This study investigated black garlic and mugwort extracts have anti-stress activity. The antioxidant activities of extracts from black garlic (BEP), mugwort (MEP), and three mixtures (MPA, 95:5; MPB, 90:10; MPC, 85:15, w/w% for BEP and MEP, respectively) were tested in vitro. DPPH and ABTS radical scavenging activities for the mixtures (MPA, MPB and MPC) were significantly elevated in a dose-dependent manner by the amount of mugwort extract. A restraint stress was imposed on six groups of Sprague-Dawley rats supplemented with an AIN-93 diet (RSC) or one of five kinds of hot water extract drinks containing (black garlic, RS1; mugwort, RS2; and mixtures of black garlic : mugwort at 95:5, RS3; 90:10, RS4, and a mixture of black garlic : mugwort : apple extract : xylitol=90.25:4.75:2:3, RS5; v/v%) for 4 weeks. The normal group was fed with the AIN-93 diet and not exposed to restraint stress. Food intake was higher in the group fed with garlic extract (RS1), while the body weight gain and food efficiency ratio did not significantly change. The total serum cholesterol content in the RS1 and RS2 groups was significantly lower than the RSC group (control), and the RS5 group was not significantly different compared to the RS3 group. The serum triglyceride content was significantly higher RS3~RS5 groups than RS1 and RS2 groups. In terms of HDL-C and LDL-C contents, AI and CRF in the serum were not significantly different between RS3 and RS5 groups. AST and ALP activities of RS1~RS5 groups were significantly lower than the RSC group. The liver total lipid and cholesterol contents of RS1~RS5 groups were significantly lower than RSC group, and triglyceride content was significantly lower in the RS1 group. Glycogen in the liver tissue was significantly higher in the RS2 and RS3 group compared to the RSC group. These results show that the intake of a mixture of black garlic and mugwort extracts may be effective in the alleviation of hyperlipidemia caused by restraint stress.

This study evaluated the effects of Rubus coreanus Miq. oil on the plasma lipid profile of high fat diet (HFD)-induced obese mice. Animals were randomly divided into 4 groups (n=10). After completion of the 5-week experimental period, we measured bodyweight gain, food intake, adipose tissue mass, and plasma lipid profile. We also analyzed the activities of carnitine and superoxide dismutase (SOD) involved in ${\beta}$-oxidation and antioxidation, respectively. Our results show that HFD-induced weight gain in animals in the R. coreanus Miq. oil diet group (RCO) and corn oil diet group (CO) was significantly lower compared to animals in the HFD group; RCO supplementation had a more noticeable effect than CO. Visceral and back fat weights were lower in the RCO and CO groups while plasma HDL cholesterol (HDL-C) and HDL-C per total cholesterol [HDL-C/TC (%)] ratio were significantly higher in the RCO group. The contents of acid-soluble acylcarnitine and total carnitine as well as SOD activation were significantly higher in the RCO group, but no significant difference was observed between the RCO and CO groups. In conclusion, RCO effectively averted elevation of total body weight and fat weight in HFD-induced obese mice and promoted increased HDL-C. Therefore, R. coreanus Miq. oil might play an anti-obesity role in obese people and could be used as an effective oil supplement.

This study was carried out to investigate the effects of red ginseng product and combined exercise on the changes of blood lipids(total cholesterol, high density lipoprotein, low density lipoprotein, triglyceride) and body composition (weight, % body fat) of obese women in their twenties. The experiments were performed with 21 women who had up to 30% body fat. They were randomly assigned into three groups [CON : control group (n=7), EXPI : red ginseng product group (n=7), EXP2 red ginseng product + exercise group (n=7)]. EXPI group and EXP2 group took red ginseng product for 12 weeks, and especially EXP2 group performed combined three-times-a-week exercise during the experiments period, too. The blood of each group was also sampled for three times (before experiments, after 8 weeks, after 12 weeks) to know the changes of blood lipid profile. Weight and %body fat were measured by body composition analyser. After 12 weeks, weight increased in CON group, but decreased in EXP1 and EXP2 group significantly. %body fat significantly decreased in EXP1 and EXP2 group, but not in CON group. When other two groups steadily increased in TC, EXP2 group constantly decreased, although there was no significant difference. After 12 weeks, while CON group and EXP2 group decreased within narrow limits in HDL-C, EXPI group was showing a rising tendency. But couldn't find any significant difference. Between the 8th and the 12th week, CON group and EXPI group were showing a rising tendency in LDL-C. But there was little change in EXP2 group. The results of ANOVA didn't show any significant difference. In TG, CON group and EXP2 group had little change. On the other hand, EXPI group steadily decreased. But there was no significant difference. In conclusion, with the 12-week experiments, weight and %body tat significantly decreased by red ginseng product and combined exercise which could derive profitable changes from blood lipids-especially total cholesterol, HDL-C, TG.

Among patients who are receiving treatments at an oriental medical hospital for various symptoms and diseases, patients whose main disease is accompanied by metabolic syndrome with abnormal liver function. This research was performed in order to observe the progression of changes in the liver function and serum lipid profile after the oriental medical treatments to patients who have been receiving oriental medical treatment for various other diseases and have been diagnosed as having metabolic syndrome at their first visit to the hospital based on NCEP ATP III diagnosis criteria and WHO Asia Pacific region criteria. Total number of subject patients were 39cases(mean age:55.58${\pm}$2.09 years) which had 20 male and 19 female. For the references for hepatic enzyme levels and blood lipid profile were measured in before treatment and four times after treatments(every 2.31${\pm}$06.17 weeks). Serum AST was 48.86${\pm}$7.46 IU/L before oriental medical treatment. After the treatment, 40.63${\pm}$4.69, 43.12${\pm}$5.46, 37.82${\pm}$4.52 IU/L were measured where although the level decreased to the normal level compared to pre-treatment, the value was not significant statistically(P>0.05). ALT was 66.26${\pm}$11.01 IU/L before oriental medical treatment. After the treatment 62.10${\pm}$8.20, 61.10${\pm}$8.76, 43.79${\pm}$5.68 were measured where although the level decreased, abnormally high level was maintained. The last result was significant statistically(P<0.05) compared to pre-treatment. ALP was 193.06${\pm}$14.20 IU/L before oriental medical treatment. After the treatment, 176.80${\pm}$6.48, 177.46${\pm}$11.81, 162.41${\pm}$9.06 where although compared to pre-treatment the last result was significant statistically(P<0.05), the change was within the normal range. ${\gamma}$-GGT was 87.83${\pm}$12.59 IU/L before oriental medical treatment. After the treatment, progressively near normal level was achieved with 118.73${\pm}$46.45, 85.03${\pm}$17.12, 70.64${\pm}$10.93 and the last result was statistically significant compared to pre-treatment (P<0.05). Blood triglyceride was 217.63${\pm}$32.18 mg/dL before oriental medical treatment. After treatment 215.09${\pm}$22.18, 189.93${\pm}$22.44, 191.22${\pm}$18.51 where abnormal values continued even after treatment although results was not statistically significant compared to pre-treatment(P>0.05). Total-cholesterol was 197.28${\pm}$9.24 mg/dL before oriental medical treatment, after treatment 201.55${\pm}$11.13, 186.87${\pm}$8.77 and 186.68${\pm}$7.61 were measured that results were not statistically significant compared to pre-treatment(P>0.05). HDL-cholesterol was 41.88${\pm}$2.38 mg/dL before oriental medical treatment, after treatment 48.75${\pm}$4.22, 44.10${\pm}$1.91, 48.00${\pm}$2.06 the results were not statistically significant compared to pre-treatment(P>0.05). LDL-cholesterol was 111.66${\pm}$13.08 mg/dL before oriental medical treatment, after treatment 109.94${\pm}$10.18, 101.79${\pm}$8.63, 104.00${\pm}$6.98 the results were not statistically significant compared to pre-treatment(P>0.05). With such results, even if common oriental medical treatments were given to metabolic syndrome patients with abnormal liver function, the liver function was confirmed not to be aggravated, and the concentration of lipids in the blood was confirmed not to be affected in most patients.

Objectives: The analysis of heart rate variability (HRV) is a useful non-invasive tool to investigate the autonomic nerve function. Previous studies on the relationship between HRV and depression have been reported controversial results. Similarly, the correlation between the serum lipids and depression is debatable. The purpose of this study is to examine the relationship between heart rate variability, lipid profile and depression. Methods: A total of 42 patients with major depressive disorder (MDD) and 32 age and sex-matched normal subjects who had no previous history of major medical and mental illnesses were recruited for this study. A structured-interview was used to assess the general characteristics and psychiatric illness. HRV measures were assessed by time-domain and frequency-domain analyses. Psychological symptoms were measured using the Hamilton rating scale for anxiety (HAM-A), Hamilton rating scale for depression (HAM-D). In addition, the evaluation for lipid profile was performed by blood test. Results: In serum lipid profile test, MDD group showed higher cholesterol ($197.68{\pm}42.94$ mg/dL vs. $176.85{\pm}34.68$ mg/dL, p=0.044), TG ($139.45{\pm}92.54$ mg/dL vs. $91.4{\pm}65.68$ mg/dL, p=0.018), LDL ($130.03{\pm}33.18$ vs. $106.62{\pm}27.08$, p=0.004) level than normal control group. In HRV time domain analyses, the standard deviation of the NN interval (SDNN) was decreased in MDD group than normal control group, but was not significant ($32.82{\pm}14.33$ ms vs. $40.36{\pm}21.40$ms, p=0.078). ApEn (Approximate Entrophy) was significantly increased in MDD group than normal control group ($1.13{\pm}0.11$ vs. $0.91{\pm}0.18$, p<0.001). ApEn was correlated with LDL level (r=0.277, p=0.028), HAM-D scores (r=0.534, p<0.001) and HAM-A scores (r=0.470, p<0.001). Conclusions: MDD patients showed increased ApEn, one of the HRV measurement. And this ApEn was correlated with LDL, HAM-D and HAM-A scores. In this study, the analysis of ApEn would be a useful test of MDD.

The purpose of this study was to compare the nutrient intakes, blood pressure, and biochemical values and lipid profile in blood according to smoking status. Subjects were recruited from Korean adult men, which included non-smoker (n=47), smoker (n=58), and ex- smoker (n=44) . Anthropometrical measurement, blood pressure measurement, dietary intake assessment using 24-hour recall method, and blood collection and analysis were conducted. The average age, height, weight, and BMI of the subject were 54.7 years, 165.8 cm, 67.3 kg, and $24.5\;kg/m^2 $, respectively. There was no significant difference in general characteristics among three groups. The mean daily intakes of energy and protein were 1740.9 kcal and 69.6 g. The daily folate intake of the smoker was significantly lower than that of the non- smoker or ex-smoker. However, cholesterol intake of the smoker was significantly higher than two groups. The daily total food intake was 1250.0 g for non-smoker, 1180.1 g for smoker, and 1237.5 g for ex-smoker. The mushrooms intake in the smoker was significantly lower than that in the ex - smoker. However, eggs intake of the smoker was significantly higher than two groups. The RBC count and serum GOT/GPT of the subjects were $4598.2\times1000/mm^3$ and 27.3/27.3 U/L. The WBC count, hematocrit and hemoglobin of the smoker were significantly higher than those of the non-smoker and ex-smoker. Blood pressure and serum lipids of the subjects were 128.3/75.5 mmHg for SBP/DBP, 180.2 mg/dL for total cholesterol, 160.8 mg/dL for triglyceride, 41.5 mg/dL for HDL-cholesterol, 106.5 mg/dL for LDL-cholesterol, and 3.5 for atherogenic index. Especially serum triglyceride of smoker was significantly higher than that of non-smoker. The above results revealed that some nutrient intakes, such as folate and cholesterol, and hematological findings, and serum triglyceride of the smoker were different from non-smoker. However, these differences were recovered to non-smoking status by prohibition of smoking. Therefore, in order to stop smoking, the effect of smoking on nutritional and health status should be informed to smoker and more systematic study should be conducted.

Three kinds of dietary composites-R+T, R+F, and R+TF-were combined in green tea (T), dietary fiber (F), and green tea dietary fiber mixture (TF) to red garlic extract (RG), respectively. The effects of their diets on anti-obesity were investigated $in$ $vitro$ and $in$ $vitro$ in obese rats induced high fat-cholesterol. In $in$ $vivo$ rats, the total phenolic content of the R+T and R+TF was 1.9~2.0 times higher, and their total cholesterol adsorption was 9.5~11.5 times higher than that of RG. $In$ $vivo$, male Sprague-Dawley rats were divided into 6 groups (Normal, HFC, HRG, HR+T, HR+F and HR+TF). Afterwards, the diets of the HRG, HR+T, HR+F, and HR+TF groups were supplemented with 1% of RG and its dietary composites (R+T, R+F, and R+TF) for 4 weeks, respectively. The final body weight of the HRG, HR+T, HR+F, and HR+TF groups decreased significantly compared to the group fed high fat-cholesterol (HFC), but the food efficiency ratio was not significantly different from the HFC group. The liver weight of the HFC group doubled compared to the normal group, whereas that of HR+T and HR+TF groups decreased significantly. The weight of visceral and epididymal fat decreased significantly in the groups fed the composites compared to the HFC group. The obesity index of HR+TF group decreased significantly only when compared to the HFC group. The serum lipid profile such as total lipids, cholesterol, triglyceride, LDL- and VLDL-cholesterol, as well as the atherogenic index and cardiac risk factors decreased drastically in all experimental groups compared to the HFC group, and the levels of HR+T, HR+F and HR+TF groups were a similar trend. GPT activity was not significantly different among the groups fed the composites, and it decreased significantly in the HRG group. The content of the lipid peroxide level decreased significantly in the HRG group and in the groups fed the composites, compared to the HFC group. Serum antioxidant activity was the highest in the HR+T group. We suggest that the hypolipidemic and anti-obesity effect of the RG composites, achieved by mixing green tea extract and/or dietary fiber, was due to their total phenolic content and total cholesterol adsorption effect.

This study was conducted to evaluate the effect of whole egg supplementation on the blood lipid profiles and cholesterol levels of C57BL/6 mice. Sixty-six mice were divided into two groups: normal-diet supplemented and high-cholesterol diet supplemented. Lyophilized whole egg powder was mixed with the two diets at 2 and 10%: normal diet only, normal diet with 2 and 10% whole egg powder, high cholesterol diet only, high cholesterol diet with 2 and 10% whole egg powder. The mixed diets were fed for 5 wk and feeding condition (body weight change, feed intake, and feed efficiency ratio (FER)), blood lipid profiles (total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein cholesterol, hepatic and fecal lipids (TG, TC)), and fecal bile acids were determined. No significant differences were found in body weight gain or FER after whole egg supplementation in both the normal and high-cholesterol diet fed groups. In the normal-diet fed mice, HDL-C increased significantly in the 2 and 10% whole-egg powder groups. In the high-cholesterol diet fed mice, administering 10% egg powder increased the atherogenic index compared to the control. Furthermore, administration of whole egg powder increased fecal bile acids dose dependently (p<0.05). These results indicate that administering 2% hen whole egg powder did not affect blood lipid profiles and was more beneficial for health by increasing HDL-C and aiding in the excretion of cholesterol by fecal bile acids than those in the control.

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.

Objective: This study was conducted to evaluate the effects of diets containing different wet rice distillers' by-product (RDP) levels on growth performance, nutrient digestibility, blood profiles and gut microbiome of weaned piglets. Methods: A total of 48 weaned castrated male crossbred pigs, initial body weight 7.54±0.97 kg, and age about 4 wks, were used in this experiment. The piglets were randomly allocated into three iso-nitrogenous diet groups that were fed either a control diet, a diet with 15% RDP, or a diet with 30% RDP for a total of 35 days. Chromium oxide was used for apparent digestibility measurements. On d 14 and d 35, half of the piglets were randomly selected for hemato-biochemical and gut microbiota evaluations. Results: Increasing inclusion levels of RDP tended to linearly increase (p≤0.07) average daily gain on d 14 and d 35, and decreased (p = 0.08) feed conversion ratio on d 35. Empty stomach weight increased (p = 0.03) on d 35 while digestibility of diet components decreased. Serum globulin concentration decreased on d 14 (p = 0.003) and red blood cell count tended to decrease (p = 0.06) on d 35, parallel to increase RDP levels. Gene amplicon profiling of 16S rRNA revealed that the colonic microbiota composition of weaned pigs changed by inclusion of RDP over the period. On d 14, decreased proportions of Lachnospiraceae_ge, Ruminococcaceae_ge, Ruminococcaceae_UCG-005, and Bacteroidales_ge, and increased proportions of Prevotellaceae_ge, Prevotella_2, and Prevotella_9 were found with inclusion of RDP, whereas opposite effect was found on d 35. Additionally, the proportion of Lachnospiraceae_ge, Ruminococcaceae_ge, Ruminococcaceae_UCG-005, and Bacteroidales_ge in RDP diets decreased over periods in control diet but increased largely in diet with 30% RDP. Conclusion: These results indicate that RDP in a favorable way modulate gastrointestinal microbiota composition and improve piglet performance despite a negative impact on digestibility of lipids and gross energy.
