  • The experiment was conducted to compare the effects of supplements of copper, vitamin I and selenium on growth and immune responses of broiler chicks fed cornsoy diets. The basal diet contained 21% crude protein, 2,800 kcal ME, 10 mg Vitamin E, 10 mg copper and 0.1 mg selenium per kg diet. Additions of the basal diet were copper (150mg and 250 mg/kg) or combination of vitamin I(200 mg/kg) and selenium(2 mg/kg). Serum immunoglobulin G(IgG) concentrations and body weight gain were determined weekly from hatching to 7 weeks of age. Additions of copper(150mg, 250mg) to the basal diet were showed, at the four weeks of age, 4.8% and 4.5% higher in body weight gain than that of control group, respectively. The active immune system of copper and (Vit. E+Se) treated groups developed one week earlier than control group(basal diet). Negative correlation between IgG concentration and body weight gain was showed at the period from hatching to three weeks of age and, thereafter, positive correlation were identified (p<0.01). Mortality rates were observed lower in all treated groups than that of control. In conclusion, the lower the levels of serum IgG, at the first two weeks of age, the lower in disease Infection and the higher in body weight gain.

  • The purpose of this study was to investigate the influence of the additive chitosan on the storage characteristics and quality attributes of sponge cake. In addition to a control sample with no chitosan, sponge cake was prepared with the addition of various concentrations of chitosan (1,000, 2,000 and 3,000 ppm), and stored for 5 days at three temperatures ($5^{\circ}C$, $15^{\circ}C$ and $25^{\circ}C$). The control sample demonstrated considerable hardness compared to other samples containing chitosan regardless of storage temperature and period. The degree of retrogradation of the samples containing chitosan was higher than that of the control samples, with values under 30% regardless of the concentration of chitosan or storage condition. The total color variance(E) of the control sample and the samples with chitosan did not show a significant difference. The overall acceptability of the samples containing 1,000 ppm chitosan was similar to the control sample.

  • Cheonggukjang that was prepared with different concentrations of sea mustard [0% (control), 5% (SM5), 10% (SM10) and 15% (SM15)] were investigated. The pH of cheonggukjangs prepared with sea mustard was higher than that of control during fermentation for 72 hrs at $37^{\circ}C$. The total aerobes of the cheonggukjang variants reached 9.40 (control), 9.45 (SM5), 9.59 (SM10) and 9.59 (SM15) log CFU/g after fermentation for 72 hrs at $37^{\circ}C$. The amino nitrogen and viscocus substance contents of the cheonggukjang variants increased with fermentation time, SM5 showed the highest amino nitrogen content ($397.13{\mu}g/mL$) and viscocus substance content (6.53%) among various cheonggukjang after 72 hrs fermentation. The total polyphenol contents of various cheonggukjangs were increased with the sea mustard increased. The DPPH radical scavenging ability of the cheonggukjang variants were 68.09% (control), 77.91% (SM5), 80.72% (SM10) and 79.40% (SM15) and their ABTS radical scavenging ability were 86.66% (control), 89.01% (SM5), 91.32% (SM10) and 92.27% (SM15) after fermentation for 72 hrs. The sensory characteristics of the cheonggukjangs prepared with sea mustard showed higher than control in taste, flavor and overall acceptability but did not significantly differ.

  • To investigate the effects of Ewomia ulmoides olivon extract on the serum and hepatic lipid status and anti-oxidant enzyme activities, male Sprague Dawley (SD) rats were given high fat diets and Eucomia ulmoides olivon ethanol extracts for 6 weeks. Rats were divided into (our groups consisting the control (C), Eucomia ulmoides oliuon extract fed group (CE), high fat diet group (CL) and the extract and high fat fed group (CLE). Eucomia ulmoides oliuon ethanol extract lowered total cholesterol, but increased HDL-cholesterol and HDL-cholesterol/total cholesterol of the serum compared to the control. On the other hand, the ratio of HDL-cholesterol/total cho-lcsterol (HTR) was increased by 55% (p<0.05). High fat diet significantly increased serum cholesterol contents, but decreased HDL-cholesterol level and HTR (p<0.05). Atherogenic index (AI) of CL group was increased by almost four times of the control (p<0.05). Triglycerides (TG) and phospholipids were also increased by high fat diet. Eucomia ulmoides oliuon ethanol extract decreased the levels of TG (p<0.05) and phospholipids (p<0.05). Although liver antioxidant engyme activities including glutathione sulfur transferase (GST), superoxide dismutase (SOD) and catalase were decreased by high fat diet, those were stimulated by the administration of Eucommia ulmoides olivon ethanol extract.

  • To evaluate the antioxidative and antiaging effects of buchu in vivo system, 2% or 5% buchu diets were fed to ICR mice for 13 months and lipid peroxidation, protein oxidation, activities of antioxidative enzymes and total glutathione content on liver were measured. Hepatic TBARS contents did not show differences among diet groups, while buchu diet suppressed the protein oxidation significantly. SOD activities of control diet group decreased slowly after 7 month but buchu diet increased its activities steeply for first 3 month and continued to increase twice or three times higher than control diet during 13 month. While GSH-Px activities of control diet group were increased slightly with age, buchu diet increased its activities twice or three times higher than control. While catalase activities of control diet group were almost not changed with age, buchu diet increased its activities in both 2% and 5% diet groups. Total hepatic glutathione contents were gradually increased with age, while buchu diets In-creased its contents remarkably. According to this study, many antioxidative materials and sulfides compounds containing buchu seems to protect antioxidative systems on ICR mice.

  • This study was performed to investigate the quality characteristics of sponge cake made with leek(Allium tuberosum Rottler) powder. In order to evaluate the physical and sensory properties of different cake, the leek powder was added to wheat flour at various ratios(3, 5, 7, 9%, w/w). The specific gravity of bread dough tends to increase with the addition of leek powder. The moisture levels of the sponge cakes made with leek powder were higher than that of the control. Crumb color values, lightness(L) and redness(a) decreased by leek powder addition, while yellowness(b) was significantly increased (p<0.05). In texture analyses, hardness, cohesiveness, springiness and gumminess decreased with the addition of leek powder. In sensory evaluations, the 3% leek powder sponge cake showed higher sensory property scores than others(p<0.05).

  • This study was conducted to evaluate quality characteristics of white breads with Acanthopanax senticosus extract(ASE) (0, 25, 50, 75 and 100%). Addition of ASE significantly decreased L-value, and increased a and b-values. Compared with the control bread, specific volume of bread added with ASE was increased. The cohesiveness, springiness and gumminess of the breads added with ASE were higher than those of the control group. Also, a sensory evaluation was carried out in terms of acceptability(color, flavor, taste, texture and overall acceptability). Taken together, the 50% treatment ranked the highest evaluation values, as compared to other treaments. Accordingly, to improve the quality of bread, it is recommendable to add ASE to the 50% level in substitution for water in making a loaf of bread. After all, this study was to confirm the possibility of ASE's utilization as natural materials containing the functional substance.

  • This study was performed to investigate the effects of sources and levels of dietary fiber on lipid metabolism in rats. Male weanling rats of Sprague-Dawley were fed ad libitum a diet containing perctin or cellulose at 5%, 10% and 20% for 4 weeks. Rats fed pectin gained significantly less weight than rats fed cellulose. Feed efficiency ratio was decreased at 10% and 20% group rats of pectin compared to control rats. Pectin was effective in lowering liver cholesterol, total lipid and triglyceride content at all levels. Whereas the cellulose supplementation had no effect to reduce serum and liver lipids. Cellulose led to an accumulation of serum and liver cholesterol. The least accumulation of lipid was in fed a cholesterol free diet. It is likely that lipid metabolism is quite different between pectin and cellulose feeding.

  • The donor pool for heart transplants is severely limited and there is still a legal problem of brain death. This study assessed the function of hearts "absolute anoxic" for ten minutes after asphyxia by perfusing the hearts on a Langendorfr apparatus for 45 minutes with Krebs-Henseleit buffier at 37 t at 80 cm H2O. Forty isolated rat hearts were divided into four groups. Ten control hearts (group 1) were perfused on the circuit without intervening ischemia. Ten hearts (group 2) were harvested, quickly flushed with 5cc of cold University of Wisconsin solution, and stored in the same cold solution for 4 hours. Ten hearts (group 3) were excised, quickly flushed with 5 u of cold Stanford cardioplegic solution and stored in cold saline solution for 4 hours. Ten asphyxiated hearts (group 4) had warm ischemia for ten minutes and were perfused with 5u of cold Stanford cardioplegia containing 7,500 units of urokinase to dissolve intravascular clots, and stored in cold saline solution for 1.5 hours. Time of spontaneous defibrillation (TSD) after perfusion was significantly longer in group 2, group 3 and group 4 than in group 1. TSD in group 3 and group 4 was significantly longer in comparison to that of group 2. Left ventricular developed pressure(LVDP) at 15 minutes was significantly lower in group 3 and group 4 than in group 1 and group 2. In group 4, LVDP at 30 minutes and 45 minutes was significantly lower compared with that in group 1 . In conclusion, asphyxiated rat hear;ts which had absolute anoxia for 10 minutes after as hyxia showed relatively satisfactory cardiac function. function.

  • This study was conducted to investigate the effects of diet on the nutritional status and constipation rate of female college students. A total of 251 female college students living in Gyeonggi province participated in this study. Dietary intake was ascertained from a 3-day dietary record, including 2 weekdays and 1 weekend day. Anthropometrics, general characteristics, diet experiences, dietary habits and prevalence of constipation were analyzed using a questionnaire. The subjects were divided into two groups, a control group (n=165, 46.2%) and a diet group (n=135, 53.8%). There was no significant difference in age, height, weight or BMI between groups. The prevalence of constipation was higher in the diet group than the control group. The intakes of energy, dietary fiber and water of the diet group were significantly lower than those of the control group. Correlation analysis revealed that the prevalence of constipation was negatively associated with exercise score, dietary fiber intake and water intake. It is postulated that dietary habits might be important factors contributing to constipation. Accordingly, nutrition education aimed to improve intakes of fiber and water may be necessary during weight control periods.
