  • It is known that onion increases antioxidative and antibiotic capacity, and decreases blood pressure and cholesterol levels. The study was carried out to investigate whether ethanol extract of onion can enhance blood lipid profiles in hypercholesterolemic patients. Foully three hypercholesterolemic patients were randomly divided into 2 groups; 25 in controls and 18 in experimental group. The control group was offered to take placebo for 4 weeks (200 ml/day), and experimental group was offered to consume ethanol extract of onion for 8 weeks (200 ml/day that corresponds to 500 g of onion). There were no differences in sex, age, body mass index (BMI) and educational levels between groups before treatment. After 8 weeks of onion extract consumption, plasma triglycerides level was significantly decreased in experimental group compared to control (p<0.05). Total cholesterol level was tended to decrease in experimental group, but there was no significant difference of change between control and experimental group. The levels of plasma glucose and LDL-cholesterol were not changed significantly after onion extract consumption. In summary, alcohol extract of onion may have a positive effect on the lipid profiles of hypercholesterolemia patients through decreasing plasma triglyceride concentration.

  • This study was conducted to investigate the effect of bisphenol A (BPA; 4,4' -isopropylidenediphenol) on haematological parameters of Korean rockfish, Sebastes schlegeli in laboratory condition, Fish were randomly distributed into three treatment groups which were received of 0.1, 1 and 10 mg BPA $kg^{-1}$ body weight. They were injected four times intraperitoneally at days 0,3,7 and 12 with BPA. Control group was subjected to the same regime using an equal volume of 60% ethanol-mixed PBS carrier injection only. Fish from each group were sacrificed on day 15 after first injection for haematological assay. Observations on haematological parameters indicated BPA-treatment induced lower level of red blood cell counts and hemoglobin concentration. Serum chloride, calcium, glucose, bilirubin and blood urea nitrogen concentrations increased following exposure to BPA at 10 mg $kg^{-1}$ body weight. In contrast, serum cholesterol in fish exposed to BPA decreased. Serum transaminase and lactate dehydrogenase activities after the highest level of 10 mg $kg^{-1}$ PBA was significantly increased. These results demonstrate that BPA have induced adverse impact on haematological parameters in the Korean rockfish, Sebastes schlegeli.

  • This study was performed to investigate the growth rate, hematological and serological changes of the rats when they were fed with the high fat diets supplemented with or without the tannic acid for five weeks. Thirty-two Sprague-Dawley male rats(235.7\pm10.7g\;of\;body\;weight)$ were randomly divided into four groups, control group and three treatment groups(T1, T2 and T3). Rats in control group were fed with the high fat diet containing $15\%\;lard,\;1\%$ cholesterol and $0.5\%$ sodium cholate(wt/wt) which was modified from the formula of American Institute of Nutrition (AIN)-76 diet and rats in treatment groups were fed with above diet supplemented with $0.25\%(T1),\;0.5\%(T2)$ or $0.75\%(T3)$ of tannic acid(wt/wt), respectively. The supplementation of tannic acid(TA) did not affect the final body weight, gain of body weight and feed intake of rats in both control and treatment groups. The numbers of red blood cells, hemoglobin concentrations and hematocrit values in blood of rats showed no significant differences between control group and treatment groups. The glucose concentration and albumin/globulin(A/G) ratio of rats in treatment groups were slightly lower than that of control group without significance. The values of total protein, albumin and globulin showed no significant differences between control group and treatment groups. The values of total cholesterol, low density lipoprotein­cholesterol and atherogenic index in sera of rats in treatment groups were much lower than that of control group without significance. The values of triglycerides in sera of rats in T3 group were significantly lower than that of control group (p<0.05). The values of AST and ALT in sera of rats in T3 group were significantly lower than that of control group (p<0.05). Thus supplementation of tannic acid to high fat diet could be effective to reduce the serum lipid levels such as total cholesterol, high density lipoprotein-cholesterol and triglycerides which were regarded as to cause the cardiovascular diseases.

  • As a basic study to find bioactive principles for the hypolipidemic effect from natural sources, various biological influences of MeOH extracts of Thuja accidentalis L. and Juniperus chinensis var. horizontalis Nakai on rats were examined. The concentrates obtained from the organic layer and aqueous layer fractions of each species were orally administered to rats and then their effect on the body weight, organ weight, serum lipids profile, and blood glucose concentration were examined. Among the samples tested, the organic layer of Juniperus chinensis var. horizontalis exhibited the possibility of the hypolipidemic effects. The corresponding layer was chromatographed to give three fractions and reexamined their effects on rats. The results demonstrated that the fraction corresponding for the R$_{f}$ 0.4~0.7 which was the mixture of many minor components showed the effect of lowering the blood-lipid bevel effectively without any side effects. Besides, communic acid, identified from and isolated as a major component of the species exhibited the possibe hypolipidemic effects.s.

  • Objective: Present study was designed to evaluate the efficacy of Acacia nilotica bark extract as an alternative to antibiotic growth promoters in broilers. Methods: Six hundred, day-old broiler chicks were randomly divided into six groups (NC, without any supplementation; AB, NC+Zinc Bacitracin; PB, NC+Safmannan; ANBE1, NC+A. nilotica bark extract 0.1%; ANBE3, NC+A. nilotica bark extract 0.3%; ANBE5, NC+A. nilotica bark extract 0.5%), with ten replicates per group (10 chicks/replicate) and feeding trial was lasted for 35 days. Results: Results showed that weight gain (1,296.63 g) and feed conversion ratio (FCR, 1.59) of AB was better than NC, during the finisher phase. Overall FCR of AB (1.53), PB (1.54), and ANBE5 (1.54) was significantly (p<0.05) better than NC. From carcass parameters relative weight of wing and heart were highest in ANBE3 (2.5% and 1.51%, respectively). Significantly (p<0.05) highest blood glucose level was observed in NC (264.5 mg/dL) and highest albumin concentration was found in AB (1.46 mg/dL). In addition, antibody titer levels against ND and IBD were higher in ANBE5 than NC, while higher relative weight of bursa was observed in ANBE3 than NC. The villus height to crypt depth ratio in all experimental groups was better than NC. Conclusion: Acacia nilotica bark extract could be a suitable alternative to antibiotic growth promoters to support the growth in broilers.

  • The study was carried out to investigate the ratio of ethanol to n-propanol in blood and urine specimens, and developed a method for distinguishing ingested ethanol from artifactual ethanol in urine samples. In case of no urinary ethanol was detected, the ratio of ethanol to n-propanol concentration was about 12~20 times higher than those of blood. Therefore, it might be a good method to determine whether the detected ethanol is from drinking or from microbial fermentation. During the metabolism of ethanol, the levels of the metabolite of serotonin (5-hydroxytryptamine, 5-HT) and 5-hydroxyindole-3-acetic acid (5-HIAA) were decreased, while 5-hydroxytryptophol (5-HTOL) was increased. The levels of 5-HTOL/5-HIAA in urine samples of drinking suspects were greater than 1, in that of no drinking suspects were less than 1.

  • The purpose of this study was to identify the effects of gene expression of endoplasmic reticulum (ER) stress in skeletal muscle and adipose tissue on acute exhaustive exercise. Thirty-five Sparague Dawley male rats were divided into a control group (CON, n = 7) and a exhaustive exercise group (n = 28), immediately after exhaustive exercise group (n = 7), after 30 minutes exhaustive exercise group (n = 7), after 60 minutes exhaustive exercise group (n = 7), after 180 minutes exhaustive exercise group (n = 7). As a result, changes in the composition of the blood serum triglyceride concentration increased significantly in immediately after exhaustive exercise group, On the contrary, blood glucose showed a significantly decreased (p < .05). Homeostasis of energy metabolism due to exhaustive exercise as a result of the mechanism of action of skeletal muscle in the glycogenolysis and absorption, which indicates that the process of means. On the other hand, a result of examining changes in endoplasmic reticulum stress-related proteins in skeletal muscle and adipose tissue, JNK1 except in skeletal muscle BiP, ATF4, CHOP, GRP78 mRNA increased significantly immediately after exercise, and after 30 minutes returned to normal levels that could be confirmed (p < .05). BiP mRNA in adipose tissue show a similar pattern and skeletal muscle increased significantly immediately after exercise, but other changes in the specificity of the endoplasmic reticulum stress-related proteins also did not appear. In conclusion, Exercise applies and exercise training duration and exercise intensity as well as research on the interaction of the endoplasmic reticulum stress-related genes should be study continuously, to be more clear.

  • Plasma cholesterol is increased in normal aging in both rodents and humans. This is associated with reduced elimination of cholesterol and decreased receptor-mediated clearance of plasma low-density lipoprotein (LDL) cholesterol. The aims of this study were: (1) to determine age-related changes in plasma lipid profiles, and (2) to determine the effect of fenofibrate, an activator of peroxisome proliferator activated receptor alpha (PPAR $\alpha$), on plasma lipid profiles in normal rats on a standard diet. Male Sprague-Dawley (SD) rats (n=15) were fed standard chow and water from 10 to 25 weeks of age. During that period, we measured daily food intake, body weight, fasting and random blood glucose levels, plasma total cholesterol (TC), triglycerides (TG), and free fatty acid (FFA) levels. At 20 weeks of age, all rats were randomly divided into two groups: a fenofibrate group (in which rats were gavaged with 300 mg/kg/day of fenofibrate) and a control group (gavaged with water). Fenofibrate treatment lasted 5 weeks. There were no significant changes in daily food intake, blood glucose, and plasma TG level with age. Body weight, plasma TC, and FFA levels were significantly increased with age. Fenofibrate significantly decreased plasma concentrations of TC and FFA, which had been increased with age. However, fenofibrate did not influence the plasma concentration of TG, which had not increased with age. These results suggest that fenofibrate might have a novel role in preventing age-related hypercholesterolemia in SD rats on a normal diet.

  • Male Sprague-Bawler rats were blocked into four groups which were normal rats fed control diet (NC) diabetic rats fed control diet (DC), normal rats fed Hamcho powder diet (NH), and diabetic rats fed Hamcho powder diet (DH). Diabetes was induced by single injection of streptozotocin (60 mg/kg B.W. i.p.). The animals were fed ad libitum for 5 weeks. Malondialdehyde (MDA), glucose 6-phosphtase (Gspase), glutathione S-transferase (GST) glutathione Peroxidase (GPx), and glutathione reductase (GR) activities were measured in the homogenates of liver and kidney, and total lipid, total cholesterol, triglyceride, and HDL-cholesterol concentrations in the blood serum. Food and water intakes were markedly higher in diabetic groups than those of normal groups and were not significantly decreased by Hamcho powder supplementation, But, FER (Feed efficiency ratio) of DH Brood was higher than that of U group. Total cholesterol level of DH group was decreased in the second and third week, and the weekly change of blood sugar was also decreased in the 5th week. Dietary Hamcho intake showed 41.2% of hypoglycemic effect in diabetics rats. Levels of total lipid and triglycerides of DH group were lower than those of DC group. Hepatic GR activity of DH group was higher than those of other groups. However, renal GR activity was lower than those of other groups. Hepatic G6Pase activity was significantly high in DH group and reduced by Hamcho powder supplementation. GST was reduced by Hancho diet in diabetic rats. In conclusion Hamcho supplementation decreased serum lipid and glucose concentration in STZ-induced diabetic rats and this effects of Hamcho might exert antidiabetic effect of Hamcho powder diet.

  • Ten, first lactation, 87.5%HF dairy cattle were used to investigate effects of long-term administration of recombinant bovine somatotropin (rbST) on nutrient uptake by the mammary gland at different stages of lactation. Measurements of arterial plasma concentrations and arterial-venous differences of metabolites across the mammary gland were performed in combination with measurment of mammary blood flow to estimate the mammary uptake. Animals in experimental groups were injected subcutaneously every 14 days from day 60 of lactation with a prolonged-release formulation of 500 mg of rbST (POSILAC, Monsanto, USA) or with sterile sesame oil without rbST in the control group. During early lactation, the milk yield of rbST-treated animals was higher than that of the control animals (p<0.05). The peak milk yield in both groups of animals declined from the early period of lactation with progression to mid- and late-lactation. No significant changes were observed in the concentration of milk lactose, while the concentrations of milk protein significantly increased as lactation advanced to mid- and late-lactation in both groups. Milk fat concentrations were significantly higher in rbST-treated animals than in control animals, particularly in early lactation (p<0.05). Mammary blood flow (MBF) markedly increased during rbST administration and was maintained at a high level throughout lactation. The mean arterial plasma concentrations for glucose and acetate of rbST-treated animals were unchanged. The net mammary glucose uptake of rbST-treated animals increased approximately 20% during early lactation, while it significantly decreased (p<0.05), including the arteriovenous differences (A-V differences) and extraction ratio across the mammary gland, as lactation advanced to mid- and late-lactation. A-V differences, mammary extraction and mammary uptake for acetate increased during rbST administration and were significantly higher (p<0.05) than in the control animals in early and mid-lactation. Mean arterial plasma concentrations for ${\beta}$-hydroxybutyrate and free glycerol were unchanged throughout the experimental periods in both groups. A-V differences and extraction ratio of ${\beta}$-hydroxybutyrate across the mammary gland did not alter during rbST administration. Mean arterial plasma concentrations for free fatty acids ($C_{16}$ to $C_{18}$), but not for triacylglycerol, increased in rbST-treated animals and were significantly higher than in control animals during early lactation (p<0.01). These findings suggest that an increase in MBF during rbST administration would not be a major determinant in the mediation of nutrient delivery and uptake by the mammary gland for increased milk production. Local changes in biosynthetic capacity within the mammary gland would be a factor in the utilization of substrates resulting in the rate of decline in milk yield with advancing lactation.
