Objectives : This research was performed to investigate the effects of Rhei Radix et Rhizoma pharmacopuncture at Bi-Su($BL_{20}$) on weight change, food efficiency, concentration of serum lipid, liver function of rats fed high fat diet for 8 weeks. Methods : Subject groups were diveded into normal diet group(Normal), high fat diet group(Control), high fat diet and saline in $BL_{20}$ treated group(Saline), high fat diet and Rhei Radix et Rhizoma pharmacopuncture in $BL_{20}$ treated group(PT-1, 0.008mg/ml/g), high fat diet and Rhei Radix et Rhizoma pharmacopuncture in $BL_{20}$ treated group(PT-2, 0.021mg/ml/g), and high fat diet and Rhei Radix et Rhizoma pharmacopuncture in $BL_{20}$ treated group(PT-3, 0.042mg/ml/g). Pharmacopuncture was bilaterally treated at BL20 every 4 days, totally 14 times in 56 days. We observed the changes of body weight, food efficiency, ALT, AST, r-GTP, total cholesterol, triglyceride, HDL, LDL-cholesterol of each group. Results : 1. Body weight significantly decreased, as compared with the control group, in PT-1 from 2nd week to 8th week, in PT-2 from 4th week to 7th week. 2. Food efficiency decreased, as compared with the control group, in PT-1(0.05${\leq}$p<0.06). 3. HDL-cholesterol increased, as compared with the control group, in PT-1, PT-3, but not significantly. 4. In the changes of ALT, as compared with the control group, only in PT-1 group, the level of serum ALT decreased(0.05${\leq}$p<0.06). 5. As for the changes of r-GTP, as compared with control group, in every subject group, the levels of serum r-GTP significantly decreased. Conclusions : According to the above results, Rhei Radix et Rhizoma pharmacopuncture at $BL_{20}$ can act on body weight, food efficiency and liver function. It also does not seem to be injurious on liver function. To use Rhei Radix et Rhizoma pharmacopuncture for obesity, further studies on its underlying mechanism and optimal dosage might be needed.

Objectives In this study, it was investigated whether Gami-Handayeolso-Tang (HDYST) medication has anti-obesity effects in high fat diet (HFD)-fed obese mice. Methods The experimental animals were divided into five groups-normal diet-fed (ND), high fat diet-fed control (HFD), HFD+HDYST 150, HFD+HDYST 300, and HFD+orlistat as a positive drug. The obese markers such as body weight, diet efficiency ratio, serum levels of total cholesterol, triglyceride, lipid contents, leptin, adiponectin, and GOT/GPT were measured. Also, white adipose tissue, liver weight, abdominal fat mass, hepatic lipid contents, and mRNA expression of obese-associating genes were examined in obese mice. Results In high fat diet-fed mice, HDYST administration significantly decreased body weight, diet efficiency ratio, serum levels of total cholesterol, triglyceride, LDL-cholesterol, as well as leptin and GOT/GPT, compared to the HFD group in a dose-dependent manner. HDYST increased significantly the serum levels of HDL-cholesterol and adiponectin. It also reduced the accumulation of lipids, such as total lipid and triglycerides, in organs such as liver and abdominal adipose tissue. Moreover, HDYST administration significantly decreased the expression levels of fatty acid synthetic genes, such as sterol regulatory element-binding protein-1c (SREBP-1c), FAS and Stearoyl-Coenzyme A desaturase 1 (SCD-1), in the liver tissues, while it increased the messenger RAN (mRNA) levels of fatty acid catalytic genes, such as Peroxisome proliferator activated receptor alpha (PPAR-${\alpha}$), acyl-COA oxidase (ACO), and Carnitine palmitoyltransferase-1a (CPT-1a). Conclusions Based on the results above, HDYST reveals anti-obesity effects declining body fat accumulation through the regulation of fatty acid metabolism and leptin/adiponectin serum levels. It therefore suggests that HDYST can be clinically useful for the treatment of obesity.

Objective : This study was conducted to observe the anti-hyperlipidemic and anti-inflammatory effects, as well as the metabolic benefits, of pear extract and herbal drug mixture (Lycii Fructus, Coicis Semen, Alimatis Rhizoma, and Astragali Radix) on rats fed with a high fat diet. Methods : The animals used were male rats and the control group was fed a high fat diet only. The experimental groups were divided into four. Exp I group was fed a high fat diet with a mixture of pear extract and 3% Lycii Fructus; Exp II group was fed a high fat diet with a mixture of pear extract and 3% Coicis Semen; Exp III group was fed a high fat diet with a mixture of pear extract and 3% Alimatis Rhizoma; and Exp IV group was fed a high fat diet with a mixture of pear extract and 3% Astragali Radix for 4 weeks. Results : The body weight gain increased in all groups, but attenuated gradually in the experimental groups compared to the control group. The food intakes were significantly lower in Exp I and Exp III groups than the control group. The concentrations of serum total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, and triglyceride (TG) were significantly higher in Exp II than in the control group, and lower in Exp III group than in the control group. Also the concentration of serum free fatty acid was significantly lower in the Exp III group than in the control group. In inflammatory activities, the Exp II group was significantly lower than the control group. Conclusion : The results indicated that Exp III group (administered a mixture of pear extract and Alimatis Rhizoma) most efficiently reduced fat accumulation and body weight, while the Exp II group (administered the mixture of pear extract and Coicis Semen) had the highest elevated lipid metabolism and immune activity.

BACKGROUND/OBJECTIVES: We investigated the effects of a combination of grape pomace (Vitis labrusca, Campbell Early) and Omija fruit (Schizandra chinensis, Baillon) ethanol extracts on lipid metabolism and antioxidant defense system in diet-induced obese mice. MATERIALS/METHODS: Forty male C57BL/6J mice were divided into four groups and fed high-fat diet (control group, CON) or high-fat diet added 0.5% grape pomace extract (GPE), 0.05% Omija fruit extract (OFE) or 0.5% GPE plus 0.05% OFE (GPE+OFE) for 12 weeks. RESULTS: In contrast to the GPE- or OFE-supplemented groups, the GPE+OFE group showed significantly lower body weight and white adipose tissue weights than the CON group. Moreover, GPE+OFE supplementation significantly decreased plasma total cholesterol and increased the plasma HDL-cholesterol/total-cholesterol ratio (HTR) compared to the control diet. The hepatic triglyceride level was significantly lower in the GPE+OFE and GPE groups by increasing ${\beta}$-oxidation and decreasing lipogenic enzyme compared to the CON group. Furthermore, GPE+OFE supplementation significantly increased antioxidant enzyme activities with a simultaneous decrease in liver $H_2O_2$ content compared to the control diet. CONCLUSIONS: Together our results suggest that supplementation with the GPE+OFE mixture may be more effective in improving adiposity, lipid metabolism and oxidative stress in high-fat diet-fed mice than those with GPE and OFE alone.

The effect of conjugated linoleic acid (CLA) isomers esterified in diacylglycerol (DAG)-rich oil on lipid metabolism was investigated. Since dietary DAG has been known to induce the regression of atherosclerosis, CLA-DAG and olive-DAG oils containing similar levels of DAG (51.4~54.2%) were synthesized from olive oil. Hyperlipidemic C57BL/6J mice were then fed high-fat high-cholesterol diets supplemented with these oils (5% each) for 7 wk. The CLA-DAG diet containing 2.1% CLA isomers (0.78% c9,t11-CLA; 1.18% t10,c12-CLA) remarkably increased the levels of total plasma cholesterol and glutamic oxaloacetic transaminase (GOT) along with hepatic cholesterol and triacylglycerol (TAG) contents. Furthermore, the CLA-DAG diet inhibited fat uptake into adipose tissue whereas fat deposition (especially in the liver) was increased, resulting in the development of fatty livers. Hepatic fatty acid composition in the CLA-DAG mice was different from that of the olive-DAG mice, showing higher ratios of C16:1/C16:0 and C18:1/C18:0 in the liver. The activity of hepatic acyl-CoA:cholesterol acyltransferase (ACAT) was higher in CLA-DAG mice while plasma lecithin:cholesterol acyltransferase (LCAT) activity and the ferric reducing ability of plasma (FRAP) were lower in CLA-DAG mice compared to the olive-DAG animals. Results of the present study suggest that CLA incorporation into DAG oil could induce atherosclerosis in mice.

This study was performed to investigate the increase of S-allylcysteine content, a biomarker of black garlic, during its aging period, as well as the serum lipid-lowering effects of black garlic extract in high fat diet fed rats. The highest content of S-allylcysteine was observed on the 15th day of the aging period. Sensory evaluation was also estimated to be extremely good on the 15th day of the aging period. High fat diet rats with induced hyperlipidemia were fed diets containing black garlic extract of low, medium, and high doses for 6 weeks. No significant difference in body weight gain and food efficiency was observed between normal, placebo and black garlic fed groups. Liver weight was significantly higher in black garlic fed groups than in the normal group. Total serum cholesterol and triglyceride were significantly lower in low, medium, and high dose groups than in the normal group. Also, HDL-cholesterol was significantly higher and LDL-cholesterol was significantly lower in black garlic diet fed groups than in the normal group. Hepatic levels including total lipid and cholesterol were especially decreased in the black garlic diet fed group than in the placebo group. These results suggest that black garlic intake reduces the levels of serum and hepatic cholesterol in high fat diet fed rats. In conclusion, black garlic has a potential to be used as a functional health food ingredient with beneficial effects on lowering cholesterol and triglyceride levels.

The extracts of hoelen was evaluated for protective effects against the adverse effects of a high fat diet. Mice were divided into four groups; normal diet (control), high fat (HF) diet, high fat+water extract (HF+WE) and high fat+ethanol extract (HF+EE) and fed for 4 weeks. Food calorie consumptions were not significantly different between groups. Weight gain was significantly lower in HF+EE than the high fat group. Also, liver weight was significantly lower in HF+EE than the control group. The weight of epididymal fat tissue was 1.4 fold higher in high fat groups than control group. The concentration of serum triglyceride, total cholesterol and LDL-cholesterol increased in high fat group, but decreased by hoelen ethanol extract administration. Also serum HDL-cholesterol was decreased in the high fat group, but increased by the hoelen ethanol extract administration. Liver triglyceride and total cholesterol were not significantly different among groups. These data suggest that hoelen ethanol extract administration improves the serum lipid profiles of mice.
