Objectives: This study was designed to evaluate the efficacy of Changbudodam-tang on obesity by using high-fat diet rats. Methods: Rats were divided into five groups. Normal group: Normal diet, Control group: High-fat diet, Positive control group: High-fat diet+Dietamin 4 mg/kg/day, Changbudodam-tang-Low group: High-fat diet+Changbudodam-tang 250 mg/kg/day, Changbudodam-tang-High group: High-fat diet+Changbudodam-tang 500 mg/kg/day. Weight, food intake were measured every week. After 7 weeks, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol, Triglyceride, free fatty acid, aspartate aminotransferase, alanine aminotransferase, complete blood count were measured and messenger ribonucleic acid expression of adiponectin, peroxisome proliferator-activated receptor-γ, leptin were observed using Reverse transcription polymerase chain reaction of liver cells. Results: There was no difference in food intake between groups. Body weight tended to decrease compared with the Control group, but it wasn't statistically meaningfull. The total cholesterol, low density lipoprotein-cholesterol, Triglyceride, free fatty acid tended to decrease compared with the Control group. High density lipoprotein-cholesterol tended to decrease compared with the Control group, but it wasn't statistically meaningfull. White blood cell, red blood cell, hemoglobin, platelet, aspartate aminotransferase, alanine aminotransferase were not affected by Changbudodam-tang. The messenger ribonucleic acid expression of Adiponectin, peroxisome proliferator-activated receptor-γ, leptin, which are involved in the differentiation of adipocytes, was decreased compared with the Control group. Conclusions: Based on the results above, it is suggested that Changbudodam-tang can be applied to improving serum lipid levels in obese patients caused by high fat diets.

The effects of phaseolus vulgaris extracts on serum lipid concentrations were evaluated in rats. Forty-two male Sprague-Dawley rats weighing $100{\pm}10\;g$ were divided into six groups and fed high fat diets for four weeks. Experimental groups were administered with following diets; basal fat diet(control) and basal and high fat diets with 1% cholesterol and phaseolus vulgaris extract(40 mg/kg, 400 mg/kg and 4000 mg/kg). The concentrations of serum triglyceride in rats fed the phaseolus vulgaris extract, high fat, 1% cholesterol, and PVHC-40, -400, -4000 mg/kg were lower than those in other groups. The concentrations of total cholesterol in the PVHC-40, -400, -4000 mg/kg groups were lower than those in fat diet groups. The concentrations of HDL-cholesterol in serum of the PVHC-40, -400, 4000 mg/kg groups were significantly higer than those of other groups. The levels of LDL-cholesterol in serum of the PVHC-40, -400, -4000 mg/kg groups were tended to be lower than those of other groups. These results suggest that phaseolus vulgaris extract may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

This study was conducted to investigate the effects of Oenanthe javanica and Allium tuberosum powder on lipid metabolism in rats fed high fat·high cholesterol diet. Experimental rats were divided into five groups which were composed of normal diet group (N), high fat·high cholesterol diet group (HF), high fat·high cholesterol diet with 5% Oenanthe javanica powder diet group (OP), high fat·high cholesterol diet with 5% Allium tuberosum powder diet group (AP) and high fat·high cholesterol diet with 2.5% Oenanthe javanica and Allium tuberosum powder diet group (OAP). The serum TG content of the HF group was significantly increased compared to the N group, but that of the OAP group was significantly decreased. Serum HDL-cholesterol contents of the OAP group was significantly increased compared to the HF group. The serum total cholesterol, LDL-cholesterol and AI of the HF group were increased compared to the N group and especially the LDL-cholesterol of OP and OAP groups were significantly decreased compared to the HF group. The liver TG and total cholesterol contents of the HF group were significantly increased compared to the N group, while TG contents of the OAP group was significantly decreased compared to the HF group. Fecal total lipid and total cholesterol of OP, AP and OAP groups were significantly increased compared to the HF group. These results suggest that supplementation of Oenanthe javanica and Allium tuberosum may have a pronounced impact on markers of lipid metabolism in serum and liver of rats fed high fat·high cholesterol diets.

This study was performed to observe the effects of dietary fat levels and sources on lipids contents and cellularities of liver, brain, and adipose tissue of early weaned rats. Male Sprague-Dawley rats were prematurely weaned from postnatal 17th day with the experimental diets differ in fat levels : low(5%), medium(10%), high(20%) and fat sources : butter, soybean oil, butter＋ soybean oil. On the postnatal 29th day, contents of total lipid, triglyceride, cholesterol and phospholipid of serum, liver, brain and adipose tissue were determined, and DNA was determined to assess the cell growth. Rats early weaned fed high fat diet showed lower total lipid and triglyceride levels in serum and liver than those fed medium or low fat diet Rats early weaned fed high fat diet had adipocytes of fewer number, but larger size than those of rats fed low or medium fat diets. Rats early weaned fed soybean oil diet had more adipocytes thu those fed butter diet. Rats normally weaned to commercial chow diet showed lower total lipid, triglyceride, and cholesterol levels in serum and liver, had fewer adipocytes than all early weaned rats except for rats fed high fat-butter diet. These results suggest that high fat-butter diet is ideal weaning diet at early weaning.

Objectives : Effects of Rhizoma Alismatis extract on lipid composition and TBARS (thiobarbituric acid reactive substances) formation were investigated in rat fed high fat diet. Methods : Seventy male Sprague-Dawley rats were used in these experiments and housed with food and water ad libitum and Twenty rats were selected healthy over 400g body weight and fed high fat diet for 8 weeks. Rhizoma Alismatis extract was administerd at dose 100mg/kg/day, 200mg/kg/day and 300mg/kg/day p.o. for 4 weeks. Then Triglyceride, Total cholesterol, HDL-cholesterol, LDL-cholesterol, TBARS concentration and ALT(Alanine Aminotransferase), AST(aspatate transaminase) activities were determined. Results : Plasma total LDL-cholesterol showed a tendancy to decrease in all treated group(P<0.05), however plasma HDL-cholesterol, total cholesterol, triglyceride showed no significantly different. Rhizoma Alismatis extract feedings resulted in a decrease in plasma TBARS(p<0.05) concentration and AST, ALT activites but contents of TBARS in liver showed no significantly different among all the treatments. Conclusions : Reviewing these experimental results, it appears that Rhizoma Alismatis extract was effective for inhibiting lipid peroxidation and decreasing LDL-cholesterol concentration.

BACKGROUND/OBJECTIVES: Changes in nutritional status during gestation and lactation have detrimental effects on offspring metabolism. Several animal studies have shown that maternal high-fat diet (HFD) can predispose the offspring to development of obesity and metabolic diseases, however the mechanisms underlying these transgenerational effects are poorly understood. Therefore, we examined the effect of maternal HFD consumption on metabolic phenotype and hepatic expression of involved genes in dams to determine whether any of these parameters were associated with the metabolic outcomes in the offspring. MATERIALS/METHODS: Female C57BL/6 mice were fed a low-fat diet (LFD: 10% calories from fat) or a high-fat diet (HFD: 45% calories from fat) for three weeks before mating, and during pregnancy and lactation. Dams and their male offspring were studied at weaning. RESULTS: Dams fed an HFD had significantly higher body and adipose tissue weights and higher serum triglyceride and cholesterol levels than dams fed an LFD. Hepatic lipid levels and mRNA levels of genes involved in lipid metabolism, including $LXR{\alpha}$, SREBP-2, FXR, LDLR, and ABCG8 were significantly changed by maternal HFD intake. Significantly lower total liver DNA and protein contents were observed in dams fed an HFD, implicating the disturbed liver adaptation in the pregnancy-related metabolic demand. HFD feeding also induced significant oxidative stress in serum and liver of dams. Offspring of dams fed an HFD had significantly higher serum cholesterol levels, which were negatively correlated with liver weights of dams and positively correlated with hepatic lipid peroxide levels in dams. CONCLUSIONS: Maternal HFD consumption induced metabolic dysfunction, including altered liver growth and oxidative stress in dams, which may contribute to the disturbed cholesterol homeostasis in the early life of male mice offspring.

This study aimed to investigate the effects of chromium picolinatec (CrP) supplementation on the glucose and lipid metabolism of rats. Five-week-old male Sprague-Dawley rats were fed a high-fat diet fir 110 days and further treated with CrP or placebos for 6 weeks. The effect of CrP supplementation on body weight, blood glucose, insulin and lipid levels was examined. The results suggested that body weight gain was not significantly different between the control and the CrP supplemented group. Plasma glucose, triglyceride and cholesterol levels in the CrP treated group significantly decreased compared to those of the control group (p < 0.05). The total lipid, triglyceride and cholesterol concentrations in the livers of the CrP treated group significantly decreased compared to those of the control group (p < 0.05). These results indicate that supplementation of chromium picolinate ran reduce triglyceride and glucose concentrations in the blood and total lipid and total cholesterol levels in the liver.

This study was designed to determine whether dietary glutinous barley (GB) affects lipid metabolism in middle-aged rats previously fed a high-fat diet. To induce obesity, 20 male 9-month-old Sprague Dawley rats were raised for 1 month on a diet containing 20%(w/w) lipid. The rats were allocated to 1 of 2 groups of 10 rats each and for the subsequent 2 months were fed an 8%(w/w) lipid diet containing well-milled rice (WMR) or GB powder. Rats fed the GB diet had significantly lower concentrations of plasma triglyceride, plasma total cholesterol, and liver cholesterol than rats fed the WMR diet. Fecal excretions of triglyceride and bile acids were significantly greater for the GB group than for the WMR group. In conclusion, dietary GB has positive effects on lipid metabolism: it decreases plasma cholesterol concentration by increasing fecal excretion of bile acids.

Objectives : In this research, it was investigate that had effects on acupuncture techniques of $HT_{8}$(Shaofu) and $LR_{2}$(Xingjian) acupoints in high fat rats. We recorded data of weight gain, food intake, food efficiency, total cholesterol, triglyceride, AST, ALT, r-GTP, total bilirubin on rats fed high fat diet for 10 weeks. Methods : We divided experimental groups into four. Group of high-fat diet feeding and no treatment was control, group of high-fat diet feeding and acupuncture at $HT_{8}{\cdot}LR_{2}$ was Acu-1, group of high-fat diet feeding and acupuncture at $HT_{8}{\cdot}LR_{2}$ and rotated counter-clockwise 36times was Acu-2, high-fat diet feeding and acupuncture at $HT_{8}$(body direction)${\cdot}LR_{2}$(lower limb direction) and rotated counter-clockwise 36times was Acu-3. Results : In Acu-3 group, body weight on 2 weeks after starting acupuncture, food efficiency and the level of serum total cholesterol were decreased, and the level of HDL-cholesterol was increased. In Acu-1 group, the level of triglyceride was increased but ALT was decreased. Conclusions : These results suggest that treatment of acupuncture at $HT_{8}$(body direction)${\cdot}LR_{2}$(lower limb direction) and rotated counter-clockwise 36times may be having the influence on high fat by controlling the level of serum total cholesterol and HDL-cholesterol.

Obesity is an epidemic disease characterized by an increased inflammatory state and chronic oxidative stress with high levels of pro-inflammatory cytokines and lipid peroxidation. Moreover, obesity alters cholesterol metabolism with increases in low-density lipoprotein (LDL) cholesterols and triglycerides and decreases in high-density lipoprotein (HDL) cholesterols. It has been shown that mulberry leaf and fruit ameliorated hyperglycemic and hyperlipidemic conditions in obese and diabetic subjects. We hypothesized that supplementation with mulberry leaf combined with mulberry fruit (MLFE) ameliorate cholesterol transfer proteins accompanied by reduction of oxidative stress in the high fat diet induced obesity. Mice were fed control diet (CON) or high fat diet (HF) for 9 weeks. After obesity was induced, the mice were administered either the HF or the HF with combination of equal amount of mulberry leaf and fruit extract (MLFE) at 500mg/kg/day by gavage for 12 weeks. MLFE treatment ameliorated HF induced oxidative stress demonstrated by 4-hydroxynonenal (4-HNE) and modulated the expression of 2 key proteins involved in cholesterol transfer such as scavenger receptor class B type 1 (SR-B1) and ATP-binding cassette transporter A1 (ABCA1) in the HF treated animals. This effect was mainly noted in liver tissue rather than in cutaneous tissue. Collectively, this study demonstrated that MLFE treatment has beneficial effects on the modulation of high fat diet-induced oxidative stress and on the regulation of cholesterol transporters. These results suggest that MLFE might be a beneficial substance for conventional therapies to treat obesity and its complications.
