ObjectivesThe aim of this study was to investigate anti-inflammatory activity of Mugi-hwan (MGH) Water Extract. MethodsCells were treated with 2 ug/ml of LPS 1 hour prior to the addition of MGH. Cell viability was measured by MTS assay. The production of NO was determined by reacting cultured medium with Griess reagent. The expression of COX-2, iNOS and MAPKs was investigated by Western blot, RT-PCR. The content of level of cytokines (PGE2, IL-6, in media from LPS-stimulated Raw 264.7 cells was analyed by ELISA kit. ResultsMGH inhibited the production of NO, PGE2, IL-6 as well as the expressions of iNOS, COX-2 in the murine macrophage, RAW 264.7 cells. MGH also had suppression effects of LPS induced MAPKs activation. ConclusionsThese results suggest that MGH has an anti-inflammatory therapeutic potential, which may result from inhibition of MAPK phosphorylation, thereby decreasing the expression of pro-inflammatory genes.

Objectives :Sodok-eum(xiaodu-yˇln, SDU) exhibits potent anti-inflammatory activity with an unknown mechanism. The purpose of this study is to elucidate the molecular mechanisms of SDU on pharmacological and biochemical actions in inflammation. Methods :We examined the effect of SDU on pro-inflammatory mediators in lipopolysaccharide(UVB)-stimulated HaCaT. The investigation focused on whether SDU inhibited cyclooxygenase-2(COX-2), interleukin-6(IL-6), interleukin-8(IL-8) and mitogen-activated protein kinases(MAPKs) in UVB-stimulated HaCaT cells. Results :SDU inhibited UVB-induced IL-6, IL-8 productions as well as the expressions of COX-2. Furthermore, SDU suppressed the UVB-induced phosphorylation of extracellular signal-regulated kinase 1/2(ERK1/2), c-JUN N-terminal kinase 1/2(JNK 1/2), p38. Conclusions :These results suggest that SDU has inhibitory effects on UVB-induced IL-6, IL-8 production, as well as the expressions of COX-2 in the HaCaT. The inhibitory effects occur through blockades on the phosphorylation of MAPKs following activation.

Objectives This study was carried out to find the effects of Gami-cheongyulsaseub-tang (hereinafter referred to GCST) on the inhibition of zymosan-induced pain in rats and collagen II-induced arthritis (CIA) in DBA/1J mouse. Methods As an acute inflammatory pain model, peripheral inflammation was induced by intraplantar injection of zymosan into the right hind paw in rats and then the hyperalgesia and pain regulating factors in spinal cord were analyzed. As a chronic inflammation model, the mixture of collagen II and complete Freund``s adjuvant was treated into mice to establish rheumatoid arthritis and then body weight, thickness of hind paw, pathological change of spleen, immunological rheumatoid factor (IgG1, IgG2a, IgG2b, IgM and anti-collagen II), pro-inflammatory cytokines, and bone injury were analyzed. Results In the acute inflammatory pain model, GCST significantly inhibited the thermal and mechanical hyperalgesia and the pain regulating factors, including Fos, CD11b, PKA and PKC, in the spinal cord with a dose-dependent manner. In the chronic rheumatoid arthritis model, GCST administration decreased arthritic index and paw edema as compared with CIA control group. In particular, GCST reduced significantly the serum levels of total IgG2a, IgG2b, IgM, and specific anti-collagen II, but not total IgG1. GCST also resulted in the attenuation of bone injury and spleen enlargement/adhesion in CIA mice. Moreover, the secretion of pro-inflammatory cytokines TNF-α and IL-1β in CIA mice was significantly reduced by GCST in a dose-dependent manner. Conclusions Comparison of the results in this study showed that GCST had anti-nociceptive and immunomodulatory effects. These data imply that GCST can be used as an effective drug for not only rheumatoid arthritic pain but also other auto-immune diseases. (J Korean Med Rehab 2015;25(1):27-44)

Objectives In this study, we investigated the inhibitory effects of Samhwangsasim-tang (S.H) on the allergic response caused by ovalbumin(OVA) sensitization and challenge in BALB/c mice. Methods The experimental animals were divided into five groups; 1) normal as negative control, 2) OVA-sensitized mice, 3) OVA-sensitized mice treated with 200 mg/kg of S.H 200, 4) OVA-sensitized mice treated with 400 mg/kg of S.H 400, and 5) OVA-sensitized mice treated with 5 mg/kg of Dexamethasone (Dex). Antigen sensitization for allergic mouse model was performed with twice injection of OVA for 2 weeks. After secondary injection, S.H was administrated orally into mice every day for 13 days and the inhibitory effect of S.H on allergic responses was evaluated. Results Treatment of S.H into allergic mice reduced significantly ear edema and infiltration of immune cells in ear tissues induced with OVA challenge in a dose-dependent manner. S.H reduced significantly the serum levels of Total Immunoglobulin(Ig)G and IgE, and particularly inhibited the production of OVA-specific IgE, but not OVA-specific IgG. The serum level of proinflammatory cytokine TNF-α and Th2-associated cytokine IL-4 also were significantly decreased by S.H adminstration in a dose denpendent manner. S.H attenuated OVA-induced secretion of IFN-γ, but not IL-12 which is a cytokine inducing the development of Th1 cells. It also reduced significantly the secretion of IL-4, which is a cytokine inducing the development of Th2 cells, after splenocytes were stimulated with OVA. However the secretion of IL-5 and IL-13 was influenced weakly or a little. Conclusions These results indicate that S.H could reduce the allergic response through inhibition of antigen-specific IgE and Th2-inducing cytokines. It suggest that S.H may be available clinically for the treatment of allergic patients. (J Korean Med Rehab 2014;24(3): 71-85)

선전과 소통 : 루치아노 발데사리의 브레다 전시관 계획에 관한 고찰 1951-1963

Main theme of this paper is the evaluation of the historical significance of Luciano Baldessari's exhibition works mainly during the Fifties. In order to understand the formal and logical basis of those project, his relationship with the historical Avant-gardes and the consequences expressed in his pavilion projects for the Breda Industrial Company are analyzed. The first part focuses on the influence of Italian Futurism, German Expressionism and Italian Rationalism on the formation and experience of Baldessari during the interwar years. The encounter with these movements determine the interest but also the principles along which Baldessari represents his idea of object, space and place. Specially his professional activities during Fascism would determine his attitude toward political power and the necessity of autonomy in artistic sphere. In the second part, different themes that Baldessari affronted in each project of Breda Pavilions is analyzed. Another important issue regard the historiography of the contemporary architecture. Often, many important works that lies in the threshold of the disciplines such as painting and sculpture and media art were excluded in the history of architecture just because they do not deal with the architectural object. Recently, many elements such as theatrical project and temporary objects are considered as part of urban reality and architecture with acknowledgment of their capacity to create event and situations. Along this thought, not just the reconfiguration on the territory of architecture in present but also the criterion to evaluate the past history of architecture is changing drastically. This study on the pavilions of Baldessari intends to contribute indirectly on the current issue of dominion of architecture, but also to evaluate objectively recent architecture. Consequently, architectural protagonists such as Baldessari and their ephemeral projects would be evaluated compressively in their multiplicity of significance.

This research focuses on the role of Giovanni Marinioni during the formation of the modern cartography and cadastre during the 18th century. Initial study began with Giambattista Nolli's Roman map noticing not much information was available to acknowledge his activities during his Milan period before the departure to Rome. It became evident that Marinoni was a key person to understand the complex circumstances in which the professional training and formation of Giambattista Nolli took place as later worked as an anonymous intern during the elaboration of Theresian Cadastre of Milan. The other important figures are Leandro Anguissola and Giovanni Filippini. Anguissola's position and precedent work facilitated Marinoni's multidisciplinary activities that he had performed in Vienna and Milano in the field of making urban maps of those two cities. On the other hand, Filippini not only collaborated with Marinoni but also introduced Nolli in the field of cartography. These activities show transitional and dual aspects that characterized the period in which important irreversible changes that occur during the reign of Habsburg empire and in the rest of the Europe toward the formation of modern society and state. Marinoni's theories and praxis greatly influenced Nolli's later commitment under the Savoia and later on the elaboration of the 'Pianta Grande di Roma' in 1748.

Public housing problem became a major issue in each European country during the period of the reconstruction. This study focuses on the one of the major institutional policies in the public housing sectors in Europe during the second postwar period, specifically the INA (Istituto Nazionale delle Assicurazioni)-Casa in Italy from 1949 to 1963. Thanks to the financial Aid provided by 'Marshall Plan' of United States government, Italy initiated INA-Casa housing program elaborated and realized by minister of Labour, Amintore Fanfani. He was strongly influenced by catholic socialism and Weberian corporatism, and also had previously written theoretical studies on the subject during the Interwar years. The outcome of this policy had been devaluated for its Keynesian aspect as well as vernacular predominance in the architectural forms. On the contrary, this study focuses on themes such as continuity of politics before and after the Liberation, status of the architects and their will to social engagement, notion of quarter as 'self-sufficient community' and 'residential unit'. These factors will allow to comprehend the complex nature of the reality where different categories were involved to resolve the common housing problem.

This study aims to analyse the method and strategy of spatial composition in the selective works of Italian architect Carlo Mollino. With the continuos renovation of the interpretative frames and method on modernity and in particular on the spatial phenomenon, works of Mollino, once disregarded by the historiography and evaluated for its peculiarity. emerge as important architectural phenomenons. The intrinsic value in his works also enable to comprehend the complexity and multiplicity of modernity in contemporary architecture. In order to achieve this preposition, six important works were analyzed with three key words, to understand comprehensively the process and the significance of each work and Mollino's contribution in the spatial composition of domestic and public spaces. Evaluation of the spatial strategies in conceptual investigations of Mollino had been underestimated to the relative poor conservation or incomprehension of various work, excluded from the categories of architectural elaborations. This study also aims to contribute, in the broad sense, the dialectical significance of modernity by emphasizing the aspects of his work related with Surrealism and vernacular tradition, as well as with its relationship with the various spatial dispositives.

본 연구에서는 합성보존제로 흔히 쓰이는 메칠파라벤과 방부효능을 가지는 천연추출성분인 p-아니식애 씨드를 HPLC를 통해 분리분석 하는 방법을 개발하였다. 메칠파라벤과 p-아니식애씨드는 같은 분자량(152.15g/mol)과 비슷한 구조, 같은 최대흡수파장(250 nm)을 보이기 때문에 HPLC로 분석 시 동일한 RT값(13.3 min)을 갖는다. 본 연구 저자들은 아세틸화 반응을 통해 메칠파라벤을 선택적으로 유도체화 한 후 C18 컬럼을 통해 분석했을 때 두 물질이 분리됨을 확인하였다. 아세틸화반응을 거치면서 메칠파라벤의 피크유지시간이 13.3 min에서 23.9 min으로 이동하였으며, 평균값은 23.9 ± 0.1 min, 피크면적 값은 5042882 ± 4778로 일정하게 나타났다. 또한 직선성의 평가에서 결정계수값은 0.9999658로 1에 가까운 값을 보였다. 시료의 검출한계는 1.47 μg/mL이었고 정량한계는 4.44 μg/mL이었다. 결론적으로 본 연구를 통해 개발된 분석법은 화장품 분야에서 유사한 구조를 가진 보존제 분석에 유용하게 사용될 수 있을 것으로 기대된다. In this study, we developed a HPLC method for the separation and analysis of methylparaben and p-anisic acid, which are commonly used as a synthetic preservative and natural preservative, respectively. Methylparaben and p-anisic acid have same molecular weight (152.15 g/mol), similar structure and same maximum absorption wavelength (250 nm), thus they showed same retention time (RT) value (13.3 min) in HPLC experiment. We observed that two substances are separated on C18 column after methylparaben was derivatized selectively through the acetylation reaction. Instead, RT of the acetylated methylparaben was moved to 23.9 min from 13.3 min. The average retention time was 23.9 ± 0.1 min and peak area values was 5042882 ± 4778. In addition it showed a high linearity in the calibration curve with a correlation coefficient (R²) of 0.9999658. Detection and quantitation limits were 1.47 μg/mL and 4.44 μg/mL, respectively. In conclusion, the developed method can be useful for separation and analysis of preservatives with similar structure in cosmetic fields.
