This study was undertaken to evaluate the effect of bacteria-derived $\beta$-glucan fiber on serum lipids, adiposity and uncoupling protein (UCP) expression in rats. In order to induce obesity, Sprague-Dawley weanling male rats were allowed free access to AIN-76A diet until 4 weeks of age, and fed high-fat diet (beef tallow, $40\%$ of calories as fat) for 6 weeks until 10 weeks of age. Rats were then fed with $0\%$ thigh- fat control group), $1\%$, or $5\%$ bacterial ~-glucan supplemented high-fat diets (w/w) for another 6 weeks. For comparison, normal control group was fed with AIN-76 diet $11.7\%$ fat). Supplementation with bacterial $\beta$-glucan resulted in a significant reduction of high-fat-induced white fat (i.e., visceral and peritoneal fat) development, adipocyte hypertrophy, and development of hyperinsulinemia and hyperleptinemia. Serum triglyceride, total cholesterol, and free fatty acid levels were greatly reduced, but, HDL-cholesterol concentrations were increased by bacterial $\beta$-glucan supplementation. Serum leptin level was lower in the $\beta$-glucan groups than in the high-fat group. The expression of UCPs (UCP1, UCP2, and UCP3) in brown adipose tissue (BAT) were significantly increased by $5\%$ bacterial $\beta$-glucan-containing diet. This study suggests that the anti-obesity effect of $5\%$ bacterial $\beta$-glucan is attributed to upregulation of UCPs and inefficient energy utilization.

This study investigated the anti-obesity effects of Eriobotrya japonica leaves extract (EJE) in a high-fat diet-induced obese mice model. For the analysis, 40 mice were randomly divided into five groups: normal diet (ND), high-fat diet group (HD), high-fat diet containing EJE 100 mg/kg b.w. (EJE-L), 500 mg/kg b.w. (EJE-H), and Garcinia cambogia extract 100 mg/kg b.w. in each AIN 93G supplement for 8 weeks as positive control. During the study period, food intake and body weight were measured separately. Body weight, serum triglyceride level, and total cholesterol levels of the EJE group were significantly lower than those of the HD and ND. Moreover, mice fed an EJE-containing high-fat diet showed decreased leptin levels compared with high-fat diet-induced obese mice. These results suggest that EJE has potential as an anti-obesity agent by reducing body weight and improving levels of triglycerides, total cholesterol, low density lipoprotein-cholesterol, and leptin in serum.

This study was performed to observe how soy protein and calcium in rats fed unsaturated fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues male Sprague-Dawley rats weighing approximately 220g were fed four purified diets which contained 18% (w/w) corn oil, 1% (w/w) cholesterol, two sources of protein : casein or isolated soy protein (ISP) and two levels of dietary calcium : 0.1% or 1.0%, first for four weeks (Expt. 1) and second for eight weeks (Expt. 2). The contents of total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding, the serum lipid and cholesterol concentration was not significantly different among the groups. After eight weeks feeding, these concentrations were significantly lower in ISP-High calcium group. The serum lipid concentration was influenced by dietary protein sources and calcium levels. These results indicated that the hypolipidemic effects of soy protein and high calcium intake were partly due to decrease in lipid absorption and these effects were not detected at 4 weeks feeding but 8 weeks feeding.

This study was conducted to investigate the effects of powdered young barley leaf and its water extract on body weight and lipid metabolism in high-fat fed mice. Male mice were divided into normal group, high-fat (HF) group, high-fat group supplemented with powdered young barley leaf (HF-YBL) and high-fat group supplemented with water extract of the powdered young barley leaf (HF-WYBL). The powdered young barley leaf or its water extract was added to a standard diet based on 1% dried young barley leaf (1 g YBL/100 diet and 0.28 g WYBL/100 g diet) for 8 weeks. Supplementation of YBL and WYBL significantly reduced body weight and epididymal adipose tissue weight in high-fat fed mice. Food intake and daily energy intake were significantly lower in the YBL group than in the HF group. After 8 weeks, plasma triglyceride and cholesterol concentrations were significantly higher in the HF group than in the Normal group; however, both YBL and WYBL significantly lowered those of the high-fat fed mice. The ratio of HDL-cholesterol/total cholesterol of the YBL and WYBL groups were significantly elevated compared to that of HF group. Both YBL and WYBL significantly increased fecal excretion of triglyceride in high-fat fed mice, whereas they did not affect fecal cholesterol concentration. The triglyceride levels of liver, adipose tissue and heart were significantly lower in the YBL and WYBL groups than in the HF group. Supplementation of WYBL also lowered the kidney triglyceride and heart cholesterol concentrations compared to those of HF group. Hepatic lipid regulating enzyme activities, fatty acid synthase, HMG-CoA reductase and acyl-coenzyme A: cholesterol acyltransferase, were significantly lower in the YBL and WYBL groups than in the HF group. Accordingly, these results suggest that YBL and WYBL improve plasma and organ lipid levels partly by increasing fecal lipid excretion and inhibiting fatty acid and cholesterol biosynthesis in the liver.

Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (<50 mg/dL, n=20), medium HDL-cholesterol (50 $\leq$, < 60 mg/dL, n=39) high serum HDL-cholesterol groups (60 $\leq$ mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate: protein: fat was 57:15:28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.

Objectives : This study was aimed to investigate the effect of ACLL extract (Artemisia capillaris Thunb, Curcuma longa L, Lycium chinense, Ligustrum lucidum Aiton complex extract) in a dyslipidemia animal model induced by a high-fat diet. Methods : ACLL extracts was administered at 200 mg/kg, and 400 mg/kg to Apoe mice, where arthritis was induced by high cholesterol diet. After mice were treated with GO for 4 weeks, we measured AST, ALT, BUN and lipid levels (total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride), atherogenic index(AI) and cardiac risk factor(CRF). Results : Serum AST, ALT, creatinine, BUN levels were not changed by ACLL extract do not show any toxic effects. Also, ACLL extract groups were found to have atherogenic Index and cardiac risk factor as well as lipid metabolism improvement (total cholesterol, LDL cholesterol and triglyceride decrease). Conclusions : We suggest that ACLL extract may have the control effects of Dyslipidemia by improving lipid metabolism.

To examine the cholesterol-towering effects of extruded products made with cassava starch (CS) and blends of cassava starch with either resistant starch (CS-RS) or oat fiber (CS-OF) hamsters were fed with diets containing a high-cholesterol (2%) and high-fat (17%) diet for 20 days. Hamsters fed with a diet containing no cholesterol were used as a control. Total cholesterol (TC) levels in the CS-RS and CS-OF groups were significantly (p>0.05) lower compared to the CS group by 11.5% and 8.5%, respectively. Also, the diets containing fibers decreased the value of low-density lipoproteins plus very low-density lipoproteins fraction by 32.4% (CS-RS diet) and 51.7% (CS-OF), respectively, as compared to the CS diet. Total lipid values were significantly (p<0.05) lower in hamsters fed the CS-RS diet (916 mg/dL) and CS-OF diet (964 mg/dL) as compared to those fed the CS diet (1661 mg/dL). The results obtained in this study suggest that extruded products containing cassava starch blended with either resistant starch or oat fleer, could prevent health problems associated with high levels of cholesterol and hypertriglyceridemia induced by a high cholesterol and fat diet.

Objectives : The present study was conducted to examine whether Cynanchi wilfordii radix (CWR) with or without fermentation has an ameliorative effect on hyperlipidemia in rats.Methods : We analyzed the contents of Conduritol F on Cynanchi wilfordii radix. The experimental animals were divided into six groups; normal diet fed group (N), high cholesterol fed control group (Con), Lovastatin 20 mg/kg (L), CWR-W 300 mg/kg (CWR-W), and CWR-F 300 mg/kg on hyperlipidemia model induced by feeding 1.25% cholesterol. Rats were administrated orally every day for 8 weeks. And lipid profile of serum and weight change were observed.Results : The vehicle displayed a markedly increased body weight and significantly increased liver and epididymal fat weight, however, the administration of CWR improved the body, liver, and epididymal fat weights. All drug treatment reduced significantly the serum level of total cholesterol and LDL-cholesterol elevated by intake of high cholesterol diet. TG displayed a reducing tendency all drug treatment, however, CWR-W decreased significantly. Atherogenic index and cardiac risk factor increased high cholesterol diet fed control group, while the administration of CWR-W and CWR-F decreased significantly. The major index of liver injury such as AST and ALT improved in all drug treatment.Conclusions : These results suggest that CWR extended the effect of lipid enhanced. Therefore CWR with or without fermentation may be useful for therapeutic treatment of clinical conditions associated with hyperlipidemia. Finally, these require more investigations about the action mechanism of CWR in the future.
