This study was conducted to investigate the effect of dietary supplementation of octacosanol (OCT) extracted from triticale sprout on laying performance, egg quality, and blood parameters of laying hens. A total of 192, Hyline brown laying hens aged 43 weeks were divided into 4 dietary groups of 48 birds each and they were randomly subjected to one of the experimental diets containing OCT at the levels of none, 10, 20, and 30 mg/kg of diet. All birds were fed with isoenergetic and isonitrogenous mash diets for 6 weeks. The result showed that hens supplemented with 20 and 30 mg/kg OCT in diet significantly increased (p < 0.05) egg production than those fed with the basal diet. OCT concentration in the egg yolk of hens fed with 20 and 30 mg/kg OCT was significantly higher than in those fed the control diet. Hens fed 20 and 30 mg/kg OCT exhibited greater high-density lipoprotein (HDL) cholesterol and interleukin (IL) concentrations and reduced serum concentrations of cholesterol and triglyceride compared to those fed with 0 and 10 mg/kg OCT. This study indicates that supplementing the diet of laying hens with 20 and 30 mg/kg of OCT can improve the performance, egg quality, and health status of laying hens.

This study was designed to evaluate antihyperglycemic and antihyperlipidemic effects of ethanol extracts of Taraxacum mongolicum(T.m.) on streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were randomly assigned to five groups: normal (NC), STZ-control (DC), and three experimental groups. Diabetes was induced in Sprague-Dawley rats with a single intravenous injection [45 mg/kg body weight (b.w.)] of STZ. An ethanol extract of T.m. was orally given to diabetic rats for 14 days. Three experimental groups were additionally treated with T.m. extract at doses of 1 g/kg b.w./day for T.m.-1, 2 g/kg b.w./day for T.m.-2, and 3 g/kg b.w./day for T.m.-3. Oral administration of T.m.-2 significantly increased their body weights. T.m.-1 and T.m.-2 significantly decreased aspartate aminotransferase (AST) levels than DC. T.m.-1 and T.m.-2 group significantly decreased blood glucose levels. Total cholesterol, triglycerides, and free fatty acids were significantly decreased whereas high-density lipoprotein cholesterol was significantly increased in groups treated with T.m. extract than those in the DC group. These results support the fact that administration of T.m. extract can reduce hyperglycemia and hyperlipidemia risk in diabetic rats.

The purposes of this study were to investigate the effects of acute exercise on blood vaspin, glucose level, and inflammatory cytokines in middle-aged women with pre-diabetes. Nineteen middle-aged women (normal women, n = 11) and women with pre-diabetes(n = 8), who were apparently healthy and not taking any medications affecting their blood pressure or blood glucose, participated. Body fatness parameters including body mass index, body fat percentage, and waist circumference were measured using a bio-impedance analyzer. Resting blood pressure was measured in duplicate, and mean values were used for the data analysis. Regardless of group assignments, all subjects participated in a 3-day consecutive walking exercise at an intensity of 65% VO_2max targeting an energy expenditure of 1200 kcal (400 kcal per day). The major outcome variables included total cholesterol, triglycerides, high-density lipoprotein cholesterol, glucose, vaspin, interleukin-6, and adiponectin levels. Unlike normal women, women with pre-diabetes had a significant improvement in the homeostatic model assessment of insulin resistance (p < 0.025) with no significant group difference in response to acute exercise. The findings suggest that acute exercise results in a significant improvement in insulin sensitivity without any change in serum vaspin levels in women with pre-diabetes.

BACKGROUND/OBJECTIVES: Obesity is a major cause of metabolic disorders; to prevent obesity, research is ongoing to develop natural and safe ingredients with few adverse effects. In this study, we determined the anti-obesity effects of Rosa multiflora root extract (KWFD-H01) in 3T3-L1 adipocytes and Sprague-Dawley (SD) rats. MATERIALS/METHODS: The anti-obesity effects of KWFD-H01in 3T3-L1 adipocytes and SD rats were examined using various assays, including Oil Red O staining, gene expression analyses, protein expression analyses, and blood biochemical analyses. RESULTS: KWFD-H01 reduced intracellular lipid accumulation and inhibited the mRNA expression of peroxisome proliferator-activated receptor γ (PPARγ), cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding proteins (C/EBPα), sterol regulatory element-binding transcription factor 1 (SREBP-1c), acetyl-CoA carboxylase (ACC), and fatty acid synthase (FAS) in 3T3-L1 cells. KWFD-H01 also reduced body weight, weight gain, and the levels of triglycerides, total and LDL-cholesterol, glucose, and leptin, while increasing high-density lipoprotein-cholesterol and adiponectin in SD rats. PPARγ, C/EBPα, SREBP-1c, ACC, and FAS protein expression was inhibited in the epididymal fat of SD rats. CONCLUSION: Overall, these results confirm the anti-obesity effects of KWFD-H01 in 3T3-L1 adipocytes and SD rats, indicating their potential as baseline data for developing functional health foods or pharmaceuticals to control obesity.

Objectives: Schizandrae fructus (Schizandra chinensis) is one of very common herbs, it is known as natural antioxidants, anti-inflammatory agent. Also some reports show that its extract works to regulate of dyslipidemia. This study was designed to investigate the effects of Schizandrae fructus chloroform fraction (SFCF) on serum lipid levels in dyslipidemic mice. Methods: The levels of total cholesterol, high density lipoprotein-cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), fasting blood glucose in serum were measured. Histopathological and gene expression changes in liver tissue were also observed. Results: Oral administration of SFCF lowered levels of total cholesterol and triglyceride, which were elevated by high-fat diet. But SFCF did not affect on weight changes and serum AST, ALT levels in dyslipidemic mice. After carrying out gene ontological analysis, large numbers of genes in high-fat diet group were up-(347) or down-regulated (235). In SFCF treated mice, some changed expression of the genes was restored to normal levels, with a recovery rate of 17%. And it seems that fatty acid biosynthesis pathway was one of important key pathways to recovery. Conclusions: SFCF has beneficial effect on dyslipidemia, and could be used to prevent and treat cardiovascular disease.

Male mice (ddY strain) were fed a laboratory chow diet containing the water extract from stem bark of Rhus verniciflua Stokes (RVS) for 14 days. There were no significant difference in body weight gain, feed intake, the hepatic lipid profile and serum total cholesterol and phodpholipid concentrations. The concentration of triglyceride in serum was significantly lower in the RVS group than that in the control group. The concentration of high-density-lipoprotein cholestrol in serum was significantly higher in the RVS group than that in the control group. The methanol extract from RVS stem bark effectively inhibited the formation of thiobarbituric acid-reactive substances as a marker of lipid peroxidation of liver microsomes in a concentration-dependent manner. This study showed that the water extract from stem bark of RVS decreased the serum triglyceride concentration and methanol extract has an antioxidative activity.

Tomatoes are rich in nutrients and have many beneficial advantages on human health. Four cherry tomato supplementation diets (CTSDs) were prepared from the juice and cake of fresh and processed (heat-treated) cherry tomatoes. Rats were fed CTSDs for 28 days and the changes in health indices in the serum were analyzed. CTSDs significantly decreased (P < 0.05) food efficiency ratio compared with the control. CTSD feeding significantly increased (P < 0.05) the high-density lipoprotein cholesterol level compared with the control, which resulted in a significant (P < 0.05) decrease in coronary artery risk index and atherogenic index. Furthermore, CTSD feeding increased serum serotonin level. These results indicate that CTSD shows antihyperlipidemic effect.

Two experiments were conducted to investigate the effect of feeding cyanidin 3-glucoside (C3G) high black rice bran on nutrient digestibility, blood measurements, growth performance and pork quality of pigs. In Exp. I, a total of fifteen pigs (19.91${\pm}$1.80 kg, average initial body weight) were used in assay of nutrient digestibility and blood measurements. All pigs were allotted to 5 treatments with 3 replicates according to a completely randomized design (CRD) in an individual metabolic crate. Treatments included 1) CON: basal diet, 2) BRB-2: basal+brown rice bran 2%, 3) BRB-4: basal+brown rice bran 4%, 4) CRB-2: basal+C3G high black rice bran 2% and 5) CRB-4: basal+C3G high black rice bran 4%. The digestibility of dry matter (DM), crude protein (CP), crude fat (CF), crude ash (CA) and crude fiber (CF) was not affected by dietary treatments. Serum triglyceride (TG) and high density lipoprotein (HDL) cholesterol concentrations were not affected by addition of C3G high black rice bran. However, at the end of experiment, pigs fed rice bran showed decreased tendency in total cholesterol concentration. Especially pigs fed C3G high black rice bran showed significantly lower total cholesterol concentration compared to pigs fed brown rice bran (p<0.03). There was numerically lower total cholesterol concentration with increasing levels of black rice bran in the diet. In terms of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT), there were no significant differences among treatments, even though pigs fed CRB-4 showed the lowest GOT concentration compared to other pigs. In Exp. II, sixteen finishing pigs (average initial body weight 89.96${\pm}$0.35 kg) were divided into 4 treatments to investigate the effect of feeding C3G high black rice bran on growth performance and pork quality. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among the treatments. Pigs fed C3G high black rice bran showed numerical decrease in ADG and increase in FCR while not effecting feed intake. There was no significant difference in live weight, carcass weight, carcass rate, backfat thickness and carcass grade. However, pigs fed C3G high black rice bran tended to show lower backfat thickness than pigs fed basal diet. Pigs fed C3G high black rice bran showed a tendency of decreased TBA value than pigs fed basal diet, although there was no overall significant difference among treatments. In conclusion, nutrient digestibility, blood measurements, growth performance and pork quality were not significantly affected by feeding C3G high black rice bran to pigs. However, C3G high black rice bran might have an effect on lowering serum total cholesterol and decrease the TBA value in pork compared to control group and these effects might be due to high concentration of antioxidative compounds in C3G high black rice bran.

섬애약쑥 가공품 개발 및 그 활성 규명을 위한 연구의 일환으로 섬애약쑥 물 추출물을 이용하여 식혜를 제조해 당화시킨 후 알코올 발효와 초산발효를 차례로 거쳐 식초를 완성하였다. 고지방-고콜레스테롤 식이를 제공한 흰쥐에 섬애약쑥 식초를 경구 투여하여 체내 지질대사에 미치는 영향을 분석하였다. 실험군은 일반식이를 급이한 정상군(N), 고지방-고콜레스테롤 식이를 급이한 대조군(C), 대조군 식이 급이 후 콜레스테롤 치료 약물인 lovastatin을 20 mg/kg B.W. 투여한 양성대조군(PC), 섬애약쑥 추출물 대신에 물을 첨가하여 동일하게 제조한 맥아식초(TM)와 섬애약쑥 식초(TS)를 체중 kg당 2 mL씩 경구 투여한 군으로 나누었다. 4주간의 실험식이 급이 후 혈청 내 총 지질과 총 콜레스테롤 함량은 식초 급이군이 양성대조군보다 유의적으로 낮았으나 중성지질은 양성대조군과는 유의적인 차이가 없었고 대조군 보다는 유의적으로 낮았다. HDL-콜레스테롤은 식초 급이군과 양성대조군 간에 유의적인 차이 없이 정상군보다 낮았으나 대조군보다는 유의적으로 높았다. LDL-콜레스테롤은 섬애약쑥 식초 급이군에서 190.68 mg/dL로 정상군을 제외한 실험군 중 가장 낮은 함량이었고 동맥경화지수와 심혈관계 질환 위험지수도 동일한 경향이었다. 혈청 총 단백질과 알부민 함량은 맥아식초와 섬애약쑥 식초 급이군이 대조군이나 양성대조군보다 유의적으로 낮았다. 간 손상 지표가 되는 AST는 정상군과 식초 급이군 간에 차이가 없었다. 섬애약쑥 식초의 급이는 간장 내 지질 농도 개선에도 효과가 있어 간장 내 총 지질, 총 콜레스테롤 및 중성지질의 농도를 대조군보다 유의하게 감소시켰다. 혈청 내 지질과산화물의 함량은 섬애약쑥 식초 급이군에서 정상군과 유사한 수준으로 감소하였으며, 간 조직에서는 대조군보다는 낮았으나 정상군보다는 유의적으로 높은 함량이었다. 이러한 결과는 DPPH를 이용한 항산화 활성 평가에서도 유사한 경향으로 섬애약쑥 식초 급이군 혈청의 항산화 활성이 55.69%로 정상군과 유의차가 없었으며, 간 조직의 활성은 52.39%로 대조군과 유의적인 차이가 없었다. 이상의 결과로부터 섬애약쑥 식초는 혈중 지질 농도를 개선하는 효과가 있음을 확인하였으며, 이는 식초 자체의 활성과 자체에 함유되어 있던 유효성분 및 발효과정에서 새로이 생성된 성분들이 복합적으로 작용한 결과로 판단된다.
