For the first 42 days, we made rats obese by feeding them potato starch instead of corn starch and after that we fed them transformed potato starch by 4 groups for 70 days. The 4 groups are GPS group, SPS group, EZ group and H40 groups and each were fed normal potato, small potato, enzyme treated potato, and acid treated potato starches, respectively. We determined body weight and feeding efficiency, lipid profiles in serum, lipid peroxidation in tissues and redox antioxidant system as GSH and GP-x in vivo. As a result, there was no difference in the increment of body weight in the groups of GPS, EZ and H40. Therefore EZ group showed lower body weight increment than other groups. While GPS group and SPS group did not show significant difference in blood glucose, cholesterol level, LDL-cholesterol and TC, and their measured values were lower than those of EZ and H40 groups. No significant difference was found in HDL-cholesterol level except for GPS group. Furthermore, when calculating atherogenic index (AI) by HDL-cholesterol and TC contents, H40 group showed higher measured value than other groups. When measuring the lipid peroxidation in serum, kidney and liver tissues, the serum lipid peroxidation in H40 group was higher than others. In the tissue of liver and kidney, EZ and H40 groups showed significantly lower contents than others. The content of GSH showed different tendency in each tissue, but the measured value of GP-x activity was lower in SPS group.

This study was carried out to identify basic data for more efficient operation of comprehensive health check-up centers in the national health care system. The researcher reviewed and analyzed the main symptoms of the subjects according to sex, age, occupation and positive rate in the screening tests of a comprehensive health check-up, performed at one comprehensive health check-up center in located in a hospital. The subjects were 512 persons who had a check-up at the comprehensive health check-up, center in K university hospital in Seoul from October 2, 1996 to March 30, 1997. A questionaire developed by the researcher to obtain subject's general characteristics, main symptoms, medical examination, diagnosed disease was used as the tool for the study. The researcher analyzed the data with SPSS PC/sup +/ program. : the distribution of the subject's general characteristics and main symptoms was described with percentages and the difference between main symptoms and screening tests analyzed with X²-test, t-test, ANOVA. The result of this study are as follows : 1. For the distribution of diagnosis in males. liver disease was most frequent and hypertension was second : in females, hypertention and liver disease were not common in that order. 2. The most common complaints were indigestion in the digestive system, sputum in the respiratory system, irregular heart beat in the cardiovascular system, frequent urine in the urinary system vertigo in the hematologic system. 3. The main symptoms according to sex were for females, a statistically siguificant higher rate of complaints in the digestive system, cardiovascular system, urinary system, hematologic system, musculoskeletal, mental & nervous system as compared to males. 4. The main symptoms according to age were that in the the second decade there wara higher rate of complaints in the digestive system, and cardiovascular system than in the older age groups : and in the fifth decade more in the musculoskeletal system. 5. The main symptoms according to occupation were that formers and fishers had a higher rate of complaints in the mental and nervous system as compared to other occupation groups : and office workers, in gynecology. 6. The main symptoms according to diagnosis, were symptoms of the digestive system, frequent in liver disease : symptoms of the cardiovascular system in allergic disease. 7. The screening tests which showed the highest rates were UGI /FGS, PFT : In males a higher rate of abnormality was seen in abdominal ultrasono- graphy and in, females, in mammography. 8. In screening tests according to sex, males showed a higher positive rate for chest X-rays, and LFT, and females, in mammography, pap smear, CBC. 9. In screening tests according to age, higher positive rates of obesity, high blood pressure, chest X-ray, mammography, pap smear, FBS, CBC, urine test were seen in the fifth decade : PFT and abdominal ultrasonography in the third decade. The subjects who wanted comprehensive health check-up were not asymptomatic but had an illness with several symptoms. It is found that the most frequent diagnosed diseases were hypertention and liver disease. So proper observations must be done for them. Comprehensive health check-ups should be changed to a comprehensive examination including treatment beyond examination for those subjects with positive results.

This study is carried out to assess the relative effects of different doses of dietary glucose or fructose on non-alcoholic fatty liver disease (NAFLD) and hepatic metaflammation in a rodent model of type 2 diabetes. KK/HlJ male mice were fed experimental diets as follows: 1) control (CON), 2) moderate glucose (MG, 30% of total calories as glucose), 3) high glucose (HG, 60% of total calories as glucose), 4) moderate fructose (MF, 30% of total calories as fructose), and 5) high fructose (HF, 60% of total calories as fructose) for three weeks. Food intake was not affected by treatments. Compared with HF, HG not only increased serum fasting glucose and area under the curve during oral glucose tolerance test, but also decreased the levels of serum insulin and adiponectin. It indicated that glucose control was complicated via high glucose intake. High fructose treatment led to increased triglyceride in the serum and liver. In comparison to HG, high fructose diet activated NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome consisting of apoptosis-associated speck-like protein containing a CARD (ASC), NLRP3 and caspase 1, which increases interleukin (IL)-$1{\beta}$ maturation and secretion. The activation of NLRP3 inflammasome was accompanied by increased levels of tumor necrosis factor alpha (TNF-${\alpha}$) and IL-6. However, the expression of NLRP3 inflammasome components and pro-inflammatory cytokines did not differ between CON and HG. These data suggested that dietary fructose triggers hepatic metaflammation accompanied by NLRP3 inflammasome activation and has deleterious effects on NAFLD.

The effects of genistein on cell proliferation and adipogenesis were examined in mouse 3T3-L1 preadipocyte cells. Genistein decreased viability of 3T3-L1 pre-adipocytes in a dose-dependent manner. Oil Red O staining of these cells also indicated that adipogenesis was inhibited by 50 ${\mu}M$ genistein treatment. We investigated the molecular mechanisms involved in the decrease in cell viability in genistein-treated 3T3-L1 cells by conducting an oligo DNA microarray analysis. We selected the sirtuin-1 gene, one of the upregulated genes, for further experimentation because sirtuin-1 belongs to the sirtuin family, which is associated with anti-obesity and anti-inflammation activities. We found that four phytochemicals (resveratrol, capsaicin, daidzein, and genistein) could increase sirtuin-1 expression. Genistein was the strongest inducer of sirtuin-1 among the tested phytochemicals. The inhibition of adipogenesis by genistein was recovered by surtuin-1 siRNA transfection. Overall, these results may further our understanding of the molecular mechanisms underlying the inhibition of proliferation and adipogenesis by genistein in mouse 3T3-L1 cells.

The aim of this study was to investigate the latent classes and predictors of chronic diseases such as hypertension, dyslipidemia, arthritis, thyroid disease, depression, atopy, allergy, and diabetes. The subjects of this study were Korean citizens who participated in the Korea National Health and Nutrition Examination Survey in 2014. Stratified cluster sampling method was used with a sample size of 7,550. Latent hierarchy analysis was applied to this data. Four classes were identified. Class 1 consisted of participants with hypertension and diabetes. Class 2 consisted of participants with atopy and allergies. Class 3 consisted of participants with dyslipidemia, arthritis, thyroid disease, and depression. Class 4 consisted of participants without any chronic diseases. In comparing Class 1 to Class 4, age, physical activity, self-management, obesity, and presence of high cholesterol were found to be significant. In comparing Class 2 to Class 4, gender, age, and education level were significant. When Class 3 was compared to Class 4, gender, age, pain and discomfort, as well as high cholesterol were found to be significant. Diabetes and hypertension should be treated as comorbid conditions, applying integrated treatments involving effective drug treatment, diet, and physical activity programs. Atopy was found to be strongly correlated with allergies. Thyroid disease was found to coexist with dyslipidemia and arthritis, along with having a strong correlation to depression. Age-appropriate preventive measures can help reduce the risk of chronic diseases.

Purpose: This study was conducted in order to investigate the effect of Sargassum confusum extracts on the reduction of body fat for eight weeks in overweight women ($BMI{\geq_-}23kg/m^2$). Methods: Subjects were classified by double-blind randomized trial as the control group (C group, n = 14) and the Sargassum confusum extract supplementation group (SC group, n = 16), which consumed 12 tablets per day. Questionnaires related to their health status were assessed twice (week 0 and week 8). Their dietary intake status was evaluated by 24-recall method and body compositions were measured using a bioelectrical impedance analyzer. In addition, we assessed the anti-obesity effect and the occurrence possibility of health risk factors during the supplementation periods by hematological and clinical analysis of blood. Results: Waist circumference and body fat (%) were significantly decreased in the SC group. Serum leptin level was also significantly decreased in the SC group. Defecation frequency was significantly increased in the SC group. The above results indicate that Sargassum confusum extract supplementation improves overweight on visceral fat and blood leptin level by increasing bowel movement. These results imply a decrease of health risk factors in overweight women. Seven subjects withdrew from the study due to adverse events; however, no differences regarding adverse events were observed between the control and treatment group. Conclusion: Therefore, Sargassum confusum extract is a plausible effective agent for body fat reduction in humans.

An 8-year-old spayed female, Yorkshire terrier dog was presented with a urinary incontinence. Unaware urine dribbling during sleeping was observed eight months after spaying. Polyuria and polydipsia were also reported. Physical examination revealed obesity and hypertension. Characteristic laboratory findings in this dog were polycythemia, hyperlipidemia and elevated hepatic enzyme. Other causes of the urinary incontinence were ruled out through further diagnostic tests and spay-related urethral sphincter mechanism incompetence (USMI) was made as a presumptive diagnosis. In addition, the dog was also diagnosed with pituitary-dependent hyperadrenocorticism. Both conditions can cause urinary incontinence in dogs; therefore, definite diagnosis was made through a therapeutic approach. The synthetic estrogen, diethylstilbesterol, was initially administered and successfully managed the urinary incontinence in this dog. To the best of the author's knowledge, this is the first case report describing the clinical and laboratory features of spay-related USMI concurrent with hyperadrenocorticism and treatment outcomes in our country.

Objectives: The purpose of this study was to evaluate the relationship of nonalcoholic fatty liver and cardiovascular risk factors. Methods: This study was conducted to investigate the association of nonalcoholic fatty liver and cardiovascular risk factors for adult men (n=2976) and women (n=2442) who were over 19 years old, after excluding the HBsAg(+) or anti-HCV(+) patients and the men and women with increased alcohol intake (men: 40g/week, women: 20g/week). Results: Compared with the normal liver subjects, the nonalcoholic fatty liver subjects showed a significantly increased frequency of abnormal systolic blood pressure (${geq}120mmHg$), fasting blood sugar (${\geq}100mg/dL$), total cholesterol ($({\geq}200 mg/dL$), triglyceride ($({\geq}150mg/dL$), high density lipoprotein cholesterol (<40 mg/dL), low density lipoprotein cholesterol ($({\geq}130g\; m/dL$) and abdominal obesity in men, and all these measures were significantly increased in the women except for abnormal HDL cholesterol. After adjusting for the body mass index, age, smoking, exercise and a nonalcoholic liver, the odds ratios of an abnormal waist hip ratio were 1.35(95% Confidence Interval=1.05-4.72) in the mild fatty liver, 1.61 (1.19-2.18) in the moderate fatty liver, 2.77(1.57-4.92) in the severe fatty liver compared with a normal liver. The adjusted odds ratios for abnormal fasting blood sugar were 1.26(1.03-1.53) in the mild fatty liver, 1.62(1.27-2.06) in the moderate fatty Iiver and 1.77(1.12-2.78) in the severe fatty liver. The adjusted odds ratios for abnormal triglyceride were 1.38(1.11-1.72) in the mild fatty liver, 1.73(0.33-2.24) in the moderate fatty liver and 1.91 (1.17-3.10) in the severe fatty liver of men. Adjusted odds ratios for abnormal triglyceride were 1.50(1.04-2.15) in mild, 1.71(1.07-2.68) in moderate, 1.81(0.69-4.38) in severe fatty liver of women. Conclusions: The nonalcoholic fatty liver subjects had more cardiovascular risk factors compared with the normal liver subjects. Thus, prevention and treatment of the nonalcoholic fatty liver is necessary by lifestyle modifications such as restriction of alcohol intake, no smoking, exercise and adequate eating habits.
