravascular lipid accumulation in induced-diabetic rat using Streptozotocin. We also studied the effects of Woohwangcheongsirn-won after oral administration on blood circulation, platelet function and lipid metabolism. The results are as follows: I. Woohwangcheongsim-won increased blood circulation in microvessels. 2. Woohwangcheongsim-won increased the reduced erythrocyte deformability in diabetes. 3. Woohwangcheongsim-won induced the reduction of contents of 2, 3-DPG, but failed to affect the reduced contents of ATP in erythrocyte in diabetes. 4. Woohwangcheongsim-won reduced the activity of Ca/sup 2+/-ATPase in the membrane of erythrocyte. 5. Woohwangcheongsim-won reduced the platelet aggregation evoked by platelet agglutinin factor. 6. Woohwangcheongsim-won reduced the production of platelet-derived granules. 7. Woohwangcheongsim-won reduced the production of metabolites of arachidonic acid in diabetes, and also reduced the production of increased thromboxane B2. 8. Woohwangcheongsim-won reduced the synthesis of oxidized LDL-cholesterol. In conclusion, Woohwangcheongsim-won enhanced blood circulation in microvesseles, erythrocyte deformability and inhibited the increased platelet aggregation and the synthesis of oxidized LDL-cholesterol in diabetes. Therefore Woohwangcheongsim-won is believed to positively affect blood circulation (J Korean Oriental Med 2002;23(2):164-179)
