Rhinocerebral mucormycosis is a well-described fulminant fungal infection that typically presents in a rapidly fulminant manner. This condition is more likely to occur among patient with diabetes mellitus, malignant tumors, who have long-term steroid treatment, or who suffer from some debilitating diseases. We report 3 cases of rhinoorbitocerebral mucormycosis, all suffered from diabetes mellitus. In all 3 cases, endoscopic sinus surgery was done and the antifungal agent(amphotericin B) was administered intravenously, and two patients died. One survivor who had focal extension of paranasal sinus and orbit, required one surgical intervention without orbital exenteration and he is alive without recurrence disease. The severity of the disease is probably dependent upon the gost resistance to the invasion of phycomycetes. Early diagnosis and immediate, effective treatment are the key for cure of the disease.

文順玉 수원대학교 산업기술연구소 1991 산업기술연구소논문집 Vol.6 No.-

Screening method for the isolation of anticancer molecule from microbial extract was entablished by using sulforhodamine B(SRB) assay, Hep-2 and PC14 cell lines which were derived from human epidermoid carcinoma and prostate adenocarcinoma respectively. The effect of cell number on SRB assay showed the absorbance is proportional to cell number. The growth rates of cell lines were determined using the SRB assay. These results can be used for the optimization of screening test. Primary screening test showed that extracts of Actinomycetes isolated from soil have cytotoxic activity to PC14 and Hep-2 cell lines.

This paper presents the navigation method for a mobile robot which uses a single camera and fluorescent lamp as a guide mark, projected on a convex mirror. The current position and heading direction of the mobile robot are obtained from the image of the guide mark. While the mobile robot travels to a goal position, the current position and heading direction of the mobile robot are updated continuously and the desired path and actual moving path are displayed on the monitor screen in real time. This proposed method eliminates the need to rotate the camera to track the guide mark, since a panoramic view of the surrounding area is available from the convex mirror, and natural guide marks such as usual florescent lamp on the ceiling or door frame can be used for navigation.

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

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.

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.

Renal ischemia is one of the most common causes of acute renal failure. Four factors related to the pathogenesis of acute renal failure are vasoconstriction, decreased glomerular filtration rate, tubular back leak of filtrate, and intratubular obstruction. The cellular response to renal ischemic insults include decreased content of adenosine trihosphate, lipid peroxidation induced membrane degradation, alteration in cellular pH, and calcium or phospholipase induced mitochondrial dysfunction. Much attention has been given to the role of increased cellular calcium as a pathogenetic contributor to cell injury during ischemia. Author studied the protective effects of calcium antagonists on cellular injury during renal ischemia in rat. To investigate the protective role of these agents, author measured the amount of malondialdehyde(MDA) and the enzyme activities of free radical scarvengers-superoxide dismutase(SOD), catalase and glutathione peroxidase from non-pretreated group and calcium antagonists pretreated groups in control, ischemia and reflow subgroups. The results were summerized as follows: 1) The amount of MDA in non-pretreated group was higher in the reflow compared with the control(<p<0.01). But, in all pretreated groups, there was no statistically difference in the amount of MDA. 2) The SOD activity in non-pretreated group was lower in both the ischemia and the reflow compared with the control (P<0.05). But, in both verapamil and trifluoperazine-pretreated groups, there was no statistically difference in the SOD activity. 3) Both catalase and glutathione peroxidase activities in non-pretreated group were lower in both the ischemia and the reflow compared with the control (P<0.05). But in all pretreated groups, there was no statically difference in both catalase and glutathione peroxidase activities. These results suggest that free radical mediated ischemic injury by renal artery clamp in rat can be protected by intraperitoneal pretreatment with calcium antagonists. As trifluoperazine has a protective effect in renal ischemia, the calcium activated calmodulin dependent enzyme may play a role in renal ischemic injury.

구조도면 자동생성 프로그램 개발에 관한 연구

문연준,김순철 東新大學校 2003 論文集 Vol.13 No.-

Last products of architectural engineering can divide into structure calculations and designs. Structural calculations and designs are using because a lot of common use programs are developed, but automatic drawing is not available. And data that is used in structural analysis is not used in drawing creation process and a lot of time and efforts are required to all of the engineers and architectural designers. Also, because primary engineer is taking charge of this, many mistake of drawing creation are made. Automatic drawing can enhance engineer's productivity and company's competitive power in construction market in the era of globalization. Therefore, in this research, I developed structure drawing automatic creation program by VB (Visual Basic) that is used recently among automation method and appled to sample model. By using this program, we can make automatically and quickly analyze and design without any mistakes.

This study was conducted to evaluate the elements affect on the quality of red ginseng. For that purpose, we surveyed the relationship between the red ginseng quality and the properties of material ginseng, processing methods, root year, root size, production location, and cultivation methods. Six-year old raw ginseng caused higher inside cavity than younger one did and larger sized ginseng increased outside cracking and inside cavity but decreased inside white than smaller sized one did. The production location did not affect the quality of red ginseng. The red ginseng processed with the ginseng grown on upland field showed lower outside cracking and inside cavity than the red ginseng processed with the ginseng grown on paddy field did. In terms of cultivation method, transplanting method showed lower inside cavity and inside white rates than direct sowing method did. In conclusion, ginseng cultivation location and cultivation method affected on the quality of the red ginseng more than the root age, root size and production location did.
