In order to determine the effective concentration, 2, 7, and 14 brix black garlic extracts (BGE) were fed to restraint stressed rats and the lipid metabolism was analyzed. The dietary intake of the 14 brix BGE-fed group was $547.64{\pm}13.99$ g/4 weeks and it was significantly higher than that of the control group. The weight of all organs from the all BGE-fed groups showed no significant differences. While BGE concentration increased, BGE-fed groups tend to have low content of blood glucose. It was the lowest in the 14 brix BGE-fed group ($121.32{\pm}3.50$ mg/dl). Total cholesterol content was $54.54{\pm}1.63{\sim}65.84{\pm}2.61$ mg/dl. Total cholesterol content of the 14 brix BGE-fed group was the lowest and, in addition, lower than the normal group. Triglyceride content of serum showed the same tendency. HDL-cholesterol concentrations of the restraint stressed control (RSC) group were significantly higher than those of 7 and 14 brix BGE-fed groups. LDL and VLDL-cholesterol contents showed contrary results. GOT, GTP, and ALP activity of serum were lower when BGE concentration was higher. It is expected that BGE has a liver protective activity. In the liver, total lipids and triglyceride contents were significantly lower in BGE-fed groups than in the ISC group. However, total cholesterol content showed no significant difference between groups. TBARS content in liver of the 2 brix BGE-fed group was not significantly different than control, while 7 and 14 brix BGE-fed groups were lower than control. Glycogen content in the liver was only significantly lower in the 14 brix BGE-fed group than in the RSC group. Findings indicate that feed of BGE over 7 brix contributes to resolving the restraint-stressed rats by improving the lipid metabolism and liver protective activity.

There is a rising trend in obesity due to various factors, including changes in eating habits, lack of exercise, and genetic and psychological factors. Citrus peel has been reported to prevent obesity via antioxidative, antihypertensive, and LDL cholesterol-lowering effects. This study investigated the effects of citrus peel extract fermented with or without Aspergillus oryzae in a mouse model of diet-induced obesity. The animals were divided into four groups: a high-fat diet group (HFD), a normal fat diet (NFD) group, a citrus peel extract (CP) group, and a citrus peel extract fermented with A. oryzae (CPA) group. The citrus peel extract improved lipid metabolism and weight loss in the high-fat diet-induced obese mouse model. As expected, the body weight was higher in the HFD group compared with the NFD, CP, and CPA groups. However, the concentrations of total cholesterol (TG) and triglyceride (TC) in the serum and liver of the CP and CPA groups were lower than in the HFD group. There were no significant differences in the HDL cholesterol concentration among the groups. Taken together, our results suggest that extract of citrus peel biotransformed with A. oryzae had more antiobesity activity than citrus peel not transformed by A. oryzae through the fermentation of metabolites.

Objectives : This study investigated the improvement effects of Pakistani (DF-a) and Chinese Ephedra herba-containing Gangjihwan (DF-b) on obesity in a high fat diet-fed obese mouse model. Methods : Eight-week-old C57BL/6N mice were divided into four groups: a normal lean group given a standard diet, an obese control group given a high fat diet, and DF-a and DF-b groups given a high fat diet with DF-a (80 mg/kg), and DF-b (80 mg/kg), respectively. After 8 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, fat weight and histology were examined. Results : 1. Body weight gain and fat mass were significantly decreased in DF-a and DF-b groups compared with control. The extent of decreases was eminent in DF-a group. 2. Feeding efficiency ratio and circulating leptin concentration were significantly decreased in DF-a and DF-b groups compared with control, whereas circulating adiponectin concentration was increased in DF-a and DF-b groups compared with control. 3. Consistent with their effects on body weight gain and fat mass, circulating concentrations of triglyceride, glucose and insulin were decreased in DF-a and DF-b groups compared with control. 4. The size of adipocytes were decreased by DF-a and DF-b compared with control, whereas the adipocyte number per unit area was increased by them, suggesting that DF-a and DF-b decreased the number of large adipocytes. 5. Consistent with their effects on body weight gain, liver fibrosis was reduced in DF-a and DF-b groups compared with control. Conclusions : In conclusion, these results suggest that DF-a and DF-b not only decrease feeding efficiency ratio, plasma leptin concentration, and blood anti-obesity biomarkers, but also reduce fat mass, contributing to the improvement of obesity. DF-a and DF-b also inhibit liver fibrosis. In addition, these effects were similar between Pakistani Ephedra herba and Chinese Ephedra herba-containing Gangjihwan.

This nutrition survey was carried out twice(Spring and autumn) in Sam Chung-Ri, Song Kwang Myun, Soong Ju-Gun. The food intakes of 92 family members were measured by weighing method. Also 45 adults were examined for anthropometric, blood content and blood pressure. The results abtained were summarized as follows; In vegetable foods, the intake of rice was high, but that of legumina and other cereals was low. In animal foods, the intake of milk and eggs was low, and that of oils and fats was very low. However, the food intake between spring and autumn showed remarkable difference. The average intake of calorie, protein, Ca, Fe and vitamin $B_2$ except vitamin $B_1$ and niacin was below the RDAs. The percentage of carbohydrate, protein and fat for energy was 82.2, 11.6 and 6.2%, respectively. The results of anthropometry of height, weight and chestcircumference showed that both sexes Were below Korean Standards. The concentration of Hb & Hct was normal in both sexes, and the rate of anemia was low. The concentrations of plasma glucose, protein, lipids, and blood pressure were normal in both sexes. In case of male, the correlation between plasma albumin and nutrients intake was significant, but the case of female showed different tendency. In case of male, the correlation between weight, height and plasma protein was also significant but the case of female showed different tendency. The rate of parasite infection was very low $(2.17%{\ldots}3.26%)$
This study was conducted to evaluate the effects of constitutional diets in comparison with general low calorie diets in obese women. The subjects were 52 adult obese women that participated in a calorie restriction diet program (control group, n=16) or a constitutional diet program (experimental group, n=36) for 8 weeks. The subjects in the experimental group were classified as negative (Yin) or positive (Yang) constitution. The obesity management program focused on the calorie restriction diet (300~400 kcal reduction per day) for the control group, whereas, for a constitutional diet without calorie restrictions was allowed for the experimental group. Daily intakes of nutrient and food were assessed using a 24 hr recall method. Body measurements and blood biochemical parameters were measured at baseline and after 8 weeks. After the intervention, weight, body fat, BMI, waist circumference and hip circumference decreased significantly in both the control and experimental group. Energy intake increased from 1,679.6 kcal to 1,810.6 kcal along with significant increase in protein, carbohydrate, fiber, calcium, phosphorus, iron, zinc, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin and vitamin C in the experimental group. Calcium intake increased from 54.0% to 72.4% of DRI in the experimental group. Hemoglobin concentrations were significantly decreased in the control group, but were increased in the experimental group. In addition, blood glucose, serum total cholesterol and triglyceride were significantly decreased in the experimental group. In conclusion, consumption of a constitutional diet without calorie restrictions for 8 weeks was effective for weight reduction with improvement of blood glucose, serum cholesterol and triglyceride.

We determined whether the supplementation of Polygonatum Odoratum (Mill) Druce (POD) extract had a good effect on insulin resistance in peripheral tissues of 90% pancreatectomized (Px) and sham-operated (Sham) male Sprague Dawley rats. Px and Sham rats were divided into two groups; one group daily consumed 0.3 g of POD extracts per 1 ㎏ body weight for two months, and the other group had a placebo. All rats freely consumed a 40% fat diet. At the end of the experiment, a euglycemic hyperinsulinemic (EH) clamp was performed in a fasting, awake, and unstressed state to determine insulin resistance. At EH clamp, body weights were higher in Sham rats than Px rats, and serum glucose levels of baseline were affected by diabetic status and POD administration. Serum insulin concentrations were higher in Sham rats than Px rats, and POD administration decreased them in Sham rats compared to P. Glucose disposal rates in peripheral tissues increased with POD in both Px (n=10) and Sham (n=10) rats. But glycogen deposits in soleus muscle increased with POD administration in Px and Sham rats, and total glycogen synthase activity and fraction velocity were higher in POD groups. Triglyceride contents in quadriceps muscles decreased with POD in Px rats. In conclusions, POD improves insulin resistance by enhancing glucose utilization with increasing glycogen deposit and decreasing triglyceride contents in muscles.

This study was conducted to examine the changes in serum lipid components and blood glucose by krill (Euphausia superba) meal and sodium fluoride (NaF) in rats fed on experimental diets and administered orally to NaF 10 mg for 5 weeks. Body weight of rats decreased as the amount of krill meal diet increased, it was observed the basal diet plus NaF group (BF group) compared to the lower basal diet group (BD group). The serum concentrations of total cholesterol, LDL (low-density lipoprotein) cholesterol, free cholesterol, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the BF group than the 10% krill meal group plus NaF 10 mg (KF10 group) or BD group, the 20% krill meal plus NaF 10 mg group (KF20 group), the 30% krill meal plus NaF 10 mg group (KF30 group). Conversely depending on the content of krill meal for the HDL (high-density lipoprotein) cholesterol level, it showed higher results. The concentration of total protein was no significant difference among the groups (p<0.05). The results indicate that a krill meal diet effectively inhibited increases in lipid elevation and blood glucose level in the sera of rats.

The effects of freeze-dried powder from fresh and black garlic hot water extracts on the lipid metabolism in Sprague-Dawley rats fed a high-cholesterol diet were analyzed. The experimental group was classified into the normal group (NG), the high-fat (HF) and high-cholesterol diet group (CG), the HFC and 1% fresh garlic hot water extract powder-added diet group (FGEG), and the HFC and 1% black garlic hot water extract powder-added diet group (BGEG), respectively. The serum total lipid content was 381.52±7.30 mg/ml and 368.80±4.40 mg/ml in the FGEG and the BGEG, respectively, and was significantly lower than that of the CG. The total cholesterol and triglyceride contents of the FGEG and BGEG were also significantly lower than that of the CG. The high-density lipoprotein (HDL) cholesterol was significantly higher, and the low-density lipoprotein (LDL) and the very low-density lipoprotein (VLDL) cholesterol content was lower in the FGEG and BGEG than in the CG. The serum ALT and AST activities were significantly lower than those of the CG, and especially the BGEG was lower. The total cholesterol content and the triglyceride levels of the liver tissue were 36.0% and 14.3% lower in the BGEG than in the CG, respectively. The thiobarbituric acid reactive substance (TBARS) concentrations in the serum and the liver tissue were higher in the CG than in the FGEG and BGEG, but there was no difference between them. Based on these results, garlic extract powders significantly reduced the lipid profile and increased the antioxidant activity in rats in vivo. The black garlic hot water extract powder was more effective than raw garlic because of the total number of phenolic compounds and browning substances in the black garlic.

This study examined the effects of a soybean sprouts mixture containing 1.5% Hovenia dulcis Thunb. fruit concentrate (SHM) on relieving hangovers and improving liver function in chronically alcohol-treated rats. The ampelopsin and L-asparagine contents in the SHM were 10.52, 35.19 ppm. When chronic alcohol-induced rats were treated with SHM, the body weight increased and the liver weight decreased. The serum alcohol and acetaldehyde concentrations were lowest in the SHM group, and the hepatic ADH and ALDH activities were highest in the SHM group. Chronic alcohol induction increased the activity of liver function indicator enzymes such as ALT, AST, and GGT, but the activity was decreased significantly with the SHM treatment. The triglyceride content in hepatic and serum blood samples was lowest in the SHM group. The serum total cholesterol and LDL cholesterol contents decreased in the SHM group, and the HDL cholesterol content increased. The color of the hepatic observed morphologically in the SHM group was reddish brown, and the size and number of lipid droplets in the hepatic observed pathologically decreased. The hepatic and serum lipid peroxidation content of the SHM group decreased. The hepatic and serum GSH content increased in the SHM group. Therefore, SHM can be a functional food that can help hangovers and improve liver function.

This study examined the effects of Bulnesia sarmienti ethanol extract on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. Sprague Dawley rats were induced with diabetes mellitus by injecting STZ (45 mg/kg) into the tail vein, and were then divided into 5 groups: normal, STZ-control, and three experimental diabetic groups. The rats were fed a basal diet along with B. sarmienti ethanol extract for 8 weeks. According to the results, after 8 weeks of consuming the experimental diets, the body weights and food efficiency ratios of the B. sarmienti ethanol extract-fed groups were not different from those of the control group. However, the concentrations of plasma total-cholesterol, LDL-cholesterol, and triglycerides were significantly lower in the B. sarmienti ethanol extract groups as compared to those of the control group. Although a blood glucose control effect was not observed after the eight weeks of B. sarmienti ethanol extract treatment in this type-l diabetes model, it was discovered that the experimental diets were highly effective at lowering levels of serum lipids, including triglycerides, total-cholesterol, and LDL-cholesterol.
