  • Objective The purpose of this study was to confirm the effects of Galgeunhwanggeumhwangryeon-tang in reducing inflammation through the endocannabinoid system (ECS) control in atopic dermatitis. Methods 8-week-old Balb/C mice were divided into 4 groups: contorl group (Ctrl), lipid barrier elimination group (ADE), palmitoylethanolamide treated group after lipid barrier elimination (PEA), and Galgeunhwanggeumhwangryeon-tang applied group after lipid barrier elimination (GGRT). After inducing atopic dermatitis, cannabinoid receptor (CB) 1, CB2, CD68, phosphorylated inhibitor kappa B (p-IκB), inducible nitric oxide synthase (iNOS), substance P and serotonin were observed to confirm the regulation of the ECS, macrophage activity and mast cell activity. Results CB1 and CB2 showed higher positive reactions in the GGRT than in the LBE and PEA. CD68, p-IκB and iNOS showed higher positive reaction in the LBE, PEA and GGRT than in the Ctrl, but the increase in the positive reaction was lower in the GGRT compared to the LBE and PEA. Substance P and serotonin showed higher positive reaction in the LBE, PEA and GGRT than in the Ctrl, but the increase in the positive reaction was lower in the GGRT compared to the LBE and PEA. Conclusions The effects of Galgeunhwanggeumhwangryeon-tang were confirmed though the regulation of the ECS, macrophage activity and mast cell activity.

  • Ankyrins are a ubiquitously expressed family of intracellular adaptor proteins involved in targeting diverse proteins to specialized membrane domains in both the plasma membrane and the endoplasmic reticulum. Recently, the studies with C-terminus of ankyrins have identified that ankyrin-B is capable of interacting with Hsp40 and sAnkl is capable of interacting with obscurin and titin, but the function of C-terminal domain of ankyrin-G remains unknown. To identify proteins interacting C-terminus of ankyrin-G, we used the C-terminus of ankyrin-G as a bait for a yeast two-hybrid screen of brain cDNA library. Approximately 1.33$\times$l0$^6$ transformants were screened, of which 13 positive clones were obtained as determined by activation of HIS3, ADE2 and MELl reporter genes. Sequence analyses of these 13 plasmids revealed that cDNA inserts of 13 colonies showed highly homologous to 11 genes, including 5 known (i.e., Na$^+$/K$^+$ ATPase $\beta$1, SERBPl, UTF2, cytochrome C oxidase and collagen IV $\alpha$2) and 6 unknown genes. The evaluation of the proteins that emerge from these experiments provides a rational approach to investigate the those proteins significant in interaction with ankyrin-G.

  • 오염된 연약지반에 편재하중이 작용하는 경우에 있어서 지반의 소성화에 따른 측방유동에 대한 거동을 규명하기 위하여 기존의 이론적인 배경을 고찰하고, 모형실험을 통하여 실측한 결과를 상호 비교.분석하였다. 모형실험은 모형재하장치인 토조와 재하틀 및 재하판을 제작하여 토조 안에 함수비를 일정하게 유지한 상태에서 자연지반의 시료와 오염물질을 점진적으로 증가시킨 지반시료에 대하여 일정한 시간 간격으로 편재하중을 증가시키면서 침하량과 측방변위량 및 융기량 등을 관측하였다. 그 결과 한계하중은 실험값이 Tschebotarioff(q$_{cr}$=3.0$_{cu}$)의 제안값과 Meyerhof(q$_{cr}$=(B/2H+$\pi$/2)$_{cu}$)의 제안값에 근접하여 q$_{cr}$=2.78$_{cu}$값을 나타냈고, 극한하중은 Prandtl의 제안값에 근접하여 q$_{ult}$=4.84$_{cu}$값을 나타냈다. 측방유동압은 Matsui.Hong의 이론식에 의해서 산정함이 비교적 적절하며, 측방유동압의 최대값은 토층두께(H)의 0.3H 부근에서 발생하였으며, 복합형과 Poulos의 분포형태 및 오염되지 않는 연약점토(CL, CH)지반 보다 지표면측으로 상승하여 발생하였다. 안정관리방법은 지반의 측방유동에 의한 소성변위량을 많이 이용하고 있는 부영.교본, 자전.관구, 송미.천촌 등의 안정관리도에 적용한 결과 송미.천촌의{S$_{v}$-(Y$_{m}$/S$_{v}$)}관리도와 자전.관구의 {(q/Y$_{m}$)-q}관리도에서 얻어진 극한하중은 하중-침하량곡선 (q-S$_{v}$)에서 얻어진 극한하중 보다 적은 경향을 나타냈다.

  • A study was conducted to determine the influence of feed form and microbial enzyme supplementation on energy utilization, bone quality, and amino acid and mineral digestibility of broiler chickens. Four hundred and eighty Ross 308, day-old broiler chickens were randomly assigned to eight diets formulated from commonly used ingredients in Tanzania. A 2 (pellet or mash) ${\times}$ 4 (control, Axtra XB, Quantum Blue (QB) and Axtra XB + QB enzyme) factorial array in a completely randomized design having six replicates per treatment (10 birds per replicate) was used. Birds were raised in climate-controlled rooms in a 3-phase; starter (0-10 days), grower (11-24 days) and finisher (25-35 days). Apparent metabolizable energy (AME), metabolizable energy intake, net energy of production, energy retained as protein (REp), and efficiency of metabolizable energy use for energy and protein retention were higher (p < 0.05) in birds fed pelleted diets. The AME and REp was higher (p < 0.05) with enzyme supplementation. Ash content, weight, length, width and breaking strength of tibia bones were highest (p < 0.05) in birds on pelleted diets. Tibia bone traits were improved (p < 0.05) when enzymes were included, particularly in a combination of QB and Axtra XB. However, potassium, magnesium, and zinc contents were highest (p < 0.05) when QB was supplemented. Digestibility of all amino acids was higher (p < 0.05) in birds supplied with pellets and with enzyme supplementation for most amino acids, except for serine. There was a positive interaction (p < 0.05) between feed form and enzymes on lysine and phenylalanine digestibility. Digestibility of Ca, P, K, S, Zn, and Fe was higher (p < 0.05) in birds fed pelleted diets, while those on mashed diets had higher (p < 0.05) digestibility of Cu and B. The digestibility of P, K, and Zn was highest (p < 0.001) when QB was added, while Ca, P, S, and B digestibility was highest when a combination of Axtra XB + QB was applied. Pelleted diets with or without enzymes improved energy utilization, digestibility of amino acids, and minerals, and increased bone strength in broiler chickens.

  • POLARBEAR is a ground-based experiment located in the Atacama desert of northern Chile. The experiment is designed to measure the Cosmic Microwave Background B-mode polarization at several arcminute resolution. The CMB B-mode polarization on degree angular scales is a unique signature of primordial gravitational waves from cosmic inflation and B-mode signal on sub-degree scales is induced by the gravitational lensing from large-scale structure. Science observations began in early 2012 with an array of 1.274 polarization sensitive antenna-couple Transition Edge Sensor (TES) bolometers at 150 GHz. We published the first CMB-only measurement of the B-mode polarization on sub-degree scales induced by gravitational lensing in December 2013 followed by the first measurement of the B-mode power spectrum on those scales in March 2014. In this proceedings, we review the physics of CMB B-modes and then describe the Polarbear experiment, observations, and recent results.

  • 목초하고 피해를 최소화할 수 있는 방목개시시 초장(주구 3처리 ; 15, 30, 45cm)과 여름철 혼파된 화본 과목초에 경합력이 낮은 화이트클로바 품종(세구 4처리; Regal, Tahora, Brown, STVR)을 선발하기 위해 제주농업시험장의 사료작물시험포장에서 1994년 9월부터 1996년 10월까지 2년간 시험이 수행되었다. 혼파목초의 건물수량은 전체적으로 평균 예취시 초장 30cm 이상에서 유의적 증수를 보였으나(P<0.05) 2년차에는 유의적 차이가 없었다. 2년째 수확시에만 목초의 건물수량이 Brown 품종구에서 타 품종 보다 통계적으로 고도의 유의적 증가를 보였다.(P<0.01). 2년차에 예취시 초장에 따른 식생구성율에 분명한 차이를 발견치 못하였다. 다만 white clover 품종 처리별로 비교할 때 white clover의 비율은 Regal와 Tahora구에서 보다 Brown과 SRVR 처리구에서 낮아지는 경향이었다. 2년차 마지막 예취시에 잡초비율도 주구나 세구간 효과를 발견치 못하였다. 목초의 ADF와 NDF 함량은 예취 초장 15cm에서 가장 낮았고 인 함량은 15cm에서 가장 높았으며 모두 통계적으로 유의차가 인정되었다(P<0.05). 혼파목초의 K 함량은 30cm 초장에서 가장 낮았으며 (P<0.05) 질소 함량은 예취시 초장과 품종간에 상호작용이 있었으며 통계적으로 고도의 유의차가 있었다(P<0.01). White clover의 품종이 목초의 일반성분 함량에 영향을 주지 못하였다. 결론적으로 방목형일 때 15cm 초장에서 화이트 클로바 SRVR을 이용하는 것이 사료가치도 유지하며 두과와 화본과목초 균형을 유지하는 데 적합하다고 사료된다.
