The co-existence of mouth and genital ulceration with iritis was first defined as a syndrome by Behcet. It is now known to be a chronic and relapsing systemic disease, which involves many other systems. Neurogenic bladder dysfunction due to Behcet's disease, however, is extremely rare, and only a limited number of cases have been reported in the international literature. Voiding disfunction in Behcet's disease can be due to neurological or direct bladder involvement and can be related to bladder and sphmctehc components in both phases of micturition. We report on a 35-year old patient with a neuropathic bladder secondary to Behcet's disease.
두경부 편평세포암종에서 c-erbB 수용체, MMP 및 VEGF 발현
임성철 朝鮮大學校 附設 醫學硏究所 2005 The Medical Journal of Chosun University Vol.30 No.3
Head and neck squamous cell carcinomas (HNSCC) are characterized by a marked propensity for local invasion and cervical lymph node metastasis. The aim of this article was to review the expression of epidermal growth factor receptor (EGFR), c-erbB-2, vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) in HNSCC patients and to study their possible correlation to various clinicopathologic parameters. Based on this review, the expression of EGFR, c-erbB-2, VEGF, or MMPs play important roles for tumor growth, invasion and metastasis in HNSCC. c-erbB receptors, MMPs and VEGF might aid the clinician in theselection of an appropriate therapy for individual patients and help to predict the prognosis of patients.

Recently, The construction field in the urban area is short of working space and securing processing place because it is surrounded by adjacent buildings and nearby roads and have difficulties in rising labor costs. The insufficient space causes problems of interference and conflicts in transporting materials and working at the site. Therefore, Construction Manager find many alternative method and select industrialized method. The objective of this paper is to develop and give a method of information visualization system for manufacturing, delivering and lifting these materials in construction project stakeholders, using tools visualizing informations. The tools supports to stakeholders so many informations in material manufacturing, delivering, lifting in construction site. That is, order information, manufacture information in factory, sending information, carrying information, unloading and lifting in Site, and so on. Case studies are performed to evaluate the feasibility and applicability of the proposed method.

Background and Objectives : The purpose of this study is to determine whether human gastric adenocarcinomas express Fas-L, sFas-L or Fas , whether serum sFas-L leyel is changed in gastric cancer patients after gastrectomy, whether Fas-L expression is associated with increased apoptotic induction, especially, tumor-infiltrating Iymphocytes(TIL) and whether apoptotic induction is associated with the tumor stage and histologic type. Materials and Methods : The author analysed 38 cases of early gastric carcinoma(EGC) and 61 cases of advanced gastric carcinoma (AGC) which received gastric resection from 1997 to 1998. Of them, the number of diffuse type is 38 cases and the number of intestinal type is 61 cases. The author used immunohistochemical staining for Fas, Fas L and CD45, TACS^TM in situ apoptosis detection kit, and sFas ligand ELISA kit. Results : Fas-L was localized to neoplastic cells in 23 cases (23/38; 61%) of EGC group and 40cases (40/61; 66%) of AGC group. The extent of Fas-L expression was variable, with both Fas-L was localized to neoplastic cells in 23 cases (23/38; 61%) of EGC group and 40 cases(40/61; 66%) of group. The extent of Fas-L expression was variable, with both FasL-positive and negative neoplastic region cccuring within. TIL were detected by co-expression of CD4S and TACS on serial histologic sections. TIL adjacent to Fas-L erxressing tumor regions were decreased in number and TIL adjacent to FasL-negative tumor regions were increased in number; apoptotic induction of TIL showed the opposite pattern (p<05). Fas expression was found essentially homogeneously throughout the tumor mass independent of tumor stage. Fas expression showed 39 cases (39/61; 64%) of intestinal type and 26 cases (26/38; 68%) of diffuse type. Labeling indces for tumoral apoptosis in EGC and AGC were 6.72% and 7.13%, respectively and this difference was statistically insignificant. Co-expression of Fas-L and Fas, which occurred over large areas of the tumors, did not result in an enhanced rate of tumor cell apoptosis. The mean serum sFas-L level was significantly higher in patients before treatment compared with controls, whereas in post-gastrectomy patients, it was significantly lower, In addition, tumor stage and other prognostic factors were not associated with Fas and Fas-L expression, serum sFas-L level, number of TIL and apoptotic induction. Conclusion: 'The author demonstrates a statistically significant reduction of TIL concomitant with significantly increased TIL apoptosis adjacent to FasL-expressing regions of gastric adenocarcinomas. Also an elevated level of ·serum sFas-L in the gastric adenocarcinoma group was noted. These findings suggest Fas-mediated apoptotic depletion of TIL in response to Fas-L expression by stomach cancers, and provide the evidence to support the Fas counter-attack as a mechanism of immune escape in gastric cancer. And These findings indicate that the serum sFas-L level is a useful indicator in evaluating postoperative follow-up. In addition, gastric carcinoma cells of the intestinal and diffuse type did not differ in their expression of the Fas-apoptotic system.

복숭아나무 경지삽목 번식에 있어서 삽수 굵기와 길이 및 삽수내 저장 양분 함량이 발근과 포장활착에 미치는 영향을 구명하였다. 삽수 굵기는 直徑 5∼8㎜의 삽수가 발근율이나 발근수, 발근장 등 뿌리 발달이 좋았으나 포장 활착율은 삽수재 저장양분이 많은 직경 8∼11㎜가 좋았다. 삽수 길이는 20∼30㎝ 처리가 발근율, 발근수, 발근장 등 발근력이 좋았으나 포장 활착율은 삽수재 잔존 저장 양분이 많은 30㎝ 길이가 좋았다. 삽목용 적정삽수는 8㎜ 굵기에 30㎝ 길이가 가장 효과적이었으며 포장에서 활착후 묘고, 간경 등 생육은 모든 처리에서 116㎝ 이상, 20.4㎜ 이상으로 삽목 당년에 우량묘가 생산되었다. This experiment was studied to examine the effect of cutting size and storage nutrient on rooting and survival in field using hardwood cutting of 'Sunaga Wase' peach to establish mass production system of rooted cutting. Cuttings having 5 to 8㎜ in stem diameter showed the best rooting percentage, root number and root length. In the survival in field, the stem diameter of 8 to 11㎜ showed the highest survival rate and less consumption of storage nutrient during cutting. Those hardwood cuttings of 20 to 30㎝ in stem length showed the best rooting, and higher survival in field was obtained in 30㎝ long cuttings. After transplanting rooted cuttings to field, tree height and trunk diameter of 'Sunaga Wase' peach was 116㎝ and 20.4㎜, respectively.

CD24 is a small heavily glycosylated glycosylphosphatidylinosito-linked cell surface protein, which is expressed in hematologic malignancies as well as in a large variety of solid tumors, It appears to function as a ligand of PUselectin, an adhesion molecule that is present in activated platelets and endothelial cells. The authors aimed to evaluate CD24 protein expression in adenoma and adenocarcinoma of gallbladder to correlate to clinicopathologic data. The staining- was evaluated as stainability (negative, weak-, moderate-, strong-positive) and staining' patterns (membranous vs. intracytoplasmic) for statistical analysis. A highly significant association of cytoplasmic CD24 expression with adenocarcinoma compared to the adenoma of gallbladder was demonstrated. The present study demonstrates that CD24 was abundantly expressed on adenocarcinoma rather than on adenoma, but it was not statistically significant, Interrelation between the stainability or intracytoplasmic staining of CD24 and lymph node metastasis was not statistically significant. The authors conclude that CD24 is involved in tumorigenesis of gallbladder mucosa and intracytoplasmic expression of CD24 is an important molecular marker for malignant transformation.
