Obesity has increased dramatically increased in recent days. It has resulted in obesity-associated diseases and metabolic syndromes including hyperlipidemia, diabetes and cardiovascular diseases. Our study was investigated to determine the antiobese effects of mixed 2 medicinal herbs (AR+AC) in rats fed high-fat diet with an abundance of carbohydrates. Two groups of male Sprague-Dawley rats were fed different diets during 8 weeks: normal diet containing 5% corn oil (w/w), high-fat diet containing 10% (w/w) lard plus 5% (w/w) corn oil (HF). And High-fat diet group was treated with saline or 100 mg/kg ARAC or 300 mg/kg ARAC (PO). Antiobese effect was evaluated by measuring the changes of body weight, adipose tissues weight. Also we examined levels of leptin, adiponectin and lipid profiles in serum. Finally we compared morphological change in adipocytes and hepatocytes between HF and ARAC group. Mixed combination of 2 medicinal herbs, but not alone, caused significant decrease in body weight, organ weight (liver, epididymal fat, and BAT) compared with control HF group. The ARAC group had markedly lower serum levels of adiponectin when compared with HF group. Also the epididymal white adipocyte size of ARAC group were diminished comparing to the HF group. These results suggest that the possibility of ARAC combination, as an antiobese formula, by suppression of body weight gain and increased lipid profiles.

The aim of this study was to investigate the effect of Taeeumjowuitanggagam-bang (TJV) on the mRNA expression of Sterol regulatory element binding proteins (SREBPs), Tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and Interlukin-6 (IL-6) that are considered to play an important role in lipid and glucose metabolism. For diet-induced obese studies, we split mice into 2 groups. The low fat diet group (LFD, n=8) were supplied with general diet for 10 weeks and the high fat diet group (HFD, n=18) were supplied with 60 kcal% fat diet for 10 weeks. And then The HFD group, the diet-induced obese group, were divided into 3 groups ; a group supplied with normal saline, a group treated with TJV 200 mg/kg and a group treated with TJV 500 mg/kg. They were treated orally with TJV and measured their body weight every day during 10 weeks. After that, we measured mRNA expressions of TNF-$\alpha$, IL-6 and SREBP-1c in liver, and blood concentrations of glucose, total cholesterol and triglyceride too. The results are as follows. The TJV reduced glucose and total cholesterol of blood concentration. The TJV reduced the mRNA expressions of TNF-$\alpha$ and SREBPs in liver. However, We couldn't find the TJV effects on the mRNA expression of IL-6, triglyceride blood concentration, and body weight among groups. The TJV stained liver tissue less red than control group. These results suggest that TJV may be effective for regulation of lipid and glucose metabolism in liver.

A national animal health monitoring system(NAHMS) in Gyeongnam area was started from 1997 to develop statistically valid data for use in estimating disease frequencies in dairy cattle, and the associated costs. The objectives of this study were to : (1) discribe what was done to implement and maintain the system in Gyeongnam ; (2) present selected disease frequencies ; (3) discuss the epidemiological consideration of what was done and implications for the results obtained. Veterinary Medical Officers(VMOs-professors and graduate students from Gyeongsang National University, Faculty of Gyeongnam Livestock Promotion Institute, and Clinic veterinarians) served as data collectors. After training on current disease and management problems of dairy cattle, interview techniques, sampling methods, and data collection instruments, the VMOs participated in selection of the sample herds and data gathering. Forty of 167 dairy herds were selected randomly and the VMOs visited farms once a month for 12 months to collect data about management, disease, inventory, production, preventive treatment, financial and any other relevant data. Strict data quality control devices were used. Specific feed-back was developed for the producers and data collectors. Of the three age groups studied, cows had the greatest number of disease problems. The six disorders found most frequently were (from the highest to the lowest) breeding problems, clinical mastitis, birth problems, gastrointestinal problems. metabolic problems, and lameness. In young stock, respiratory, multiple system, breeding problems, and gastrointestinal problems were pre dominant, whereas in calves, gastrointestinal, respiratory, and integumental problems were major.

Osteoporosis is a age-related metabolic disorder. Currently there is no cure, but there are measures that can prevent or deter the development of osteoporosis. Futhermore lifestyle among risk factors of osteoporosis may be modifiable. Osteoporotic preventive health promotion behavior may be more effective at early adult when they make formation of peak bone mass. The purpose of this study is to identify the demographic variables, life-style and level of concern about osteohealth-related factors according to the health promotion behavior among university female students. The result are following: 1. The highest level of concern about osteoporosis-related factor is sufficient sleeping. 2. The highest level of dietary about osteoporosis-related factors are vegetable and fruit. 3. Level of concern about osteoporosis-related factors according to demographic variables are not significantly different, but dietary were significantly different in age, height and income. 4. Level of concern about osteoporosis-related factors according to lifestyle are significantly different in weekly hour of exercise and weight control, and dietary are significantly different in milk intake at elementary school and present. 5. Level of concern about osteoporosis-related factors have correlated positively with dietary. University and College female students who participated in this study have concerned middle at calcium intake and exercise, but two variables are significantly different in lifestyle and dietary. Because of two variables are modifiable, it should be regarded importantly in nursing domain. We suppose that preventive education of osteoporosis is necessary to reach peak bone mass and to maintain bone mass consistently among the University and College female students.

The effect of the traditional herbal medicine Yukmijihwangtang-Jahage(YJ) on the improvement of insulin resistance and lipid profile was studied using a model for non-insulin dependent diabetes mellitus, lean (Fa/-) and obese (fa/fa) Zucker rats. Yukmijihwangtang-Jahage feeding for 4 weeks resulted in a significant decrease in the concentration of plasma triglyceride in both lean and obese Zucker rats. Furthermore, Yukmijihwangtang-Jahage markedly decreased both plasma cholesterol and fasting plasma insulin, and significantly decreased the postprandial glucose level at 30 min during oral glucose tolerance test in obese Zucker rats. Although there was no statistical significance, the crude glucose transporter 4 protein level of Yukmijihwangtang-Jahage dieted obese rats tended to increase when compared to that of obese control rats. Therefore, the present results suggested that Yukmijihwangtang-Jahage may be useful in prevention and improvement of metabolic disorders characterized by hyperinsulinemia states such as non-insulin dependent diabetes mellitus, syndrome X and coronary artery disease.

Objectives : The purpose of this study was to find the protective effects of garlic on the halogenated hydrocarbon induced hepatotoxicities, and the possible protection mechanisms involved. Methods : Male Sprague-Dawley rats received garlic (0.5%) or regular diet, for 4 weeks. This was followed by a single dose of corn oil (the controls), carbon tetrachloride (400mg/kg body weight) and trichloroethylene (2,000mg/kg body weight) being administered to each diet group. Blood samples were collected 24 hours fellowing the administration, and the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALD activities measured. The liver samples were studied for their cytochrome P450 and CYP2E1 contents, lipid peroxidation and histopathology. Results : rho results for the group receiving the 9.5% garlic diet showed a slight decrease of CYP2E1 expression compared with the regular diet group. Carbon tetrachloride was significantly decreased the CYP2E1 contents in both the regular and garlic diet groups, but the trichloroethylene remained unchanged. Garlic did not decrease the lipid peroxidation of the liver in the control group, but attenuated the increase of lipid peroxidation caused by carbon tetrachloride. Garlic attenuated the increase of both the serum AST and ALT activities caused by carbon tetrachloride. The histopathelogical observations also showed that garlic attenuated centrilobular necrosis and vacuolar degenerative changes significantly in the carbon tetrachloride treated group. Conclusions : The results indicate that garlic attenuates the carbon tetrachloride-induced hepatotoxicity, through the prevention of the metabolic activation and lipid peroxidation.

Obesity occur from the imbalance between energy intake and energy expenditure. Obesity is a complex chronic disease that is suggested to cause other metabolic disorders such as type 2 diabetes, hyperlipidemia, hypertension, and arteriosclerosis. In this study, our purpose is to investigate the anti-hyperglycemic and anti-obesitic effects of Maydis stigma water extract in 3T3-L1 adipocytes and db/db mice. Maydis stigma water extract at dose of 100 and 500 ${\mu}g/ml$ slowly inhibited cell viability as compared to that of control in mature adipocytes. Also, the additions of 50 and 250 ${\mu}g/ml$ of Maydis stigma water extract significantly inhibited the lipid accumulations and CCAAT/enhancer-binding protein(C/EBP) ${\alpha}$ and peroxisome proliferator-activated receptor(PPAR) ${\gamma}$ expressions with dose-dependent manner in 3T3-L1 adipocytes. Maydis stigma water extract at 250, 500, and 1000 ${\mu}g/ml$ only showed the increasing pattern on lipolysis activity. The oral treatment of Maydis stigma water extract (100 or 400 mg/kg body weight) in db/db mice only showed tendency to decrease body weight, food efficiency ratio (FER), HbA1c, blood glucose, total cholesterol, triglyceride, and the adipocyte size of in db/db mice. However, Maydis stigma water extract increased the insulin level in a dose dependent manner. Thus these results indicate that Maydis stigma water extracxt inhibits adipogenesis through regulation of C/EBP${\alpha}$ and PPAR${\gamma}$ expressions in 3T3-L1 adipocytes and shows anti-hyperglycemic effect through increase of insulin secretion in db/db mice.

Green shoot cuttings of 10 different grapevine species were inoculated with Agrobacterium vitis to find disease-related metabolites in the grapevine. Crown galls formed 60 days after inoculation varied in gall severity (GS) evaluated by gall incidence (GI) and gall diameter (GD), which were classified into three response types as RR (low GI and small GD), SR (high GI and small GD), and SS (high GI and large GD), corresponding to resistant, moderately resistant, and susceptible responses, respectively. In this, 4, 4, and 2 Vitis species were classified into RR, SR, and SS, respectively. Gas chromatography mass spectrometry (GC-MS) analysis of the grapevine stem metabolites with A. vitis infection showed 134 metabolites in various compound classes critically occurred, which were differentially clustered with the response types by the principal component analysis. Multivariate analysis of the metabolite profile revealed that 11 metabolites increased significantly in relation to the response types, mostly at post-inoculation stages, more prevalently (8 metabolites) at two days after inoculation than other stages, and more related to SS (7 metabolites) than RR (3 metabolites) or SR (one metabolite). This suggests most of the disease-related metabolites may be rarely pre-existing but mostly induced by pathogen infection largely for facilitating gall development except stilbene compound resveratrol, a phytoalexin that may be involved in the resistance response. All of these aspects may be used for the selection of resistant grapevine cultivars and their rootstocks for the control of the crown gall disease of the grapevine.

Extract from Gryllus bimaculatus crickets inhibits oxidation at the DNA level, with reduced production of 8-hydroxy-2'-deoxyguanosine (8-OHdG). Microarray analyses were performed with a rat 28K cDNA clone set array to identify the gene expression profiles of aged (10 months old) Wistar Kyoto rats treated for one month with 100 mg/kg G. bimaculatus ethanol extract to assess the effects. The extract produced a meaningful anti-edema effect, evident by the inhibition of creatinine phosphokinase activity. The weights of abdominal and ovarian adipose tissues were reduced and the proportion of unsaturated fatty acids in adipose tissues was increased in an extract dose-dependent manner. Compared with untreated control rats, rats treated with the extract displayed the upregulation of 1053 genes including Fas (tumor necrosis factor receptor superfamily, member 6), Amigo3 (adhesion molecule with an immunoglobulin-like domain), Reticulon 4, 3-hydroxy-3-methylglutaryl-coenzyme (Hmgcr; a reductase), related anti-fatigue (enzyme metabolism), and Rtn antioxidant, and the downregulation of 73 genes including Ugt2b (UDP glycosyltransferase 2 family), Early growth response 1, and Glycoprotein m6a. Data suggest that G. bimaculatus extract may have value in lessening the effects of aging, resulting in a differential gene expression pattern indicative of a marked stress response and lower expression of metabolic and biosynthetic genes.

Fifteen cases of Korean hemorrhagic fever who were admitted Chungnam National University Hospital from October 1981 to December 1981 were analysed on the evaluation of metabolic.changes of the thyroid hormones, and thyroid function status in each clinical phase. 1. Serum $T_3,\;T_4$ concentratron, $FT_4I\;and\;T_4/TBG$ ratio were significantly lower (p<0.001, p<0.005, p<0.005, p<0.001, respectively) than control group in oliguric and early diuretic phase of Korean hemorrhagic fever. With the recovery of illness, abnormal thyroid hormones and thyroid function indices tend to become normal range. But Serum $FT_4$, TSH and TBG concentration were within normal range in all phase of KHF. Thus in Korean hemorrhagic fever, euthyroidism is probably maintained by normal or elevated serum $FT_4$ 2. $T_4/T_3\;and\;rT_3/T_3$ rato (p<0.005, p<0.005) were increased in oliguric and early diuretic phase of KHF. These results might be explained by decreased peripheral conversion of $T_4\;to\;T_3$ in oliguric and early diuretic phase.
