The purpose of this study was to investigate the effect of food habits on blood components level(blood glucose, uric acid, hemoglobin, some lipids levels) and health condition in Taejon. The study was conducted with 250 subjects (male 130, female120) who visited in a general hospital from May to June in 1997. Questionaires were used for food habits. The data were analyzed by using $x^2$-test, t-test, ANOVA and multiple range test. Results were summerized s follow : mean of Broca Index were 110.0 $\pm$13.7% in male, 110.6$\pm$16.6% in female. Mean values of systolic blood pressure and diastolic blood pressure were 130.9$\pm$17.6mmHg, 76.2$\pm$12.6mmHg, respectively. The systolic blood pressure was significantly higher in man than woman, Mean serum total cholesterol, LDL-cholesterol, and HDL-cholesterol and triglyceride levels were 202.8$\pm$40.2, 121.1$\pm$35.5, 50.3$\pm$12.9, 157.1$\pm$112.6mg/dl, respectively. Triglyceride level was significantly higher in man than woman. But HDL-cholesterol was significantly lower in man than woman. And also, the value of LPH and AI were higher in man. So Man has more risk of atherogenesis than woman. Mean values of blood sugar, uric acid and hemoglobin was 102.7$\pm$1.36mg/dl and 14.1$\pm$1.56g/dl were higher in man than woman except blood sugar. Food habit of woman were better than it of man. The levels of education and income did not affect to food habit score. The most problem of habits were intake of salty food and lack of exercise. The intake of nutrients were higher as food habit score was higher. Intakes of energy, Ca, vitamin A and vitamin $B^1$ were lower than RDA's of nutrients in bad food habit group. This result did not show that blood components level and health condition were significantly different by food habits. But Broca Index and triglyceride levels were higher in bad food habit group than other groups, but not statistically significant. By this result, it is more needed food habit education to man and young people. The education of food habits will include the real methods of weight control, low intake of salt and exercise to bad food habit group.

Purpose: In this study, we investigated the effects of chronic alcohol and excessive iron intake on mitochondrial DNA (mtDNA) damage and the progression of alcoholic liver injury in rats. Methods: Twenty-four Sprague-Dawley male rats were divided into four groups (Control, EtOH, Fe, and EtOH + Fe), and fed either control or ethanol (36% of total calories) liquid diet with or without 0.6% carbonyl iron for eight weeks. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, liver malondialdehyde concentrations were measured by colorimetric assays. Liver histopathology was examined by Hematoxylin-eosin staining of the fixed liver tissues. The integrity of the hepatic mtDNA and nuclear DNA was measured by long-range PCR. The gene expression levels of cytochrome c oxidase subunit 1 (Cox1) and NADH dehydrogenase subunit 4 (Nd4) were examined by real-time PCR. Results: Serum ALT and AST activities were significantly higher in the EtOH+Fe group, as compared to the Control group. Similarly, among four groups, liver histology showed the most severe lipid accumulation, inflammation, and necrosis in the EtOH + Fe group. PCR amplification of near-full-length (15.9 kb) mtDNA showed more than 50% loss of full-length product in the liver of the EtOH + Fe group, whereas amounts of PCR products of a nuclear DNA were unaffected. In addition, the changes in the mtDNA integrity showed correlation with reductions in the mRNA levels of mitochondrial gene Cox1 and Nd4. Conclusion: Our data suggested that the liver injury associated with excessive iron and alcohol intake involved mtDNA damage and corresponding mitochondrial dysfunction.

The purpose of this study is to investigate the association of total cholesterol levels (TC) and the incidence of hypercholesterolemia in response to changes in BMI. The subjects included a total of 28,249 industrial workers (25,548 male and 2,701 female) aged 30-69 years old who had received regular medical check-ups at least once per year from 2002 to 2012 (over 11 years). Data from this period were categorized into a first term (2002-2005), middle term (2006-2009), and last term (2010-2012). Then, the average TC was stratified by BMI, which was obtained from the initial examination results of each individual. In addition, average changes in TC were analyzed by stratifying with changes in BMI over 10 years (starting in 2002). The annual occurrence rates of hypercholesterolemia stratified by BMI were further assessed in patients with normal ranges of TC. In all three terms, the average TC was significantly elevated in the obese group ($25.0kg/m^2$) compared to the low weight group ($18.5kg/m^2$) and the normal weight group ($18.5-25.0kg/m^2$). Similarly, the group with higher BMI presented elevated rates of hypercholesterolemia compared to the groups with low BMI. In addition, increased BMI over the 10 year period significantly influenced TC. Consequently, it is suggested that evaluation and intervention for obesity control may be needed in order to manage the risk of high serum lipid levels.

The purpose of this study was to investigate the change of body composition, biochemical index level, resting metabolic rate and daily activities by the public health center's health-promoted program in overweight middle aged women. The workout program of 12 subjects constituted by exercise(aerobic exercise & resistance training) and nutritional education for 10 weeks. As the results, there was a significant decrease in all the weight(59.0$\pm$8.9 vs 57.2$\pm$8.3kg, p<0.05), body fat percentage(33.4$\pm$4.3 vs 30.5$\pm$4.5%, p<0.05) and body fat mass(19.8$\pm$5.4 vs 17.7$\pm$4.9kg, p<0.05) after program. Fat free mass and RMR which tend to be higher after than before program were found not to be significantly. In addition, the serum HDL-cholesterol(54.3$\pm$8.1 vs 59.7$\pm$13.9mg/dl, p<0.05) and TG level(65.2$\pm$418 vs 89.4$\pm$65.6mg/dl, p<0.05) of the subjects increased at the end of the study significantly and significant correlation found between total-cholesterol and TG before program. When the other laboratory parameter were compared before and after program, hematocrit(35.1$\pm$3.3 vs 39.7$\pm$3.3%, p<0.001), platelet(225.9$\pm$49.6 vs 244.3$\pm$49.7cell/ul, p<0.05) and fasting glucose(88.0$\pm$6.5 vs 76.6$\pm$9.7mg/dl, p<0.001) increased significantly but hemoglobin(13.3$\pm$1.3 vs 12.9$\pm$1.3mg/dl, p<0.01) decreased. And in activities analysis, 'moderate activity(18.8 vs 5.8minutes, p<0.05)' clearly showed a significant decrease but 'severe activity(17.7 vs 11.4minutes, p<0.05)' showed a increase. These results suggest that continuous health-promoted program involved exercise and nutritional education at the public health center are effective to reduce body fat and to improve resting metabolic rate(RMR). Further research is required to develop more effective public health program for the middle aged women in community.

Effects of Sotosaja hwan on Blood Glucose, Hyperlipidemia, Polyol Pathway and Antioxidative Mechanism in ob/ob Mouse Diabetes is a disease in which the body does not produce or properly use insulin. Etiological studies of diabetes and its complications showed that oxidative stress might play a major role. Therefore, many efforts have been tried to regulate free oxygen radicals for treating diabetes and its complications. Sotosaja-hwan has been known to be effective for the antiaging and composed of four crude herbs. In male ob/ob mouse in severe obesity, hyperinsulinemia and hyperlipidemia, which are features of NIDDM, the hyperglycemic activites and mechanisms of Sotosaja-hwan were examined. Mice were grouped and treated for 5 weeks as follows. Both the lean (C57/BL6J black mice) and diabetic (ob/ob mice) control groups received standard chow. The experimental groups were fed with a diet of chow supplemented with 30 and 90 mg Sotosaja-hwan per 1 kg of body weight for 14 days. The effects of Sotosaja-hwan extract on the ob/ob mice were observed by measuring the serum levels of glucose, insulin, lipid components, and the kidney levels of superoxide anion radical $({\cdot}O_2)$, MDA+HAE, GSH/GSSG ratio, and also the enzyme activities involved in polyol pathway. Sotosaja-hwan lowered the levels of serum glucose and insulin in a dose dependent manner. Total cholesterol, triglyceride and free fatty acid levels were decreased, while the HDL-cholesterol level was increased, in Sotosaja-hwan treated groups. Renal aldose reductase and sorbitol dehydrogenase activities were increased in the ob/ob mice, whereas those were inhibited in the Sotosaja-hwan-administered groups. Sotosaja-hwan inhibited the generation of ${\cdot}O_2$ in the kidney. Finally, MDA+HAE levels was increased and GSH/GSSG ratio was decreased in the ob/ob mice, whereas those were improved in the Sotosaja-hwan-administered groups. Sotosaja-hwan showed the antidiabetic and anti hyperlipidemic activities by regulating the activities of polyol pathway enzymes, scavenging reactive oxygen species and reducing the MDA+HAE levels in the ob/ob mice.

This study was conducted to determine the effect of feeding betaine on egg production, lipid metabolism and osmoregulation in laying hens. Three hundred and sixty layers were fed corn-soy basal diet containing 16% CP, 2800 kcal/kg ME from 18 to weeks. Hens were provided with betaine 0, 300, 500 or 1200 ppm. Egg production, feed intake, egg weight and feed conversion were examined in every four weeks. Liver and egg betaine. serum cholesterol and neutal fat were measured at the mid experiment. Egg production was not statistically different among treatments from 18 to 26 weeks of age, but significantly increased for the rest of period in hens fed more than 600ppm betaine(P＜0.05). Betaine added treatments showed a tendency to increase feed intake. Feed conversion tended to improve from 26 to 33 weeks old in betaine supplemental groups. Egg qualify was not influenced by dietary supplemental betaine. Betaine supplementation seemed to increase in liver betaine. but not in egg betaine. Serum total cholesterol, triacylglycerol, abdominal fat content and ileal osmolality were not different. However, liver fat content was prone to decrease in betaine supplemental groups. The result of this experiment suggested that dietary supplemtal betaine can improve the egg production and decrease liver fat content.

Cajanus indicus is a herb with medicinal properties and is traditionally used to treat various forms of liver disorders. Present study aimed to evaluate the effect of a 43 kD protein isolated from the leaves of this herb against chloroform induced hepatotoxicity. Male albino mice were intraperitoneally treated with 2mg/kg body weight of the protein for 5 days followed by oral application of chloroform (0.75ml/kg body weight) for 2 days. Different biochemical parameters related to physiology and pathophysiology of liver, such as, serum glutamate pyruvate transaminase and alkaline phosphatase were determined in the murine sera under various experimental conditions. Direct antioxidant role of the protein was also determined from its reaction with Diphenyl picryl hydraxyl radical, superoxide radical and hydrogen peroxide. To find out the mode of action of this protein against chloroform induced liver damage, levels of antioxidant enzymes catalase, superoxide dismutase and glutathione-S-transferase were measured from liver homogenates. Peroxidation of membrane lipids both in vivo and in vitro were also measured as malonaldialdehyde. Finally, histopathological analyses were done from liver sections of control, toxin treated and protein pre- and post-treated (along with the toxin) mice. Levels of serum glutamate pyruvate transaminase and alkaline phosphatase, which showed an elevation in chloroform induced hepatic damage, were brought down near to the normal levels with the protein pretreatment. On the contrary, the levels of anti-oxidant enzymes such as catalase, superoxide dismutase and glutathione-S-transferase that had gone down in mice orally fed with chloroform were significantly elevated in protein pretreated ones. Besides, chloroform induced lipid peroxidation was effectively reduced by protein treatment both in vivo and in vitro. In cell free system the protein effectively quenched diphenyl picryl hydrazyl radical and superoxide radical, though it could not catalyse the breakdown of hydrogen peroxide. Post treatment with the protein for 3 days after 2 days of chloroform administration showed similar results. Histopathological studies indicated that chloroform induced extensive tissue damage was less severe in the mice livers treated with the 43 kD protein prior and post to the toxin administration. Results from all these data suggest that the protein possesses both preventive and curative role against chloroform induced hepatotoxicity and probably acts by an anti-oxidative defense mechanism.

The aim of this study was to analyze the effects of aerobic exercise on the blood lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women. Thirty-six healthy postmenopausal women (mean age, $54.47{\pm}2.50$ years) with >32 % body fat were assigned randomly to an aerobic exercise group (n = 18) or to a "no exercise" control group (n = 18). The subjects' body composition, blood lipid, leptin, ghrelin levels, and HOMA-IR were measured before and after a 16-week line-dancing program. The exercise group showed a significant decrease in body weight, percent body fat, body mass index, visceral fat area, leptin, insulin, glucose, HOMA-IR, total cholesterol, triglycerides, apolipoprotein B, low-density lipoprotein cholesterol, and systolic and diastolic blood pressure. In addition, this group exhibited a significant increase in the apolipoprotein A-I, ghrelin, and high-density lipoprotein cholesterol levels. The energy metabolic factors that influenced the visceral fat included ghrelin, leptin, insulin, glucose, and HOMA-IR. The t-value, which determined the statistical significance of the independent variables, was significant for ghrelin, glucose, insulin, and HOMA-IR (p < 0.05). Regular and continuous aerobic exercise (e.g., line dancing) effectively improved the body composition, visceral fat, serum blood lipids, leptin, ghrelin, and HOMA-IR factors in obese postmenopausal Korean women.

Objective: Rebamipide is a propionic acid derivative that has an action of the inhibition of superoxide production and removal of hydroxyl radical with the sperm incubation and cryopreservation. In the present study, to investigate whether rebamipide is useful to treat male infertility and sterility, the author observed the antioxidative effects in patient with male infertility and also examined its absorption and distribution in rat genital organ. Methods: To measure the distribution of rebamipide in reproductive organ in the rat, carbon indicated rebamipide, $^{14}C-OPC-12759$, was orally administered to 10 Spraque-Dawley rats and its organ concentration in serum, liver, kidney, stomach, duodenum, colon, urinary bladder, seminal vesicle, epididymis and testicle were measured each time after 0.5, 1, 2, 4, 8 and 24 hours by using HPLC fluorescent method. The concentrations in semen were measured by HPLC fluorescent method in a sample of 50 infertile males who took 900 mg of rebamipide daily for 3 months. To measure the antioxidative effect and fertility rate for 3 months, each month before and after the treatment, sperm motility, vitality, the oxygen free radical formation, level of peroxidation, fetilizing capacity of semen sample which were obtained from infertile male patients by masturbation after at least 48 hours abstinence were analyzed by computer assisted semen analyzer, eosin-nigrosin stain, chemiluminescence, thiobarbituric acid method and hypo-osmotic swelling test. Simultaneously in a sample that wanted baby, both pregnancy and delivery were researched. Results: The $^{14}C-OPC-12759$ concentration in the body of white rats was highest in gastrointestinal organ like stomach, smal intestine and duodenum and followed by genital organ like seminal vesicle, testis and epididymis. The rebamipide concentration in semen of infertile males was $220.77{\pm}327.84ng/mL$ (SD) which showed a large deviation but it was higher than serum which was $126{\pm}76ng/mL$ (SD). In the infertile males, after the treatment with rebamipide, the level of seminal reactive oxygen species (ROS) and lipid peroxidation have significantly decreased in duration of the treatment (p<0.05) and sperm vitality and fertilizing capacity except sperm motility significantly improved on post treatment of 2~3 months (p<0.05). Out of the 41 cases who hoped for pregnancy, 15 cases (36.6%) became pregnant and 12 cases had childbrith, 2 cases had miscarriage and one case is ongoing. The side effect was observed in 1 case (2%) which experienced diarrhea but it was lost spontaneously. Conclusions: We conclude from this study that rebamipide showed relatively high tendancy of absorption and excretion in the genital organ. In infertile males who had elevated ROS in semen, by specifically inhibiting the cell damage from the antioxidation, a way to preserve sperm motility, vitality and fertilizing capacity was confirmed.

We investigated the anti-obesity effects of the water extract from Orostachys japonicus in high-fat-fed mice. For the analysis, 24 mice were divided into four groups: normal (N) group, high-fat diet (HFD) group, high-fat diet supplemented with 2.5% O. japonicus (HFD-OJL) group, and high-fat diet supplemented with 5% O. japonicus (HFD-OJH) group. The body weight gain and food efficiency ratio increased with a high-fat diet, but significantly decreased in the HFD-OJ groups compared with those in the HFD group. Levels of serum triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in the HFD-OJH group. The adipocytes within the epididymal adipose tissue were found to have expanded in the HFD group. However, the adipocytes in the HFD-OJ groups were comparable to those of the N group. These results suggest that O. japonicus has potential as an anti-obesity agent by decreasing body weight and lowering the serum lipid levels in obese mice.
