  • Halophytes have been reported to possess a variety of physiological activities, such as anti-cancer, anti-oxidant, anti-diabetes, anti-inflammatory, and anti-obesity. Studies on the roots of the halophyte Rosa rugosa, in particular, have shown a variety of physiological activities and are known to be effective for nursing diabetic complications in traditional Korean medicine. In this study, the effect of R. rugosa on adipogenesis was investigated in 3T3-L1 pre-adipocytes treated with crude extract and solvent fractions (H2O, n-BuOH, 85% aq. MeOH, and n-Hex) obtained from R. rugosa roots. Treatment with extract and the solvent fractions inhibited the formation of intracellular lipid droplets in differentiated 3T3-L1 adipocytes compared to the untreated group. In particular, n-BuOH and 85% aq. MeOH fractions effectively decreased the expression of adipogenic transcription factors: peroxisome proliferator activated receptor-γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), and sterol regulatory element-binding protein 1c (SREBP1c) in both mRNA and protein levels. In conclusion, these results suggest that R. rugosa contains anti-adipogenic molecules that can be utilized as a nutraceutical against obesity. Further refining of n-BuOH and 85% aq. MeOH fractions and analysis of their action mechanisms could yield potential therapeutic agents with anti-adipogenic effects.

  • The purpose of this study was myokine product and role with physical activity and literature review. There is accumulating epidemiological evidence that a physically active life plays an independent role in the protection against type 2 diabetes, cardiovascular disease, colon cancer, dementia and even depression. And myokine has been regarded an important factor of exercise training and brain growth factor for the prevention of Alzheimier's disease. During exercise the release of anti-inflammatory myokine from contracting muscle controled the metabolic response, and IL-4, IL-6, IL-7, IL-10, and IL-15 controled muscle hypertrophy, myogenesis and angiogenenesis. IL-6 promoted the lipid metabolism through AMPK activation. IL-1Ra, IL-10 and sTNF-R inhibited $TNF-{\alpha}$ as the pro-inflammatory cytokine. IL-15 increased the releasing volume from contracting muscle, and promoted the anabolic factor of muscle growth. IL-7 and IL-8 activated the angiogenesis through the more activation of C-X-C receptor signal transmission.

  • Paragonimiasis is the infestation of lung flukes of the trematode genus Paragonimus. This disease is common in Asia, and the southern part of Korea has been known as one of the endemic areas of Paragonimiasis westermanii in Korea. Human infection is associated with specific dietary habits, such as eating freshwater crawfish or crabs. In a 6 1/2-year-old boy with pleural effusion and eosinophilia, paragonimiasis was diagnosed by skin test, serologic exam, and histologic identification of the parasites in a skin lesion. The same diagnosis was entertained in his elder sister with silent pleural effusion. We describe herewith these rare cases of paragonimiasis in two siblings who had a history of eating cooked freshwater crabs.

  • The aim of this study was to investigate the effect of combine exercise on the fall injury related index and myokine in elderly women. Sarcopenia leads to a loss of strength, alter on to a decreased functional status, impaired mobility, a higher risk of falls, and eventually an increased risk of mortality. Aerobic exercise characterized by rhythmic and repetitive movements of large muscles, for sustained periods that depends primarily on the use of oxygen to meet energy demands through aerobic metabolism, and that is structured and intended to generate improvements in cardiopulmonary fitness, body composition, and cardiorespiratory health. Resistance training has performance in the elderly. As combined exercise therapy can be used to enhance muscle functions and cardiopulmonary functions, it is being highlighted as an effective health management methods for the aged. The myokine has been regarded an important factor of exercise how muscle communicate adipose tissue, bone and muscle to exert beneficial effects at the whole body level.

  • A case of cutaneous leishmaniasis developed in a 48 year old Korean male who returned from middle east was studied by light and electron microscopic observations. Light microscopically, the lesion consisted of heavy chronic ill-defined granulomatous inflammation involving entire thickness of the dermis, composed of mainly histiocytic and small mononuclear cell infiltrations without evidence of necrosis or giant cell formation. Giemsa staining revealed numerous intracellular micro-organisms within histiocytes, showing dark stained central dot surrounded by light stained cytoplasm. Electron microscopically, the organisms were observed mostly ovoid in shape and frequently binary mitotic features within the host cells. follicle consisted of double unit membranes and microtubules, which are immediately below these membrnae. A long kinetoplast was noted within a very elongated mitochondrion at the center of the organisms and a flagella rose in front of the kineoplast but ended within the cytoplasm. Large numbers of free ribosomes, occasional Golgi complex and SER were also noted, but RER was seldom found. These ultrastructural features corresponded to promastigote stage of Leishmania tropica. In principle, leishmaniasis is a tropical disease and can not be found in temperate zone. However, travel to mideast by many Koreans may contract this disease while they are in endemic regions.

  • Purpose: X-linked adrenoleukodystrophy(ALD) is a rare disorder that shows a great deal of phenotypic variability. We subdivided chidhood X-linked ALD patients into several phenotypes by the age at onset, the sites of most severe clinical involvement and the rate of progression of neurologic symptoms. Methods: Thirteen patients who had been diagnosed as X-linked ALD and followed up for at least one year were enrolled from 1996 to 2003. Results: 1. Ten had childhood cerebral ALD, who showed first neurologic symptoms at 7.02 years and progressed rapidly: interval between first symptoms and vegetative state was 1.35 years, and interval from initial symptoms to death was 3.35 years. Treatment with Lorenzo's oil did not prevent neurologic progression. Two patients who underwent umbilical cord blood transplantation died. 2. Two had adolescent cerebral ALD. They had first symptoms at 11.5 years, and showed tendency to progress less rapidly than childhood cerebral form patients. 3. One "Addison only" patient who had adrenal insufficiency without nervous system involvement remained asymptomatic during Lorenzo's oil treatment. 4. All cerebral form patients except one showed the lesions in both parieto-ocipital white matter in brain magnetic resonance imaging. Conclusion: The cerebral ALD was the most common form in childhood and was asoociated with a serious prognosis.

  • Purpose : The renal manifestations of tuberous sclerosis complex (TSC) are remarkably diverse, including polycystic kidney disease, simple renal cysts, renal cell carcinomas, and angiomyolipomas. All of these occur in children as well as adults in TSC. Angiomyolipomas, which can cause spontaneous life-threatening hemorrhages, are by far the most prevalent and the greatest source of morbidity. Here, we will address our experience, adding to the literature on pediatric patients with TSC requiring evaluation and treatment for renal manifestations. Methods : A retrospective analysis was made on 19 patients in whom TSC was diagnosed between May 2001 and Oct. 2005 at Severance Hospital. All patients had clinical diagnoses of TSC as defined by the 1998 tuberous sclerosis complex consensus conference. Results : The patients consisted of 13 boys and 6 girls with a mean age of 7.3 years (range 1 to 22). The renal disease associated with TSC included angiomyolipoma in nine patients (47.4 percent), renal simple cyst in one (5.3 percent), hydronephrosis in one (5.3 percent) patient. Eight patients (42.1 percent) presented with normal kidney contours at abdominal ultrasonography. One patient underwent renal replacement therapy due to chronic renal insufficiency after nephrectomy. Hemorrhage from angiomyolipoma was not detected. Conclusion : In our review of 19 cases of TSC, renal manifestations are reported in 57.9 percent of patients. Asymptomatic angiomyolipoma associated with TSC grow gradually, although severe hemorrhages are rare. So patients with TSC should be followed up with serial computerized tomography or abdominal ultrasonography. And also, renal function should be monitored conservatively.

  • A study on the qualify changes of fish meat during drying and storage has been carried out with filefish meat. Filefish meat was dried in a forced air dryer at 40 and $55\%$ for 20 hours with an air velocity of 0.4 m/sec under different conditions of relative air humidities in the range of 10 to $50\%$. The dried fish meat was stored at $30^{\circ}C$ in chambers with constant relative humidities controlled by the use of conditioned air stream passing through the saturated salt solutions. The qualify of filefish meat was evaluated with the brown color densities developed by lipid oxidation and Maillard reaction. Changes of viable cell count during drying and storage were also discussed. The predominant reaction for the brown color developed during the study period was the lipid oxidation. The lipid oxidation rate during drying at constant temperature was appreciably affected by water activities at the drying surfaces of filefish meat during the falling drying rate period. The lipid oxidation rate was the slowest under the condition of the relative air humidity of around $30\%$. In samples stored at water activity of 0.33, the lipid oxidation rate was retarded remarkably in comparison with the samples with lower or higher water activities. The addition of $1\%$ table salt, $1.5\%$ D-sorbitol and $6\%$ sucrose slightly lowered the water activity with the slowest lipid oxidation rate. Such additives resulted the increase of the water soluble brown color densities, which seemed due to the increase of mobility of the water soluble substances by the result of the increase of equilibrium water content. Microflora of the samples immediately after drying consisted of ca. $30\%$ of coccus types, ca. $65\%$ of rod types and ca. $5\%$ of molds and yeasts. During the storage of the samples with a water activity of 0.76, the ratio of the coccus types to the total microflora was increased remarkably while that of the Gram negative non-spore rod types was decreased. The ratios of the Gram positive rod types, molds and yeasts during the storage were nearly constant.

  • Since the world's economic and political structures have changed, the term 'globlization' has shown up as a dominant power and as a necessity for regional and national development. Each nation is responding to the globalization process economically and politically in various ways. In general, however, the economic response to the globalization is economic restructuring from the Fordist industries to 'flexible specialization'. And the political response to the globalization is 'global localization' as a new type of local politics(i.e., local policy activism or growth-enhancing local development policies). The crisis of Fordism shifted the role of local governments towards more involovement with local economic development. Local governments are mobilizing for loca economic development, they are taken into a process of institutional change that tends to redefine their responsibilities inside the state. Local governments thus tend to act as an entrepreneur in order to restructure theiir local economies and to compete with other national and international regions. State restructuring towards enerepreneurialism and efficient regional policy pursuing a pro-growth coalition trategy is chosen as a new mode of regulation for the post-Fordism at the local level. The flexible specialization as the post-Fordist economy and the local government as an entrepreneur are the global choice for globalization and a post-Fordist society. The paper focuses on the regulation theory which comprises the political economic perspective on resturcturing. Economic restructuring and state restructuring will be discussed in detail. And the paper tries to combine the economic globalization and the global localization as economic and political responses to globalization.
