  • This study investigated the possible improvement in the antioxidative status and quality characteristics of ready-to-eat (RTE) Samgyetang after adding various black garlic (BG) extracts. The antioxidant activity, total phenolic content (TPC), total flavonoid content (TFC), meat quality indexes, and lipid oxidation rates were measured after receiving one of five different treatments consisting of conventional Samgyetang broth as a negative control, raw garlic (RG) extract as a positive control, BG, oven-dried BG, and maltodextrin-encapsulated BG extract as treatments. Employing retort cooking, fat trimmed carcasses were added to the initially prepared broth together with a phenolic extract that was set at 5% (w/w). A significant intensification of red and yellow color was observed in breast and thigh meat treated with BG extracts, regardless of pretreatment, compared to the negative control and RG. The moisture percentage was affected by the addition of BG extracts, where the encapsulation group retained the highest water content after retorting. In terms of antioxidative status, maltodextrin-encapsulated BG extract was as effective as an oven-dried extract to scavenge free radicals and showed the highest score among samples (p<0.01). The concentration of TFC was found to be the highest and did not differ between encapsulation and oven-dried groups, followed by BG, RG, and the negative control. However, the addition of encapsulated BG extract was the most effective in delaying the formation of malondialdehyde among the samples. Therefore, pre-treatment of BG extract through encapsulation is recommended to develop a higher antioxidative status and quality characteristics of Samgyetang.

  • BACKGROUND/OBJECTIVES: Glutathione S-transferase (GST) forms a multigene family of phase II detoxification enzymes which are involved in the detoxification of xenobiotics by conjugating substances with glutathione. The aim of this study is to assess the antioxidative status and the degree of DNA damage in the subclinical hypertensive patients in Korea using glutathione S-transferase polymorphisms. SUBJECTS/METHODS: We examined whether DNA damage and antioxidative status show a difference between GSTM1 or GSTT1 genotype in 227 newly diagnosed, untreated (systolic blood pressure $(BP){\geq}130mmHg$ or diastolic $BP{\geq}85mmHg$) subclinical hypertensive patients and 130 normotensive subjects (systolic BP < 120 mmHg and diastolic BP < 80 mmHg). From the blood of the subjects, the degree of the DNA damage in lymphocyte, the activities of erythrocyte superoxide dismutase, the catalase, and the glutathione peroxidase, the level of glutathione, plasma total radical-trapping antioxidant potential (TRAP), anti-oxidative vitamins, as well as plasma lipid profiles and conjugated diene (CD) were analyzed. RESULTS: Of the 227 subjects studied, 68.3% were GSTM1 null genotype and 66.5% were GSTT1 null genotype. GSTM1 null genotype had an increased risk of hypertension (OR: 2.104, CI: 1.38-3.35), but no significant association in GSTT1 null genotype (OR 0.982, CI: 0.62-1.55). No difference in erythrocyte activities of superoxide dismutase, catalase, or glutathione peroxidase, and plasma TRAP, CD, lipid profiles, and GSH levels were observed between GSTM1 or GSTT1 genotype. Plasma levels of ${\alpha}-tocopherol$ increased significantly in GSTT1 wild genotype (P < 0.05); however, plasma level of ${\beta}-carotene$ increased significantly in GSTT1 null genotype (P < 0.01). DNA damage assessed by the Comet assay was significantly higher in GSTM1 null genotype than wild genotype (P < 0.05). CONCLUSIONS: These results confirm the association between GSTM1 null genotype and risk of hypertension as they suggest that GSTM1 null genotype leads to an increased oxidative stress compared with wild genotype.

  • Objective: The goal of this study was to investigate the effects of cupric citrate (CuCit) on growth performance, antioxidant indices, serum lipid metabolites, serum immune indices, and tissue residues of copper (Cu), zinc, and iron in weaned pigs. Methods: A total of 180 weaned pigs ($Duroc{\times}Landrace{\times}Large$ White) with an average body weight of $8.98{\pm}1.21kg$ were randomly assigned to a corn-soybean meal control ration, or 4 similar rations with 30, 60, 120, or 240 mg/kg Cu as CuCit. All diets contained 10 mg/kg Cu as cupric sulfate from the vitamin-mineral premix. The experiment was divided into two phases: 0 to 14 d (phase 1) and 15 to 28 d (phase 2). Results: Average daily gain (ADG; linearly, p<0.01) and average daily feed intake (ADFI; linearly and quadratically, p<0.05) were affected by an increase in CuCit during phase 2. Overall period, ADG (p<0.05) and ADFI (p<0.01) were linearly increased with increasing dietary levels of CuCit. Serum malondialdehyde concentrations (p<0.05) and glutathione peroxidase activity (p<0.01) linearly decreased and increased respectively with an increase in CuCit. Serum levels of Cu-Zn superoxide dismutase were linearly affected with an increase in CuCit (p<0.01). Hepatic malondialdehyde levels decreased with an increase in CuCit (linearly and quadratically, p<0.01). Serum total cholesterol concentrations were quadratically affected (p<0.05) and decreased in pigs fed Cu as CuCit at 60 and 120 mg/kg and increased in pigs fed 240 mg/kg Cu as CuCit. Serum high-density lipoprotein concentrations were linearly affected with an increase in CuCit (p<0.01). Serum $IL-1{\beta}$ levels were quadratically affected (p<0.05) by dietary treatment. Compared with other treatments, 240 mg/kg Cu from CuCit quadratically increased hepatic (p<0.01) and renal (p<0.05) Cu concentrations, and quadratically decreased hepatic and renal iron concentrations (p<0.05). Conclusion: Cu administered in the form of CuCit at a dosage range of 30 to 60 mg/kg, effectively enhanced the growth performance and antioxidant status of weaned pigs.

  • The purpose of this study was to investigate the effect of food behavior on dietary food intake status and health condition based on research of food behavior and nutritional intake status of university students in the Chungnam area. The average age, height, and weight of the subject group were 22.1 years old, 174.2 cm, and 67.0 kg for the male students and 20.9 years old, 161.8 cm, and 53.4 kg for the female students, respectively. From the nutritional intake status data, the averaged daily energy intake of both groups, male and female, are lower than the dietary reference intake(KDRI), as 2,169.2 kcal and 1,846.2 kcal, males and females, respectively. The lipid intake ratio was higher than the dietary reference figure, and the carbohydrate intake ratio was determined to be in the proper range. Male students(54.6%) and female students(52.0%) of the entire subject group skipped a breakfast mainly due to insufficient time, and the time at which meals were consumed, was determined to be irregular generally. In a day, male and female students have a heavier dinner than lunch(p<0.05), respectively. Meat and fishes are preferred by the entire subject group, and the number of students, who do not eat carrot and mayonnaise(p<0.05), was determined to be the highest, of all foods surveyed. The averaged daily activity coefficient and the resting energy expenditure shows significant difference(p<0.001) between two groups; was 1.7 and 1.6 and the second was 1,404.3 kcal/day and 1,292.5 kcal/day for the male and female groups, respectively. As the number of attempting to reduce body weight(p<0.001), the amount smoking(p<0.001), or the frequency of drinking alcohol increases, BMI decreases. On the other hand, as body shape satisfaction increases, BMI increases also.

  • Objectives & Method:Based on the statistic from January 2008 to December 2008 include 66-year-old 375 people (159 men, 216 women) who got examined in National Health Insurance Corporation, this study set a goal to establish a new health index by analyzing the relation between the cardio-cerebra vascular disease and risk factor such as obesity, smoking, exercise, alcohol consumption, blood pressure, blood sugar and cholesterol. Results:1) Examine results, health status according to gender;People who are diagnosed as abnormal health status have higher risk for both men and women. As for the detailed diseases, high blood pressure was highest followed by hyperlipidemia and obesity. In case of the women, 96.3% in bone mineral density was highest. 2) Correlation of disease and health risk factors based on gender;Correlation of disease according to gender in the obesity(p<0.001), lipid abnormalities(p<0.001), kidney diseases(p<0.001), chest diseases(p<0.05), osteoporosis(p<0.001) showed a statistically significant difference. The analysis showed that the men have more obesity and lipid abnormalities as well as thoracic disease than the women, but the women have more kidney disease than the men. As for the osteoporosis examine which is conducted only for the women, most of the women were abnormal even though it cannot compare the result according to gender. Obesity(p<0.001), alcohol(p<0.001), smoking(p<0.001) and LDLcholesterol(p<0.001) showed statistical correlation between gender and health risk factor. And only high blood pressure(p<0.001) showed a statistical correlation between gender and risk of cardio-cerebra vascular disease. 3) Risk of cardio-cerebra vascular disease related to health risk factor characteristic;Obesity assessment(p<0.001), alcohol(p<0.05), smoking(p<0.05), blood pressure(p<0.001), glucose(p<0.001) showed correlation between health risk factor and stroke. Drinking(p<0.001), smoking(p<0.05), exercise(p<0.001), blood pressure(p<0.001), LDL cholesterol(p<0.001) showed health risk factor and myocardial infarction. Obesity assessment(p<0.001), smoking(p<0.05), blood pressure(p<0.001), glucose(p<0.001) and showed correlation between health risk factor and diabetes. Obesity assessment(p<0.001), blood pressure(p<0.001) showed correlation between health risk factor and high blood pressure. Conclusion:Therefore, we have to take one step farther after the health examination. In order to prevent and reduce the risk of disease, people have to understand their health status exactly first, and correct their habit with recognizing the amount of risk related to cardio-cerebra vascular disease.

  • This study investigated the relaxation effects of Crataegi Fructus(CF, Crataegus pinnatifida Bunge) on the contraction evoked by phenylephrine in rabbit carotid artery, and also analyzes antioxidative status in vitro. CF revealed siginificant relaxation on phenylephrine-induced arterial contraction. It's relaxant effect statistically significant in both in the presence of endothelium and absence of endothelium, but statistically exerted more strong relaxation in the presence of endothelium. CF increased in vitro nitric oxide(NO) production in dose-dependent manner. Also, they reduced malondiaidehyde(MDA) concentrations, phosphatidyl choline-liposome(PCOOH) contents, linoleic acid-induced lipid peroxidation and exerted 1,1-diphenyl-2- picryl-hydrazyl(DPPH) radical scavenging effect, in vitro. These results indicate that Crataegi Fructus would be effective in relaxing arterial contraction and it's antioxidative effects may be involved in endothelium-dependent relaxation of artery via vascular protective properites.

  • The aim of the study was to investigate the chemopreventive potential of andrographolide in 7,12-dimethylbenz(a) anthracene (DMBA)-induced hamster buccal pouch carcinogenesis. Oral tumors developed in the buccal pouch of golden Syrian hamsters at a 100% incidence on painting with 0.5% DMBA in liquid paraffin three times a week for 14 weeks. Marked abnormalities in the status of detoxification enzymes, lipid perxodiation and antioxidants were noticed in hamsters treated with DMBA alone. Oral administration of andrographolide at a dose of 50 mg/kg bw to hamsters treated with DMBA not only completely prevented the tumor formation but also restored the status of the above mentioned biomarkers. The present study thus demonstrates the chemopreventive potential of andrographolide in DMBA-induced hamster buccal pouch carcinogenesis, which is probably due to its antioxidant potential as well as modulating effect on xenobiotic metabolising enzymes during DMBA-induced oral carcinogenesis.

  • The purpose of this study was to compare the anthropometry, serum lipid levels, dietary behavior and health-related behaviors of shipbuilding workers. The education level was significantly higher in office workers than laborers, while age, monthly income and working years were not significantly different between both groups. The serum triglyceride, glucose concentration and AI were significantly higher in office workers than in laborers, but the serum LDL-cholesterol and HDL-cholesterol concentrations were significantly higher in laborers than in office workers. The frequency of breakfast and coffee intake was significantly higher in office workers than in laborers. In the office workers, age was positively correlated with systolic blood pressure but was negatively correlated with hemoglobin and hematocrit concentration In the laborers, working year was negatively correlated with hemoglobin, total cholesterol and serum LDL-cholesterol concentrations. Exercise was negatively correlated with total cholesterol concentration, triglyceride and LDL-cholesterol concentration and AI in the office workers. The results of this study showed that office workers are more prone to related chronic degenerative diseases. Therefore, nutritional education for the provention of chronic degenerative diseases of shipbuilding workers needs to be more focused on improving the health status of office workers.

  • This study was done to investigate and compare the nutritional status and plasma lipids in the diabetes and control elderly. Subjects were 105 persons (male 32, female 73) aged over 65 years and visited public health centers in Ulsan area. The subjects were divided into 2 groups, diabetes and control group. Athropometric measurement, dietary intakes, and plasma biochemical indices were examined. Body Mass Index (BMI), Percentage of Ideal Body Weight (PIBW) and Waist-Hip Ratio (WHR) of diabetes group were higher than those of control group. Overall eating behavior were worse in diabetes group than those of control group. There was no significant difference in smoking and exercise status among groups. The ratio of drinkers was significantly higher in control group. But the amount of alcohol consumed at once was higher in the diabetes group. There was no significant difference in most nutrient intakes between males and females. The intakes of fiber, natrium (Na), vitamin A, and $\beta$-carotene were significantly higher in diabetes group than control groups while that of potassium (K) was lower in diabetes group. Diabetes group had the higher levels in triglyceride, VLDL-cholesterol, Chol/HDL-cholesterol ratio, LDL/HDL-cholesterol ratio, while they had lower HDL-cholesterol level. Overall results might imply that the elderly with diabetes have to be more careful to their meals and health-related behaviors to increase the likelihood of a healthier life.
