The aims of this study were to evaluate obesity-related dietary behaviors and to determine long-term exercise effects on obesity and blood lipid profiles in elderly Korean subjects. A total of 120 subjects, aged 60-75 yr, were recruited, and obesity-related dietary behaviors were determined. An exercise intervention was conducted with 35 qualified elderly females for 6 months, and body composition and blood lipids were measured 6 times at 4 week intervals. At baseline, mean BMI ($kg/m^2$) was 24.8 for males and 23.1 for females. The females had better eating habits than the males and were more concerned with reading nutrition labels on food products (P < 0.001); they also preferred convenience foods less than the male subjects (P < 0.05). Obese individuals were more likely than overweight or normal weight individuals to misperceive their weight (P < 0.001). Those with a high BMI responded feeling more depressed (P < 0.01), lacking self-confidence (P < 0.01), and feeling isolated (P < 0.01) as well as having more difficulty doing outdoor activities (P < 0.01). After exercise, body fat (%) and WHR were significantly reduced (P < 0.05), while body weight and BMI were also decreased without statistical significance. Total cholesterol and blood HDL were significantly improved (207.1 mg/dl vs. 182.6 mg/dl, HDL: 45.6 mg/dl vs. 50.6 mg/dl, P < 0.05). Other benefits obtained from exercise were improvements in self-confidence (26.4%), movement (22.6%), stress-relief (18.9%), and depression (13.2%). In conclusion, elderly females had better eating habits and were more concerned with nutrition information and healthy diets compared to elderly males. However, misperceptions of weight and obesity-related stress tended to be very high in females who were overweight and obese, which can be a barrier to maintain normal weight. Long-term Danhak practice, a traditional Korean exercise, was effective at reducing body fat (%) and abdominal obesity, and improved lipid profiles, self-confidence, and stress.

A variety of studies show that a centraized rather than a generalized pattern of subcutaneous fat distribution is more directly associated with disorers of carbohydrate and lipid metabolism, as possibly hypertension, This study was an attempt to observe the relationship of body fat distribution, blood lipids, blood pressure and exercise in 85 healthy men and women. Within this group there was a gradation of fat distribution progressing from LBSO and UBSO defined on the basis of WHR. This paper reports the relationship of body fat distribution defined by WHR to plasma glucose, lipids, blood pressure, and exercise in this population. Although the obesity indices(RBW and BMI) were slightly higher in the UBSO group, significant differences existed between UBSO and LBSO groups with respect to WHR blood pressure, and total cholesterol concentration in female. WHR values were substantially different and this was primarily due to greater degrees of differences in waist as opposed to hips circum ference. Although no significant differences existed between UBSO and LBSO groups with respect to age, body weight, and hips circumference, energy intake, total cholesterol, LDL-cholesterol and WHR values were substantially different in male. Positive, significant correlations were found between WHR and both systolic and diastolic blood pressure and between WHR and the total plasma cholesterol concentration and age. When 26 pairs of exercise and nonexercise groups were matched according to sex, age and body weight, blood pressure and blood lipids were significantly lower in the exercise groups than those in the nonexercise groups. In conclusion, these findings suggest that an altered blood lipid profiles will manifast in men and women with upper body obese. Furthermore these findings suggest that exercise and physical activity may be beneficial for controlling blood lipids and blood pressure in healthy adults.

Backgrounds Diabetes mellitus is associated with accelerated atherosc lerosis and predispose to specific microvascular problems. This study was performed to evaluate the usefulness of red ginseng as adjunctive therapeutic agent of NIDDM especially in preventing chronic diabetic complications. Materials and Methods We treated 50 patients with NIDDM for 5 month with 2 regimens: 1)oralhypoglycemic drug therapy only(the control group), 2)oral hypoglycemic group). The patients were recruited at Korea university hospital from June, 1992 to October, 1992 and the following inclusion criteria were used: l)age above 35 years 2)initial body weight within or above ideal body weight 3)fasting blood glucose level greater than 140mg/dl 4)no previous history of diabetes mellitus or no history of blood glucose control for recent 3 months of more. The patients were seen every 2 weeks for remaining 3 months. At every visit FBS and PP2hr blood glucose were measured with blood pressure and body weight. Lipid profiles were checked every 4 weeks and platelet function test was perfomed with aggregometer after administration of ADP, epineprine and collagen every 4 weeks. Free fatty acid were also analyzed every 8 weeks and glycosylated hemoglobin was measured every 12 weeks. Results The results were as follows: 1. The mean values for fasting and PP2hr blood glucose decreased significantly in the control group than in the ginseng group. 2. The weight gain was less in the ginseng group than in the control group. The levels of systolic blood pressure decreased' significantly in the ginseng group than in the control group. 3. There was no significant differences of lipid profiles in both groups. 4. The platelet hyperaggregation was improved more significantly in the ginseng group than in the control group. Conclusions In patients with NIDDM who were recieving oral hypoglycemic drug therapy, the addition of red ginseng improved platelet function and blood pressure, but induced less weight gain. The data suggests that red ginseng may be useful as a therapeutic adjunct especially in preventing chronic complications of NIDDM.

The purpose of this study was to evaluate whether a daily regimen of green vegetable drink supplementation to male subjects improves the blood pressure and enhances other antioxidant enzyme status, lipid profiles and liver functionalities. Twenty nonsmokers and 19 smokers aged $23{\sim}60$ were given 240 mL of green vegetable drink every day for 8 weeks in addition to their normal diet, and blood samples were drawn before and after the intervention. The 8 weeks of green vegetable drink consumption resulted in a significant decrease of diastolic blood pressure in smokers (p<0.05) as well as in nonsmokers (p<0.01), and systolic blood pressure in smokers (p<0.05). Erythrocyte superoxide dismutase (SOD) activity was significantly increased in both nonsmokers and smokers after the trials. Plasma total cholesterol (TC) level was decreased in smokers and plasma TC and LDL-cholesterol (LDL-C) levels were decreased in nonsmokers while triglyceride (TG) and HDL-cholesterol (HDL-C) was not affected in both nonsmokers and smokers by green vegetable drink consumption. Plasma glutamic pyruvic transaminase (GPT), a marker of liver function was significantly reduced in both nonsmokers and smokers and plasma glutamic oxaloacetic transaminase (GOT) level was significantly reduced in nonsmokers after the supplementation. These results support the hypothesis that green vegetable drink exerts a blood pressure reducing effect and affects not only the activity of antioxidant enzymes, lipid profiles but also plasma GOT and/or GPT levels.

The purpose of this study was carried out to examine the effects of onion kimchi extract supplementation on blood glucose level and serum lipid components in streptozotocin (STZ)-induced diabetic rats for 4 weeks. STZ was administered as a single dose (50 mg/kg BW) to induce diabetes, and the diabetic rats were divided into eight groups (normal, diabetic control, and six treatment groups). The dose of onion kimchi extract 100 (OK-100), 200 (OK-200), and 400 (OK-400) mg/kg/day or quercetin as a main compound of onion 5 (Q-5), 10 (Q-10), and 20 (Q-20) mg/kg/day were orally administered daily to STZ-induced diabetic rats for 4 weeks after STZ injection. The diabetic control rats (465.6 mg/dL) showed significantly higher blood glucose level than the normal rats (76.3 mg/dL) after 4 weeks, but was significantly reduced with onion kimchi extract and quercetin supplementation (p<0.001). Changes in body weight, kidney weight and urine volume were not significantly different in diabetic control rats, and in onion kimchi extract and quercetin treated rats. The serum total cholesterol levels of control were significantly decreased in onion kimchi extract and quercetin supplementation groups, respectively (p<0.001). The blood urea nitrogen level and urinary protein excretion in diabetic rats were not significant different among the groups. These results suggest that onion kimchi extract supplementation in STZ-induced diabetic rats may be a very important factor for the reduction of blood glucose and serum cholesterol profiles.

Objective: The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. Methods: In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; $D_1$ (control), $D_2$ ($D_1$ with 1 mL multivitamin/liter water), $D_3$ ($D_1$ with 1 mL acidifier/liter water), $D_4$ ($D_1$ with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; $T_1$ (control), $T_2$ (5% Azolla in the diet), $T_3$ (7% Azolla in the diet) and $T_4$ ($T_1$ with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days. Results: In experiment 1, the highest live weight was observed in $D_4$ (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in $T_4$. Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, $T_2$ was the best performing dietary group followed by $T_3$, $T_1$, and $T_4$, respectively. The lowest lipid profiles were observed in $D_3$ followed by $D_1$, $D_4$, and $D_2$, respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in $T_2$, followed by $T_3$, $T_1$, and $T_4$, respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in $T_2$ followed by $T_3$, $T_4$, and $T_1$, respectively (p>0.05). Conclusion: In conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.

Oxidative stress leads to the induction of cellular oxidative damage, which may cause adverse modifications of DNA, proteins, and lipids. The production of reactive species during oxidative stress contributes to the pathogenesis of many diseases. Antioxidant defenses can neutralize reactive oxygen species and protect against oxidative damage. The aim of this study was to assess the antioxidant status and the degree of DNA damage in Korean young adults using glutathione s-transferase (GST) polymorphisms. The GSTM1 and GSTT1 genotypes were characterized in 245 healthy young adults by smoking status, and their oxidative DNA damage in lymphocytes and antioxidant status were assessed by GST genotype. General characteristics were investigated by simple questionnaire. From the blood of the subjects, GST genotypes; degree of DNA damage in lymphocytes; the erythrocyte activities of superoxide dismutase, catalase, and glutathione peroxidase; plasma concentrations of total peroxyl radical-trapping potential (TRAP), vitamin C, ${\alpha}$- and ${\gamma}$-tocopherol, ${\alpha}$- and ${\beta}$-carotene and cryptoxanthin, as well as plasma lipid profiles, conjugated diene (CD), GOT, and GPT were analyzed. Of the 245 subjects studied, 23.2% were GSTM1 wild genotypes and 33.4% were GSTT1 wild genotype. No difference in erythrocyte activities of superoxide dismutase, catalase, or glutathione peroxidase, and the plasma TRAP level, CD, GOT, and GPT levels were observed between smokers and non-smokers categorized by GSTM1 or GSTT1 genotype. Plasma levels of ${\alpha}$- and ${\gamma}$-tocopherol increased significantly in smokers with the GSTT1 wild genotype (p < 0.05); however, plasma level of ${\alpha}$-carotene decreased significantly in non-smokers with the GSTM1 wild genotype (p < 0.05). DNA damage assessed by the Comet assay was significantly higher in non-smokers with the GSTM1 genotype; whereas DNA damage was significantly lower in non-smokers with the GSTT1 genotype. Total cholesterol and LDL cholesterol levels were significantly higher in non-smokers with the GSTT1 genotype than those with the GSTT1 wild genotype (p < 0.05). In conclusion, the GSTM1 genotype or the GSTT1 wild genotype in non-smokers aggravated their antioxidant status through DNA damage of lymphocytes; however, the GSTT1 wild type in non-smokers had normal plasma total cholesterol and LDL-cholesterol levels. This finding confirms that GST polymorphisms could be an important determinant of antioxidant status and plasma lipid profiles in non-smoking young adults. Further study is necessary to clarify the antioxidant status and/or lipid profiles of smokers with the GST polymorphism and to conduct a study with significantly more subjects.

This study surveyed 146 obese elementary school children(94 male and 52 female) in Seoul, and measured height, body weight, degree of obesity, blood pressure, fasting blood sugar, serum lipid profiles and liver function. The hypertension was above 95 percentile depending on age and sex. and the hyperglycemia was defined as above 110mg/dl. The hypercholesterolemia and hypertriglyceridemia were defined as above 200mg/dl, 160mg/dl, repectively. The abnormal liver function was considered as elevated alanine aminotransferase(ALT>35IU/L)or aspartate aminotransferase(AST>35IU/L). The results were as follows: 1. The mean degree of obesity was $29.56\pm12.56\%$, and the percentage of overweight was $18.5\%$, mild obesity $41.1\%$, moderate obesity $35.6\%$, severe obesity $4.8\%$ respectively in surveyed children. 2. The systolic blood pressure was $108.34\pm13.73mmHg$, diastolic blood pressure was $67.46\pm8.27mmHg$. 3. FBS was $93.79\pm6.51mg/dl$. 4. Total cholesterol, triglyceride, ALT and AST were $183.34\pm31.38mg/dl$. $115.55\pm56.43mg/dl,\;24.08\pm18.42IU/L,\; 28.73\pm10.45IU/L,$ respectively. 5. The prevalence of complications was $47.2\%$ : hypertension$(13\%)$, hyperglycemia$(0.7\%)$, hypercholesterolemia$(23.3\%)$, hypertriglyceridemia$(17.1\%)$, and liver dysfunction$(21.9\%)$. In conclusion. childhood obesity is associated with various risk factors. Therefore, the aggressive approaches to successful prevention, early detection, and effective treatment of obesity in children are urgently required.

Several studies revealed that low calcium intake is related to high prevalence of cardiovascular diseases such as hypertension. The prevalence of hypertension is high in Koreans along with their low dietary calcium consumption. Thus, the aim of this study was to evaluate the status of calcium intake between the hypertension and normotension groups and to investigate the correlation between dietary calcium intake and blood pressure, blood lipid parameters, and blood/urine oxidative stress indices. A total of 166 adult subjects participated in this study and were assigned to one of two study groups: a hypertension group (n = 83) who had 140 mmHg or higher in systolic blood pressure (SBP) or 90 mmHg or higher in diastolic blood pressure (DBP), and an age- and sex-matched normotension group (n = 83, 120 mmHg or less SBP and 80 mmHg or less DBP). The hypertension group consumed 360.5 mg calcium per day, which was lower than that of the normotension group (429.9 mg) but not showing significant difference. In the hypertension group, DBP had a significant negative correlation with plant calcium (P < 0.01) after adjusting for age, gender, body mass index (BMI), and energy intake. In the normotension group, total calcium and animal calcium intake were significantly and positively correlated with serum triglycerides. No significant relationship was found between calcium intake and blood/urine oxidative stress indices in both groups. Overall, these data suggest reconsideration of food sources for calcium consumption in management of the blood pressure or blood lipid profiles in both hypertensive and normotensive subjects.

Diospyros peregrina Gurke. (Ebenaceae) is a small middle sized tree grows luxuriantly in the plains of costal West Bengal, India. The objective of the study was to explore the antidiabetic activity of methanol extract of matured fruits of Diospyros peregrina to substantiate the folklore claim of traditional practitioners. It was also aimed to establish correlation with reduction of oxidative state associated with diabetes. Methanol extract of matured fruits of Diospyros peregrina was administered orally at doses of 150 and 300 mg/kg body weight for 12 consecutive days to normal and streptozotocin induced diabetic rats. Fasting blood glucose level was estimated in both normal and diabetic rats while serum lipid profiles, liver glycogen level and pancreatic thiobarbituric acid reactive substances (TBARS) were evaluated for diabetic rats. Initial and final changes in body weight were also recorded. Oral glucose tolerance test was performed during the course of study. Experimental findings showed significant antidiabetic potential of extract in term of reduction of fasting blood glucose level of both normal and diabetic rats. It was found that extract at the dose of 300 mg/kg body weight is more effective and percentage reduction (55.64) of elevated blood glucose level is comparable to that of standard drug glibenclamide (60.60) at a dose of 10 mg/kg body weight. Observed data found statistically significant in reduction of serum lipid and pancreatic TBARS levels whilst improvement was observed in liver glycogen level and body weight profiles in extract treated diabetic rats.
