The goal of this study was to find out the effective diet prescription for the exercises. To accomplish this purpose, we investigated the effect of free-fatty acid diet (FFAD) on two groups of the K technical high school soccer players; one group with 7 members for normal diet (NORD) and another group with 7 members for high-fat diet (HFD). HFD group was fed far three days before the game. Results were as follows: i) Blood glucose level was increased with statistical significance in HFD group (P<.01) compared to the NORD group. After plying game, the glucose level was increased in the both groups ii) The contents of free-fatty acid (FFA) was significantly increased in HFD group (P<.0001) compared to the NORD group. After playing game, the FFA level was also increased in both groups iii) The levels of T-C, HDL-C and LDL-C were slightly increased in both NORD and HFD groups after playing game, while the TG level was slightly decreased. However, the differences were not significant. These results imply that HFD may not affect the level of seam lipids. Overall, the level of glucose and FFA were increased, but other types of lpids were not changed. From these studies, we observed the increase in the level of glucose and FFA but not other sew lipid. These results indicate that HFD may induce the body energy-utilizing system during long-lasting exercise such as playing soccer game.

This study examined the effects of a brown rice vegetarian diet and outdoor walking exercise program on body composition and blood lipid parameters in collegians. The mean age of respondents was 21.8 yrs (males) and 21.7 yrs (females). During the ten-day program, the respondents lived in a dormitory and had three meals. The respondents exercised one hour in the morning (6:20~7:20 am) and attended one and a half hour evening lecture (7:00~8:30 pm) everyday. The brown rice vegetarian diet consisted of brown rice, whole grain bread, beans, fresh vegetables, and fresh fruits contained $2043.2{\pm}112.7$ kcal (97.3% of RNI), 66.7 g protein (133.3% of RNI), 33.6 g dietary fiber (168.2% of RNI), vitamin A (194.2% of RNI), vitamin $B_1$(245.5% of RNI), vitamin $B_2$(225.1% of RNI), niacin (233.7% of RNI), vitamin $B_6$(277.1% of RNI), folic acid (128.4% of RNI), vitamin C (334.6% of RNI), iron (131.9% of RNI), zinc (112.4% of RNI) and calcium (60.3% of RNI). The results showed that there were significant increases in body weight (P<0.05) and BMI (P<0.05) in males and body weight (P<0.05) and lean body mass (P<0.01) in females. In addition, there were significant decreases in total cholesterol (P<0.001), LDL cholesterol (P<0.001), TG (P<0.05), and HDL-cholesterol (P<0.001) in males and total cholesterol (P<0.01) and LDL-cholesterol (P<0.01) in female. The ten day brown rice vegetarian diet rich in fiber and outdoor walking exercise program significantly increased body weight and decreased total cholesterol and LDL-cholesterol in collegians.

The present study investigated the effect of silymarin, a flavonoid, on streptozotocin (STZ) - induced diabetic dyslipidaemia in rats. Experimental diabetes was induced by a single intraperitoneal injection of STZ (60 mg/kg). Silymarin (25 mg/kg and 50 mg/kg) was orally administered to diabetic rats for a period of 15 days. Blood glucose levels, serum lipid profile and liver glycogen levels were estimated following the established procedures. Biochemical observations were supplemented with histological examination of liver sections. Oral administration of silymarin to diabetic rats significantly (P < 0.001) decreased the blood glucose levels ($259.99{\pm}23.64$ vs. $99.90{\pm}2.62$ [25 mg] & $89.17{\pm}3.32$ [50 mg]). The most interesting finding was the significant (p < 0.001) increase in HDL-cholesterol levels ($26.99{\pm}0.61$ vs. $40.55{\pm}0.52$ [25 mg] & $41.12{\pm}0.37$ [50 mg]) whereas, there was a significant decrease in serum total cholesterol (TCh), triglycerides (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) cholesterol levels observed in silymarin treated diabetic rats. STZ treatment caused significant degeneration of liver parenchyma, which was normalized to near normal morphology by administration of silymarin. The findings indicate that silymarin effectively improved the overall lipid profile and restored the glycogen stores in the liver of STZ-induced diabetic rats, in a dose dependent manner. The results indicate existence of abnormalities in lipid metabolism in STZ-induced diabetic rats and suggest a protective effect of silymarin in this animal model.

Objective : Previous studies reported a correlation between the low serum cholesterol level and impulsive behaviors. In this study, we investigate an association between the serum lipid levels and psychological parameters in maladaptive soldiers in the Korean Army. Methods : A total of ninety-six maladaptive subjects and thirty-six normal controls in the Korean army were evaluated with the Korean version of Barratt Impulsiveness Scale (K-BIS), Korean version of Beck Suicidal Ideation Scale (K- BSIS), Korean version of Beck Depression Inventory (K-BDI) and Korean version of Beck Anxiety Inventory (K-BAI). Serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) level were measured by overnight fasting blood sampling. Results : There were no significant differences between the groups in demographic characteristics. Serum total cholesterol levels (t=-2.209, p=0.032), triglyceride levels (t=-4.593, p<0.001), and LDL levels (t=-3.753, p=0.001) of maladaptive subjects were significantly lower than those of normal controls, and maladaptive subjects had higher K-BIS scores than normal controls (t=7.542, p<0.001). Negative correlation was found between LDL levels and non-planning impulsiveness in the maladaptive subjects (r=-0.253, p=0.013). LDL levels (${\beta}=-0.258$, p=0.008) and K-BDI scores (${\beta}=0.266$, p=0.043) emerged as significant predictors for non-planning impulsiveness. Conclusion : These results suggested that LDL level was associated with non-planning impulsiveness. These findings suggested that serum cholesterol levels might be available as a biological marker of impulsiveness. However, more large samples, longitudinal biological study and psychiatric evaluations should be needed to develop a preventive intervention for maladaptive male conscripts in the Korean army.

This study investigated the efficacy of macelignan and hot water with Chinese traditional herb (CTH) extract on altering severe diabetic conditions in C57BL/KsJ-db/db mice. Previously, the anti-diabetic effects of macelignan were partly reported as a PPAR $\alpha/\gamma$-dual agonist. Here, we futher studied whether a combination of macelignan and CTH had more beneficial effects or not. The macelignan and CTH compound significantly decreased fasting blood glucose and HbA1c compared to macelignan-treated mice, and also significantly improved postprandial glucose, insulin sensitivity, and plasma lipid profiles (FFA, and TG). On the other hand, insulin levels were not significantly changed compared to the diabetic control group. There were no significant changes in the concentrations of total cholesterol and HDL-cholesterol, but there were changes in HTR and AI. These results suggest that the macelignan and CTH compound ameliorates hyperglycemia and efficiently improves postprandial glucose, insulin sensitivity, and hyperlipidemia compared with macelignan in db/db mice. Moreover, the macelignan and CTH compound seems to be more potent in affecting diabetic complications than macelignan.

This study was designed to investigate the effects of mulberry leaf extract (MLE) on oxygen radicals and their scavenger enzymes in serum of rats. Sprague-Dawley (SD) male rats (160${\pm}$10g) were fed experimental diets (MLE-100 and MLE-300 groups) added 100 and 300mg/kg BW/day for 6weeks. Triglyceride (TG) levels were significantly inhibited (10% and 20%) in MLE-100and MLE-300 groups, but there were no significant differences in total, LDL-and HDL- cholesterol levels in both MLE-100 and MLE-300 groups. Hydroxyl radical ($.$OH) formations resulted in a marked decreases(20∼25%) in MLE-100 and MLE-300 groups compared with control group, while superoxide radical (O2.-)and hydrogen peroxide formations resulted in a considerable decreases(7∼10% and 5∼10%) in MLE-100 and MLE-300 groups compared with control group. Lipid peroxide (LPO)and oxidized protein(>C=O group) productions resulted in a significant decreases (10% and 6∼10%) in MLE-100 and MLE-300 groups compared with control group. Superoxide dismutase (SOD)and catalase (CAT) activities were remarkably increased (30% and 40∼55%) in MLE-100 and MLE-300 groups, but glutathione peroxidase (GSHPX) activities were significantly increased (10∼15%) in MLE-100 and MLE-300 groups compared with control group. These results suggest that anti-aging effect of mulberry leaf extract (MLE) may play a pivotal role in attenuating a various agerelated changes.

Objectives : This study aimed to analyze the living habits and results of health examinations of university students according to Sasang constitution. Methods : We measured the height, weight, body mass index, and blood pressure of 2,387 university students, performed laboratory examinations, and conducted a questionnaire survey of their eating, drinking, smoking, and exercise habits. Their Sasang constitution was diagnosed by using the Questionnaire of Sasang Constitution ClassII(QSCCII). All the data were analysed statistically by descriptive statistics, chi-square test, ANOVA, tukey's multiple comparisons Results : The Taeeumin group mostly ranged in overweight sector of the BMI, and this group showed significantly higher blood pressure and AST, ALT, GGT, LDH, CPK, Creatinine, Uric acid, total cholesterol, TG, and LDL levels than other groups, while having a lower HDL level. In the living habits survey, the Taeeumin group showed the highest proportion of "overeating", and the lowest proportion of "eating slowly". This group had the highest value of quantity of alcohol drinking, highest proportion of hazardous drinkers, and highest smoking rate of the three constitutions. Conclusions : In the results of this study, there were significant differences in the living habits behaviors, and the results of health examination, between the three constitutions. In particular, individuals of the Taeeumin group have a high possibility of getting chronic disease, such as hypertension, diabetes mellitus, hyperlipidemia, and obesity; and need to improve their living habits.

Nelumbo nucifera Gaertner leaf (NNL) has been known that is effective to lowering blood pressure and hyperlipidemic levels. But, its pharmacological actions have not been demonstrated. Therefore, the present research was performed to find the effect of NNL on hyperlipidemic actions in Bio F1B hamster as a model for hyperlipidemia and atherosclerosis. The hyperlipidemic hamster were induced by basal diet containing 10% coconut oil and 0.05% cholesterol with high fat atherogenic diet(HFAD). A control group and treated groups NNL100, 200, 400 mg/kg/day were fed a HFAD, but a normal group was fed a basal diet only. In conclusion, the serum total cholesterol levels were significantly declined on day 40 in F1B hamster given the NNL extracts (200, 400 mh/kg/day) with p<0.05, when compared with a control value of HFAD fed hamsters. The hepatic TC level was significantly lower in NNL 200 and 400 mg/kg/day group than of control hamster on day 40. But, the HDL levels were not changed between control and treated NNL groups. The TG levels of NNL treated groups showed a decrease tendency compare to the control value. In addition, accumulation of fatty level showed a slight decline to NNL treated groups in aortic arch.

The antioxidative effects of solvent fractions of kimchi on LDL oxidatiojn in vitro as well as hypolipidemic effects of these fractions in rabbit fed atherogenic diet were studied. Methanol extract of deffated kimchi was fractionated sequentially with dichloromethane, ethylacetate, butanol and water. All solvent fractions of kimchi inhibited Cu2+-induced LDL oxidation. Among these fractions, the dicholoromethane fraction at the concentration of 25$\mu\textrm{g}$/mL showed the highest antioxidant effects against LDL oxidation in the aspect of inhibiting TBARS production by 28.03% or prolonged lag phase duration 2-fold compared to those of control. Based on the results from in vitro study, New Zealand White Rabbits grouped six each were fed for 8 weeks either basal diet containing 1% cholesterol or experimental diet containing dichloromethane, ethylacetate or water fraciton added to the basal diet. The amount of solvent fraction of kimchi added to the experimental diet was equivalent to 5% of freeze-dried kimchi. The hypolipidemic effects was observed from all experimental gropus, especially from dichloromethane fraction added group. The plasma and LDL cholesterol levels of this group were decreased by 49% and 47%, respectively while that of HDL increased by 91% compared to those of control. The calculated atherogenic index for the dichloromethane group was the lowest among groups. However, TG lowering effect of experimental group was not observed since solbent fraction of kimchi was used instead of freeze-dried kimchi. The TBARS concentration of LDL isolated from rabbit fed dichloromethane fraction was decreased 21% than that of control. These results indicate that active principles responsible for inhibiting LDL oxidation and lowering plasma cholesterol may present abundantly in dichloromethane fraction of kimchi.

Chaga mushroom and Cheonggukjang have been used in alternative medicine. In this study, we determined the anti-obesity effects of fermented Chaga-Cheonggukjang (FCC), an extract prepared by secondary fermentation of a mixture of Cheonggukjang and Chaga by Lactobacillus acidophilus on highfat diet (HFD)-induced mice. Male ICR mice were fed a normal diet or HFD in the presence or absence of 3% and 5% FCC (FCC3 and FCC5). After 3 months, the mice were sacrificed, and serum and tissue samples were examined. Body weight and epididymal fat pad (EFP) weight were significantly lowered in FCC3 and FCC5 groups compared to those in the HFD control group. FCC supplementation suppressed serum triglyceride (TG) and increased serum HDL levels. Serum GOT, GPT, leptin levels and hepatic COX-2 mRNA expression were significantly higher in the HFD groups, and these increases were significantly attenuated by FCC supplementation. FCC suppressed body weight and EFP weight gain, as well as inflammatory responses in the liver in HFD-fed mice. Thus, FCC supplementation may have protective effects for obesity-related disease.
