The double eyelid operation is one of the most common cosmetic surgery performed in orientals, and there are numerous studies about surgical procedures of that. In the case of appropriate candidates, the non-incision technique makes excellent cosmetic results, with the advantages of shorter operating time, less morbidity, less pain, no scarring and easy revision of shape. But, usually the non-incision technique is recommended in the cases with thin upper eyelid, small amount of orbital fat, less redundant skin of upper eyelid and in whom a wide fold is not desired so on. Therefore, the disadvantages of this method are that it cannot be applied to all patients. The postoperative complications are disappearance or faded fold, formation of cyst or lumps, asymmetry etc. and the incidence of these complications is slightly higher than those of the incisional method. In this study, the double eyelid operation using the continuous buried suture method was performed in 210 patients for formation of double eyelid from Jan. 1993 to Dec. 1995. In conclusion very good results can be obtained by the continuous buried suture method even in the cases of puffy upper eyelid. This method can make a double eyelid shape in the fashion the patient wants and can be a new indication for correction of unilateral double eyelid. This method is safe, satisfactory and take shorter postoperative recovery time and it can reduce the incidence of postoperative complications.

Fluoride is one of the most potent stimulators of bone formation in vivo. But its direct effects on osteoblast is not yet clear. This study was to investigate the effects of Sodium fluoride on alkaline phosphatase(ALP) activity, cAMP formation responsive to parathormone(PTH) and type I alpha 2 collagen ribonucleic acid (mRNA) level in Murin osteoblast-like (MC3T3-E1) cells. The cells were cultured in alpha -Minimal essential medium ( alpha -MEM) supplement with 10% fetal bovine serum (FBS) and then changed to 0.1% FBS with various concentration of Sodium fluoride. The ALP activity was assayed by the method of Lowry with disodium phenyl phosphated as substrate. cAMP formation was measured by Radioimmuno Assay(RlA). Type I alpha 2 collagen ribonucleic acid(mRNA) expression was studied by Nothern blot analysis. The results were as follows: 1. cAMP level was increased by PTH in MC3T3-E1 cells. 2. Sodium fluoride showed the tendency of inhibitory effects on cAMP responsiveness to PTH in MC3T3-E1 cells. 3. Sodium fluoride increased ALP activity at cocentration of 2micrometer, 4micrometer, and 10micrometer significantly different from control at the 0.001 level. ALP activity revealed maximum value at 10micrometer in this study. 4. Nothern blot analysis of Sodium fluoride treated cells, using Type I alpha 2 collagen prove, revealed significant increase at 10micrometer in MC3T3-E1 cells.

PURPOSE: We wanted to clinically evaluate the antibiotic therapy used from pre- to postlaparoscopic cholecystectomy along with the improved surgical techniques and instruments and the patient nutrition. METHODS: We prospective studied 105 patients who were treated with laparoscopic cholecystectomy for acute and chronic cholecystitis at Busan St. Mary Hospital from March 2007 to January 2008. The two groups were divided as follows: (A) the group was not injected with antibiotics, and the other group (B) was injected with antibiotics. We did not used antibiotics when the patient had no acute aggravating symptoms, and we exclude the patients with old age (<70 years), a past history of diabetes mellitus (DM) or hypertension (HTN), and a past operation history. RESULTS: Between the two group, there was no difference when they were compared for age, BMI (Body Mass Index), the operation time (minute) and the length of the hospital stay: (A) Group 49.3+/-13.0 years, 24.4+/-3.2 kg/m2, 37.9 +/- 10.0 minute and 4.6 +/- 1.3 days, respectively, and (B) Group 55.9+/-15.6 years, 23.5+/-3.5 kg/m2, 43.2 +/- 23.8 minute and 5.5 +/- 2.5 days, respectively. There was a significant different in the leukocyte count and the % of neutrophils: (A) Group 6396microliter(-1) and 53.4%, respectively and (B) Group 9354microliter(-1) and 66.6%, respectively. In (B) group, there were 2 cases of atrial fibrillation, 1 case of diarrhea and 1 case of wound seroma. There were no surgical related complications in group (A). CONCLUSION: For the well nourished chronic cholecystitis patients, the use of the prophylatic antibiotics may be less effective because of the many drug-induced side effects. More studies about the use of prophylactic antibiotics are needed.

OBJECTIVES: Although the mechanisms underlying the initiation and maintenance of inflammation in unilateral maxillary fungal balls (FBs) are poorly understood, the relationship between intranasal anatomy and maxillary FB is thought to play an important role. The aim of this study was to investigate the relationship between anatomic variations and FB. METHODS: We enrolled 140 patients who were composed of 56 patients with FB, 56 patients with unilateral chronic rhinosinusitis (CRS), and 28 patients with no sinus disease. Computed tomography scans were retrospectively analyzed to identify and compare the associated nasal anatomic abnormalities. To measure the volume of the nasal cavity and middle meatus, computed tomography scans were reconstructed into three-dimensional images. RESULTS: The relatively larger volume of the middle meatus was associated with the localization of the FB in contrast with the CRS. However, the nasal-cavity volume, nasal valve area, and nasal septal deviation were not significantly associated with localization of FB. The mean volumetric and areal measurements such as nasal cavity, middle meatus, and nasal valve in FB-ipsilateral sides were not significantly different from those in contralateral sides as well as other groups. CONCLUSION: The middle meatus bears the major part of the inspiratory nasal airflow, and its volume may influence the occurrence of FB.

PURPOSE: The purpose of this study was to explore the differential effects of multi-dimensional perfectionism on academic achievement, depression, engagement, and burnout in medical students. Also, the mediating effects of engagement on perfectionism and academic achievement, as well as the effects of burnout on perfectionism and depression, were examined. METHODS: Two hundred eight medical students participated, and 167 students completed questionnaires, including the Frost Multi-dimensional Perfectionism Scale (FMPS), Hewitt & Flett Multi-dimensional Perfectionism Scale (HFMPS), Beck Depression Inventory (BDI), Schaufeli Engagement Scale (SES), and Malslach Burnout Inventory-General Survey (MBI-GS). Academic achievement was measured as the grade point average (GPA) of the previous semester. Data were analyzed by correlation analyses, independent t-tests, and Structural Equation Model (SEM) for path analysis. RESULTS: Adaptive perfectionism (personal standard, self-oriented perfectionism) was associated with GPA (r=0.164, p<0.05; r=0.173, p<0.05) and engagement (r=0.394, p<0.01; r=0.449, p<0.01), and maladaptive perfectionism (parental criticism, concern over mistakes, socially prescribed perfectionism) was associated with depression (r=0.208, p<0.01; r=0.254, p<0.01; r=0.234, p<0.01) and burnout (r=0.218, p<0.01; r=0.236, p<0.01; r=0.280, p<0.01). Engagement had mediating effects on adaptive perfectionism and GPA, and burnout had mediating effects on maladaptive perfectionism and depression. Students who experienced academic failure had lower engagement than those who did not. CONCLUSION: This study demonstrates that academic achievement and emotional difficulties such as depression are determined by adaptive and maladaptive perfectionism, respectively, in medical students.

Epidermoid tumors of the central nervous system are infrequent(2%) and can occur congenitally or iatrogenically. Since Choremis et. al. reported intradural-extramedullary epidermoid tumor after repeated lumbar puncture, several cases have been reported. We experienced a case of epidermoid inclusion cyst after single lumbar puncture in a 7-year-old boy and report the clinical and radiologic findings with relevant literatures.

The number of wild animal species is gradually decreasing due to poaching, hunting and habitat loss. While several endangered animal species have been successfully preserved at the zoo, assisted reproductive technology (ART) must be applied to restore wild animals. In the case of critically endangered animals, somatic cell cloning is considered the most appropriate method of ART. Somatic cell cloning can be beneficial for the reproduction of endangered species with limited female populations. However, gene and cell banks, and understanding of reproductive physiology and optimization of ART for wild animals are urgently required for further activation of artificial reproduction of endangered species, which enlarges its application and maintains biodiversity. Care should also be taken to consider ethical and legal issues associated with somatic cell cloning for conservation of endangered animals.

Clinical and endoscopic features on 86 patients with acute upper gastrointestinal mucosal lesien were evaluated. Males were predaminant about 3 times of female. Most of patients were in 4 th to 6 th decade. The prevalent locations were proximal part of the stomach and dodenal bulb. Most,freqent chief camplaints was epigastric pain. Eeloscopieally aoute ulcers were characterized by shallow in depth, variant size and shape, rather clear ulcer margin without mucosal fold eonvergence and multiple lesions rather than sigle. The inducing factors of the acute mucosal lesiona whiah were noted were alcohol, HCI, analgesics, herb drug, steroid, antibiotlies and orgaaie ipheephorus.
