The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

Commercial building of small-medium scales in korea are being developed by multiple aspects. Commercial building of small-medium scales are lacking in representation of commercial function and characteristic image of their own. Therefore, the representation of commercial function is substitutes by many billboards and signboards and the visual street environment has been going from bad to worse. Planning of exterior renovation must include the representation of commercial function and the representation must be formed by architectural methods. Representation of commercial buildings means that communicational function of architectural and identity of architecture. The result of this study are as follows. The methods of Double skin and hybrid of surface and using new material on surface and wall is effective and economical methods to increase the representation of commercial function.

Primary aldosteronism is a syndrome characterized by hypertension, hypokalemia, suppressed plasma renin activity, and elevated serum aldosterone levels. Conn first described it 1955 in association with adrenal cortical adenoma(Conn's syndrome). Today, it can be divided into at least six distinctive sub-groups. The diagnosis of primary aldosteronism is usually suspected when the patient presents with poorly controlled hypertension with hypokalemia. The main issues in the evaluation of primary aldosteronism are to differentiate an adenoma from hyperplasia and to localize the adenoma. Basic hormonal studies and computed tomographic(CT) scanning can be used effectively for that differentiation. An adenoma is one of a few potentially curable forms of hypertension, and it is best treated by removing the adrenal tumor. We experienced a case of a typical adrenal adenoma. The patient was a 37-year-old male who had experienced in both his legs over a period of several days a weakness due to hypokalemia. He was diagnosed using basic hormonal studies and adrenal CT scanning. After, he received laparoscopic adrenalectomy and was discharged with improved condition.

There are many causes of trismus. Aetiology can be roughly divided into muscle spasm, mechanical interference, extracapsular ankylosis, intracapsular ankylosis. Trismus caused by mechanical interference between postero-lateral wall of zygoma-maxillary complex and coronoid process following reduction of fractured facial bone is rare. Especially on maxillary bone fracture, when we faced the trismus following removal of intermaxillary fixation, we got used to solve that problem by physical exercise, We obtained good resurts by coronoidectomy on patients with limited mouth opening who were referred from department of plastic surgery, St. Marys' hospital, the Catholic university of Korea. We report our experience with literature review.

성장기 골격성 Ⅰ급 부정교합 환자의 정모두부방사선 계측의 특징

성상진,문윤식,김정국,정현성 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.2

악안면 기형과 부정 교합의 성공적인 교정 치료를 위하여 안모의 3차원적인 평가가 필수적이지만 교정의사는 주로 측모두부방사선사진에 기초한 진단 및 치료계획에 익숙하다. 이는 정모두부방사선사진에 관한 계측치, 악골의 폭경 성장에 관한 지식과 임상적 의의에 대하여 관심이 부족한 때문으로 생각된다. 본 연구에서는 골격성 I 급 부정교합으로 진단된 6세에서 16세 사이의 남자 130명과 여자 171명을 대상으로 정모두부방사선사진 상의 두개골 및 상하악골의 폭경을 계측하여, 연령과 경추골 발육지표(CVMI)에 따른 변화 양상을 알아보았다. 다항 회귀모형(polynominal regression models)과 변수선택법(method of variable selection)을 이용하여 적합한 회귀모형(regresslon model)을 각 성별에서 선택하고 이를 이용하여 연령에 따른 각 계측치의 평균 및 개별 계측치(individual measurement)의 70% 신뢰구간(confidence interval)을 추정하여 그래프로 작성하였으며, 다음과 같은 결과를 얻었다. 1.모든 폭경 계측치는 나이 또는 CVMI의 증가에 따라 점차 증가하였으며,6세부터 16세까지의 총변화량은 상악골 폭경보다는 하악골 폭경이 그리고 여자보다는 남자에서 더 많은 경향을 나타내었다. 2.Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio는 연령과 CVMI에 따른 남녀간의 유의차가 없었다. 3.회귀모형을 이용하여 나이에 따른 남녀 계측치의 평균 및 신뢰구간을 70%로 추정하여 상악골폭경,하악골 폭경, Mx-Mn difference, Mx/Mn ratio에 대한 그래프를 얻었다. 4.한국인의 상하악골 폭경은 성장기 동안 서양인에 비하여 큰 경향을 나타내었다. 본 연구의 결과를 성장기 부정교합 환자의 폭경 성장 평가와 폭경 부조화의 진단에 이용한다면 치아 석고모형 만을 이용하는 한계를 적절히 보완할 수 있다고 생각된다 Three dimensional analysis of malocclusion and craniofacial deformation is essential for the successful orthodontic treatment. But the orthodontists are not familiar with diagnosis and treatment plane based on lateral cephalometric analysis. Since orthodontists do not posses a sufficient knowledge in standard value of posteroanterior cephalometric analysis and of clinical importance for transverse jaw growth. In this study male(n=130) and female(n=171) aged from 6 to 16 and diagnosed as Class I malocclusion were selected to analysis width of cranium, maxilla and mandible on the posteroanterior cephalogram. The changes as a function of chronologic age and cervical vertebrae maturity index(CVMI) were examined. The proper regression model was selected by sex with polynominal regression models and method of variable selection. Mean of each measurements and 70% confidence interval of individual measurement according to age was assesed and a graphs were made. Results are as follows : 1.All the measurements for the width are gradually inclesed as increase in chronologic age and CVMI. From the total amount of change between age 6 and 16, there is a tendency that mandibular width is broader than maxillary width and the width of male is broader than female. 2.There is no statistically significant sexual difference in Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio according to age and CVMI. 3.Mean of each measurement and 70% confidence interval of individual measurement according to age and sex were assessed and graphs were made for maxillary width, mandibular width, Mx-Mn difference, Mx/Mn ratio. 4.The width of maxilla and mandible in Korean children are broader than Western children during growth period.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.
