The reduction of nasal bone fracture has been done by a simple procedure. The nasal bone fracture was not a serious problem and patients are usually treated as outpatients. However it is causing increased demand for medical services far cosmetic reasons. We studied the nasal bone fracture by retrospective analysis, it comprising 606 patients with nasal bone fractures in various accidents and treated of Chonnam University Hospital from March 1995 to February 1998. We reviewed and analyzed the medical records and facial bone CT scans of 606 patients. The following results were obtained. 1. The prevalent age group was in the third decade, the most common cause was traffic accidents, while nasal swelling, tenderness, nasal deviation and crepitation were examined 2. The classification of nasal bone fracture was done by facial bone CT. Class 1: Nasal tip depressed fracture(16%) Class 2: Displaced nasal bone fracture without depression(30%) Class 3: Displaces nasal bone fracture with depression(12%) Class 4: Comminuted nasal bone fracture (10%) Class 5: Simple fracture of nasal bone and frontal process of maxilla(14%) Class 6: Comminuted fracture of nasal bone and frontal process of maxilla(11%) Class 7: Nasal bone fracture without displacement(9%) .

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.

Lichen nitidus(LN) is an unaommon chronic eruption of numerou tiny, discrete, usually flesh colored, shiny papules most cornmonly located on the penis, arms, for arms, and abdomen. It was described by Pinkus, first in 1901. The distribution of LN is most often locaized, but in some cases it may become generalized. A 10-year-old healthy boy was seen by our department because of many flesh colored, discrete, shiny papules on the whole body. The papules are skin colored, pinhcad sized, round, and flat-topped. The lesions appeared first at the age of 9 on the forehead and then neased in the number and extended downward to the neck, trunk, abdornen and both extremities. This case was successfully treated with topical corticosteroid.

BACKGROUND: Melanocytes synthesize melanin pigment by the action of specific enzyme tyrosinase. Melanogenesis inhibitors such as ascorbic acid, kojic acid, arbutin, hydroquinone have been developed for use in cosmetic preparations for the skin hyperpigmentation,but they are still unsatisfactory to efficacy and tolerance. OBJECTIVES: In this study, the inhibitory effects of seaweed extract(SCH-T2)on tyrosinase activity and melanogenesis were investigated with B-16 melanoma cell line. METHODS: The patients were randomly assigned to one of three groups;control, diazepam, and ketorolac plus diazepam groups. Pain intensity was assessed 5 times at every ten minutes from the beginning of the peeling using visual analog scale(VAS). RESULTS: The seaweed was added with 21 organic solvents and extracted during 12 hours at 20-To evaluate the inhibitory effects of SCH-T2 on tyrosinase activity following to extraction time and temperature, this study was done at 4, 8, 12, 24, 72 hours and 4, 10, 20, 30, 40℃. Also, the effects of whitening agents (kojic acid, arbutin, licorice extracts,SCH-T2)on tyrosinase activity were compared by measuring the IC50,the concentration of the compound at which half of the original tyrosinase activity is inhibited. RESULTS: 1.The inhibitory effects of SCH-T2 on tyrosinase activity were high at 60-80% ethanol as an extraction organic solvent and showed increase in proportion to concentration following to extract concentration, but showed little differences following to extraction time and temperature. 2.SCH-T2 has relatively stronger inhibitory effects on tyrosinase activity than arbutin and licorice extracts. 3. The inhibitory effects of SCH-T2 on melanogenesis following to extract concentration were greatly increased at more than 20㎍/ml. CONCLUSION: This study showed that SCH-T2 seaweed extract has strong inhibitory effect on tyrosinase activity and melanogonesis. So, the results of this study suggest that SCH-T2 seaweed extract can be used as a new whitening agent.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.
