The oriental medicine based on the traditional Chinese medicine has developed characteristically according to the history and racial character respectively; China, Korea and Japan. Japan, among these nations, has accepted western medicine earlier than other nations and has tried to compare western and oriental medicine and combine them. In Japanese traditional medicine, it is characteristic that the old medical classics focusing on Sanghannon (傷寒論) and Geumgyeyoryak(金?要略) has developed The recent tendencies of clinical medicine and researches in Korean oriental medicine are mostly about the study of oriental medicine in view of western medicine and the combination of western and oriental medical treatment like Japan. But the study on the Japanese oriental medicine hasn't so far been tried before in Korea. From now on, we should not overlook that a more interest on Japanese oriental medicine will be very useful. Therefore we have surveyed the background of its origin and the process of development of the theory of ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$. What we wish to show in this paper is to provide a source for the basic understanding by explaining a fundamental theory of physiology and pathology of Japanese oriental medicine. Concepts of ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$ suggested by Nangai Yoshimashi in 1792 is the way of thinking that the circulation of 3 factors- ${\ulcorner}$Qi, Blood and Body Fluids${\lrcorner}$ nourish human body. Among these 3 factors, if Qi does not function smoothly, it causes the condition of a disease like Qi-deficiency, imbalance of Qi-distribution or Qi-depression and stasis; in Blood's case, deficiency of Blood and Blood stasis; and as for Body Fluids, stasis of Body Fluids. In the recent trend of study, there's a try to combining the western and oriental medicine, Qi is considered as psychoneurotic system, Blood as circulatory and endocrinologic system and Body Fluids as immunologic system.

Cyclosporine A(CsA) is a widely used immunosuppressant for transplant patients and is also used for the treatment of a wide variety of systemic diseases with immunologic disorders. However, its use is frequently limited because of complications such as nephrotoxicity or gingival hyperplasia. Although several hypotheses have been postulated for CsA-induced gingival hyperplasia, i.e. various cytokine effects of inflammatory cells, existence of plaque or CsA itself, but its pathogenesis is still unclear. For experimental chronic CsA toxicity, salt depletion has been shown to increased susceptibility of rodents to the effects of CsA, and this maneuver facilitates production of arteriolopathy and interstitial fibrosis in kidney that mimic the changes found in human. The purpose of this study was to evaluate pathogenesis of CsA-induced gingival hyperplasia by comparing changes between CsA administration groups of normal standard diet and those of low salt diet group. Specific pathogen-free, 20 to 25 days old(120 to 150 g), male Fisher-344 rats(KIST, Korea), 120 to 150g of body weight, were assigned to four groups of six animals each after one week of adaptation period for powder food. Group 1 received olive oil($300{\mu}l/g\;of\;diet$) with normal standard diet(0.4% of sodium)(NSD). Group 2 received CsA(Cypol-N, Jonggundang, Korea; $300{\mu}g/g\;of\;diet$) with normal standard diet(NSD+CsA). Group 3 received same amount of olive oil with low salt diet(0.05 % of sodium, Teklad Premier, U.S.A.)(LSD). Group 4 received same dose of CsA with low salt diet(LSD+CsA). Rats were pair fed and were sacrificed after six weeks. Renal histologic lesions associated with CsA, consisted of cortical interstitial fibrosis, tubular atrophy and hyalinization of arterioles and the impairment of renal function including increase of serum creatinine and decrease of glomerular filtration rate was more severe in low salt diet group. These were proved as the results of activated of renin-angiotensin system in the kidney by low salt condition. Meanwhile the degree of gingival hyperplasia at incisor and molar tooth was less severe in low salt diet group compared with normal sodium diet group. Hyperplastic gingiva showed mild epithelial hyperplasia and expanded underlyng stroma which consisted of matrix increasement, capillary proliferation and dilatation. While the number and the activation of fibroblasts were increased, inflammatory cells were rare in the stroma. The immunohistochemistry for TGF-${\beta}_1$ in the kidney and gingiva revealed stronger positive in LSD+CsA in kidney but in gingiva of NSD+CsA. These results suggested followings; Gingival hyperplasia can be developed without inflammatory cells infiltration and seemed not induced by CsA by itself. The major role for gingival hyperplasia by CsA would be the secondary effect of TGF-${\beta}$, which maybe upregulated by CsA administration. Low salt diet can attenuate this hyperplasia perhaps by decreasing the activation of $TGF-{\beta}$.

This study was undertaken to develop a reliable mice model demonstrating similar immunologic phenomena as human atopic dermatitis characterized with predominance of type-2 immune response. BALB/C mice and NC/Nga mice were sensitized twice with $100{\mu}l$ of 1% 2,4-dinitrochlorobenzene (DNCB) or vehicle (acetone : olive oil=4:1 mixture) in a week and challenged twice with $100{\mu}l$ of 0.2% DNCB or the vehicle at the following week. Mice were sacrificed at 19 days following the second DNCB or vehicle challenge for NC/Nga mice and at 28 days following the second DNCB or vehicle challenge for BALB/c mice. Upregulation of plasma 1gE, a hallmark of atopic dermatitis occurrence, was evident in the plasma obtained 4 day after the second DNCB challenge from BALB/c mice (approximately 4-fold) and NC/Nga mice (approximately 6-fold) treated with DNCB in comparison with that of the vehicle treated-control mice, and remain higher $3{\sim}4$ week after the second challenge. Ratio of plasma IgG1 versus IgG2a concentration was significantly higher in the mice treated with DNCB than the control mice, which also implies the skewed type-2 reactivity in vivo. Ratio of interleukin-4 versus interferon gamma produced in the splenic T cell culture supernatants was approximately 3-fold higher in the both strains of mice treated with DNCB than their control mice, respectively. The DNCB-treated mice demonstrated atopic dermatitis-like skin legions characterized with erythma, scaling, and hemorrhage, which was not observed with the control mice. Scratching on face or dorsal area was significantly more frequent (approximately 25-fold) in the DNCB-treated mice than the control at next day of the second DNCB challenge, and scratching frequency remains higher (approximately 4-fold) in the mice treated with DNCB than the control at 14 day following the second DNCB challenge. Overall, the mice model developed through sensitization and challenge with DNCB may be useful for research on atopic dermatitis and development of treatment materials for atopic dermatitis.

배경: 심장판막 및 그 주변의 큰 혈관들의 내피세포는 다른 부위와 달리 훨씬 완화된 면역 반응을 보이는 것에 착안하여, 고정액이나 면역학적 처치를 거치지 않은 이종 판막의 대동맥 판막의 임상적 유용성을 돼지-염소 간 이종 폐동맥 판막도관 이식 실험을 통해 알아보고자 하였다. 대상 및 방법: 돼지 폐동맥 판막도관은 특별한 면역학적 처치를 거치지 않은 채 준비하여 인공심폐기 가동 하에 염소의 우심실 유출로에 이식하였다. 염소들은 군당 2마리씩 배정하여 이식 후 하루, 1주, 3개월, 6개월, 12개월 동안 각각 관찰하였다. 실험동물을 희생하기 전 심초음파검사를 시행하여 판막의 움직임을 관찰하였고, 이종 장기를 적출한 후 판막도관의 조직학적 변화를 관찰하였다. 결과: 총 12마리 중 10마리에서 정해진 기간 동안 생존하였다. 이식된 폐동맥의 전벽의 동맥류가 12개월과 3개월 관찰한 각각 한 마리의 염소에서 발견되었다. 심초음파 검사에서는 다양한 정도의 폐동맥 판막 폐쇄부전의 소견을 보였으나 판막의 협착이나 혈전형성, 증식증은 관찰되지 않았다. 조직학적 관찰에서 이식 세포의 핵은 핵농축 및 핵융해를 통해 없어졌지만, 이식된 이종 판막도관의 세 구역(폐동맥, 폐동맥 판막, 누두부)은 구조가 보존되면서 점차적으로 시간에 따라 숙주 세포로 대체되었다. 결론: 면역학적 처리를 거치지 않은 이종 폐동맥 판막도관이 돼지-염소 간 이종 이식실험에서 다소의 문제점이 발견되기는 하였지만 성공적으로 숙주 세포로 대체되어 기존의 조직판막의 대안이 될 가능성을 제시하였다.

황색포도상구균은 사람에게서 염증을 동반한 다양한 형태의 국소적 또는 전신적 감염을 일으키는 주요 병원균이며, 황색포도상구균에서 풍부하게 발현되는 Staphylococcal protein A (SPA)는 염증의 활성화나 면역 반응의 회피와 관련된 균력인자로서 작용할 수 있다. 본 연구에서는 사람의 HaCaT 피부상피세포에서 재조합 SPA 단백질을 이용하여 염증반응에 대한 효과를 조사하기 위해서 pET-28a 발현벡터시스템을 이용하여 성공적으로 재조합 SPA 단백질을 제작하였고, 이 단백질(2 ${\mu}g$/ml)을 6, 12 및 24시간 처리한 HaCaT 피부상피세포에서 RT-PCR 및 ELISA를 이용하여 염증관련 부착인자 및 사이토카인의 발현을 분석하였다. SPA 처리 후 6시간에서 24시간까지 E-selectin, ICAM-1, MCP-1, IL-6 및 IL-8의 발현이 현저하게 증가함을 확인하였다. 또한 SPA는 HaCaT 피부상피세포에 대한 U937 단핵구의 부착력을 증진시켰다. 따라서, 본 연구의 결과는 SPA가 HaCaT 피부상피세포의 염증반응을 촉진시킨다는 사실을 보여주었으며, 황색포도상구균에 의한 피부염증질환에 있어서 중요한 병원성인자로서의 역할을 수행한다는 사실을 시사해준다.

과민성폐렴(hypersensitivity pneumonitis)은 기도를 통해 흡입된 항원물질이 세기관지와 폐포에 면역매개 염증병변을 일으켜 발생하는 간질성폐질환(interstitial lung disease)이다. 다양한 유기물질이 발생원인으로 작용할 수 있기에 환자의 흉부영상검사와 임상증상을 통해 과민성폐렴을 의심하고 직업 또는 주변 환경을 통해 노출되는 항원을 파악하는 것이 과민성폐렴 진단의 핵심이다. 하지만 다양한 임상증상과 진행 형태로 인해 간질성폐질환 환자의 진단에서 과민성폐렴을 정확히 감별할 수 있느냐는 풀기 쉽지 않은 주제이다. 이에 2020년 미국흉부학회, 일본호흡기학회 그리고 라틴아메리카흉부학회는 과민성폐렴 진단에 대한 새로운 임상진료지침을 발표하였다. 이번 임상진료지침은 과민성폐렴 진단에 있어서 흉부 고해상도 전산화단층촬영(high-resolution CT; 이하 HRCT)의 역할을 강조하며 과민성폐렴에 대한 새로운 분류 기준도 제시하고 있다. 본 종설은 흉부 HRCT 내용을 포함해 새롭게 소개된 과민성폐렴 진단에 대한 전반을 살펴보고자 한다.

Gu-Chang is a disorder characterized by recurring ulcers confined to the oral mucosa. Despite much clinical and research attention, the causes remain poorly understood. In this paper, we will compare Gu-Chang with Recurrent Aphthous Stomatitis(RAS) in order to know what is the similiarity between Gu-Chang and RAS. So we will arrange various oriental and western medical literatures which are important. As a result of arrangement of the causes, symptoms and therapys of Gu-Chang, we can conclude through the studies as follows. 1. The etiologies of Gu-chang are following. In the Sthenia syndrome, there are evil heat of external factor, heat of heart and spleen, insomnia, heat of upper warmer, stress and diet, heat of lung and heart, excessive heat of upper warmer, inappropriate food intake, heat conveyance of organ, heat of stomach merdian, moistured heat of spleen and stomach and stasis of liver energy. In the Asthenia syndrome, there are deficiency of stomach energy, deficiency of upper warmer leading to heat, deficiency of middle warmer leading to cold, deficiency of lower warmer leading to heat, deficiency of middle energy, deficiency of blood, decreased fire and deficiency of soil, yin fire of lower warmer, deficiency of heart yin, deficiency of spleen yin and deficiency of qi and blood. 2. In western medicine the causes of RAS is presumed as local, microbial, systemic, nutritional, genetic, immunologic factors. 3. Once Gu-chang is compared with RAS, in the deficiency of yin leading to hyperactivity of fire, deficiency of yin leading to floating of fire and stasis of liver energy, recurring of Gu-chang is similar to RAS. Although recurring of Gu-chang due to tripple warmer of excessive fire has no recurrance, since there are the degree of Pain, site of lesion, dysphagia etc, it is similar to major RAS. It is may be believed that Sthenia Gu-chang is similar to major RAS, shape of recurring, site of lesion, degrree of Pain and white color of Asthenia Gu-chang are similar to minor RAS, but there is no similarity concerning herpes RAS in the literatures that describe the symptoms. 4. Generally, the treatment of Gu-chang is divided into Asthenia and Sthenia Syndrome. The method of cure to Sthenia syndrome is heat cleaning and purge fire, Asthenia syndrome is nourish yin to lower and adverse rising energy and strength the middle warmer and benefit vital energy. 5. Following is the medication for Sthenia syndrome. Heat of heart and spleen is Do Jok San, Yang Gyek San, Juk Yup Suk Go Tang, evil heat of external factor is Yang Gyek San Ga Gam, Stasis of liver energy is Chong Wi Fae Dok Yum, moistured heat of spleen and stomach is Chong Gi Sam Syep Tang. The medication for Asthenia Syndrome is following. Deficiency of upper warmer leading to heat is Bo Jung Ik Gi Tang, deficiency of middle warmer leading to cold is Bu Ja Lee Jung Tang, deficiency of lower warmer leading to heat is Yuk Mi Ji Hwang Tang, deficiency of yin leading to hyperactivity of fire is Ji Baek Ji Hwang Hwan, deficiency of yin leading to floating of fire is Lee Jung Tang Ga Bu Ja Medicine for external use were Yang Suk San, Boo Wyen San, Rok Po San, Yoo Hwa San ate. 6. In western medicine, there is no specific treatment for RAS, and management strategies depend on dinical presentation and symptoms and includes antibiotics, oral rinses, glucocorticoids, immunomodulatory drugs, vitamines, analgesics, laser and antiviral agents.

목 적 : p16 유전자는 염색체 9p21에 위치하는데 종양억제 유전자 중 하나로 cyclin-dependent kinase의 억제제로 작용하며 Rb 인산화를 억제한다. 다양한 종류의 종양에서 p16 유전자의 결실 또는 과메틸화가 발견되고 있는데 이는 급성림프구성백혈병에서도 흔히 발견되는 이상 소견으로 높은 빈도로 나타나고 있지만 급성림프구성백혈병의 예후와 p16 유전자의 연관성에 대해서는 아직 논란의 여지가 있다. 본 연구에서는 면역조직화학염색으로 확인한 p16 단백질의 소실과 급성림프구성백혈병 환아들의 임상 경과와의 연관성에 대하여 조사하고자 하였다. 방 법 : 1998년 1월부터 2006년 12월까지 급성림프구성백혈병으로 진단된 74명의 진단 시 골수 슬라이드에서 p16 단백질 면역조직화학염색을 하였다. 환아들의 임상 양상, 검사실 소견, 치료 후 경과에 대해서 후향적으로 조사하였다. 결 과 : 74명 중 12명에서 p16 단백질이 면역화학염색 결과 음성이었다. 이들 중 남아가 7명 여아가 5명이었으며 진단 시 연령의 중앙값은 5.8(1.3-18.8)세였다. 백혈구 수의 중앙값은 17,225 $(500-403,300)/{\mu}L$ 이었으며 면역표현형은 early pre-B CALLA (+)형이 7명, T 세포형은 5명이었다. 진단 시 예후 중간군이었던 두 명의 환아들에서 골수 재발 하였으며 3명의 환아들이 유방암의 가족력이 있었다. 4명이 사망하여 8년 생존율은 $53.5{\pm}18.7%$였다. 결 론 : p16 단백질의 소실은 소아 급성림프구성백혈병에서 불량한 예후와 연관된 인자로 추정되며 임상에서 진단 시 p16에 대한 유전자 검사뿐만 아니라 단백질에 대해서도 검사가 필요할 것으로 생각된다. 하지만 좀더 많은 환자들에 대한 분석이 더 정확한 연관성을 밝히는데 도움이 될 것으로 사료된다.

Objective : Rheumatoid arthritis is an autoimmune disease that pathogenesis is not fully understood and one of the most intractable musculoskeletal diseases. The concern in the immunopathogenesis of rheumatoid arthritis has been increased since 1980's and many immunotherapeutic agents including disease-modifying antirheumatic drugs (DMARDs) were developed and became the mainstay of treatment of rheumatoid arthritis. However, the cure of the disease has hardly been achieved. In oriental medicine, rheumatoid arthritis is related to Bi-Zheng(痺證), that presents pain, swelling, andlor loss of joint function as major clinical manifestations, and also known to be deeply involved in suppression of immune function related to weakness of Jung-Ki(正氣). The herbal medicine, empirically used, could be a potential resource of development of new immunotherapeutic agents for rheumatoid arthritis. Methods : We developed a search strategy using terms to include "rheumatoid arthritis and herbal medicine" combined with "Chinese medicine" and/or "Oriental medicine". The search was focused on experimental studies of herbal medicine (January 1999 to May 2004), which is known to have effects on immune function of patients with rheumatoid arthritis. Computerized search used Internet databases including KISS and RISS4U (Korea), CNKI (China), MOMJ (Main Oriental Medicine Journal, Japan), and PubMed. The articles were selected from journals of universities or major research institutes. Results : The literature search for experimental studies on effects of herbal medicine on immunity of rheumatoid arthritis retrieved a total of 21 articles (Korea; 8, China ; 12, Japan ; 1). Of 21 articles, 10 were related to single-drug formula, 2 to drug interaction, and 9 to multi-drug formula. Single-drug formula was mainly used for aqua-acupuncture and researches on active components. Studies of drug interaction emphasized harmony of Ki-Hyul(氣血) and balance of Han-Yeul(寒熱). Multi-drug regimen was mainly found among formulas for Bo-Ki-Hyul(補氣血) and Bo-Sin(補腎). Conclusion : Studies on rheumatoid arthritis were performed both in vitro and in vivo in vitro study, LPS-stimulated splenocytes and synoviocytes were treated with herbal medicine, resulting in proliferation and activation of immune cells and suppression of cytokine activities in vivo study CIA animal model demonstrated that herbal medicine decreased antibody production and improved function of immune cells. In cellular and molecular study herbal medicine showed profound effects on the level of mRNA expression of certain cytokines related to immune function. This study revealed that herbal medicine has significant immune modulatory action and could be used for recovery of immune dysfunction of rheumatoid arthritis patients.
