BACKGROUND/OBJECTIVE: We examined the hypoglycemic and anti-hyperlipidemic effect of yeast hydrolysate (YH) enriched with Cyclo-His-Pro (CHP) in the C57BL/6J ob/ob mouse model. MATERIALS/METHODS: Mice were separated into 4 groups (8 mice/group) on the basis of blood glucose and body weight: WT control, lean mice given vehicle; ob/ob control, ob/ob mice given vehicle; YH-1, ob/ob mice given 0.5 g/kg of YH; YH-2, ob/ob mice given 1 g/kg of YH. YH in saline or vehicle was administered orally in the same volume every day for 3 weeks. RESULTS: Mice treated with YH (0.5 and 1 g/kg) for 3 weeks displayed a significant reduction in overall body weight gain and perirenal and epididymal adipose tissue weight compared to the ob/ob control group. Additionally, high-density lipoprotein (HDL) cholesterol, glucose, and atherogenic indexes were significantly decreased in the blood of YH-1 and YH-2 groups compared to the ob/ob control. In ob/ob mice, YH administration significantly improved glucose tolerance and blood insulin levels. These data indicate that YH treatment produces potent hypoglycemic and anti-hyperlipidemic effects by controlling body weight, fat mass, blood lipid, insulin levels, and glucose tolerance. CONCLUSION: YH could potentially be used as a treatment option for diabetes and hyperlipidemia. The CHP-enriched YH may be a promising strategy in the development of hypoglycemic peptide nutraceuticals.

Background: An imbalance in energy intake and expenditure can cause obesity, which is a major risk factor for chronic diseases such as heart disease, type 2 diabetes, insulin resistance, cancers and hyperlipidemia. Methods and Results: In this study, we evaluated the anti-obesity effects of a water extract from the young leaves of barley sprout (BS) in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice (HF). Lipid accumulation measurement indicates that BS markedly inhibited adipogenesis by reducing lipid droplet production in a dose-dependent manner. Furthermore, the mRNA expression of adipogenic transcription factors peroxisome proliferator-activated receptor-${\gamma}$ and fatty acid synthetase, CCAAT/enhancer binding protein-${\alpha}$ and fatty acid binding protein 4 in 3T3-L1 cells was significantly inhibited by BS treatment. In an in vivo test, the BS-administered group of HFD-induced mice showed less body weight gain, and lower liver and epididymal white adipose tissue weights. The BS-treated mice showed decreased serum levels of leptin and lipids compared to untreated HFD mice and the levels of adiponectin and the HDL-cholesterol/total cholesterol ratio increased. These results indicate that BS inhibits body fat accumulation by reducing the mRNA expression of lipogenesis transcription factors and increasing serum adipokine concentration in in vitro and in vivo tests. Conclusions: BS reduced high fat diet-induced weight gain and had a positive effect on dyslipidemia.

Scutellaria baicalensis Georgi (Scutellariae Radix) has been widely used as a dietary ingredient and traditional herbal medicine such as diuretic, hyperlipidemia, antibacterial, anti-allergy, anti-inflammatory and anticancer properties. In this study, the isolation of biomarkers or bioactive compounds from complex S. baicalensis extracts represents an essential step for de novo identification and bioactivity assessment. The bioactive fraction consisted of eight compounds which was chromatographed on an analytical high performance liquid chromatography column using two different gradient runs. A simulative replacement of the analytical column with a medium pressure liquid chromatography and open column allowed the determination of gradient profile to allow sufficient separation in the preparative scale. From the optimized method, eight standard compounds have been identified in the fractions. In addition, MS, UV, HRMS detection was provided by ultraperformance liquid chromatographyequadrupole time-of-flight mass spectrometry (UPLC-QTof-MS) of all fractions. Therefore, this scale up procedure was successfully applied to a S. baicalensis extract.

This study was performed to observe the effects of the feeding physiological activity substance in Cordyceps militaris hot-water extract intake on the improvement of lipid components and metabolic enzyme activities in the serum of dietary hyperlipidemic rats (SD strain, male) fed the experimental diets for 5 weeks. The concentrations of cholesterol (total cholesterol, ${\beta}$-lipoprotein, LDL-cholesterol, free cholesterol and cholesteryl ester), atherosclerotic index, triglyceride (TG), phospholipid (PL) and blood glucose in sera were remarkably lower in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. In the ratio of HDL-cholesterol concentration was higher percentage in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. The activities aminotransferase (AST, ALT) in sera were rather lower in the Cordyceps militaris extract administration than in the hyperlipidemic rats. From the above research, Cordyceps militaris extract were effective on the improvement of the lipid compositions in sera of dietary hyperlipidemic rats.

Breastfeeding is highly recommended due to its benefits for both the infant and mother; however, most mothers predominantly use formula feed. Breastfeeding affords protection against a wide variety of medical conditions that may emerge at different time points over the lifespan, including hospital admissions for respiratory infections and neonatal fever, offspring childhood obesity, and cancer as well as cardiovascular disease, hyperlipidemia, hypertension, and diabetes. Moreover, breastfeeding is expected to decrease the risk of adolescent depression and other psychopathologies. It is also important for the development of the gut, gut-brain axis, and immune system, and night-time breast milk is likely to have higher antioxidant, anti-inflammatory, and immune regulatory effects due to the impact of breast milk melatonin on the infant's developing microbiome and gut permeability. Melatonin can be added to a night-time-specific formula feed; however, it is not included in the Korean Food Additive Codex.

This study sought to investigate the ameliorating effects of a Korean medicinal herb (KMH) complex on the impacts of alcohol consumption in rat hepatocytes and in reducing the total cholesterol levels and the total lipid levels in the serum. We compared the body weight gain and ratio of the liver, the kidney to body weight, and also the serum biochemistry of the rats administered with both the alcohol and the KMH complex to the control rats treated with alcohol alone. The clinically important enzyme markers (Aspartate Aminotransferase, AST, and Alanine Aminotransferase, ALT) of rats, administered with both the alcohol and the KMH complex treatments, were compared with those in the control group. The treatment regimen (KMH complex) significantly reduced the serum AST and ALT levels, indicating the hepato-protective effects of the KMH complex. Furthermore, total cholesterol and total lipid levels were significantly reduced. These results indicate that the KMH complex may positively mediate the effects of alcohol on hepatocytes and the general liver functions.

Recently, the prevalence of hyperlipidemia has been increasing, and consequently, the need to identify safe and effective treatments to control this chronic disease has also increased. The beneficial effects of probiotics have been revealed by several studies over the past few years, including their effects on hypertriglyceridemia. However, the mechanisms of action of probiotics are still unclear. The anti-obesity effects of Lactobacillus plantarum Q180 on lipid accumulation have already been demonstrated using an in vitro HepG2 cell model, and therefore, we investigated its efficacy and mechanism of action. Lipid accumulation was induced in HepG2 cells by palmitic acid treatment and then the cells were incubated with L. plantarum Q180 lysate or supernatant to investigate changes in lipid accumulation and expression of lipid metabolism-related genes. The results showed that the L. plantarum Q180-treated group exhibited significantly lower levels of lipid accumulation and mRNA expression of lipid synthesis- and adipogenesis-related genes than the palmitic acid-treated group did. These results indicate that L. plantarum Q180 may contribute to alleviating hypertriglyceridemia by inhibiting lipid synthesis.

The antioxidant activity of resveratrol in cholesterol-fed rats, along with its hypolipidemic effects was determined. Thirty two male Sprague-Dawley (SD) rats were randomly divided into three groups (Control, Res30 and Res70) and fed a hyperlipidemic diet for 4 weeks. Resveratrol was suspended in 0.3% carboxymethyl cellulose (CMC) solution and given to rats of the Res30 and Res70 groups once a day for 4 weeks by oral intubation at a dose of 30 and 70 mg/kg body weight, respectively. The control group received 0.3% CMC solution alone. Resveratrol significantly lowered serum lipid, hepatic cholesterol (TC) and triglyceride (TG) levels compared to the control. Excretion of bile acids was significantly enhanced by resveratrol. The overall potential of the antioxidant system was significantly enhanced by the resveratrol as plasma and hepatic thiobarbituric acid reactive substances (TBARS) levels were lowered while serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) activities were increased in the cholesterol-fed rats. These findings suggest that resveratrol maintains an antioxidant efficacy as well as its anti-hyperlipidemic effect.

Anti-hyperlipidemic effect of red ginseng (RG; the steamed root of Panax ginseng C.A. Meyer) and Crataegii fructus (CF, the fruit of Crataegus pinnatifida BGE), which are used frequently in China and Korea as herbal medicines to treat arteriosclerosis, were investigated. Treatments of RG and CF significantly reduced blood triglyceride (TG) and total cholesterol (TC) levels in Triton WR-1339-induced hyperlipidemic mice and serum TG levels in corn oil-induced hypertriglyceridemic mice. Ginsenoside Rg3 and ursolic acid, the main constituents of RG and CF, respectively, also reduced TG and TC levels in hyperlipidemic mice. RG and CF significantly lowered the high blood TG and TC levels and body and epididymal mass weights induced by long-term feeding of a high-fat diet and increased the high-fat diet-induced decrease in blood HDL cholesterol levels. RG and Rg3 reduced the blood TC levels more than CF and ursolic acid. However, blood TG level were reduced by CF and ursolic acid more than RG and Rg3. RG, CF, and their constituents also inhibited pancreatic lipase and HMG-CoA reductase activities. The most potent inhibitor was Rg3. These findings suggest that RG and CF may be suitable for the therapies of hypercholesterolemia and triglyceridemia, respectively.

Background and Purpose : Chunghyul-dan has been widely used in the Department of Cardiovascular ＆ Neurologic Diseases, Kyung Hee Oriental Medical Center to prevent stroke by lowering serum cholesterol level. Previous experimental and clinical studies revealed that Chunghyul-dan had therapeutic effects on hyperlipidemia by inhibiting HMG-CoA reductase and pancreatic lipase. It was also reported that Chunghyul-dan showed an anti-oxidation effect by scavenging free radicals and inhibiting nitric oxide synthesis. Therefore, we examined the safety of Chunghyul-dan on all subjects who had been treated with it. Methods : We performed a retrospective study by reviewing the medical records of those who had been administrated Chunghyul-dan at Kyung Hee Oriental Medical Center from February 8,2001 to December 31,2002. The subjects' general characteristics (gender, age, medical history, and present illness), recorded adverse effects, and the results of laboratory findings were obtained and analyzed to assess the clinical safety of Chunghyul-dan. Results : Six hundred fifty six subjects were treated with Chunghyul-dan. Clinical adverse effects appeared in 13 subjects, the major symptom being indigestion (8 subjects). The apparent frequency of adverse effects was much lower than that in previous reports on the safety of certain medications. On investigation of laboratory findings, we could not find any hepatic or renal toxicity. Conclusion : We suggest that our results contribute towards confirming the safety of Chunghyul-dan by offering clinical evidence.
