The Journal of the Korean Orthopaedic Association 1997;32(3):573-579
From Jan. 1987 to May 1994, we carried out cementless total hip arthroplasties using hydroxyapatite-coated Omnifit system, and among these, 63 cases in 49 patients were followed up more than 24 months. The average Harris Hip Score was 46.3 points preoperatively, 95.4 points at POD 1 year and 96.2 points at POD 2 years. Two patients (3%) complained thigh pain at POD 2 years. On the radiologic findings, endosteal bone formation was noted in 34 cases (53,9 %), radiolucent lines were seen at the non-coating region of distal stem in 41 cases (65.3%), which were less than 2mm and not progressive. Cortical hypertrophy was noted in 5 cases (8.4%), and calcar atrophy was observed in 31 cases (49 %).

OBJECTIVE: It has been reported that the sleep apnea syndrome in the asthmatic patients is prevalent, however, the systematic study in this field using polysomnography has rarely been performed. The aim of this study is to investigate the relationship between the apnea-hypopnea index (AHI) and the pulmonary function in asthmatic children. METHODS: This study enrolled 19 male and 12 female asthmatic children aged 6-13 years (average 8.2+/-1.7 years old). Complete overnight polysomnography and pulmonary function test were performed for the participants. RESULTS: Of the 31 asthmatic children, 21 (67.7%) met the diagnostic criteria of the pediatric sleep apnea and the average AHI was 1.7+/-1.5/h. The children with higher AHI showed poorer pulmonary function (FEV1/FVC ratio : p=0.002, FEV1%pred : p=0.047). CONCLUSION: These results suggest that the prevalence of the pediatric sleep apnea could be very high among the asthmatic children and the severity of the sleep apnea correlates with the pulmonary function. However, the case-control study to compare the AHI between the asthma and control groups is absolutely necessary because few normative data are available for the children.

Oguchi's disease is an unusual form of congenital stationary night blindness that is characterized by a peculiar grey-white discoloration of the retina that gives a metallic sheen. After prolonged dark adaptation, the unusual fundus discoloration disappeared and the retina slowly reverted to its original metallic color after exposure to the light. A 20-year-old man was referred for study because of a complaint of night blindness since childhood. As results of diagnostic work up, especially based on typical ocular fundus finding, dark adaptometry and electrophysiologic studies of the retina the authors have diagnosed as a Oguchi's disease. We report this case with the review of the literature.

BACKGROUND: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory repefusion disorders. We investigated the influence of cerebral repefusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. MATERIALS AND METHOD: Anesthetized Sprague-Dawley rats were undergone ligation of both infernal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of infernal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. RESULT: The histopathologic damage scores were 0, 10. 2+/-0.5, 7.6+/-1.5, 5.9+/-1.4, 5.0+/- 2.8, 3.5+/-0.7, and 1.0+/-0.0 in control, 0, 10, 20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). CONCLUSION: Our insults showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion know after incomplete forebrain ischemia. We believe restoration of repefusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

BACKGROUND: The increase of smoking prevalence in adolescents Is serious problem because of physical and psychological influences furthermore, fixation of smoking habit. This study is aimed at providing applicable basic information to setting up the education programs and strategies to prevent smoking among high school students by analysing smoking behavior and its related factors. METHODS: 835 students from one senior high school in Taegu completed a self administerd questionnaire during school hours in May, 1996. 813 questionnaires with adequate responses were analyzed using SPSS/PC program. All students were asked class years, school satisfaction, school performance score, number of their three best friends who smoke, smoking status of their fathers, religion, allowance, alcoholic drinks, addicting drug use, Zung's self-rating depression scale(SDS) and Zung's self-rating anxiety scale(SAS), Smokers were asked amount of smoking, motives for smoking, when they started smoking, Fagerstrom score. RESULTS: Of the 813 students in the sample 135(16.6%) were current smokers. About the amount of smoking, 59.3% smoked less than 5 cigarettes/day. About the motives of smoking, 34.8% started smoking through the solicitation by friends or for making friends. About when they started smoking, 52.6% started smoking before entrance into senior high school. The related factor with smoking Included class years, school satisfaction, school performance score, numbers of three best friends who smoke, allowance, alcoholic drinking, addicting drug use, SDS. Predictor of smoking were number of three best friends who smoke, number of alcoholic drinking, and allowance. The related factors of nicotine dependency were amount of smoking, allowance, when they started smoking. Predictor of nicotine dependency were amount of smoking, number of three best friends who smoke. CONCLUSIONS: The related factors with smoking included class years, school satisfaction, school performance score, number of three best friends who smoke, allowance, alcoholic drinking, addicting drug use, and SDS. Predictors of smoking were number of three best friends who smoke, number of alcoholic drinking, and allowance.

PURPOSE: Some women choose to undergo posterior colporrhaphy (PC) concurrently with procedures for SUI to regain sexual confidence and improve sexual function. We determine the effect of PC on sexual function in women requiring a midurethral sling for SUI. MATERIALS AND METHODS: A total of 119 women were retrospectively reviewed 81 women had the midurethral sling alone (Group A), and 38 women voluntarily had PC concurrently with the midurethral sling (Group B). Sexual function was evaluated using the FSFI before and after surgery. RESULTS: The postoperative composite scores were significantly increased in both groups (Group A: p=0.02; Group B: p=0.04), and significant increases were observed in 'desire,' 'arousal' and 'satisfaction'. However, there were no significant differences in the composite score or six domainscores between the two groups. CONCLUSION: PC performed concurrently with midurethral sling for treatment of SUI does not provide any additional benefits towards improving the sexual function.

Journal of Bacteriology and Virology 2015;45(3):256-261
The Bombyx mori decapentaplegic gene is one of the conserved genes in vertebrate and invertebrates. The TGF-beta superfamily contains conserved polypeptide growth factors that play important roles in different cellular processes such as proliferation, apoptosis, differentiation and cell-fate determination. The B. mori dpp gene shares genetic homology with hBMPs and Drosophila dpp. Until now, only few studies have been conducted to examine the functions of B. mori dpp; and hence, its function is not yet well understood. In this study, the baculovirus expression vector system (BEVS) was used for expression of the recombinant B. mori dpp protein and in which the recombinant baculovirus is recovered in the host Sf9 cells. The selected pure recombinant baculovirus containing B. mori dpp gene (rBV-egfp-Bm dpp) was used to increase the effective protein purification by using His-tag extraction strategy. After selection of recombinant baculovirus, recombinant B. mori dpp proteins were extracted from the re-infected cells with pure rBV-egfp-Bm dpp. Herein, we summarize the efficient expression and purification of B. mori dpp proteins from the insect cells using the BEVS. This recombinant protein could be suitable for functional test and various application studies.

Twelve cases of primary malignant lymphoma of the central nervous system experienced between 1980 and 1990 were investigated by histological and immunohistochemical findings correlated with clinical observation. Of the 12 patients, 6 were male and 6 were female. Their ages ranged from 31 to 58 years(mean, 45.8 years). All Tumors were supratentorial except 1 case which was found in the spinal cord. The fronto-parietal lobe was the most common site, which accounted for 66.7%. Histologically, all the tumors showed unfavorable histology. Diffuse large cell type was the most frequent(66.7%). Immunohistochemical studies using monoclonal antibodies revealed predominance of B-cell phenotype. Although most cases were treated with a combination of surgery and irradiation, the outcome was poor in all.

Journal of the Korean Society of Emergency Medicine 2000;11(3):339-344
BACKGROUND: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. MATERIALS AND METHODS: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4mg/kg) and atropine(0.01mg/kg) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. RESULTS: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5+/-2.4 min, and duration of action was 32.4+/-10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. CONCLUSION: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.
