  • To observe the effect of the different level of PUFA and marginal tocopherol supplement on HDL-chol, tissue tocopherol content and fatty acid composition, the rats were supplied either safflower oil or conconut oil with or without tocopherol supplement to the experimental diet. Plasma tocopherol level was not greatly influenced by the different dietary fat and similar effect was observed in the liver but not in the adipose tissue. HDL-chol level was reduced in the high PUFA diet regardless of tocopherol content. No effect by tocopherol supplement was observed in the fatty acid composition of liver and adipose tissue lipid in both dietary PUFA levels . There was also no increase in the content of tissue polyenoid acid by tocopherol in the high PUFA diet . Fatty acid composition of tissue lipid was rather more influenced by dietary fat. Lauric and myristic acid contents were higher in the low PUFA diet and linoleic acd and total polynoic acid content were higher in the high PUFA diet. With tocopherol supplement tocopherol /PUFA ratio of tissue was increased but the ratio of high PUFA diet was significantly lower than that of low PUFA diet. Marginal tocopherol supplement could not reduce the peroxidizability index of high PUFA diet.

  • The present study was carried out to investigate the effects of magnesium supplement levels and periods on calcium, magnesium, and phosphorus metabolism in male Sprague-Dawley rats given low protein and magnesium deficient diets for 2 weeks. Serum calcium content was significantly lower in the magnesium supplement group than in the magnesium-deficient group, but calcium excretion in urine and feces was significantly increased as magnesium level and period was increased. Increasing the dietary magnesium level and periods raised serum content and excretion of magnesium in urine k feces. Urinary excretion of phosphorus in two week group was significantly lower in the magnesium supplement group than in the magnesium-deficient group. fecal phosphorus excretion in supplement group (Mg 800mg/kg diet) was significantly higher than that of other group.

  • The aim of the present study was to assess the anti-obesity effects of fermented kochujang supplement in C57BL/6J mice. Thirty mice were divided into 3 groups; normal diet control group (ND), high fat diet control group (HD), and high fat diet plus kochujang supplemented group (HDK). Results were as follows: 1. Fennented kochujang supplement in high fat diet decreased body weight and epidydimal and back fat weight compared to non-supplement in HD group. 2. Lipid content and blood glucose level were lower in HDK group than HD group. 3. Fermented kochujang supplement increased mRNA level of lipolytic genes such as acyl-CoA synthetase (ACS), carnitine palmitoyltransferase-1 (CPT-1), and uncoupling proteins-1 (UCP-1) expression, whereas decreased mRNA level of adipogenic genes such as acetyl CoA carboxylase (ACC) expression. These findings suggest that fermented kochujang supplement in high fat diet normalized body weight, epididymal and back fat weight, lipid content, and blood glucose levels through controlling lipid metabolism and provides basic information on the control of obesity.

  • The effects of vitamin E supplement on 15%(w/w diet) perilla or corn oils were studied in rat hepatocellular chemical carcinogenesis induced by modified Solt & Farber model, which consists of 20mg/kg body weight diethylintrosamine(DEN) injection, 3 weeks feeding of 0.02%2-acetylaminofluorene(2-AAF) and partial hepatectomy. The area of placental glutathione S-transferase(GST-P) positive foci tended to be smaller in perilla oil group had lower thiobarbituric acid reactive substances(TBARS) CONTENT. Fatty acid compositions in microsomal membrane were reflected by dietary fatty acid compositions, and not affected by carcinogen treatment or vitamin E supplement. By vitamin E supplement, linolenic acid contents of perilla oil group were much increased. By carcinogen treatment, membrane stability decreased significantly in corn oil, but maintained in perilla oil groups Vitamin E supplemental effect was noticed only in the corn-carcinogen group. Perilla oil may prevent hepatocarcinogenesis by maintaining membrane stability and by reducing cytochrome P-450 content. Vitamin E supplement did not seem to have the effect on hepatocarcinogenesis, but prevented lipid peroxidation, reduced cytochrome P-450 content and maintained membrane stability.

  • It is difficult for mobile learners to maintain a high level of concentration when learning content for more than an hour while they are on the move. Despite the attention span issue, many m-learning systems still provide their mobile learners with the same content once used in e-learning systems. This has called for an investigation to identify the suitable characteristics of the m-learning environment. With this in mind, we have conducted a survey in hopes of determining the requirements for developing more suitable m-learning content. Based on the results of the survey, we have developed a content model comprised of two types: a segment type and a supplement type. In addition, we have implemented a prototype system of the content model for Apple iPhones and Android smartphones in order to investigate a feasibility study of the model application.

  • Immunopotentiating activity of water extract of Lycii Fructus, Rubus Fructus, Torilis Fructus, Schizandrae Fructus and Cuscutae Semen were investigated using mouse fed with normal diet and protein deficient diet. Body weight, ratio of spleen or thymus to body weight, number of total peritoneal exudate cell, content of total serum protein and albumin content were decreased in the mouse fed with protein deficient diets as compared to the mouse fed with normal diet. Regardless of the nutritional condition, the supplement of the water extract of Lycii, Rubus Torilis, Schizandrae Fructus or Cuscutae Semen increased the ratio of spleen to body weight. The increment of this ratio was significant by the supplement of water extracts of Lycii and Torilis Fructus in mouse fed with protein deficient diet. The supplement of water extracts of Torilis Fructus to the mouse fed with protein deficient diet increased the content of total serum protein and albumin content significantly. Similar results were obtained with Lycii, Rubus, Schizandrae Fructus and Cuscutae Similar. The electrophorogram shows the difference in the concentration of some serum protein constituents between the mouse fed with normal diet and protein deficient diet.

  • The thymus weight of the mouse was 54.1% in protein malnutritive diet group and 39.2% in group treated with saponin fraction of Panax ginseng in comparison to normal diet group. This decreasing effects of protein malnutritive diet and saponin fraction on the thymus weight practically disappeared after four weeks. The saponin fraction showed no effect on the spleen weight of the mouse. The supplement of the saponin fraction enhanced total peritoneal exudate cells, content of total serum protein and albumin content of the mouse, each 45, 8 and 10% respectively in comparision to that of normal diet group. And these values in protein malnutritive diet group were 61.2, 83.6 and 87.0% respectively in comparision to that of normal diet group, and recovered to the level of normal diet group by the supplement of the saponin fraction. The electrophoregram of the serum protein of the mouse fed with protein malnutritive diet was different from that of the mouse fed with normal diet, but this difference practically disappeared by the supplement of the saponin fraction.

  • A study was conducted to assess the nutritive value of two diets based on a low-energy variety of wheat, RAC C1 and their effects on intestinal mucosal structure and function in broiler chickens. The diets were fed with or without microbial enzyme supplement to male and female broiler chickens. The digesta viscosity was reduced (p<0.001) through supplementation with a microbial enzyme in male and female chicks. Enzyme supplementation also improved the dietary apparent metabolizable energy content (p<0.001) and had slight but non-significant positive effects on chick growth and feed conversion ratio. Intestinal mucosal structure and enzyme function were not affected by microbial enzyme supplement. Male chicks consumed more feeds (p<0.001), attained higher final body weight (p<0.001) and were more efficient at feed utilization (p<0.01) than the female chicks. Except for duodenal villus surface area and ileal protein content, intestinal mucosal structure and enzyme activities were similar between the two sexes and dietary treatment groups. The study showed an improvement in the nutritive value of the diets in the presence of the microbial enzyme supplement.

  • The objective of this study was to evaluate the effects of supplements with different crude protein (CP) contents on grazing cattle intake, digestibility, ruminal fermentation pattern, and nitrogen (N) metabolism characteristics during the rainy season. Five ruminal and abomasal cannulated Holstein${\times}$Zebu steers (296 kg body weight, BW) were used in a $5{\times}5$ Latin square design. The animals grazed five signal grass paddocks (0.34 ha). The five treatments evaluated were: Control (no supplement) and 1.0 g of supplement/kg BW with 0, 330, 660, and 1,000 g of CP/kg as-fed. The supplement was composed of starch, soybean meal, urea, and ammonium sulphate. There was a positive linear effect ($p{\leq}0.033$) of the CP content in the supplements on the organic matter (OM), CP, and digested OM intakes. The provision of supplements did not increase ($p{\geq}0.158$), on average, total and ruminal digestibilities of OM and CP. However, the increase in CP content in the supplements caused a positive linear effect ($p{\leq}0.018$) on ruminal digestibilities of OM and CP. Additionally, a quadratic effect of the CP contents of the supplements were observed (p = 0.041) for the ruminal digestibility of neutral detergent fiber corrected for ash and protein, with the highest estimate obtained with the CP content of 670 g/kg. The supply of supplements increased (p<0.001) the ruminal ammonia N concentration, which also changed linearly and positively (p<0.001) according to increase in CP content in the supplements. The apparent N balance and relative N balance (g/g N intake) were not, on average, changed ($p{\geq}0.164$) by the supplements supply. However, both showed a tendency of a linear increase ($p{\leq}0.099$) with increasing supplement CP content. The supplements increased (p = 0.007) microbial N production in the rumen, which also changed linearly and positively (p = 0.016) with increasing supplement CP content. In conclusion, protein supplementation in grazing cattle during the rainy season, while stimulating voluntary forage intake, results in higher efficiency of N utilization when compared to energy supplementation. This is a possible response to increased microbial protein synthesis in the rumen and improved N status in the animal body.
