<P><B>Purpose</B></P><P>The previously reported Japanese clinical scoring study (JESREC) suggests that chronic rhinosinusitis (CRS) can be divided into 4 subtypes according to the degree of eosinophilic CRS (ECRS) and offers the information regarding the prognosis of CRS to clinicians. However, this scoring system has not yet been validated by an immunological study and needs to provide treatment guidelines based on underlying immunologic profiles. We investigated the immunologic profile of each CRS subgroup according to the JESREC classification and suggest its clinical application.</P><P><B>Methods</B></P><P>A total of 140 CRS patients and 20 control subjects were enrolled. All patients were classified into 4 groups according to the JESREC (non-, mild, moderate and severe ECRS). Nasal tissues were analyzed for mRNA expression of major cytokines (IL-5, IL-10, IL-13, IL-17A, IL-22, IL-23p19, IFN-γ, periostin, thymic stromal lymphopoietin [TSLP] and ST2), major chemokines (CCL11, CCL24, CXCL1 and CXCL2), transcription factors (T-bet, GATA3, RORC and FOXP3) and COL1A1 for type I collagen. Protein levels of 3 major cytokines (IL-5, IL-17A and IFN-γ) were also measured by multiplex immunoassay. Principal component analysis (PCA) was conducted to investigate the overall profile of multiple mediators.</P><P><B>Results</B></P><P>The moderate/severe ECRS showed up-regulation of type 2-related mediators (IL-5, IL-13, periostin, TSLP and ST-2), whereas INF-γ (type 1 cytokine) and CXCL1 (neutrophil chemokine) expressions were increased in non-/mild ECRS compared with moderate/severe ECRS. The JESREC classification reflected an immunological endotype. In PCA data, PCA1 indicates a relative type 2 profile, whereas PCA2 represents a type 1/type 17-related profile. In this analysis, mild ECRS was indistinguishable from non-ECRS, whereas moderate to severe ECRS showed a distinct distribution compared with non-ECRS. The JESREC classification could be divided into 2 categories, non-/mild vs. moderate/severe ECRS based on underlying immunological analyses.</P><P><B>Conclusions</B></P><P>The CRS clinical scoring system from the JESREC study reflects an inflammatory endotype. However, the immunologic profile of mild ECRS was similar to that of non-ECRS. Therefore, we propose type 2-targeted medical treatment for moderate to severe ECRS and type 1/type 17-targeted for non-ECRS and mild ECRS as the first treatment option.</P>

Yoon Tae Gyoung,Byun Boo Hyeong,Kwon Teag Kyu,Suh Seong Il,Byun Sung Hui,Kwon Young Kyu,Kim Sang Chan The Physiological Society of Korean Medicine and T 2004 동의생리병리학회지 Vol.18 No.3

Farfrae Flos has been clinically used for the treatment of asthma in traditional oriental medicine. There is lack of studies regarding the effects of Farfrae Flos on the immunological activities. The present study was conducted to evaluate the effect of Farfrae Flos on the regulatory mechanism of cytokines and nitric oxide (NO) for the immunological activities in Raw 264.7 cells. In Raw 264.7 cells stimulated with lipopolysaccharide (LPS) to mimic inflammation, Farfrae Flos water extract inhibited nitric oxide production in a dose-dependent manner and abrogated inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2). Farfrae Flos water extract did not affect on cell viability. To investigate the mechanism by which Farfrae Flos water extract inhibits iNOS and COX-2 gene expression, we examined the on the phospholylation of inhibitor κBα and production of TNF-α, IL-1β and IL-6. Results provided evidence that Farfrae Flos inhibited the production of interleukin-1β (IL-1β) and the activation of phospholylation of inhibitor κBα in Raw 264.7 cells activated with LPS. These findings suggest that Farfrae Flos can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections.

레이저 회절발법에 의한 네마틱상 MBBA의 비선형 광학성 동력학

윤보형,이일근,김성규 성균관대학교 기초과학연구소 1997 論文集 Vol.48 No.-

170㎛ 두께의 네마틱 MBBA film에 레이저 여기빔을 교차시켜 회절발을 형성시켰을 때 회절 신호를 시간적으로 추적하여 비선형 광학 동력학적 정보를 얻었다. 여기빔의 파장이 355nm이고 펄스의 세기가 10mJ/㎠일 때 회절신호의 시간적인 모양은 sub-ms, ms이 시간대에서 구분할 수 있는 4개 성분으로 구성되어 있다. 회절발의 간격이 8㎛일 때 가장 빠른 성분은 실험기기의 한계시간(~20ns)내에서 발생하고 약 10㎲시간으로 사라지는데 이는 계면의 열확산에 기인한다. 이 성분은 탐사빔의 편광에 크게 의존해서 나타난다. 네마틱상-등방상 상전이 지점에 접근하는 온도가 되면 이 편광의존성은 감소한다. 가장 약하고 느린 성분은 100ms의 시간대에서 관찰되어지는데 cis-MBBA의 질량확산이라 볼 수 있다. sub-ms 와 ms 시간대에서 회절신호의 지배적인 중간의 두 성분은 각각 지수함수적으로 증가하고 지수함수적으로 감소함을 보여준다. 두 성분의 원인은 각각 레이저 조사에 의한 온도변화로 인해 질서도의 파괴 및 회복, 레이저에 의해 형성된 광변형 상태에 의한 질서도의 파괴 및 회복에 기인한 것으로 판단된다. 온도가 상전이 점에 가까워지면 물질의 광학 비선형도는 다차회절이 눈으로도 관측될 정도로 증가한다. 다차회절신호를 휴리에 변환하여 회절발의 모양을 합성함으로써 주로 광변형상태의 존재가 다차회절의 원인, 즉 비이상적으로 높은 비선형 광학성의 중요한 원인으로 생각할 수 있다.

평야지재배 적응 조생종 벼 품종의 선발 및 품종 육성의 기초 자료로 활용코자 극조생종(1품종)과 조생종(10품종) 및 준조생(3품종)등 총 14품종을 산간지(운봉)와 평야지(익산)에 지역별 표준재배법으로 공시한 결과, 1. 극조생종 및 조생종들은 감온성이 커 산간지에서 출수가 빠르나, 준조생종에 속하는 상미벼, 영덕34호, 히또메보레 등은 감광성이 감온성보다 커, 평야지재배에서 4일정도 빨리 출수하였다. 2. 수량성은 대부분의 품종들이 산간지재배에 비해 평야지 재배에서 높았고 대체로 출수가 빠른 품종일수록 지역간의 수량차가 크게 나타났으며, 출수가 다소 늦은 준조생종들은 산간지와 평야지의 재배에서 수량차가 크지 않아 산간지 뿐만 아니라 평야지에서도 적응성이 높았다. 3. 단백질함량은 숙기가 다소 늦은 품종일수록 낮은 경향을 보였고 산간지보다는 평야지에서 낮았으며, 품종간에는 오대벼, 운봉30호, 영덕34호, 신석조생, 상미벼 등이 함유량이 낮았다. 4. 식미치는 산간지재배가 평야지에 비해 보다 높게 나타났고, 출수가 늦을수록 높았으며, 지역간 차가 크게 나타난 품종은 극조생종인 키라라397이었고, 출수가 늦은 상미벼와 히또메보레는 차가 적었다. 5. 산온도와 수량과의 상관은 산간지에서만 영향이 있을 뿐 평야에서는 영향이 적고 일사량과 일조시수가 수량에 보다 상관성이 높았으며, 식미치는 적산온도와는 부의상관, 생육 일수와는 정상관을 보였다. This experiment was carried out to clarify the difference of rice yield and the quality of rice in southern plan area and in alpine area. Yield and quality of fourteen early varieties were investigated under the different transplanting dates and planting densities in southern plan area(Iksan) and in alpine area(Unbong). In the alpine area, extremely early variety and early varieties headed early compared to the plain area, but medium early varieties headed about 4 days late unlike the alpine area. The yield difference of most early varieties including Kilara 397 of extremely early flowering variety were greater in plain area than in alpine. The different of yield between plain and alpine area was less in varieties with Sinseogjosaeng, Odaebyeo, Akidagomachi, and Yeungdeuk34. The rate of protein was lower in plain area than alpine and more lately flowering than early, but palatability of milled rice was higher at the alpine area and more lately flowering varieties. Correlation coefficients between yield and meterological data during maturity, yield shower the significant correlation with integrated solar radiation and sunshine hours at cultured in southern plan area, but it showed only cumulative temperature in alpine area. Palatability of miller rice was positive correlation at growth duration but negative correlation at cumulative temperature.

김일규,남은혜,윤영아 대한치과교정학회 발행 2005 대한치과교정학회지 Vol.35 No.6

본 연구의 목적은 브라켓 접착 시 산부식과 전처리 과정을 결합하여 잡착 단계를 단순화시킨 self-etching primer (SEP)를 사용하는 경우 접착제 종류와 타액의 존재 유무에 따른 전단결합강도의 차이에 관하여 비교 연구 하는 것이다. 소의 하악 영구 전치를 포매하여 만든 시편을 접착제의 종류에 따라 레진 접착제와 레진 강화형 글래스 아이오노머 접착제를 이용한 군으로 나누었고, 각각 37% 인산으로 산부식 후 기존의 본딩용 프라이머를 사용하여 접착한 군과, SEP를 사용하여 접착한 군으로 분류하고, 타액 오염 유무에 따라 다시 각 군을 분류하여 전단결합강도를 측정하였다. 그 결과 레진 접착제로 브라켓을 부착한 경우 SEP를 사용하여 접착한 군의 전단결합강도는 인산 처리군에 비해 낮은데 비해, 레진 강화형 글래스 아이오노머를 사용한 경우, 전처리법에 따른 전단결합강도는 통계적으로 유의한 차가 없었으며, 접착제의 종류에 관계없이 타액 오염이 존재 시에는 SEP를 사용한 군이 인산 처리군에 비해 높은 전단결합강도를 보였다. 이상의 결과에서 SEP를 사용 시 레진 접착제와 레진 강화형 글래스 아이오노머 접착제 모두 임상적으로 사용 가능한 전단결합강도를 보였으며, 특히 타액에 오염된 치면에서도 SEP를 사용하여 브라켓을 접착하는 것은 적절한 결합강도를 얻을 수 있으므로 임상적으로 유용할 것으로 생각된다. The purpose of this study was to evaluate and compare the shear bond strength of orthodontic brachets depending on the variety of adhesives and whether saliva exists. by using self-etching primer (SEP). Groups were divided according to the type of adhesive into resin adhesive (Transbond XT) and resin-medified glass ionomer cement (Fuji Ortho LC). One group of resin adhesive used XT primer after etching with 37% phosphoric acid, and the other group used self-etching primer. One group of resin-modified glass ionomer cement only used etching for bonding, and the other group used SEP. Each of the group were also classified by whether saliva was contaminated or not. and then the shear bond strength was measured. The results showed that when using resing adhesive. the shear bond strength of SEP was lower than the XT primer. In the resin-medified glass ionomer cement groups, the shear bond strength which depends on the priming method, did not have a meaningful difference statistically. When saliva was contaminated. the group which used SEP, regardless of the adhesive variety, had a greater shear bond strength than the normal priming group. From these results, SEP showed a shear bond strength that is possible to be used clinically, regardless of the adhesive variety. It can especially be clinically useful to use SEP to bond brackets even on tooth surfaces contaminated with saliva, because it offers the appropriate bonding strength as well as shorter treatment time and easy application.

Field observations for research of oceanographic characteristics in waters adjacent to fish farm on land and water quality at area where water is supplied to fish farm and area where water is discharged from fish farm are carried out in coastal waters of Pyoson located in the southeastern region of Jeju Island in March, May, August and November of 2000. Semidiurnal tides to the northeast and southwest dominate. The mean velocities of current around neap tides and spring tides are 8.52㎝·s^-1, 28.36㎝·s^-1, respectively. The difference of temperature between area where water is supplied to fish farm and area where water is discharged from fish farm is about 0.6℃. Seasonal variation range for temperature and salinity is 13.5℃ and 3.5psu, individually. Concentrations of nitrate(NO_3), phosphate(PO_4^3-), silicate(SiO_2) and COD(chemical oxygen demand) are high in autumn. Particularly, concentrations of nitrate and COD in winter and spring at station where water is supplied to fish farm are higher than these at station where water is dischared from fish farm. However, concentration of phosphate and silicate at station where is supplied to fish farm in spring, summer and autumn is higher than that at station where water is dischared from fish farm. Water quality in the study area is grade 1 and this level is kept up in the whole year.

만성 C형 간염 환자에서 페그인터페론 알파2a와 리바비린 병합 치료중 발생한 벨마비 1예

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

상용 워드프로세서 제품의 사용성 평가에 관한 연구

이규범,윤성일 공주영상정보대학 1999 논문집 Vol.6 No.-

본 연구에서는 상용 소프트웨어 제품의 사용성 평가에 관한 연구이다. 상용 워드 프로세서로 일상생활에서 많이 사용되고 있는 한글 97과 MS-Word 97의 사용성 평가에 대하여 텍스트 모드, 수식 모드, 표 모드, 단편집과 OLE기능 모드, 차트 모드 등을 다음과 같이 비교·분석하였다. 텍스트 모드에서 한글 97은 완성형과 조합형을 지원하는 반면 MS-Word 97에서는 완성형만을 지원함을 알 수 있다. 수식 Mode에서는 한글 97은 수식 입력도구를 사용하므로 작성하기에 편리한 반면 MS-Word 97은 개체 삽입으로 인한 수식모드의 작성이 편리하지 않음을 알 수 있으며, 편집 시간 면에서 한글 97보다 MS-Word 97이 약 2배정도 많이 소요됨을 알 수 있고, 또한 파일 크기도 약 6배정도로 MS-Word 97이 더 많이 필요함을 알 수 있다. Table Mode에서 한글 97은 도표 캡션을 지정할 수 있는 반면 MS-Word 97에서는 도표 캡션을 직접 작성해야 하는 불편함을 알 수 있다. OLE기능 모드에서 MS-Word 97은 Drag & Drop 기능이 있는 반면, 한글 97에서는 직접적인 Drag & Drop 대신에 복사 기능과 붙여 넣기로 같은 결과를 얻어낼 수 있음을 확인하였다. Chart Mode에서 한글 97은 자체적으로 필요한 차트기능이 지원되는 반면 MS-Word 97은 엑셀 등의 차트기능이 있는 소프트웨어를 불러와서 사용해야함을 알 수 있다.
