Epiblepharon is frequently encountered n oriental eyelid, especially in children. It is characterized by a horizontal fold of redundant skin and abundant orbicularis muscle near lid margin, which the lashes vertically, or posteriorly towards the eye. Surgical therapy of epiblepharon in correcting the trichiasis includes lid bracing sutures, burried sutures, skin resection, a Hotz procedure or its modification, and a Jones procedure. In our opinion, these procedures are not sufficient, because these procedures will not correct the epicanthal folds. Epicanthal folds have been a one of the characteristics of Asian over 50 percents of population in Japan and South Korea, and it either reduce the aesthetic result of the double-eyelid procedure or make the correction of the entropion and epiblepharon difficult. Although many surgical procedures are available to eliminate epicanthal folds, scarring on the medial canthus is in still and obstacle for surgeons to overcome. From January of 1998 to October of 1998, we used half z-plasty procedures in 5 cases to correct epicanthal folds in epiblepharon. There were few complications in our series. We believe that half z-plasty can get a good result in the correction of epibolepharon and oriental epicanthal folds.

PURPOSE: To analyze the association of visual efficiency and quality of life using data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V). METHODS: The present study included 5,244 glaucoma or glaucoma suspect subjects who completed a visual acuity test, visual field test and health-related questionnaire from the KNHANES V. Visual efficiency was calculated using best corrected visual acuity and visual field test. Quality of life was assessed with EuroQoL 5D (EQ-5D). Visual efficiency was compared with best corrected vision of the better eye to evaluate the relationship with quality of life. One-way analysis of variance (ANOVA) and partial correlations analysis were used to analyze the associations between factors. RESULTS: Both visual efficiency and best corrected visual acuity of the better eye were significantly different with all EQ-5D parameters (p < 0.005). After controlling for age, gender, income, education, spouse and house ownership, visual efficiency showed a positive correlation coefficient of +0.040 (p = 0.006) with the quality of life and the best corrected visual acuity of the better eye showed negative correlation coefficient of -0.044 (p = 0.002) with the quality of life. CONCLUSIONS: Visual efficiency was associated with the quality of life. Not only visual acuity but also visual efficiency would be a valuable parameter when considering the quality of life. Further studies are needed to evaluate non-glaucomatous populations.

7.Study on Nursing College Students' Subjectivity in Their Attitude Toward Jobs.
Journal of Korean Academy of Nursing 2005;35(4):680-685
PURPOSE: The purpose of the study was to categorize nursing students' subjectivity in their attitude toward their jobs, and thereby understand the differences among these attitude types. METHODS: The study used a Q-method to measure nursing students' attitude toward jobs identity types. In-depth and objective interviews and literature review formed Q sample. The P sample consisted of 25 nursing students. RESULTS: The results of the study show that nursing students can be categorized into three types, depending on their attitudes toward their jobs. The firs type, "interest-oriented" students, strongly disagree to the following: giving priority to job over marriage, standing unfair treatment in the workplace, the importance of promotion opportunity, irresponsibility, and uncertainty. The "reward-oriented" students, on the other hand, strongly disagree to the following: indifference to career prospects, employment-related relocation of residence, irresponsibility, standing difficulties, and compromises with others. The third type of nursing students is the possession-oriented students, who strongly disapprove of irresponsibility, refusal to compromise with reality, standing unfair job allocation or promotion and career uncertainty. CONCLUSIONS: The study on nursing college students' attitude toward their jobs is meaningful in the following aspects: First, the study clarifies nursing college students' attitudes toward their job by categorizing it. Second, the study confirms the changing attitudes of nursing students toward jobs with the change of times and calls for proper educational programs to foster healthy career attitudes. Third, proper decision-making as regards jobs and job allocation for nurses, or their career attitudes, is beneficial to individuals, the medical industry, and society.

PURPOSE: Recent studies have shown that cyclooxygenase (COX)-2 may be involved in tumor growth, invasion and apoptosis in various carcinomas. Vascular endothelial growth factor (VEGF) has a potent angiogenic activity, and COX-2 promotes angiogenesis by modulating angiogenic factors, including VEGF. Endothelial growth factor receptor (EGFR) is considered as a factor of cell growth, maturation and cell death. The current study was designed to investigate the possible roles of COX-2 in colorectal tumor progression and angiogenesis. METHODS: Fifty colorectal adenomas and forty adenocarcinomas were investigated by using immunohistochemical staining for COX-2, VEGF and EGFR. The correlations of COX-2, VEGF and EGFR with the grade of dysplasia, the size of the adenoma, and various clinicopathologic factors were studied. RESULTS: The expressions of COX-2, VEGF and EGFR were each significantly correlated with carcinomatous transformation, and the expressions of COX-2 and VEGF were significantly correlated. COX-2 and EGFR showed correlations with adenomas rather than adenocarcinomas. However, no correlations of COX-2, VEGF and EGFR expression to other clinicopathologic factors, except tumor size in EGFR expression, were detected. CONCLUSION: These results suggest that COX-2 may play an important role in carcinogenesis through interaction with VEGF and EGFR in human colorectal cancer.

BACKGROUND: Coronary artery target lesion calcification may be an important determinant of the arterial response to catheter therapy for coronary arterial disease. The excimer laser coronary angioplasty(ELCA) has been reported to be a promising treatment for complex coronary artery disease. However, the effects of ELCA is not well known against the calcified target lesion. METHODS: To assess the arterial and plaque remodeling in calcified lesions after excimer laser coronary angioplasty, we used a comprehensive intravascular ultrasound(IVUS) imaging system(25MHz rotation transducer, 3.9 Fr monorail imaging sheath, motorized transducer pull back at 0.5mm/sec and quantification) to study 23 patients(1 left main, 10 LAD, 4 LCX, 6 RCA, 2 SVG) before and immediately after ELCA(the AIS 308nm XeCl excimer laser, pulse width >200nsec, pulse frequency 20Hz, energy density 35-65mJ/mm2). Paired before and after ELCA image slices were analysed ; and extermal elastic membrane, lumen, plaque+media(P+M) and calcium cross-sectional area(CSA) measured; and their differences after ELCA calculated. RESULTS: The IVUS results about the therapeutic effects of ELCA showed the enlargement of lumen CSA from 1.5+/-0.4 to 3.2+/-0.9mm2(p<0.001) and decreased of P+M CSA from 14.6+/-3.8 to 13.4+/-3.6mm2(p<0.001) without arterial expansion. The decrease of calcium CSA from 1.8+/-0.7 to 1.5+/-0.6mm2(p<0.001) and the formation of small, superficial fissures within the calcified plaque(15/23 lesions) were noted. The number of small fissures correlate with the calcium CSA significantly(r=0.61, p<0.001). CONCLUSION: The plaque and calcium ablation is the main effects of ELCA in calcified lesion, and the calcium ablation and fissure formation after ELCA may contribute to decrease the dissection and improve the success after ajunctive PTCA.

OBJECTIVE: Taxol (paclitaxel)-induced apoptosis was studied to understand their biological mechanism correlated with the expression of p53 in the SKOV-3 and OVCAR-3 ovarian cancer cell lines. MATERIALS AND METHODS: The SKOV-3 and OVCAR-3 cell lines were cultured in RPMI 1640 medium without taxol (control group) and with taxol for 24 h and 48 h (experimental group). After harvest, the cells were stained with annexin V-FITC (fluorescein isothiocyanate) and anti-cytokeratin antibodies (clone CAM5.2 and clone MNF116). They were washed and stained with p53 antibody. After then the secondary antibodies, i.e., FITC- or phycoerythrin (PE)-conjugated goat anti-mouse (GAM) immunoglobulin G (GAM IgG-FITC or GAM IgG-PE) were added in the cells and they were incubated in the dark. DNA of these cells were stained sequentially with propidium iodide (PI). Standard FACScan equipped with a 488 nm single laser was used for the analysis of these cells. RESULTS: Both of SKOV-3 and OVCAR-3 cell lines were arrested in the G2M phase after treatment of taxol, suggesting that these cells would eventually enter into the stage of cell death. Fractions of negative cytokeratin and positive annexin V and amount of sub-G0G1 fraction indicative of apototic fractions were lower in the SKOV-3 cell line compared with that in OVCAR-3 cell line, probably as a result of lower sensitivity of SKOV-3 cell line to the taxol. p53 expression were not detected in SKOV-3 cell line. On the basis of observed findings in SKOV-3 cell line and findings of high expressions of p53 regardless of taxol treatment, no increases in their expressions according to culturing time, and gradual increases in sub-G0G1 fractions and in fractions of negative cytokeratin and positive annexin V indicative of apoptosis in OVCAR-3 cell line, we concluded that the expression of p53 would not be associated with cell cycle changes and the arrest in the G2M pahse but associated with the appearance of apotosis. CONCLUSION: Our results suggest that flow cytometric detection of the apoptotic fractions would be an effective, fast, and accurate method for the chemosensitivity test in tumor cells before the administration of anti-cancer drugs in gynecologic cancer patients.
