  • Objective : One of the unique syndromes in Asian traditional medicine named 'heat entering the blood chamber(熱入血室, HEBC)' first appeared in Shanghanlun(傷寒論) and Jinguiyaolue(金匱要略) written by Zhangzhongjing(張仲景) who is the most famous doctor in ancient China. Method : Through comparison between Huangdineijing(黃帝內經), Shanghanlun(傷寒論), Jinguiyaolue(金匱要略) and other medical texts, the correct meaning, causes and mechanisms of HEBC can be analysed and organized to suggest new view of HEBC in modern society. Result : This syndrome is usually occurred in women during catching cold and menstruation, accompanying alternation of chillness and fever, pseudo-malaria, delirium, raveled chest(結胸), uterine hemorrhage, etc. The main sign of this syndrome, delirium belongs to the category of liver disease and fever in Huangdineijing(黃帝內經) which is a document more early published than Shanghanlun. Although there are still many other comprehensions about what blood chamber is, it could be the same as uterus according to Huangdineijing, it is relevant to the control of menstruation and emotions, and the function of liver and thoroughfare vessel(衝脈). Conclusion : HEBC is a syndrome exclusive to women, caused by their unique physical and psychological characteristics. It's beginning can be found in Huangdineijing, and by Shanghanlun and Jinguiyaolue, its concept as a single disease pattern becomes established. In other words, HEBC is a complex disease related to menstruation and its related hormonal dysfunctions, closely related to PMS, menopausal syndrome of today. Physical symptoms accompanied by psychological anxiety and fear is characteristic of this condition. Therefore gynecological approaches as well as socio-cultural issues related to women in modern society must be adopted when dealing with HEBC.

  • Our study is to review Chinese traditional medicine's journals about the diagnosis and treatment of spasmodic torticollis such as category, syndrome differentiation, acupoints of treatment, and herbal medicine. The journal search was performed using the search engine of China Academic Journal (CAJ) and China Doctor/Master's Dissertation (CDMD) in China National Knowledge Infrastructure (CNKI) from January 1982 to October 2012. Searching key words were the diverse combination of "spasmodic torticollis", "cervical dystonia", "Chinese traditonal medicine", "herbal medicine", "acupuncture", and "syndrome differentiation". The inclusion criteria was all kinds of journals including Chinese traditional medicine approach except for experiment study. The category, syndrome differentiation, acupoints of treatment, and herbal medicine from finally selected journals were extracted and summarized. The fourty-seven Chinese journals were selected finally. The category was divided into wind syndrome, trembling syndrome, convulsive syndrome, and convulsions. The syndrome differentiation was classified as internal stirring of liver wind, yin-blood depletion, invasion of external contraction, uncontrol of governor vessel, internal obstruction of phlegm turbidity, dual deficiency of qi and blood, and blood stasis due to qi stagnation. The combination of acupoints to unblock the meridian and dissipate binds and to tonify governor vessel and repel tremor was mainly used in acupuncture treatment. Galgun-tang or galgun-tanggami was primarily used and the others were the prescriptions to tonify liver and kidney, to calm convulsion, and to dispeling wind-phlegm. We suggests that spasmodic torticollis could be treated using Korean medicine's approach in Korea.

  • 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.

  • In oriental medicine, there is the fundamentals to lead a stirring life, and it is an important matter that make a study of fundamentals for treatment. The su-wen(素問) mentions the fundamentals of sheng(生之本), the fundamentals of qi(氣之本), the fundamentals of feng-cang(封藏之本), the fundamentals of ba-ji(罷極之本) and the fundamentals of cang-lin(倉廩之本). They are terminologies expressing physiological functions of the five viscera - heart, lungs, kidneys, liver and spleen. The five viscera are expressed through face, fur, hair, nail and lips. And the five viscera are closely connected with blood, skin, bone, muscle and flesh. Through the changes of personal appearance, we can recognize those of their internal organs. In oriental medicine, they are called as the cang-xiang(藏象). Heart is the fundamentals of sheng(生), and it is related to spirit, blood and blood vessel. Lungs are the fundamentals of qi(氣), because they master the extensive meaning of qi(氣). Kidneys are the fundamentals of feng-cang(封藏) which means seclusion. Liver is the fundamentals of ba-ji(罷極) that have several view by concept. Spleen, stomach, large and small intestines, paunch and bladder are the fundamentals of cang-lin(倉廩), that is to say, gastrointestinal tract that ingest diet and digest it.

  • 현대사회에 있어서 질병은 매우 다양하게 발견되고 있다. 또한 한번 발병하면 아니면 적절한 검진시기를 놓쳐 돌이킬 수 없는 상황을 접하게 되는 경우가 종종 있다. 사회가 발전하면서 과도한 비즈니스와 음주 흡연 등으로 우리의 간은 매우 피곤한 상태에 놓이게 되며 질병 발생율도 매우 높다. 여러 질병 중 특히 간에 관련된 질병은 회복이 불가하여 장기이식수술에 의존하는 편이다. 이와 관련하여 본 연구는 MDCT로 얻어진 영상을 3차원 영상 기법으로 간의 형상을 렌더링 하여 체적을 구하고 간 이식 수술시 혈관과의 분리 작업을 통해 절개 라인을 결정할 수 있도록 미리 시물레이션 할 수 있는 영상처리 기법을 개발하고자 간 영역 자동 추출 알고리즘을 적용하여 시물레이션 한 결과 수술을 용이하게 집도할 수 있도록 새로운 장을 열게 되었다.

  • Sprague-Dawley(SD) rats were orally administered with $N^G$-nitro-L-arginine methyl ester(L-NAME) which inhibits or blocks the production of nitric oxide from L-arginine in vascular endothelial cells and vessel tissue to statistically examine the effects of nitric oxide on some physiological changes such as blood pressure and heart rate, and to confirm the apoptosis induced by the suppressed nitric oxide activity in some related organs under light microscope. Systolic blood pressure significantly increased 28.5% by the chronic treatment of L-NAME for 8 weeks (P<0.001), no significant difference, however, was observed in heart rate between the control group and the L-NAME-treated group regardless of their age. Hematoxylin-eosin staining showed some histological alterations only in kidney among the examined organs; heart, liver, pancreas, and adrenal gland from the L-NAME-treated group. TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) test showed a strong positive reaction, representing that the chronic treatment of L-NAME facilitates apoptosis, in the cortex and medulla of kidney, but not any significance detectable in the other organs. These results conclude that chronic treatment of L-NAME significantly increases blood pressure, and that the followed inhibition of nitric oxide synthesis occurs a typical inducement of apoptosis in kidney.

  • This study was done to investigate the effect of Ganyangsanghang-bang(GYSHB) on hypertension. After administering GYSHB extract to SHR for 5 weeks, changes in blood pressure, pulse rate, aldosterone and catecholamine levels in plasma were examined, and immunohistochemical changes were observed, and liver function test was done. The following results were obtained; blood presure decreased significantly as well as levels of aldosterone and norepinephrine in SHR. But levels of dopamine were unaffected. No capillary vessel dilation in adrenal cortex was observed. Safety against hepatic toxicity was showed. These results support a role for GYSHB might be usefully applied in treatment of hypertension.
