An immunohistochemistry for S-100 protein by biotin avidin system technique was done to evaluate the existence and distribution pattern of S-100 protein positive cells in various obtained were as follows. 1) Positive immunostaining for S-100 protein was observed in myoepithelial cell, serous acinar cell and nervous bundle in normal salivary gland. 2) Strong immunoreactivity for S-100 protein was shown in plemorphic adenoma, which was localized not only in myoepithelial cord or sheets of epithelial portion but also in chondrocytes, stellate cells of myxoid stroma and in squamous keratin pearl of mesenchymal metaplastic foci. 3) The S-100 protein was demonstrated in the tumor cells of tubular adenoma, acinic cell tumors and in epidermoid area of mucoepidermoid tumors. 4) Immunoreactivity for S-100 protein, however, was not found in the tumor cells of adenoid cystic carcinoma and adenolymphoma except for stroma reticulum cells. 5) Intensity of positive reaction for S-100 protein varied from cell to cell: Some had intense immunoreactivity, whreas others were only weakly positive or completely negative, even in myoepithelial cell nest of the same pleomorphic adenoma.

PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

Korean Journal of Medical Education 2011;23(3):185-192
PURPOSE: Simple instructional systems design (ISD) model is based on a fast development, usability test, and continuos feedback, which are necessary for educational program development in medical school. This study aims to figure out the usability of Simple ISD model for a medical ethics education program by describing a developmental details of each phase and its evaluation results. METHODS: Research has been conducted in two steps. First, while researchers participated in the program development by using Simple ISD model, we collected empirical data of each development activities. Second, the developed program was evaluated by students' web-based usability test, a 8-students' focus group interview and 5 faculty members' individual interviews in 4 domains; learning contents, instructional methods and strategies, achievement evaluation, and self-evaluation. RESULTS: Following the circular process of analysis, design, development, and usability test of Simple ISD model, a 10-week medical ethics program covering 9 instructional topics was developed. The average points of response on the developed medical ethics program in 2008 and 2009 are increased from 3.96 to 4.59 and 4.41, respectively. The prospects and limitations of the program are discussed. CONCLUSION: From a development study of the medical ethics program by using Simple ISD model, we could implement a more usable medical ethics program, and found 4 different usability of the Simple ISD model; the rapid development of educational program, program improvement by continuous feedback, faculty members' engagement in instructional design, and professional development of the faculty members.

We report a 58 year old man who complained that his nails didn't grow for a year and developed yellowish discoloration. On physical examination his nails showed yellow greenish discoloration, increased corvexity, loss of lunulae and cuticles. C]iest X ray revealed atelectasis on right lower lung field and bronchiectasis on left lower lung field. Mild restrictive pattern was observed in pulmoniry function test. We gave him 800IU of Vitamin E claily for 3 months, but rio remarkable changes have been observed as yet..

PURPOSE: The purpose of this study was to determine the differences in the level of disease related knowledge, compliance of health behavior, and educational needs in relation to time (at discharge and 6 months after discharge) among patients underwent percutaneous coronary intervention (PCI). METHODS: Data were collected from January 1, 2006 to September 30, 2006 and a total of 60 patients participated in the study. The survey was conducted in patients underwent PCI at the time of discharge right after discharge education was provided and at a follow up visit which was 6 months after discharge. RESULTS: The level of disease related knowledge (p<.001), the compliance of health behavior (p<.001), educational need (p=.496), the sub-item of sexual life (p<.001), follow up (p<.001), diet (p=.021), stress (p<.001) in compliance of health behavior, and the sub-item of specific character of disease in educational needs (p=.015) were significantly different between discharge and 6 months after discharge. CONCLUSION: The results of this study suggested that further education should be provided to the patients underwent PCI regarding medication, smoking cessation, daily life and exercise at a time of 6 months after discharge in order to increase patient compliance of health behavior.

Clothing dermatitis is a rare disease. The distribution of the eruption coincides with the places on the skin where the garment fits most snugly. It is developed by the chemicals and the dyes rather than textile itself. We experienced 2 cases of clothing dermatitis, one of which was caused by formaldehyde in clothing.

10.The Studies of bcl-2 Oncoprotein and Epstein-Barr Virus Expression in Malignant Lymphomas: Immunohistochemical and in situ hybridization analysis on 66 cases.

Bcl-2 oncoprotein is being localized to mitochondria and interfering with programmed cell death (apoptosis) independent of promoting cell division in the lymphoid and nonlymphoid cells. The bcl-2 oncoprotein expression has been reported in follicular lymphomas as well as in diffuse non-Hodgkin's lymphoma, leukemia and a variable propotion of Hodgkin's lymphoma cases. Recent evidence suggests that some lymphomas protected from apoptosis is conferred through expression of Epstein-Barr virus(EBV) latent membrane protein which turn to cause upregulation of bcl-2. To define the role of the bcl-2 oncoprotein and EBV in lymphoid malignancy, we tried immunohistochemical studies with anti-bcl-2 antibody and In situ hybridization (ISH) with EBV-encoded small nuclear RNAs(EBER) in the paraffin embedded sections of 46 non-Hodgkin's lymphoma (NHL) cases and 20 Hodgkin's lymphoma (HL) cases. Bcl-2 oncoprotein expression was found in 37 of 46 cases (80%) of NHL with relatively strong cytoplasmic staining, and in 14 of 20 cases (70%) of HL with weak cytoplasmic staining in limited small numbers of RS, Hodgkin and lacunar cells. The widespread presence of bcl-2 oncogene in many different types of both NHL and HL supports that the extended cell survival through overexpression of bcl-2 gene protein may be a growth advantage of neoplastic lymphoid cells. In the ISH analysis for EBV, the presence of EBV was detected in 17 of 20 cases (85%) of HL, compared to 6 of 44 cases(13.6%) of NHL. It appears to be no direct correlation between overexpression of bcl-2 oncoprotein by neoplastic lymphoid cells and the presence of EBV in NHL but it seems to be a definite association between EBV and HL.
