문기원,권순길,김혜영 충북대학교 의과대학 충북대학교 의학연구소 2003 忠北醫大學術誌 Vol.13 No.2

만성 신부전에서는 사구체 여과율이 감소함에 따라 농축능은 손상되지만 희석능은 오랜 기간 유지되기 때문에 심한 저나트륨혈증은 잘 발생하지 않는 것으로 알려져 있다. 저자들은 잘못된 민간 의료지식으로 인하여 만성 신부전 환자에서 과도한 수분섭취로 유발된 심한 저나트륨혈증을 합병증 없이 치료한 증례를 경험한 바 있어 보고하는 바이다. Hyponatremia is one of the most common electrolytes imbalances in clinical medicine. However, it may be fatal if not corrected appropriately. In pre-dialytic chronic renal failure patients, severe hyponatremia is rare, because the dilutional capacity of the nephron is well preserved despite of diminished glomerular filtration rate. We report a case of severe hyponatremia induced by excessive water intake in a 33-year-old woman with chronic renal failure, treated successfully with diuretics and 3% saline. She had drunken 2-3 liters of free water daily for 7 days, and nausea, vomiting and dyspnea were developed 2 days later. At admission, serum sodium concentration was 103 mEq/L and serum creatinine was 4.7 mg/dL. Salt and free water intake were restricted and furosemide was administered intravenously, but serum sodium concentration rose only by 2 mEq/L. Then, 3% saline was added and serum sodium concentration rose to 118 mEq/L after 48 hours. On 7th hospital days, serum sodium concentration was 132 mEq/L, the patient discharged without any complication at all.

Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 49-65, 2004. The purpose of this study is development of posture evaluation and Range of Motion(ROM) system by using digital vision analysis method. The results of this study are as follows. First, Scoliosis evaluation through this research measurement system represent 3mm error in 7 cervical point and deepest lumbar point, 0.7mm error in other point. This mean this research measurement system have a reliability for scoliosis evaluation. Second, for spine line evaluation on high fat subject, we need reconstrection spine line after mesurement for fat thickness in 7 cervical point and deepest lumbar point. Third, In pedioscope error test, it present 0.01848cm in X axis and 0.01757cm in Y axis. This results mean pedioscope have a reliability foot evaluation. Forth, Posture evaluation and Range of Motion measurement system by using digital vision analysis method can fast measure in range of motion and foot evaluation and posture. therefore we can expect this system application in young people posture clinic center and hospital and so on.

기둥유사법에 의한 비대칭 변단면 사각형골조의 해석

문연준,김순철 東新大學校 1997 論文集 Vol.9 No.-

The column analogy method is most useful in the analysis of beams, curved members like arches and rigid frame with two fixed supports. The analysis of these structures by the method of consistent deformation involves the solutions of three simultaneous equations because these structures are statically indeterminate to the third degree. In the column analogy method, however, the moment at any point in the given structure can be computed directedly and easily. In this paper, only the bending moments for the unsymmetrical nonprismatic quardrangular frames are to be formulated in general expressions and to be tabulated by the computer. To see how the tabulated data are applied, one example of bending moment calculations of unsymmetrical nonprismatic quadrangular frame will be given.

세포질의 알카리화가 Fibroblast Monolayer에 미치는 Mitogenic Effect

文順玉 水原大學校 1989 論文集 Vol.7 No.-

Stimulation of ?? exchange by growth factors has been implicated as an event required for progression of cells from quiescence to a state competent for proliferation. To test this hypothesis, confluent monolayers of mouse and human fibroblasts, were treated with the carboxylic ionophore monensin which catalyzes ?? exchange at the plasma membrane. When ?? monensin is incubated with cells DNA synthesis is stimulated. Growth factors that stimulate ?? exchange also induce expression of two cellular proto-oncogenes, c-fos and c-myc. These gene products have been implicated as regulators of proliferation of mammalian cells. Transient exposure of quiescent Balb/c-3T3 cells to monensin stimulates expression of both c-fos and c-myc proto-oncogene. These data suggest that stimulation of ?? exchange regulates the level of mRNA decoding for c-fos and c-myc and provide a key stimulus for cell proliferation.

서식문서의 구조분석 및 자동 HTML 변환

문경애,백순흠 공주영상정보대학 1999 논문집 Vol.6 No.-

본 논문에서는 내용이 채워진 임의의 서식문서의 구조분석 및 표현에 관한 방법을 설명하였다. 제안한 방법은 위상(topology)을 유지하는 범위에서는 변형이 있어도 동일한 서식으로 간주하는 논리적 형식의 구조분석 방법으로 크기와 위치의 변형에 민감하지 않으므로 최소한의 등록으로 서식의 분류가 가능하였다. 또한 기존의 방법들에서 처리가 곤란했던 서식의 선이 깨어진 경우, 점선의 서식의 경우, 항목 내에 필기한 문자와 서식의 선이 접촉된 경우, 서식이 기울어진 경우 등에서도 좋은 결과를 보여 다양한 실험 데이터에 대해 약 97% 이상의 항목 추출율을 보였다. 그러나 서식 선과 항목 내에 필기한 문자가 붙은 경우 추출된 각 항목, 즉 내용필드의 문자들이 파손되어 문자 인식율이 저하되었다. 앞으로 전체적인 F-DAS시스템의 성능 향상을 위해서는 항목내의 인쇄 및 필기 문자들의 분리 방법에 관한 연구 및 서식과 붙어서 생긴 파손된 문자의 복원에 관한 연구가 이루어져야 할 것이다.

측백나무 추출물의 Monoamine Oxidase 저해활성

이문순,오지훈,이학수 忠北大學校 農業科學硏究所 2012 農業科學硏究 Vol.28 No.2

Monoamine oxidase (MAO) exists in the outer membrane of mitochondria and contained a flavin adenine dinucleotide (FAD). MAO is classified into two forms, A-type (MAO-A) and B-type (MAO-B) on the basis of their different specifications toward substrates and inhibitors. This study was carried out to identify inhibitory components on MAO from Thuja orientalis seed extract by bioassay- guided isolation. The seeds of Thuja orientalis was extracted with 80% MeOH, and the MeOH extract was fractionated with n-hexane, chloroform, ethylacetate and n-butanol successively. The n-hexane and chloroform fraction showed relatively high inhibitory activity on MAO. Among the fractions from n-hexane layer through silicagel column chromatography, the fractions 2, 3 and 4 showed strong inhibitory activity on MAO

Colo 320 세포에서 Streptomyces sp. No.2303 배양추출액의 항암활성 작용기작의 규명

문순옥 수원대학교 자연과학연구소 1998 자연과학논문집 Vol.1 No.-

Streptomyces sp. No. 2303 was selected previously by its cytotoxic effect against human lung carcinoma A549 cells and its inhibitory activity to expression of oncogene, c-myc. In this study, the cytotoxic effect of N0.2303 on c-myc amplified human cancer cell, Colo320 DM and HSR was performed by using 3-(4,5-dimethyltiazol-2-yl)2, 5-diphenyltetrazolium bromide(MTT) assay. Culture extract of No.2303 showed cytotoxic effect and induced DNA fragmentation which is hallmark of apoptosis in Colo320 DM and HSR cells. To elucidate the action mechanism of culture extract of No.2303, the effect of messengers of polypeptide growth factors on the anticaner activity of No.2303 was investigated. 12-0-tetradecanoyl phorbol-13-acetate(TPA) and dibutyryl cAMP(db cAMP) plus 3-isobutyl-1-methylxanthine(IBMX) were used as second messengers of growth factor because they act like diaclyglycerol(DAG) and cAMP respectivly inside of the cells. Anticancer activity and apoptosis induced by No.2303 were inhibited by treatment with TPA and db cAMP plus IBMX. These results imply that No.2303 induce anticancer activity by inhibiting c-myc expression and inducing apoptosis through pathway which involves the activation of protein kinase C(PKC) and protein kinase A.

가용성 난각막이 Fibroblast 세포의 증식 및 Type Ⅲ Collagen 생성에 미치는 영향

문순옥 수원대학교 기초과학연구소 1996 基礎科學論文集 Vol.5 No.-

In this study it has been demonstrated that egg membrane hydrolysate(EMH) is able to stimulate the proliferation of NIH 3T3 cells and increase the production of type Ⅲ collagen in NIH 3T3 and Malme-3 (human skin fibroblast) cells. The addition of EMH to quiescent NIH 3T3 cells resulted in an increase of proliferation which was assayed by MTT method. The maximum effect of EMH was detected in 0.4% EMH treated cells which was comparable to that of 5% serum (96% of 5% serum effect). The addition of EMH to NIH 3T3 and Malme-3 cells also increased the production of type Ⅲ collagen in both cells. These results indicate that EMH may enhance the repair process after injury and prevent aging processes in connective tissues.
