Cytokines are known to function as regulatory molecules that can be produced by virtually every nucleated cell type in the body, including lymphocytes, monocytes/macrophages, epithelial cells, fibroblasts, and many others. Cytokines include lymphocyte-derived factors (lymphokines), monocyte-derived factors (monokines), hematopoietic factors (colony-stimulating factors), connective tissue/growth factors, and chemotactic chemokines. Cytokines released in response to infection can affect tumor development in different ways. When exposed to infectious agents, cytokines are secreted by sentinel cells, such as macrophages and dendritic cells. These cytokines include interleukin 1 (IL-1) and tumor necrosis factor-α, as well as others, such as IL-6, IL-12, and IL-18. When released in sufficient quantities, these molecules can cause inflammation. Chronic inflammation is highly associated with tumor initiation, promotion, and progression. In this article, we review the roles and mechanisms of cytokines in tumor development.

Association of 20 potential ATP2B1‐interacting genes with blood pressure in Koreans

Kyung‐Won Hong,Hyun‐Seok Jin,Ji‐Eun Lim,Bermseok Oh 한국유전학회 2011 Genes & Genomics Vol.33 No.3

Plasma membrane calcium‐transporting ATPase 1 (ATP2B1)is associated significantly with blood pressure in Caucasians and Asians. ATP2B1 regulates calcium homeostasis and belongs to the P‐type calcium pump family; several studies have identified diverse proteins that bind to ATP2B1. We hypothesized that ATP2B1 regulates blood pressure through ATP2B1‐interacting genes. To this end, 20 potential ATP2B1‐interacting genes were selected, 197 SNPs of which were analyzed for their association of systolic and diastolic blood pressure. These 20 genes were categorized into 2 groups: ATP2B1‐binding genes and ATP2B1‐cleaving calpain family members. Three ATP2B1‐binding genes (CALM1, NOS1, and PDLIM1)were associated with blood pressure, and a SNP in CALM1(rs2401887) generated the strongest association signal (beta=‐3.60±0.92, p=8.9×10^(‐5) for systolic blood pressure and beta=‐1.40±0.62, p=0.02 for diastolic blood pressure). Of the calpain family members, 3 genes (CAPN6, CAPN9, and CAPN10)were associated with blood pressure, and the CAPN10 SNP rs4676348 yielded the strongest association signal (beta=‐0.88±0.27, p=0.001 for systolic blood pressure and beta=‐0.58±0.18, p=0.015 for diastolic blood pressure). Further, the interaction of CALM1 to ATP2B1 was examined using the blood pressure of individuals who carried both variants of CALM1and ATP2B1 genes. Similarly the interaction of CAPN10 to ATP2B1 was also examined. The CALM1 variant (rs2401887)and CAPN10 variants (rs4676348) appear to decrease blood pressure further in addition to the decrease by the variant (rs17249754) of ATP2B1, which suggests that ATP2B1 might regulate blood pressure through the ATP2B1‐interacting genes CALM1 and CAPN10.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

1. Objective This is a basic study about the response of herbal medicine to EAV. The purpose was to investigate how the meridian of EAV responded to herbal medicine and how EAV was applied to the diagnosis of Sasang constitution. 2. Materials & Methods The subjects of this study were patients who were being treated in the Dept. of Constitutional Medicine ot Kyung-Hee Medical Center. The study examined how herbal medicine affected the maximum value and the indicator drop and how each constitution responded differently to the constitutional herb medicine. 3. Results & Conclusions 1) When comparing the maximum value and ID of the worst BAP before and after the experiment with herbal medicine, the maximum value significantly went up and the ID significantly went down in all the herbal medicines. So we confirmed that all the herbal medicines positively affected the change of the maximum value and ID. 2) The changes in the maximum value induced by herbal medicines were significantly different according to the constitution of Dokhual Jihwang Tang, and Hyangbuja Palmul Tang. Although Dokhual Jihwang Tang was soyangin's herb medicine in Sasang constitutional medicine, it raised the value of soeumin higher than that of soyangin. Hyangbuja Palmul Tang which was soeumin's herb medicine raised the value of soeumin higher than that of the other constitution. 3) The changes of ID were not significantly different in the constitution.

ZnO 바리스터의 표면에서 전기적 특성은 프랙탈 방법으로 정량화 하였다. 전기적 특성은 주파수 변화에 대해 유전율을 측정하였다. 프랙탈 차원이 높을수록 입자는 복잡한 형성이었으며 프랙탈 차원과 전기적 특성은 입계와 기공이 차지하는 입계의 밀도 분포도와 관계가 있었다. Sb_2O_3 첨가에 의해 ZnO 입자는 스피넬 구조의 생성에 의해 성장이 억제되었으며 Sb_2O_3가 첨가되지 않는 시료 ZnO1은 입자의 크기가 제어되지 않아 내부 정전용량이 감소되어 유전율이 작았다. A new fractal method is presented to understand more clearly the effect of variations on ZnO surface on electrical characteristics. The electrical characteristics have been investigated in terms of dielectric characteristics with frequency. If Fractal dimension is high, the grain density and grain boundary is complex in the surface of ZnO varistors. The ZnO grain with addition of Sb_2O_3 was restricted by formation of spinel structure. The dielectric constant was low value decreasing with static capacitance, which has not controlled ZnO grain size.

Neomorphogenesis of cartilage using chondrocyte-polymer constructs is a potential source for development of cartilage reconstruction. Current tissue engineering techniques of neocartilage rely on in vivo implantation of polymer-chondrocyte constructs. The purpose of this study was to find a way to bioengineer cartilage in vitro by entrapping chondrocytes in a molded autologous fibrin glue. Chondrocytes isolated from the cartilage of rabbit joints were combined with fibrinogen extracted by a single cryoprecipitation of autologous plasma, and they were then polymerized with thrombin to create a fibrin glue with a final cell density of 2.5x10?? cells/ml. The collagen for a control study was used as a polymer. The polymer-chondrocyte constructs were cultured for 4 weeks and the fibrin-chondrocyte constructs molded in the shape of a human ear were cultured for 6 weeks in vitro. Morphometric, histochemical, and histomorphometric analysis including glycosaminoglycan quantitation confirmed the following results: 1) Highly-concentrated autologous fibrinogen was easily extracted by a single cryoprecipition of autologous olasma. 2) The fibrin-chondrocyte constructs demonstrated the presence of actively proliferating chondrocytes with the production of cartilaginous matrix(collagen and glycosaminoglycan) at 1 week after culture, as well as gross and histologic evidence similar to those of normal cartilage at 3∼4 weeks after culture. 3) The collagen-chondrocyte constructs demonstrated lower degrees of hardness and transparency, as well as a lower density of cells and glycosaminoglycan during the culture period. 4) Neocartilage generated from fibrin-chondrocyte constructs in the shape of a human ear nearly retained their original configuration and size without degeneration for 6 weeks of culture in vitro. This study demonstrated a novel method for bioengineering the molded cartilage in vitro using autologous fibrin glue as a matrix scaffold. The generated cartilage showed gross and histologic evidence similar to those of normal cartilage, retaining the original gross dimension. With further refinement, this may be a new application of tissue engineering for the reconstruction of cartilage.

콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.
