본 시험은 국내에 도입된 자동착유시스템 설치농가에서 사육하고 있는 젖소들의 검정성적을 이용하여 자동착유시스템 설치 전과 후의 산유량과 유성분 및 체세포 수 변화를 알아보기 위하여 실시하였다. 분석에 이용된 자료는 자동착유시스템이 설치된 4개의 농가에서 자동착유시스템 설치 1년 전과 1년 후의 검정기록이 있는 147두를 대상으로 하였다. 산유량을 비교한 결과, 자동착유시스템 설치 1년 전의 기존착유시스템에서 산유량이 30.37 kg인 것에 비하여 자동착유시스템 설치 1년 후의 산유량은 34.27 kg으로 유의성 있게 높아진 것을 확인할 수 있었다. 이는 착유회수가 AMS 설치 1년 전의 기존착유 2.0회에 비하여 자동착유시스템에서 2.62회로 증가한 것에 기인한 것으로 생각된다. 유지율 (%)은 자동착유시스템 설치 전 $3.7{\pm}0.5%$에 비하여 설치 후 $3.8{\pm}0.5%$으로 약간 높은 경향을 나타내었으나 유의적인 차이는 나타나지 않았다. 그러나 유지방량 (kg)은 기존 착유시스템에서 보다 자동착유시스템으로 전환 후 유의적으로 높게 나타났는데, 이는 산유량 증가에 기인된 것이다. 유단백율 역시 자동착유시스템 설치 전 $3.2{\pm}0.2%$와 설치 후 $3.2{\pm}0.2%$로 차이가 없었다. 그러나 유단백량에 있어서는 유지방과 같이 산유량 증가로 인하여 기존 착유시스템에 비하여 자동착유시스템에서 유의적으로 높았다. 체세포 수는 자동착유시스템 설치 전 $169.4{\pm}188.5$천개/ml로 1등급 수준이었던 것에 비하여 설치 후 $314.4{\pm}279.9$천개/ml로 2등급 수준으로 유의성 있게 증가하였음을 알 수 있다. 이상의 결과를 종합하여 보면, 자동착유시스템 설치에 따라 산유량은 증가하나 유질등급에 영향을 주는 체세포 수가 증가하는 것으로 나타나 자동착유시스템을 설치하려는 농가에서는 이에 대한 고려가 있어야 할 것으로 사료된다. 그러나 체세포 수가 증가한 것이 자동착유시스템 자체의 문제인지 아니면 자동착유시스템을 운영하는 관리자의 관리미숙으로 인한 것인지는 명확하지 않아 더 많은 연구가 필요하다고 하겠다.

목 적 : 대혈관 합병증은 1형 당뇨병에서 주된 사망 원인으로 합병증을 예방하고 조기에 발견하는 것은 중요하므로, 저자들은 소아-청소년기에 1형 당뇨병으로 진단된 젊은 성인에서 대혈관 합병증의 발생 여부를 알아보고자 혈관초음파 검사를 통해 동맥경화의 초기 변화를 측정하였고, 이 변화와 관련된 위험인자를 분석하기 위해 본 연구를 시행하였다. 방 법 : 서울대학교병원에서 18세 이전에 1형 당뇨병으로 진단받고 추적 관찰 중인 20대의 72명의 환자들과 건강한 20명의 대조군을 대상으로 하였다. 환자들에서 고혈압과 고지혈증의 빈도 및 관련 인자를 알아보았으며, 환자군과 대조군 간에 혈관 초음파 검사를 통해 측정한 FMD, mean IMT를 비교하였고, 위험인자와의 상관성을 분석하였다. 결 과 : 72명의 대상 환자 중 32명(44.4%)에서 고혈압이 있었고, 고혈압군은 정상 혈압군 보다 남자의 빈도(P=0.03)와 평균 체질량지수(P=0.04)가 더 높았다. LDLc이 100 mg/dL 이상으로 측정된 환자는 31명(N=69, 44.9%)이었고, 전체 환자군의 LDLc은 평균 당화혈색소(r=0.32, P=0.008), 하루 총 인슐린 사용량(r=0.27, P=0.02)과 양의 상관관계를 보였다. Mean IMT는 환자군이 대조군 보다 유의하게 더 두꺼웠고($0.43{\pm}0.06$ mm vs $0.39{\pm}0.06$ mm, P=0.03), FMD는 두 군 사이의 통계적 유의성은 없었으나, 환자군 내에서 사춘기발현 이후의 유병기간이 길수록 FMD는 감소하는 경향을 보였다(r=-0.34, P=0.01). 결 론 : 20대의 1형 당뇨병 환자에서도 동맥경화가 진행되고 있으므로 대혈관 합병증의 위험인자에 대한 선별검사 및 이의 조절이 필요하며, 1형 당뇨병이 있는 젊은 성인뿐만 아니라 청소년기의 환자에서도 대혈관 합병증의 위험인자에 대한 주기적인 평가가 필요할 것으로 생각된다.

본 연구는 치근관 감염병소에서 세균을 분리 및 동정하고, 8종의 항생제들에 대한 분리균주들의 감수성을 조사하기 위하여 실시하였다. 세균에 감염된 27개 치아의 괴사된 치근부 치부소직을 바비드 브로치나 페이퍼 포인트로 무균적으로 채취하였다. 치수가 채취된 부위의 바비드 브로치와 페이퍼 포인트를 500 ul의 $1{\times}PBS$ 용액에 담아 잘 혼합하고, 이를 5% 양혈이 포함된 BHI 한천배지(혈액한천배지)에 도말하여 $37^{\circ}C$ 혐기성 배양기에서 2-5일 동안 배양하였다. 혈액한천배지에서 자라난 세균은 16S rRNA 유전자(rDNA) 염기서열결정법을 이용하여 종수준으로 동정하였다. 이들 균주들의 8종 항상제에 대한 감수성은 최소성장억제농도 측정법으로 조사하였다. 본 연구결과, 101개의 세균 집락이 생겼고, Streptococcus spp. (29.7%)와 Actinomyces spp. (21.8%)가 가장 많이 검출되었다. 이들 균주들 중 9균주는 실험 도중 소실되거나 액체배지에 자라지 않아서 항생제 감수성 심험에서는 제외되었다. 각 항생제들에 대한 감수성을 조사한 결과, 분리된 균주들 중 80(87.0%) 균주가 클린다마이신에 감수성을 보였으며, 세프록심 아세틸과 테트라사이클린에 69(75.0%)가, 오그멘틴에 66(71.7%) 균주가, 페니실린 G에 63(68.5%) 균주가, 에리트로마이신에 61(66.3%) 균주가, 아목시실린에 41(44.6%) 균주가 감수성을 보였다. 그러나 시플록사신에는 29(31.5%) 균주만이 감수성을 보였다. 이러한 8종 항생제에 대한 균주들의 감수성 양상은 세균 종의 종류보다는 분리된 숙주에 따라 차이가 있었다. 이러한 결과는 치근관 감염질환의 치료에 항생제가 필요할 경우 항생제 감수성검사를 병행하는 것이 효과적임을 시사한다.

Objective : Lumbar disc herniation can induce sciatica by mechanical compression and/or chemical irritation. The aim of this study was to compare the effects of GCSB-5 (Shinbaro$^{(R)}$) and NSAIDs on pain-related behavior and on the expressions of microglia, astrocytes, CGRP, TRPV1, IL-6, and CX3CL1 in a rat model of lumbar disc herniation. Methods : 112 male Sprague-Dawley rats underwent implantation of nucleus pulposus to a dorsal root ganglion (DRG). Rats were divided into five groups as follows; a saline group (the vehicle control group) (n=27), a 10 mg/kg aceclofenac group (the aceclofenac group) (n=22), and 100, 300 or 600 mg/kg GCSB-5 groups (the GCSB-5 100, 300, or 600 groups) (n=21 for each group). Rats were tested for mechanical allodynia at 3 days after surgery and at 1 day, 3 days, 7 days, 14 days, 21 days, 28 days, 35 days, 42 days, 49 days, and 56 days after treatment commencement. Immunohistochemical staining of microglia (Iba1), astrocytes (GFAP), CGRP, and TRPV1, and PCR for IL-6 and CX3CL1 were performed on spinal dorsal horns and DRGs at 56 days after medication commencement. Results : After 56 days of GCSB-5 300 administration, mechanical withdrawal thresholds were significantly increased (p<0.05), and immunohistochemical expressions of Iba1, GFAP, CGRP, and TRPV1 were reduced than other groups, but this difference was not statistically significant. Conclusion : These results indicate GCSB-5 reduces mechanical allodynia and downregulates neuroglial activity and the expressions of CGRP and TRPV1 in the spinal segments of a rat model of lumbar disc herniation.

An ethanol-producing yeast strain, CHFY0201, was isolated from soil in South Korea using an enrichment technique in a yeast peptone dextrose medium supplemented with 5% (w/v) ethanol at $30^{\circ}C$. The phenotypic and physiological characteristics, as well as molecular phylogenetic analysis based on the D1/D2 domains of the large subunit (26S) rDNA gene and the internally transcribed spacer (ITS) 1+2 regions, suggested that the CHFY0201 was a novel strain of Schizosaccharomyces pombe. During shaking flask cultivation, the highest ethanol productivity and theoretical yield of S. pombe CHFY0201 in YPD media containing 9.5% total sugars were $0.59{\pm}0.01$ g/l/h and $88.4{\pm}0.91%$, respectively. Simultaneous saccharification and fermentation for ethanol production was carried out using liquefied cassava (Manihot esculenta) powder in a 5-l lab-scale jar fermenter at $32^{\circ}C$ for 66 h with an agitation speed of 120 rpm. Under these conditions, S. pombe CHFY0201 yielded a final ethanol concentration of $72.1{\pm}0.27$ g/l and a theoretical yield of $82.7{\pm}1.52%$ at a maximum ethanol productivity of $1.16{\pm}0.07$ g/l/h. These results suggest that S. pombe CHFY0201 is a potential producer for industrial bioethanol production.

The aim of this study is to compare the sensitivity of both two NCI-H292 and A549 cell types to acute inflammatory responses induced by cigarette smoke. For this, we treated two kinds of smoke fractions derived from 2R4F reference cigarettes: total particulate matter(TPM) collected onto a Cambridge filter pad and gas/vapor phase(GVP) prepared by bubbling through in buffer solution. When we measured cellular cytotoxicity by neutral red uptake assay after treatment for 24 hours, TPM and GVP induced cytotoxic effect in a dose-dependent manner in the range of 10-$100{\mu}g$/mL and 60-$300 {\mu}g$/mL., respectively, in both cell types without any cellular difference. Additionally, when we examined acute inflammatory responses by analyzing cytokines secreted into culture media including tumor necrosis factor-$\alpha$ (TNF-$\alpha$), interleukin-8(IL-8), and transforming growth factor-$\alpha$(TGF-$\alpha$) as well as matrix metalloproteinase-1(MMP-1), the treatment with smoke fractions increased those marker proteins in a dose-dependent manner in NCI-H292. Meanwhile, in A549 cells only MMP-1 was observed to be increased in a dose-dependent fashion. Collectively, our data indicate that NCI-H292 cell type is more sensitive to cigarette smoke-induced inflammatory response than A549 cells. This suggests that NCI-H292 could be useful as an in vitro evaluation tool to assess harmful effects of cigarette smoke.

Background: In order to evaluate the effect of pH, known as a critical factor for shaping the biogeographical microbial patterns in the studies by others, on the bacterial diversity, we selected two sites in a similar geographical location (site 1; north latitude 35.3, longitude 127.8, site 2; north latitude 35.2, longitude 129.2) and compared their soil bacterial diversity between them. The mountain soil at site 1 (Jiri National Park) represented naturally acidic but almost pollution free (pH 5.2) and that at site 2 was neutral but exposed to the pollutants due to the suburban location of a big city (pH 7.7). Methods: Metagenomic DNAs from soil bacteria were extracted and amplified by PCR with 27F/518R primers and pyrosequenced using Roche 454 GS FLX Titanium. Results: Bacterial phyla retrieved from the soil at site 1 were more diverse than those at site 2, and their bacterial compositions were quite different: Almost half of the phyla at site 1 were Proteobacteria (49 %), and the remaining phyla were attributed to 10 other phyla. By contrast, in the soil at site 2, four main phyla (Actinobacteria, Bacteroidetes, Proteobacteria, and Cyanobacteria) composed 94 %; the remainder was attributed to two other phyla. Furthermore, when bacterial composition was examined on the order level, only two Burkholderiales and Rhizobiales were found at both sites. So depending on pH, the bacterial community in soil at site 1 differed from that at site 2, and although the acidic soil of site 1 represented a non-optimal pH for bacterial growth, the bacterial diversity, evenness, and richness at this site were higher than those found in the neutral pH soil at site 2. Conclusions: These results and the indices regarding diversity, richness, and evenness examined in this study indicate that pH alone might not play a main role for bacterial diversity in soil.

Polylactic acid (PLA) has been highlighted as an alternative renewable polymer for the replacement of petroleum-based plastic materials, and is considered to be biodegradable. On the other hand, the biodegradation of PLA by terminal degraders, such as microorganisms, requires a lengthy period in the natural environment, and its mechanism is not completely understood. PLA biodegradation studies have been conducted using mainly undefined mixed cultures, but only a few bacterial strains have been isolated and examined. For further characterization of PLA biodegradation, in this study, the PLA-degrading bacteria from digester sludge were isolated and identified using a polymer film-based screening method. The enrichment of sludge on PLA granules was conducted with the serial transference of a subculture into fresh media for 40 days, and the attached biofilm was inoculated on a PLA film on an agar plate. 3D optical microscopy showed that the isolates physically degraded the PLA film due to bacterial degradation. 16S rRNA gene sequencing identified the microbial colonies to be Pseudomonas sp. MYK1 and Bacillus sp. MYK2. The two isolates exhibited significantly higher specific gas production rates from PLA biodegradation compared with that of the initial sludge inoculum.
