  • This study was conducted to evaluate the effect of regular exercise and other relating factors on the activities of erythrocyte antioxidant enzymes and plasma total radical-trapping antioxidant potential (TRAP) in 61 healthy male college students. The study population were divided in two groups ; small amount of exerciser (exorcise time less than 30min/d) and moderate amount of exerciser (exorcise time more than 30min/d) according to their physical exercise habits measured by a questionnaire. Dietary intake of vitamin C and vitamin E, Plasma lipid Profiles, erythrocyte superoxide dismutase(SOD), glutathione peroxidase(GSH-Px) and catalase activities, as well as plasma TRAP levels were determined. Plasma TRAP level was significantly higher in moderate amount of exercisers than that in small amount of exercisers. No significant differences were observed in erythrocryte SOD, catalase and GSH-Px between the two groups. Mean exercise time was positively correlated with the plasma level of TRAP significantly, and amount of alcohol consumption was negatively correlated with the erythrocyte SOD activity, Dietary vitamin C and I intakes did not correlated with either erythrocyte enzyme activities or plasma TRAP levels. There were positive correlations between plasma HDL-cholesterol, and erythrocyte GSH-Px or plasma TRAP levels. Plasma vitamin C concentrations was negatively correlated with plasma TRAP levels and erythrocyte SOD activity, however plasma vitamin C concentration was positively correlated with erythrocyte GSH-Px activity, The results would suggest that regular moderate exercise, nonsmoking, high HDL-cholesterol and high plasma vitamin E concentration enhance antioxidant defences against reactive oxygen species and may increase the likelihood of a healthier life span.

  • Fermented Chlorella vulgaris CBT$^{(R)}$ was evaluated for its effects on egg production, egg quality, liver lipids and intestinal microflora in laying hens. One hundred and eight Hy-line Brown layers (n = 108), 80 wk of age, were fed a basal diet supplemented with CBT$^{(R)}$ at the level of 0, 1,000 or 2,000 mg/kg, respectively for 42 d. Egg production was measured daily and egg quality was measured every two weeks. Five eggs from each replicate were collected randomly to determine egg quality. Egg production increased linearly with increasing levels of CBT$^{(R)}$ supplementation (p<0.05), although there was no significant effect of treatment on feed intake. Egg yolk color (p<0.001) and Haugh unit (p<0.01) improved linearly with increasing dietary CBT$^{(R)}$. Hepatic triacylglycerol level was linearly decreased with increasing dietary CBT$^{(R)}$ (p<0.05). The supplemental CBT$^{(R)}$ resulted in linear (p<0.001) and quadratic (p<0.01) response in population of cecal lactic acid bacteria. In conclusion, fermented Chlorella vulgaris supplemented to laying hen diets improved egg production, egg yolk color, Haugh unit and positively affected the contents of hepatic triacylglycerol and the profiles of cecal microflora.

  • This study was conducted to determine the optimum amount of dried Alaska Pollock Therage chalcogramma roe (D-AP-R) for preparing garlic gochujang with D-AP-R. We investigated the optimal preparation of garlic gochujang with D-AP-R by proximate composition, taste, color, and odor measurements and sensory evaluation. The moisture, ash contents and water activity of garlic gochujang with D-AP-R decreased as the amount of D-AP-R increased, whereas other components, such as crude protein and lipid contents, taste value, yellowness of Hunter color, and odor intensity, increased as D-AP-R increased. According to the sensory evaluation results, garlic gochujangs with 10 and 15% D-AP-R were superior to garlic gochujang without D-AP-R (control) in terms of taste and overall acceptance but inferior in terms of fish odor. However, there was no difference in the sensual color of garlic gochujang with versus without D-AP-R. These results suggest that high quality garlic gochujang can be prepared by adding 10% D-AP-R. The total amino acid content of garlic gochujang with 10% D-AP-R was 11.81 mg/100 g, which was higher than that of the control (9.05 mg/100 g). The cholesterol content of garlic gochujang with 10% D-AP-R was 16.1 mg/100 g, which is below the acceptable daily cholesterol intake (300 mg/day).

  • Semisulospira libertine (SL) has been used as a folk medicine for quenching a thirst, hepatic fever and inflammation in oriental countries. Although SL has been anecdotally ascertained to ameliorate the hepatic diseases, there are no sufficient experimental evidences. The purpose of this study was to examine the effect of Bitam-S, in which SL is a main component, on non-alcoholic fatty liver disease manifested in C57BL/6J ob/ob mice. At 6 week old, the ob/ob mice were randomly divided into four groups; control and three treatment groups. The control mice was to receive a regular diet, and the treatment groups were fed a regular diet with either 250mg/kg, 500mg/kg of Bitam-S (BS250 and BS500) or 300mg/kg of metformin (MT300) for a 8-week period. Bitam-S exerted beneficial effects on lipid homeostasis in ob/ob mice that are not necessarily due to its ability to decrease food intake but its specific effects on hepatic lipogenesis related genes (SREBP1a, FAS and SCD-1). The combined effects of Bitam-S to reduce body weight and lipogenic gene expressions, and reduce the deposition of triglyceride in the liver are indicative of a marked improvement in obesity-related non-alcoholic fatty liver disease. Taken together, Bitam-S has potential as a treatment agent for non-alcoholic fatty liver disease and deserves clinical trial in the near future.

  • To investigate the effect of Feelch on alcohol metabolism, we measured both blood alcohol concentration in human and hepatic alcohol metabolizing enzyme activity in rats. The blood alcohol concentration in Feelch-ingested group was significantly lower than that in water-ingested group at 0, 40, and 80 minute after alcohol intake. The blood alcohol concentration between male and female taken 300ml of $21\%$ alcohol showed the significant differences; the peak value of blood alcohol concentration in male and female were $0.083\pm0.014\%\;and\;0.108\pm0.018\%$, respectively. In alcohol-fed rats, aldehyde dehydrogenase (ALDH) activity was significantly increased, whereas alcohol dehydrogenase (ADH) activity was not changed. In both Feelch-fed group and Feelch plus alcohol-fed group, ADH and ALDH activity were significantly increased as compared with each control group. Feelch decreased phospholipase $A_2$ activity and lipid peroxidation in hepatic tissue and activities of serum aminotransferases as compared with control. These results suggest that Feelch may have a hepatoprotective effects and this is likely due to lower blood alcohol concentration via the increment of hepatic ADH and ALDH activity.

  • Objectives : This study was designed to protect effect on atherosclerosis through regulation of low density lipoprotein(LDL) by 70 % ethanol extract Ganoderma lucidum (GL) in LDL receptor knockout mouse (LDLr ko mice) fed Western diet.Methods : The LDLr ko mice were divided into 3 groups ; Control, GL100, and GL300. After grouping, LDLr ko mice were fed Western diet. The GL (100 or 300 mg/kg body weight/day, p.o.) was administered every day for 8 weeks. The body weight and food intake were measured every day. The changes in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, triglyceride (TG), total cholesterol (TC), and high-density lipoprotein (HDL) in serum were analyzed after experiment.Results : The LDLr ko mice fed Western diet were increased body weight gain and blood biochemistry parameters such as ALT, AST, TG, TC, and LDL. However GL300 group significantly reduced the body weight. Also TG, TC, and LDL level did not increase. The levels of ALT, AST, HDL were not changed. Also, LDLr ko mice model liver were observed lipid drop, but GL groups did not appear. Futhermore, histological analysis of GL groups aorta tissue were similar to NOR groups.Conclusions : We confirmed that whether GL administration is protect atherosclerosis or not. As the results, blood biochemistry and histological analysis did not changed much in GL administration groups. This study provides scientific evidence that GL protect the atherosclerosis through the reduction of LDL cholesterol. Therefore GL has potential medicine inhibition of atherosclerosis.

  • Objective : Obesity is often defined as a condition associated with accumulations of excessive body fats which resulting from disorder of energy balance in term of energy intake and energy expenditure. Methods : The effects of natural mixture (T) for inhibition of lipid metabolism on the liver, epididymal fat pads and pancreatic zymogen granules of high fat diet (HFD) supplied rats were observed by histopathology and histomorphometry. Results : As results of HFD supply, severe steatohepatitis such as increases of mean diameters of hepatocytes and the percentages regions of fatty changes was detected. In addition, hypertrophy of adipocytes (increase of mean diameters of epididymal fat pads) was also detected with dramatic decreases of pancreatic zymogen granules at histopathological and histomorphometrical observations. However, theses steatohepatitis and hypertrophy of adipocytes induced by HFD supply were inhibited by treatment of 5 % and 10 % T (T5, T10), respectively. Well corresponded as the results of adipocyte hypertrophy and steatohepatitis, the decreases of pancreatic zymogen granules were also dose-dependently inhibited by T treatment as compared with HFD control, respectively. Conclusion : In conclusion, based on the results, it is considered that test materials, T5 and T10, will be showed hepatoprotective and anti-obese effects, may be directly and/or indirectly mediated by pancreatic zymogen granules because they dose-dependently inhibited steatohepatitis, hypertrophy of adipocytes and decreases of pancreatic zymogen granules induced by HFD supply, respectively.

  • This study was conducted to determine if supplementation with a compound composed of caffeine (50 mg), capsaicin (75 mg), sesamine (30 mg), L-carnitine (300 mg), banaba (50 mg) and lotus (10 mg) enhanced human autonomic nervous activities (ANS) associated with thermogenic sympathetic activity and fat utilization. Ten healthy college males (21.2$\pm$1.0 yr) volunteered for this experiment. Autonomic nervous activities associated with energy metabolism were examined at 30 min intervals for a total of 120-min while at rest and every 5-min during exercise at 50% of the ventilation threshold before and after intake of the compound or placebo with 100 ml of water for 10 days. In addition, heart rate variability power spectral analysis was used to assess human autonomic nervous activities. The results indicated that there were no significant differences in heart rate during rest and exercise among trials. Furthermore, the autonomic nervous activity tended to increase after 10-days of consumption of the test compounds during the experimental period, but the differences did not reach statistical significance. However, before and after the compound test trial there was a significantly higher respiratory gas exchange ratio (rest 0: 0.83$\pm$0.01 vs. rest 3: 0.89$\pm$0.02, p<0.05), carbohydrate oxidation (CHO) rate (rest 0: 44.57$\pm$5.83 vs. rest 2: 63.86$\pm$5.91%, p<0.05) and a lower fat oxidation rate (rest 0: 55.43$\pm$5.83 vs. rest 2: 36.14$\pm$5.91%, p<0.05. In conclusion, the results of the present study suggested that the compound composed of caffeine, capsaicin, sesamine, L-carnitine, banaba and lotus components that was evaluated in this study did not induce a significant increase in human autonomic nervous activities or lipolysis, even though the individual components have been reported to induce increased fat oxidation.

  • This paper examines the effects of dietary polyunsaturated fatty acid/saturated fatty acid (p/s) ratios and butylated hydroxytoluene (BHT) on the hepatic microsomaI mixed-function oxidase sy. stem in 2~acetylaminofiuorene (2-AAF) treated rats. Sprague-Dawley male rats were fed the diet of beef tallow (p/s 0.08), beef tallow plus soybean oil (p/s 1.0), and soybean oil (p/s 4.0) at the level of 15%fat and with or without 0.3% BHT. After 2-AAF was injected twice at the ages of 23 and 27 weeks, cholesterol/phospholipid molar ratio, thiobarbituric acid reactive substances (TBARS) level, cytochrome P450, cytochrome $b_5$, NADPH-cytochrome $b_5$, and NADPH-cytochrome c reductase activity were measured from isolated hepatic microsomal fractions. In the beef tallow (p/s 0.08) and beef tallow plus soybean oil (p/s 1.0) groups, cholesterol/phospholipid molar ratio showed decreasing tendency by 2-AAF and BHT. Cytochrome P-450 content was decreased in the group of soybean oil (p/s 4.0) and NADPH-cytochrome c reductase activity was increased by 2-AAF and BHT in all the dietary groups. While TBARS levels were increased by 2-AAF in all the dietary groups, they were reduced by BHT in the soybean oil (p/s 4.0) group. These results suggest that long term intake of soybean oil (p/s 4.0) diet induced changes in the nature of microsomal membrane and induced less cytochrome P-450, low level feeding of BHT increased cytochrome c reductase activity and lowered microsomal lipid peroxidation levels, which were increased by 2-AAF treatment.

  • his study was conducted to determine the effect of dietary garlic supplementation on the growing performance and activity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase in broiler chicks from 3 to 5 wk post hatching. Fifty chicks were divided into 5 groups with 10 replicates per treatment and placed in a wire battery cage. Five levels of dietary garlic(0, 0.1, 0.3, 0.6 and 1.0%) were provided in an one way analysis. Feed and water were given ad libitum. Feed intake, weight gain and feed conversion rate(FCR) were not affected by the garlic supplementations. The HMG-CoA reductase activity decreased significantly(P<0.05) with the supplementation of garlic powder, compared to the garlic free group. As the dietary garlic level was increased, chicks showed decreased lipid contents in liver and blood serum. The results of this study indicate that blood cholesterol of chicks fed garlic supplemented diet might be reduced by inhibition of RMG-CoA reductase activity.
