Delirium is a syndrome characterized by impairement of consciousness, disorientation, disturbance of sleep-wake cycle, memory impairement, disturbance of perception. It is induced by many causes, which are CNS diseases(head trauma, vascular disease, brain tumor, etc), medical diseases(metabolic disorder, endocrine disturbance, cardiovascular disease) and drugs(anticholinergics, anticonvulsant, antipsychotics, cimetidine etc). Transdermal scopolamine which is usually used to prevent motion sickness has anticholinergic property, and so it can induce delirium. The authors report two cases of delirium induced by transdermal scopolamine. The cases shared common characteristics which were as follows : 1. All of two patients were elderly women. 2. Delirium symptom was abruptly occurred during trip after attaching scopolamine patches. 3. Delirium symptom was rapidly improved within 2-3 days. It is important to educate for both users and managers about directions for transdermal scopolamine patch usage to prevent delirium. And careful history taking is needed to diagnose delirium induced by transdermal scopolamine accurately.

Over the a few decades, the incidences of obesity and associated metabolic syndrome diseases have been increased dramatically and resulted in a global health crisis. Recent findings suggest endocrine disrupting chemicals (EDCs) as an obesogen, because they disrupt normal development and homeostatic controls over adipogenesis and energy balance in obesity. Furthermore, risk of cardiovascular disease and mortality is elevated among those who were obese during childhood. Thus, we focused on etiology of obesity in children and performed biological monitoring of bisphenol A (BPA), which is a broadly exposed EDC in environment. Study subjects were age and sex-matched obese and normal children in Seoul (N=52; age, $8.67{\pm}1.46$ years). Exposure levels of BPA were analyzed with HPLC/FLD as a conjugated form in urine. As results, ranges of urinary BPA were 0~54.38 ${\mu}g/g$ creatinine (median, 4.57 ${\mu}g/g$ creatinine). Levels of urinary BPA were 1.7 fold higher in the obese children than those in the controls (medians of obese and control children, 7.31 and 4.25 ${\mu}g/g$ creatinine, respectively, p=0.22). In the near future, enlarge scaled studies should be performed to confirm the risk of BPA for obesity.

Objective: This study was performed to investigate the prevalence of impaired fasting glucose (IFG) and its related characteristics among healthy adults in some Korean rural areas. Methods: We conducted a cross-sectional study using the data from 1352 adults who were over the age 40 and under the age 70 and who were free of diabetes mellitus (DM), cardiovascular diseases and other diseases and who participated in a survey conducted as part of the Korean Rural Genomic Cohort Study. IFG was defined as a serum fasting glucose level between 100 and 125 mg/dL. Results: The prevalence of IFG was 20.4% in men, 15.5% in women and 12.7% overall. Multivariate logistic regression analysis demonstrated that the independent risk factors for IFG were male gender, having a family history of DM, the quartiles of gamma glutamyltransferase and high sensitive C-reactive protein and the waist circumference. The homeostatis model assessment for insulin resistance was very strongly associated with IFG. The prevalence of metabolic syndrome (MS) and MS components was higher in the subjects with IFG then in those with normal fasting glucose (NFG). Conclusions: The result of study could supply evidence to find the high risk population and to determine a strategy for treating IFG. Further research is needed to explain the causal relationship and mechanisms of IFG.

This review discusses the characteristics of major lignans and related studies and provides a basis for future studies. Lignans are present in various food products consumed daily, such as flaxseed and other seeds, vegetables, fruits, and beverages including coffee, tea, and wine. Lignans are natural phytoestrogens with a structure similar to that of secoisolariciresinol (Seco), mataireinol (Mat), pinoresinol (Pin), medioresinol (Med), lariciresinol (Lari), and syringaresinol, which is then converted to enterodiol (END) and enterolactone (ENL), which are mammalian lignans and the primary biologically active enterolignans, by the intestinal microflora. The associations between lignans and a decreased risk of cardiovascular disease are promising; however, they are not yet well-established, probably owing to low lignan intake in habitual Western diets. Nonetheless, these associations were more prominent at the higher doses in interventional studies. Many studies on humans and animals have reported the benefits of lignan consumption in protecting against CVD and metabolic syndrome by reducing lipid and glucose concentrations. END and ENL reportedly exert protective effects including phytoestrogenic, antioxidant, anti-inflammatory, and anticancer effects through various mechanisms. Moreover, lignans reportedly exert beneficial effects in breast, colon, and prostate cancer and osteoporosis have reported that. However, future studies are required to confirm the association between lignan and disease.

Purpose: The purpose of this study was to describe the intervention model development of health promotion for women workers working in the traditional marketplace, using community capacity building framework. Methods: Need assessment of the target population, work-related environment investigation, social network group building, and setting health management in the marketplace were performed. Then the interventions including cardiovascular health, musculoskeletal health, and psychological health were conducted. The results were evaluated using NCEP-ATP III(National Cholesterol Education Program's Adult Treatment Panel III), OWAS, and CES-D. Results: It was found that the intervention program for the vulnerable group in marketplace was appropriate, promoting the improvement of metabolic syndrome and the reduction of pain complaints. Therefore, the intervention framework for health promotion of women workers in the marketplace was developed. Work-related environment assessment also was included in the framework development. Several community capacity building strategies, including developing community resources and promoting partnership, making small social network group, and promoting program participation. Conclusion: It is suggested that occupational health nurses and professionals consider the appropriateness of intervention framework development after identifying the needs of women workers' work-related environmental problems.

Objectives: Metabolic syndrome has received attention as a risk factor for cardiovascular disease, with particular importance attached to visceral fat accumulation, which is associated with lifestyle-related diseases and is strongly correlated with waist circumference. In this study, our aim is to propose waist circumference cut-off values that can be used as a marker for fatty liver based on a sample of workers receiving health checkups in Japan. Methods: This study was conducted in a total of 21,866 workers who underwent periodic health checkups between January 2007 and December 2007. The mean age of the subjects was 47.4 years for men (standard deviation [SD]: 8.0) and 44.7 years for women (SD: 6.9). Evaluation included abdominal ultrasound and measurement of waist circumference, body mass index, fasting blood glucose, triglycerides, high-density lipoprotein cholesterol, and blood pressure. Results: Based on receiver operating characteristic curve analysis, the optimal waist circumference cut-off values were shown as 85.0 cm (sensitivity 0.72, specificity 0.69) for men and 80.0 cm (sensitivity 0.75, specificity 0.78) for women. Conclusion: Abdominal ultrasound is the most efficient means of diagnosing fatty liver, but this examination seldom occurs because the test is not routinely performed at workers' health checkups. In people found to have a high risk of fatty liver, recommendations can be made for abdominal ultrasound based on the waist circumference cut-off values obtained in this study. That is, waist circumference can be used in high risk individuals as an effective marker for early detection of fatty liver.

Elevated serum uric acid levels are associated with a variety of adverse health outcomes, including gout, hypertension, diabetes mellitus, metabolic syndrome, and cardiovascular diseases. Several genome-wide association studies on uric acid levels have implicated the ATP-binding cassette, subfamily G, member 2 (ABCG2) gene as being possibly causal. We investigated an association between the single-nucleotide polymorphism (SNP) rs2725220 in the ABCG2 gene and uric acid levels in the Korean population. A total of 991 subjects in Seoul City were used for a replication study with ABCG2 SNP rs2725220. The rs2725220 SNP in the ABCG2 gene was associated with mean uric acid levels (effect per allele 0.25 mg/dL, p < 0.0001). Subjects with the GC/CC genotype had a 1.78-fold (range, 1.22- to 2.62-fold) higher risk of having abnormal uric acid levels (${\geq}7.0mg/dL$) than subjects with the GG genotype. When analyzed by gender, the association with ABCG2 was stronger in men than in women. The association with ABCG2 was much stronger in male subjects with body mass index (BMI) ${\geq}26.4$ (odds ratio, 5.09; 95% confidence interval, 2.41 to 10.8) than in male subjects with BMI < 26.4. This study clearly demonstrates that genetic variations in ABCG2 influence uric acid levels in Korean adults.

Objectives The objective of this study is to develop a taeeumin animal-experimental model induced lung fibrosis with Bleomycin and evaluate the effect on obesity in this animal-experimental model.Methods The subjects were divided into 3 groups : normal group, high fat diet(HFD) control group, and HFD group administered with bleomycin(n=10 per group). To develop taeeumin animal-experimental model with reduced respiratory metabolism, 8-week-old C57BL/6 mice were administered with 0.03ml solution of bleomycin 1U/ml dissolved in distilled water, intratracheal(IT), once. Then, the HFD control group and the experimental group were fed with high fat diet for 6 weeks. Airway hyperresponsiveness(AHR) to methacholine was measured at the 1st and 3rd week after bleomycin was administered. Food intake and body weight were measured at regular time weekly. After the final experiment, blood was gathered by cardiac puncture for bloodchemical examination and organs(liver, fatty tissue) were remoed, weighted, and mRNA was analyzed.Results and Conclusions Through the experiment, it was found that Bleomycin induced Taeeumin animal-experimental models have leptin resistace. In the experimental group administered with Bleomycin, fatty acid synthesizing gene expression increased and energy metabolizing gene expression decreased. As mRNA expression of adiponectin decreased, it was found that Taeeuim animal-experimental model is susceptible to metabolic syndrome and cardiovascular diseases.

Abdominal obesity is an important factor of metabolic syndrome and is known as an independent risk factor of cardiovascular disease. The purpose of this study was to examine the fatty acid intake pattern as well as the association between fatty acid intake and abdominal obesity and hyperglycemia in Korean adults. This study was based on data from the Korea National Health and Nutrition Examination Surveys (KNHANES) I, II, III, and IV. After excluding subjects who had missing data for dietary intakes, anthropometric measurments, and laboratory tests, a total of 12,320 subjects aged 20~64y (5,266 men and 7,054 women) were included in the study. Trends in individual consumption of dietary fatty acids by year were analyzed by One-way ANOVA test, and the association between fatty acid intake and abdominal obesity and hyperglycemia was analyzed by logistic regression analysis after adjusting for age, energy intake, marital status, job, education level, alcohol intake, and smoking status. In men, intakes of TFA, SFA, MUFA, FUFA, and n-6 PUFA significantly increased with year. On the other hand, intakes of TFA, SFA and FUFA significantly increased with year in women. Logistic regression analysis showed that the risk of abdominal obesity was significantly associated with intakes of PUFA, LNA and n-3 PUFA in women. However, there was no association with any fatty acid intakes in men. The risk of hyperglycemia was significantly and positively associated with intakes of TFA, SFA, PUFA, and LNA in men, but, there was no significant association with any fatty acid intakes in women. These results show that abdominal obesity and hyperglycemia are significantly associated with individual intake of fatty acids, suggesting that fatty acid type may be associated with risk of abdominal obesity and hyperglycemia. Futher, the macronutrients of measl must be properly balanced.

Objectives: Normal weight obesity (NWO) is defined as excessive body fat in the context of a normal body mass index (BMI). This condition carries a greater risk of developing noncommunicable chronic disease and has been associated with early inflammation. This study was conducted to compare the anthropometric measurements, eating behaviors, and blood clinical indices among four groups: underweight, normal, normal weight obesity and obesity. Methods: The subjects included 215 female college students. A questionnaire was administered regarding general characteristics, dietary behaviors, food consumption frequency. Anthropometric measurements and blood clinical indices were also investigated. Results: The average BMI, body fat percentage, waist circumference, fat-free mass, and muscle mass were highest in the obesity group (p<0.05). Most subjects had tried to lose weight and perceived that their health was worse than before they became college students. The ratio of students in the NWO group who thought their health was very poor was significantly higher than in the other three groups (p<0.05). The obesity and NWO groups seemed to eat more and their eating speed was significantly faster than the other groups (p<0.001). The consumption frequency of caffeinated beverages was significantly higher in the NWO group than in the other three groups (p<0.01). WBC was significantly higher in the obesity group (p<0.05). Serum levels of TG and total cholesterol were also significantly higher in the obesity group (p<0.05). Serum GPT was significantly higher in the obesity group (p<0.05) while BUN level was highest in the NWO group (p<0.05). Conclusions: The obesity group showed the most health problems while the NWO group seemed relatively healthy. However, NWO can lead to problems such as metabolic syndrome and cardiovascular disease in later life if poor dietary habits are maintained. Therefore, education in appropriate eating habits is needed for these subjects.
