Purpose: The purpose of this study was to investigate induction of cytokine expression in human gingival fibroblasts (HGFs) by whole cell and the components of T. forsythia. Material and Methods: After HGFs were treated with lipopolysaccharide (LPS), membrane protein isolated from T. forsythia or culture media of T. forsythia, the induction of interleukin (IL)-1, IL-6 and IL-8 was examined with real-time PCR and ELISA. Their induction ability of cytokines was compared with whole bacteria. Result: The expression of IL-6 and IL-8 was significantly induced in HGFs by whole bacteria and membrane protein. The expression of IL-$1{\beta}$ was induced by membrane protein of T. forsythia, not by whole bacteria. LPS and condition media of T. forsythia slightly activated HGFs. Conclusion: The membrane protein of T. forsythia could be one of virulence factors.

May 21, 2009. The 'Case of grandma Kim' that was highlighted as an issue in Korea. It led to the result that recognized initially in Korea about death with dignity. Since the initial sentence that recognized the death with dignity by the Supreme Court, It was actively discussed by configure the related social council and activities or Taking the initiative by Shin sang jin. But it couldn't draw a conclusion by religious community, the medical profession and related legal system etc. However, recently, the try are showing again. Nowadays discussions and interests about death with dignity are increasing gradually to government and whole of society. Therefore, examine the each countries opposing discussion. And should be sought reasonable solutions for its admissibility and validity. And to prepare the related legislation, review all the matters to National Bioethics Committee and in charge of the advice and decision about family. And if they can control the process of treatment interruption through the Commission. Then, it will be able to achieve the social consensus about the basis of treatment's discontinuation and will be able to escape from present practice that made by agreement between the family and the individual physician under the unclear standard. The decision of the judgment between 'unrecoverable patients' and 'terminal patients' is the decision of the judgment between 'unrecoverable patients' and 'terminal patients' is including the clear procedures that be the basis of judgment for medical standards of judgment. Also, may be considered the ways that participation of at least two or more doctors. The unrecoverable patients, they do not have the opportunity to express their free opinions. So, substitute for specific others and need to consider the agent's consent. In this case, the legal controversy arises which is the agent's decision about life and the patients' own decision are same. In order to overcome this, the preparation of the legal basis is essential about agree on the consent of agents.

<목적> Probiotics는 살아있는 organism으로서 사람이 복용하였을 때 건강에 이로운 효과를 나타내는 것을 말하며, 최근 염증성장질환의 치료에 있어서 probiotics의 효과에 대해 많은 연구가 이루어지고 있다. 살아있는 비병원성 Salmonella 균주를 이용한 연구 보고에 의하면, 대장암 세포주에 염증성 자극 후 인산화된 I-κBα의 ubiquitination을 이 균주가 억제하여 염증반응을 억제한다고 하였다. 하지만 이러한 항염증 기전

위장관 ; Lipopolysaccharide로 유도된 HT-29 세포주의 염증에서 Lactobacillus rhamnosus GG의 항염증 작용과 기전

Background/Aims: Probiotics are live non-pathogenic organisms that belong to the resident microflora, and confer health benefits by multiple mechanisms. Lactobacillus rhamnosus GG (LGG) is one of the probiotic bacteria that ameliorates intestinal injury and inflammation caused by various stimuli. We aimed to evaluate the anti-inflammatory effect and mechanism of LGG in lipopolysaccharide (LPS)-stimulated HT-29 cells. Methods: HT-29 cells were stimulated with interleukin (IL)-1β (2 ng/mL), tumor necrosis factor (TNF)-α (20 ng/mL), and LPS (20 μg/mL) in the presence or absence of LGG (107-109 colony forming units/mL). Production of the pro-inflammatory chemokine IL-8 was measured by ELISA and semi-quantitative PCR. Transcriptional activity of NF-κB-responsive gene was evaluated by luciferase assay with reporter gene. Toll-like receptor 4 (TLR4) mRNA expression was assessed by semi-quantitative PCR. The IκBα degradation was evaluated by western blot and intranuclear translocation of NF-κB was determined by western blot and immunofluorescence. Results: LGG did not affect the viability of HT-29 cells. Pretreatment of HT-29 cells with LGG significantly blocked TNF-α, and LPS induced IL-8 activation at both mRNA and protein level (p<0.05). Pretreatment of HT-29 cells with LGG attenuated LPS-induced NF-κB nuclear translocation and also blocked LPS-induced IκBα degradation. LGG also down-regulated TLR4 mRNA activated by LPS. Conclusions: LGG attenuates LPS induced inflammation, and this may be associated with TLR4/NF-κB down-regulation. (Korean J Gastroenterol 2012;60:86-93)

자원 고갈로 인한 에너지 부족과 온실가스 방출량 증가에 기인한 기후변화 등의 환경문제가 인류에게 현실적인 위협으로 등장함에 따라, 이에 대한 대응으로 전세계가 IT의 역할과 가능성에 주목하고 있다. 우리나라를 포함한 구미 선진국들은 환경과 IT의 전략적 융합을 통한 그린 IT를 저탄소 녹색성장을 위한 신성장 동력으로 인식하고, 저탄소 사회로의 전환 촉진을 위하여 정부 차원의 정책을 도모하고 있다. 본고에서는 그린 IT의 전략적 추진에 있어서 그린화의 인프라 핵심 기술인 에너지 절감형 그린 네트워크 기술의 전반적인 동향을 살펴본다.

This paper presents the photonic bandgap structure that has a defect mode within a broad stopband. In order to create a broad stopband, we eliminated one of periodic stopbands of PBG structure by using a quarter-wavelength transformer and cascaded another PBG structure having a center frequency corresponding to the eliminated stopband. We have demonstrated that it is a simple and effective method that can solve an overlapping problem of periodic stopband in two cascaded PBG structures.

Cellulase producing microorganisms, GPC-1, GPC-2, GNR-1 GNR-2, and GNR-3, were screened from the Rumen fluid of Korean Native Cattle. Isolated GPC-1 and GPC-2 were identified as Ruminococcus sp. according to results of the Gram stain and anaerobic characteristics. Based on morphological and physicochemical identification, the isolate GPC-1 and GPC-2 were identified as strains of Ruminococcus albus and Ruminococcus flavefaciens, respectively. Isolated GNR-1 GNR-2 and GNR-3 were identified as Bacteroides sp., Butyrivibrio sp. and Clostridium sp. according to results of the Gram stain, $H_2S$ producition and spore formation, respectively. Based on morphological and physicochemical identification, the isolate GNR-1 GNR-2 and GNR-3 were identified as strains of Bacteroides succinogenes, Butyrivibrio fibrisolvens and Clostridium cellobioparum, respectively.
