  • The object of this study was to obtain acute information (single oral dose toxicity) of Taraxaci Herba (Dried total parts of Taraxacum platycarpum. H.Dahlstedt (Compositae)), has been traditionally used in Korean medicine for treating various inflammatory diseases. In order to observe the 50% lethal dose (LD 50), approximate lethal dosage (ALD) and target organs, test articles were once orally administered to female and male ICR mice at dose levels of 2,000, 1,000, 500 mg/kg according to the recommendation of Korea Food and Drug Administration Guidelines. The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after single oral treatment of Taraxaci Herba aqueous extracts according to KFDA Guidelines with organ weights and histopathological observations of 12 types of principle organs. After single oral treatment of Taraxaci Herba aqueous extracts, we could not find any mortality and toxicological evidences up to 2,000 mg/kg treated group, the limited dosages in rodents at body and organ weights, clinical signs, gross and histopathological observations. Except for slight soft feces, which were detected in male mice treated with 2,000 mg/kg of Taraxaci Herba aqueous extracts at 1 day after end of treatment. The results obtained in this study suggest that the LD 50 and ALD of Taraxaci Herba aqueous extracts in both female and male mice after single oral treatment were considered as over 2,000 mg/kg because no mortalities were detected up to 2000 mg/kg that was the highest dose recommended by KFDA and OECD. However, it also observed that the possibility of digestive disorders, like diarrhea when administered over 2,000 mg/kg of Taraxaci Herba aqueous extracts in the present study, but these possibilities of digestive disorders can be disregard in clinical use because they ate transient in the highest dosages male only.

  • The purpose of this study is to investigate clinical frequency and priority of five pattern identification settled by Korean Standard Differentiation of the Symptoms and Sign for Stroke. The present study was done over 177 hospitalized patient with stroke in the Daejeon University Oriental Medical Hospital in the period of November 2006 to July 2007. Stroke patients had been interviewed by residents and specialists who studied standard operation procedures in Fundamental study for Standardization and Objectification of Differentiation and Pattern Identification of Syndrome of Oriental Medicine for Stroke. In Heat-transformation pattern group, men showed significantly high frequency and in Deficiency of Gi pattern group, women showed significantly high frequency. In Heat-transformation pattern group, the indicators such as 'aversion to heat during fever', 'flushed face', 'full and rapid pulse', 'dryness of the eyes, 'yellow coating of the tongue', 'feverishness of the limbs', 'dryness of the eyes' showed significantly high frequency. In Dampphlegm syndrome group, the indicators such as 'white coating of the tongue', 'yellowish face', 'thick coating of the tongue', 'wheezing in the throat with sputum', 'swollen tongue', 'slippery pulse' showed significantly high frequency. In Deficiency of Gi pattern group, the indicators such as 'pale tongue', 'lassitude', 'pale face', 'weakness pulse' showed significantly high frequency. In Deficiency of Eum group, the indicators such as 'short and rapid pulse', 'mirror-like tongue' showed significantly high frequency. For more sensitive Korean Standard Differentiation of the Symptoms and Signs for Stroke, Large scale study is to be done, giving weight on the important indicators.

  • Through this literal study, we have endeavored to provide korea's unique nursing intervention methods based upon Lee Je-Ma's Sasang Constitutional Theory which is a unique korean medical science. The Sasang Constitution Theory lay great emphasis upon health caring medicine to promote health according to self Constitution at normal times, preventive medicine to manage byself body and mind in everyday life, and eventually, ethical medicine to love benevolence and kindness but to dislike jealousy.A variety of methods has been introduced to diagnose a person's Constitution. And yet, appearance, mind and pathological signs are three major criteria. In appearance, comprehensive features such as figure (the shape of the human body), countenance, behavior, mood, and posture are observed. In mind, nature (character), talent, steadiness, personality, and greed are investigated. In pathological signs, physiological conditions when healthy and peculiar symptoms when being ill are diagnosed. By these three criteria, each Constitution is categorised into Taiyang Person, Soyang Person, Taieum Person or Soeum Person. Different healthcaring methods exist for each Constitution such as mind and body healthcaring, diet healthcaring, knowledge and behaviour leathering, age group healthcaring, regional healthcaring, social life hralthcaring, everyday life healthcaring, and materia medication healthcaring. An independent and unique healthcaring method for each person according to self Constitution could be an important nursing intervention strategy, and can product a new nursing theory. To enjoy longevity by inducing positive caring methods, I believe that individual nursing may be the most desirable nursing approach. Lee Je-Ma's Sasang Constitution caring method is not only a general nursing theory but also expected to be an important landmark/milestone/factor in Korean nursing, preventive nursing, developing new nursing intervention methods and forming new nursing theories. Therefore, it is required to conduct thorough, practical and theoretical researches in the field of nursing.

  • This study is aimed to test physiological and hematological actions of Rheum palmatum through clinical pilot study optimized for usual oriental medicine prescription. Thirty-one cases were finally collected and the sample extract 100 $m{\ell}$ of Rheum palmatum (ERP) was administered two times in a day during 3 days and checked with blood CBC test, urinalysis, liver function test, abdominal X-ray as well as general diagnostic process of oriental medicine; pattern identification, assessment of shapes and constitution. The total toxic effective rate of ERP was 9.68% in 3 cases of the whole in case of consistent uneasy state in the subjective symptomatic assessment and aggravation of blood and urine examination. The relevant diagnostic factors were so-eum constitution and essence type subject, carapaces species, lung type in the aspect of Jisan shape theory. On the other hand, the positive effective rate of ERP was 29.03% manifesting improvement of vital signs or present illness and no abnormal changes of blood chemistry and urinalysis and simple abdomen radiology. The relevant diagnostic factors were tae-eum constitution, energy type subject, aves species, heart and liver type in Jisan's shape theory. And the other cases were manifesting no specific change through the administration of ERP. The ratio of the numbers of decrease and increase was 44:5 in the tenderness and hardness of abdominal palpation. But if the pattern identification doesn't comply with the aim of rhubarb application despite of constipation and abdominal pain, the tendeness and biochemical report was shown in abnormal change. The mean number of diarrhea by ERP was $16.77{\pm}6.95$ during 3 days after administration, and the frequent areas of abdominal pain were lower>middle>upper in order, and it meant the target site of ERP too. Besides, the toxic reaction against ERP was expressed highly in case of decrease in blood cell count and hemoglobin, hematocrit having blood deficiency syndrome. Likewise, the toxicity of ERP was influenced by pattern identification manifesting present disease condition and diagnostic factors of four constitutions, Jisan's shape theory collaterally. In conclusion, evaluation of herbal toxicity in order for using as a clinical guideline, various diagnostic pattern information and shape features like the above should be studied together with other pharmacologic toxicology test for the future.

  • 인간의 감성은 주관적이고 개인적이며, 직관적이고 모호한 것이어서 정의하기도 힘들고, 따라서 측정하기는 더욱 어려운 과제이다. 일반적으로 감성의 측정방법은 사용자의 주관적인 평가를 토대로 하는 심리적 측정방법과 생리신호를 이용하는 생리적 측정방법으로 크게 나눌 수 있다. 하지만 이 두 가지방법 모두 한계를 가지고 있다. 따라서 본 연구에서는 디자인분야에서 접근이 용이하고 자연스러운 환경 하에서 사용자의 감성을 측정할 수 있는 방법을 제안하였다. 우선 사용자가 제품을 사용하는 도중에 유발되는 인간의 감성변화를 나타낼 수 있는 감성어휘들과 대표감성들을 추출하여 제품을 사용하는 도중에 표출되는 사용자의 감성을 측정하기에 적합한 주관적 평가스케일을 도출하였다. 이를 통해 심리적 측정방법의 한계점을 보완하여 제품을 사용하면서 표출되는 사용자의 감성을 효과적으로 측정할 수 있는 도구를 개발하였다. 개발된 소프트웨어(Video TAME)의 실험 진행 모듈에서는 실험 참여자가 실험실에서 자신이 태스크를 수행하였던 장면을 녹화한 동영상을 직접 재생해 보면서 자신의 감성변화를 평가할 수 있다. 실험 분석 모듈에서는 연구자가 각 태스크별로 전체적인 실험 내용을 재생하면서 실험 결과를 확인할 수 있고, 마이크로소프트 엑셀로 내보내기 위하여 다양한 측면에서 자료를 분석할 수 있다. 본 연구를 통해 개발된 도구는 제품을 사용하면서 자연스럽게 표출되는 사용자의 감성을 효과적으로 측정하기 위한 도구로 활용할 수 있을 것이다.

  • Adipocytes are endocrine cells that release bioactive mediators called adipokines. In condition of obesity characterized by low-grade chronic inflammation, adipocytes release inflammatory adipokines, which is related to insulin resistance. Bojungchiseub-tang (BJCST) has been used in symptoms and signs of edema, dampness-phlegm, kidney failure, and so on in Korean medicine. BJCST is also expected to have anti-obesity activities. In the present study, we examined whether BJCST modulate the production of inflammatory adipokines and the activations of the mitogen-activated protein kinases (MAPK) signaling pathway related to induce adipocyte inflammation to elucidate the effects and its mechanism of BJCST on lowering the content of inflammatory adipokines in 3T3-L1 adipocytes. As a result, BJCST suppressed the production of proinflammatory cytokines, tumor necrosis factor (TNF) $-{\alpha}$, interleukin (IL) $-1{\beta}$, IL-6, interferon (IFN) -${\gamma}$, granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), and the production of other inflammatory mediators, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO)viadownregulationofcyclooxygenase-2(COX-2)andinducible NO synthase (iNOS) gene expressions. In addition, BJCST decreased the phosphorylation of MAPK that promotes the production of inflammatory adipokines in 3T3-L1 mature adipocytes. In conclusion, BJCST could regulate the production of inflammatory adipokines and MAPK signaling pathway related to induction of adipose inflammation.

  • Dongmugong(東武公) advanced seven-feeling theory of Danguea(丹溪) and spirit-action theory of Buddhism. Sasang Constitutional Medicine has big three ideological base; phylosophy of the human nature, natural laws and the doctrines of Wangyangming(王陽明). In Dongyuisusebowon(東醫壽世保元), it is insisted that one's nature(性) and feelings(情) influenced to change his or her external form and the function of the internal organs. According to Dongyuisusebowon, the metabolism of human body is influenced by the actions of the nature(性) and the feelings(情). Also, sometimes, people get sick because of the disharmony of them. Of course, the concept of the nature(性) and the feelings(情) is different from a general idea. In Dongyuisusebowon, the nature(性) is made up of the intelligence(智), the courtesy(禮), the integrity(義), and the affection(仁). It is same with the feelings(情). The feelings(情), according to Sasang Constitutional Medicine, is composed of grief(哀), anger(怒), pleasure(喜), and enjoyment(樂). Dongmugong explained those in his writings and we got to know that the physiology and pathology of Sasang Constitutional Medicine could be explained by the interactions of twelve elements of the earth(十二地支). Symptoms and signs in his books can be explained by the same mechanism in Sanghanlon(傷寒論), but these of each constitution could be seen different one because of the different characteristics of Sasangin(四象人)

  • This study was carried out to determine the effect of $-6^{\circ}$ head-down bedrest on the cardiovascular and hormonal responses to orthostasis and to evaluate the mechanism of orthostatic intolerance. Ten healthy young men were changed the body position from $-6^{\circ}$ head-down or supine bedrest for 2 hr to $70^{\circ}$ head-up tilt for 20 min. During the bedrest, there were no differences in hemodynamic and hormonal changes between the head-down and the supine positions. However, the tendency of decreased end-diastolic volume and increased cardiac contractility during the later period of 2 hr showed that the cardiovascular adaptation could be accelerated within a relatively short period in the head-down bedrest. During the head-up tilt, presyncopal signs were developed in five subjects of the supine bedrest, and one of the same subjects of the head-down bedrest. In the tolerant subjects, the increase in cardiac contractility and plasma epinephrine level during the bend-up tilt was greater following the head-down bedrest than that following the supine bedrest to compensate for reduced venous return. The intolerant subjects showed the greater decrease in end-diastolic and stroke volume, and the greater increase in heart rate during the head-up tilt than the tolerant subjects. Cardiac contractility and plasma epinephrine level were remarkably increased. However, arterial pressure was not maintained at the level for the appropriate compensation of the reduced venous return. It seems that the tolerance to orthostasis is more effective after the short-term head-down bedrest than after the supine bedrest, and the secretion of epinephrine induces the higher cardiac performance as a compensatory mechanism fur the reduced venous return during the orthostasis following the head-down bedrest than the supine bedrest.

  • The aim of this study was to investigate the apoptotic effect and its mechanism on Radix Paeoniae Alba Extract(RPAE) in DU145 human prostate cancer cell line. RPAE induced apoptosis in a dose-dependent manner in DU145 cells as confirmed by both discontinuous DNA fragmentation using Hoechst33342 staining and poly-(ADP-ribose) polymerase(PARP) cleavage, which are apoptotic signs. To clarify the mechanisms on RPAE-induced apoptosis, we examined the p50(NF-κB subunit), IκBα, PTEN and Par-4 protein expression using Western blotting. Treatment with RPAE resulted in the decrease of p50 expression by IκBα increase, which resulted in Par-4 increase and bcl-2 decrease in DU145 cells. These results suggest that apoptosis of DU145 cells by RPAE involved decreases of NF-κB activation and bcl-2 expression, increase of Par-4 protein expression.
