Objectives : Samhwangsasim-tang (SHSST) is a traditional Korean medication, which has been used in Korea for treatment of hypertension and chest pain. Hyperlipidemia and inflammation could influence hypertension and chest pain. This study investigated whether and how SHSST reduces the hyperlipidemia and inflammation related to high-cholesterol diet-induced obesity in rats. Methods : Mice were divided randomly into four groups: the normal diet group, high-cholesterol diet group, low dose treatment group supplemented with 30% ethanol extract of SHSST (L) and high dose treatment group supplemented with 80% ethanol extract of SHSST (H). L and H groups were orally administered with SHSST at the dose of 50mg/kg a day respectively and others were administered with the same volume of physiological saline. Results : Administration of SHSST resulted in a decrease in serum levels of total cholesterol and low-density lipoprotein. Expression of hepatic genes(SREBP2, LXR, LDLR, and HMG-CoA) related with cholesterol metabolism was also suppressed. In addition, SHSST decreased the expression of inflammation-related gene (TNF-${\alpha}$, IL-6, ICAM-1, VCAM-1, TGF-${\beta}1$ and fibronectin). Histological examinations also showed that the size of the adipocytes was smaller in the SHSST treated group than in the high-colesterol diet group. In an in vitro study, SHSST inhibited the production of nitric oxide in a concentration-dependent manner. Conclusions : This study indicates that SHSST has anti-hyperlipidemia and anti-inflammatory effects. It may also suggest that SHSST may be alternative therapy for treatment of hyperlipidemia and its complications.

This study aimed to investigate the effect of acorn powder and starch on the blood parameters of mice fed a high-fat diet. The moisture, crude ash, crude protein, and crude fat contents of acorns were $37.99{\pm}0.37%$, $1.61{\pm}0.06%$, $4.36{\pm}0.18%$ and $3.22{\pm}0.15%$, respectively. Acorn powder and starch contains antioxidant minerals such as selenium and zinc. The iron content was significantly higher in acorn powder than in acorn starch (p<0.05). The total cholesterol concentration was $148.50{\pm}29.72mg/dL$ in the high-fat starch diet (HFS) group, while in the high-fat diet (HF) group it was $201.50{\pm}39.15mg/dL$ (p<0.05). Serum LDL-cholesterol concentrations were significantly lower in the HFS group ($50.50{\pm}10.79mg/dL$) than in the HF group ($62.00{\pm}20.85mg/dL$; p<0.05). The serum $IL-1{\beta}$ levels in mice were not significantly different between the groups. IL-10 levels were higher in the HFP group than other groups. There is a need for strong recognition that acorns are good ingredients worldwide. It is required to develop various products using acorn powder and starch powder. There is also a need for a strategy to globalize food using acorns.

This study was carried out to investigate the clinical effects of Tongbiyeum(TBY) ₂on hyperlipidemia. The hyperlipidemia of rats was induced by feeding high cholesterol diet for 4 weeks. We checked serum lipids and body weight weekly for 4 weeks. After the termination of treatment, we measured liver weight and observed histopathological change. We compared result of TBY group with control group. Thereafter, we made a study of 37 hyperlipidemic patients who visited us, the oriental medical center Daejeon and cheongju of Daejeon University, from November, 2001 to April, 2002. After administering TBY for 1 month, we followed up their total cholesterol, triglyceride and HDL-Cholesterol levels. The results were as follows; TBY treatment inhibited the liver weight gain induced by high cholesterol diet as compared with control group. TBY treatment inhibited lipid droplet accumulation and apoptotic change in liver as compared with control group. TBY treatment significantly inhibited the increasing of serum triglyceride and total cholesterol levels induced by high cholesterol diet as compared with control group but not affect HDL-cholesterol level. After administering TBY, the serum total cholesterol, triglyceride and LDL-cholesterol levels of hyperlipidemic patients were decreased significantly. After administering TBY, the serum HDL-Cholesterol level of hyperlipidemic patients had no significant changes. According to above mentioned results, we can infer that TBY has hypolipidemic effect to be applicable to artheriosclerosis.

BACKGROUND/OBJECTIVES: An imbalanced adipokine profile in obesity increases the susceptibility to obesity-related cardiometabolic alterations, including type 2 diabetes, hypertension, dyslipidemia, and non-alcoholic fatty liver disease. The mulberry plant has been reported to have health benefits, such as hypolipidemic and hepatoprotective effects. This study examined the effects of a mulberry (Morus alba L.) fruit ethanol extract (MBEE) on dyslipidemia, liver steatosis, and adipokine imbalance in response to a high-fat diet. MATERIALS/METHODS: Male Sprague-Dawley rats were assigned to one of 4 groups containing 6 rats each and fed either a control diet (CON), a high-fat diet (HFD), or a high-fat diet with MBEE of 150 mg/kg/day (LMB) or 300 mg/kg/day (HMB). The triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activities were measured spectrophotometrically. The leptin, adiponectin, and plasminogen activator inhibitor-1 (PAI-1) levels were determined by an enzyme-linked immunosorbent assay. RESULTS: The plasma TG levels were similar in the 4 groups. Plasma cholesterol and low-density lipoprotein cholesterol (LDL-C) levels and TC/HDL-C ratio increased in the HFD group compared with the CON group, whereas those values decreased in the LMB group (P < 0.05), indicating that MBEE had a plasma lipid-lowering effect. HDL-C decreased in the HFD group, but MBEE did not affect the HDL-C level. The HFD rats significantly increased hepatic TG and cholesterol levels and plasma ALT and AST activities compared to the CON group. The hepatic TG level and ALT and AST activities were reduced markedly by the MBEE treatment. The HFD group showed a higher PAI-1 level, whereas MBEE treatment, especially in the HMB group, significantly reduced leptin level, and leptin/adiponectin and PAI-1/ adiponectin ratios. These findings suggest that MBEE altered the imbalance between the pro-and anti-inflammatory adipokines to a more anti-inflammatory state. CONCLUSIONS: MBEE could protect against abnormal lipid metabolism and hepatic steatosis induced by a high-fat diet, lowering plasma cholesterol, LDL-C and TC/HDL-C, and hepatic TG. These findings are associated with the regulating effect of MBEE on the leptin/adiponectin and PAI-1/adiponectin ratios.

This study was performed to investigate the changes of the serological lipid-related parameters of the rats when they were fed with the high fat diets supplemented with or without naringin for five weeks. Twenty-four Sprague-Dawley male rats($272.2{\pm}7.2$ g of body weight) were randomly divided into three groups(eight rats per each group) : control(C) group and two treatment groups. Rats in the C group were fed with the high-fat diet containing 15% lard, 1% cholesterol and 0.5% sodium cholate(w/w) which was modified from the formula of the American Institute of Nutrition-76(AIN-76) diet. Rats in treatment groups were fed with above diet supplemented with 0.1% naringin(N-0.1) or 0.2% naringin(N-0.2) on the weight to weight basis, respectively. The supplementation of naringin did not induce any significant difference on the final body weight, gain of body weight, the amount of feed intake and the feed efficiency of rats in between control and treatment groups. In addition the levels of glucose, total protein, albumin, globulin and albumin/globulin(A/G) ratio in sera of rats showed no significant differences between control and treatment groups. The levels of total cholesterol(TC) and low density lipoprotein-cholesterol(LDL-C)in sera of rats in both N-0.1 and N-0.2 groups were significantly lower than in C group(p<0.05). The levels of high density lipoprotein-cholesterol(HDL-C) were significantly higher in both N-0.1 and N-0.2 groups than in C group(p<0.05). The values of atherogenic index(AI) were significantly lower in both N-0.1 and N-0.2 groups than in C group(p<0.05). The levels of triglyceride in sera of rats showed no significant differences between control and treatment groups. The values of AST and ALT were significantly lower in both N-0.1 and N-0.2 groups than in C group(p<0.05). Therefore the supplementation of naringin to high fat diet in rats reduced effectively the serum lipid levels such as TC and LDL-C and AI which were regarded as to cause the cardiovascular diseases, and moreover it elevated the HDL-C value effectively which was regarded to protect cardiovascular diseases.

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.
