        씨름선수에서 체중 감량과 회복기의 Leptin과 PAI-1 변화

        김용운,도경오,권태동,박덕일,장응찬,박소영,김종연,이석강 대한스포츠의학회 2000 대한스포츠의학회지 Vol.18 No.2

        Obesity which is defined as accumulation of excess body fat, is central factor of insulin resistance syndrome. Recently, it is revealed tat adipose tissue is not simply an energy storage organ but it also secretes a variety of molecules which affect the metabolism of the whole body, those are leptin and plasminogen activator inhibitor-1(PAI-1). Therefore, leptin and PAI-1 are increased in the obese state. Leptin regulates energy homeostasis and satiety and PAI-1 regulates fibrinolytic system. For these reasons, elevated levels of leptin and PAI-1 are considered as link factors between obesity and insulin resistance syndrome. However, the exact regulating mechanism for serum levels of leptin and PAI-1 is not fully understood yet. In this study, to evaluate the regulating mechanisms of serum levels of leptin and PAI-1 according to the weight changes, we measured leptin, PAI-1, physical, metabolic, and endocrine parameters during 10 days of weight reduction and 10 days of regain period in 7 young athletes. The mean body weight change was -4.7 kg(5.0%) in the weight reduction period and -2.4 kg(2.5%) in the weight regain period compared to baseline value. Baseline level of leptin in athletes was 1.7±0.66 ng/ml, which was significantly correlated with body weight, BMI, percent body fat, body fat mass, triglyceride, insulin, and PAI-1. Baseline level of PAI-1 in athletes was 16.6±5.26 ng/ml, which was significantly correlated with body weight, BMI, triglyceride, insulin, and leptin. Leptin was decreased to 0.7±0.39(44% of the basaline value) in the weight reduction period, and increased to 1.9±0.64(119% of the baseline value) in the regain period. PAI-1 was decreased to 7.4±2.72(44% of the basaline value) in the weight reduction period, and increased to 22.8±7.33(138% of the baseline value) in the regain period. The changes of leptin during weight reduction period were significantly correlated with the changes of insulin(r=0.890, P<0.01) and triglycerides(r=0.874, P<0.01). The changes of PAI-1 during weight reduction period were significantly correlated with the changes of FFA(r=0.889, P<0.01) and triglycerides(r=0.869, P<0.05). The changes of both leptin and AAI-1 during weight regain period were significantly correlated with the changes of insulin(r=0.755 and 0.849, P<0.05, respectively). In summary, these results suggest that serum levels of leptin and PAI-1 were affected by weight cycling, the percentages of change were more greater than that of weight change, and rebound phenomena were occurred during weight regain period.

        We analyzed records at Chonnam university hospital from Sep. 1. 1993 to Aug. 31. 1996 to assess clinical significance of the foreign body in the gastrointestinal tract. There were 133 episodes consisting of 79 pediatric and 54 adult patients as possible to review. In the pediatric patients, the coin was the most common cause of foreign body ingestion, while adult patients were usually caused by bones and meat. We removed foreign bodies in the oral cavity and oropharynx in 12 cases using direct laryngopharyngoscpy and forcep. Endoscopy was performed successfully in 47 of 51 patients in which was attempted; there were two complications composed of an aspiration pneumonia and a mediastinitis due to esophageal perforation. There were spontaneous passage of foreign bodies in 48 cases. We observed complications in 6 cases in which 4 cases needed operations due to complications. Foreign bodies which pass into the stomach can be observed for development of complications, as 94% of foreign bodies which reach the stomach spontaneously pass. Only 4 patients required interventions, which was done without mortality.

        This study examined the running patterns of deep fascia around muscles in a human cadaver. After the skin and superficial fascia were removed, the holistic fascia arrangement was investigated with the naked eye. In order to make an observation, the interconnection of fasciae on both sides and muscles were lifted. To make an estimation of running direction and tension of the subject fasciae of each body part, epimysium along with muscle fibers of the subject muscles were held and lifted with tweezers. The running direction and tension correlation of the deep fascial fibers were observed parallel to the muscle fibers of the subject muscles. In the back, four rhomboid shape fascial profiles were observed around the vertebral column. The rhomboid profiles are composed of a fascia of trapezius, a fascia of latissimus dorsi, a fascia of Michaelis rhombod, and an innominated rhomboid, which were located between a fascia of trapezius and a fascia of latissimus dorsi. Upon observation of the connection of fascial fibers, they appeared with a thin and loose formation between muscles, appeared with a thin and dense formation between a muscle and soft tissue around the bone, and appeared with a thick and loose formation between muscle groups.

        The Certification Authority in each country is briskly in progress to get the reliability of Electronic Commerce. One Certification Authority can not authenticate the reliability of Electronic Commerce spreading itself to the world rapidly. Therefore, Each country is constructing the base of Electronic Commerce Authority System and trying to provide cross connection with compatibility through the Cross-Authentication. This paper analysed the requirements of Cross-Authentication Mechanism on researching internationally and proposed the check-list of Cross-Authentication Model. The paper could be a guidance to organize domestic Cross-Authentication System Models.

        Most industries have several projects to undertake which fall into the category of capital investments. But the general tendency of their economic analysis has been confined to a project by project basis. This tendency made it very difficult to configurate overall possible impacts upon the value of a firm, and upon the future financial structure that may be produced from the performance of a certain set of selected project alternatives. This thesis attempts to resolve these shortcomings by adopting the concept of integrated management information system. For this purpose a data base schema was constructed to facilitate the systematic processing of capital investment information. From the cash flow information a desirable debt ratio (DDR) was determined to find the amount of debt that can be financed to each project under specified risk level. The DDR model, when applied with the 0-1 integer programming model, plays an important role in the selection of optimum project-mix that will keep the firm in healthy financial position throughout its planning horizon. Another important achievement from this study is that it was made possible to derive various kinds of expected financial ratios over the forthcoming time domain of top management's concern, while the conventional financial ratio analysis has been restricted to the past.
