Purpose: Obesity is defined as the abnormal or excessive accumulation of fat over acceptable limits. Leptin is a metabolic hormone present in the circulation in amounts proportional to fat mass. Leptin reduces food intake and increases energy expenditure, thus regulating body weight and homeostasis. Various polymorphisms are present in the leptin gene and its receptor. These polymorphisms may be associated with obesity. This study aimed to show the association of leptin (+19) AG, leptin (2548) GA, and Gln223Arg leptin receptor polymorphisms with obesity and metabolic syndrome in Turkish children aged 6-17 years, and to conduct further investigations regarding the genetic etiology of obesity. Methods: A total of 174 patients diagnosed with obesity and 150 healthy children who were treated at Tokat Gaziosmanpasa Medical School Hospital between September 2014 and March 2015 were included in this study. The ages of the children were between 6 and 17 years, and anthropometric and laboratory results were recorded. Genotyping of leptin (+19) AG, leptin (2548) GA, and leptin receptor Gln223Arg polymorphisms was performed by polymerase chain reaction. Results: An association between leptin receptor Gln223Arg gene polymorphism and obesity was detected. Conclusion: Further studies are needed to determine the role of genetic etiologies and to indicate the role of leptin signal transmission impairment in the pathogenesis of obesity. We hope that gene therapy can soon provide a solution for obesity.

Objectives : The purpose of this study was to estimate the prevalence of metabolic syndrome, as defined by the ATP III report, in some Korean adults and use the Asian-Pacific proposed waist circumference to investigate waist circumference in some Korean adults using ROC curves. Methods : Study subjects were seventy-five thousands and ninety one persons(47,979 men and 27,111 women) who were selected among the patients who visited hospital for health evaluation from January 2000 to December 2001. All subjects were measured by height, weight, waist and hip circumferences, blood pressure and blood chemistry(lipid profile). Results : The mean age was $41.6{\pm}8.5$ years in men, $41.1{\pm}10.4$ years in women(p<0.05). Body mass index was in the normal range in 35.3% of men, and 55.9% of women. In both men and women, blood pressure, blood sugar, total cholesterol and triglyceride were positively correlated with BMI. waist circumference, and Broca's index(p<0.01). However HDL. choloesterol was correlated negatively (p< 0.01). Using ROC curve, the calculated waist circumferences were 84 cm in men(sensitivity 61.4% and specificity 64.1%) and 74 cm in women(sensitivity 65.0% and specificity 73.2%). The age adjusted prevalences of the metabolic syndrome as defined by NCEP ATP III were different for men(6.4%) and women(14.6%). The prevalence increased from 1.2% among participants aged 20 through 29years to 15.0% among participants aged over 60years in men(p<0.05) and from 1.6% to 27.4% respectively, in women. The age adjusted prevalences, as defined by using the waist circumference that was recommended by WHO's regional office for the western Pacific, were 10.6% in men and 18.5% in women. The age adjusted prevalences, as defined by using the waist circumference that was calculated by the ROC curves, were 17.1% in men and 22.4% in women. And All prevalences were increased following increased BMI and Broca's index. Conculsions : The prevalence of metabolic syndrome in some Korean adults was lower than that in western adults. Nevertheless because waist circumference was differed among race and region, application of the same criteria was not proper. Morcover, a higher awareness was required in women, because the prevalence of metabolic syndrome was rapidly increased with increment of age.

Gracilaria Verrucosa (GV), a seaweed used in traditional Korean medicine, was studied for its effects on MI-induced heart failure in rats. MI is caused by a blocked coronary artery, leading to severe cardiac dysfunction. The study used a rat model to assess cardiac changes over time and evaluate the impact of GV on heart failure. Ischemia was induced through LAD ligation surgery, and the extent of ischemic area was measured as a prognostic factor. GV extract administration significantly improved cardiac morphology and reduced cardiac weight compared to the MI group. GV treatment also improved cardiac function, as evidenced by positive effects on chamber dilation during MI-induced heart failure. Parameters such as ejection fraction (EF) and fractional shortening (FS) were measured. The MI group showed decreased EF and FS compared to the sham group, while these parameters improved in the GV group. GV treatment also reduced levels of LDH, CPK, and CK-MB in the serum, indicating reduced myocardial damage. Histological analysis revealed that GV treatment attenuated cardiac hypertrophy and fibrosis, with reduced collagen deposition in the myocardium. Immunohistochemistry analysis showed suppressed expression of TGF-β1 and collagen 1, involved in fibrosis. In conclusion, GV showed potential in improving cardiac function in a rat model of MI-induced heart failure. It alleviated myocardial damage, attenuated cardiac hypertrophy and fibrosis, and suppressed fibrotic markers. Further studies are needed to explore its clinical efficacy and underlying mechanisms in cardiac diseases beyond animal models.

Hantaan (HTNV) and Puumala (PUUV) viruses cause hemorrhagic fever with renal syndrome in human. In the present study, the repeated dose toxicity of the HTNV-PUUV combination vaccine was evaluated in Sprague-Dawley rats. Animals were injected subcutaneously for 28 days with dosages of 0, 0.017, 0.17 and 1.7 dose/kg body weight per day, respectively. No any significant changes of body weight, food and water consumptions were shown. There were no death and clinical findings during the experimental period. In both male and female rats, there were not significant changes in hematological and serum biochemical analysis, urinalysis, and ophthalmoscopic and histopathological examination. These results indicate that the HTNV-PUUV combination vaccine may have no toxic effects and no observed adverse effect level (NOAEL) may be over 1.7 dose/kg/day at subcutaneous route in rats.

Over the past few decades, there has been a notable increase in the incidence of pediatric obesity, which is a significant public health concern. Children who are obese have a greater risk of type 2 diabetes, hypertension, dyslipidemia, polycystic ovary syndrome, obstructive sleep apnea, and adult obesity. Lifestyle modification therapy is typically the initial approach to treat pediatric obesity. For patients who do not achieve success with lifestyle modification therapy alone, pharmacotherapy is the next logical treatment option. When selecting an anti-obesity medication (AOM), it is essential to first ascertain the medical background of the patient, including current medications and obesity-associated comorbidities. Evaluation of obesity phenotypes in patients may also be beneficial. AOMs for pediatric obesity include metformin, orlistat, glucagon-like peptide 1 agonists, phentermine, and the phentermine/topiramate combination. Sufficient lifestyle modification therapy should be administered before considering pharmacotherapy and continued after the initiation of AOM. To ensure healthy development, monitoring growth and puberty development during anti-obesity treatments is essential.

BACKGROUND/OBJECTIVES: This study was conducted to compare the overall changes in dietary intake and metabolic syndrome risk parameters in Vietnamese marriage-based female immigrants over time. SUBJECTS/METHODS: The subjects of this study were 581 Vietnamese marriage-based female immigrants, who were recruited from local clinical centers in Korea. Baseline data were collected from 2006-2011 and the follow-up data were collected from 2012-2014. Dietary food intake was assessed by a 1-day 24-hour recall method. RESULTS: Compared to the baseline, the mean body weight, body mass index, waist circumference, high density lipoprotein (HDL)-cholesterol, systolic blood pressure and diastolic blood pressure increased while the fasting blood sugar, triglycerides and low density lipoprotein-cholesterol decreased at follow-up. The total consumption of foods such as vegetables/fruits/seaweeds/mushrooms, oil and fat, and eggs decreased during the follow-up period, whereas the consumption of sugars, beverages and meats increased. Partial correlation between the rate of change [(Follow-up - Baseline) / Baseline ${\times}100$] in metabolic syndrome risk parameters and food intake after controlling for confounding factors showed that the waist circumference was positively correlated with either the total plant food intake (r = 0.1042, P = 0.0129) or the total food intake (r = 0.0880, P = 0.0359). The plasma levels of total cholesterol (r = -0.1918, P = 0.0289) and HDL-cholesterol (r = -0.1424, P = 0.0007) were negatively correlated with the percentage of total intake from plant food, and HDL-cholesterol levels were positively correlated with the intake of total animal food (r = 0.0980, P = 0.0217). The serum C-reactive protein levels were positively correlated with the total intake of animal food (r = 0.2374, P < 0.0001) or the percentage of total intake from animal food (r = 0.1346, P = 0.0016). CONCLUSIONS: These results suggest that the change rate of dietary intake such as total plant food or animal food is associated with the change rates of metabolic syndrome risk parameters.

본 연구는 농촌지역 주민들의 대사증후군 예방을 위한 영양 사업에 기초 자료를 제공하고자 안동시 읍면 지역 농촌의 45세 이상 주민을 대상으로 신체특성 및 건강관련 생활습관이 대사증후군 발생에 미치는 영향을 다항로지스틱회귀모델을 사용하여 분석하였다. 분석 대상자 1,431명 중 대사증후군 유병율은 38.2%(남자 23.5%, 여자 46.9%)로 남자에 비해 여자의 유병율이 유의적으로 높게 나타났는데 이는 폐경기 이후 여성에서의 대사증후군 비율이 증가하는 것과 관계가 있다고 할 수 있다. 대사증후군 위험인자 중 유병율이 가장 높은 요인은 혈압이었고, 다음은 낮은 HDL-콜레스테롤, 복부비만, 높은 혈당, 높은 혈중 중성지방 순으로 나타나 이 지역 주민의 대사증후군 유병율을 낮추기 위해서는 혈압을 내리고 HDL-콜레스테롤을 높이며 복부비만을 감소시킬 수 있는 방안을 모색할 필요가 있다고 생각된다. 한편, 대사증후군 위험인자를 한 개 이상 가진 사람은 94.7%, 두 개이상은 68.9%로 나타났다. 대사증후군 발생위험요인과 위험도를 분석한 결과 대사증후군 발생 위험도는 남자에 비해 여자가 2.953배 높았다. 체지방율의 경우 정상체중에 비해 비만에서 남녀 각각 5.786배와 13.498배 대사증후군의 위험이 높았으며, 체질량지수로는 정상체중에 비해 비만에서 남녀 각각 3.782배, 13.301배, 고도비만에서는 21.516배, 21.482배 대사증후군의 위험도가 높았다. 건강관련 습관인 흡연, 음주, 운동, 농사활동 시간은 대사증후군 발생위험요인으로 나타나지 않았다. 이상의 결과로부터, 안동 농촌지역 주민들의 대사증후군 유병율을 낮추기 위해서는 혈압과 폐경 여성들의 복부비만에 대한 철저한 관리가 필요한 것으로 생각된다. 아울러 건강관련 습관인 흡연, 음주, 운동 등이 대사증후군 발생에 미치는 영향에 대해서는 더 많은 연구가 필요하다고 사료된다
