The effects of dipping syrups prepared with isomaltooligosaccharides on the characteristics of Yackwa were investigated. The dipping syrups were prepared replacing sucrose with 0, 25 and 50% isomaltooligosaccharide. Physical and sensory characteristics of Yackwa were evaluated. Isomaltooligosaccharides increased dehydration rate and increased absorption rate of dipping syrups. Yackwas dipping in the syrup containing isomaltooligosaccharides were more acceptable than those with sucrose syrup. The acceptability was significantly correlated with shinness(p<.01), moistness(p<.05), adhesiveness(p<.05), cohesiveness(p<.01), roasted taste(p<.0l) and sweetness(p<.05). Therefore, isomaltooligosaccharides might be a good alternative for sucrose in making dipping syrup of Yackwa.

This study investigated the metabolizable energy (ME) intake, net energy of production (NEp), heat production (HP), efficiencies of ME use for energy, lipid and protein retention as well as the performance of broiler chickens fed diets based on cassava chips or pellets with or without supplementation with an enzyme product containing xylanase, amylase, protease and phytase. The two products, cassava chips and pellets, were analysed for nutrient composition prior to feed formulation. The cassava chips and pellets contained 2.2% and 2.1% crude protein; 1.2% and 1.5% crude fat; and 75.1% and 67.8% starch, respectively. Lysine and methionine were 0.077%, 0.075%, and 0.017%, 0.020% protein material, respectively, while calculated ME was 12.6 and 11.7 MJ/kg, respectively. Feed intake to day 21 was lower (p<0.01) on the diet containing cassava chips compared to diets with cassava pellets. Enzyme supplementation increased (p<0.01) feed intake on all diets. Live weight at day 21 was significantly (p<0.01) reduced on the diet based on cassava chips compared to pellets, but an improvement (p<0.01) was noticed with the enzyme supplementation. Metabolizable energy intake was reduced (p<0.01) by both cassava chips and pellets, but was increased (p<0.01) on all diets by enzyme supplementation. The NEp was higher (p<0.01) in the maize-based diets than the diets containing cassava. Enzyme supplementation improved (p<0.01) NEp in all the diets. Heat production was highest (p<0.01) on diets containing cassava pellets than on cassava chips. It is possible to use cassava pellets in diets for broiler chickens at a level close to 50% of the diet to reduce cost of production, and the nutritive value of such diets can be improved through supplementation of enzyme products containing carbohydrases, protease, and phytase.

The effect of red ginseng ethanol extract on the immunotoxicity of diethylstilbestrol (DES) was studied in ICR mice. ICR male mice were divided into S groups (10 mice/group), and red ginseng ethanol extract (50, 100 and 200 mg/kg body wt., respectively) and DES (1 mg/kg body wt.) were injected intraperitoneally (i.p.) to ICR mice once a day for 2 weeks. Mice were sensitized and challenged with sheep red blood cells (S-RBC). Immune response were evaluated by humoral immunity, cell-mediated immunity, non-specific immunity, and circulating leukocyte counts. The results of this study were summarized as followings: 1. The DES-treated control group as compared with normal group showed the tendency to decrease body weight rate and relative liver weight, decreased both humoral and cellular immune responses, phagocyte activity, and circulating leukocyte counts, but increased the natural killer (NK) cell activity. 2. Compared with the DES-treated control group, DES plus red ginseng ethanol extract-treated groups significantly decreased the body weight rate (P<0.01). Relative liver weight was significantly decreased in DES plus red ginseng ethanol extract (50mg/kg)-treated group (P<0.01), but significantly increased in DES plus red ginseng ethanol extract (100mg/kg)-treated group (P<0.01). Relative spleen and thymus weights were significantly enhanced in DES plus red ginseng ethanol extract (100 mg/kg)-treated group (P<0.01), but significantly decreased in DES plus red ginseng ethanol extract (200 mg/kg)-treated group (P<0.01). 3. Both humoral and cellular immune responses were significantly decreased in DES plus red ginseng ethanol extract-treated groups rather than in the DES-treated control group (P<0.01). Especially, it weakened the decrease in DES plus red ginseng ethanol extract (100 mg/kg)-treated group. 4. Phagocyte activity and circulating leukocyte counts were significantly decreased in DES plus red ginseng ethanol extract-treated groups rather than in the DES-treated control group (P<0.01). Especially, it weakened the decrease in DES plus red ginseng ethanol extract (100 mg/kg)-treated group. NK cell activity was significantly enhanced in DES plus red ginseng ethanol extract (100 mg/kg)-treated group (P<0.01), but significantly decreased in DES plus red ginseng ethanol extract (50 and 200 mg/kg)-treated groups (P<0.01).

This study was aimed to investigate whether or not black soybean supplements affect levels of lipid profiles and female hormone (estradiol; E2, estrogen; Es) in 57 middle-aged women (in their 40s and 50s). All subjects were randomly assigned to the control or black soybean supplement group (BSS group). The BSS group was allocated to use dietary black soybean supplements (100 g/day) for 8 weeks. The BSS subjects were divided into two subgroups; 14 women were in the premenopausal group and 15 were in the postmenopausal group. We measured lipid profiles, female hormones and nutrient intakes at 0 weesk and 8 weeks. After 8 weeks, high-density lipoprotein (HDL) cholesterol was significantly decreased (P<0.01) and the athrogenic index (AI) was significantly increased (P<0.01) in control group. In BSS group, triglyceride (TG) (P<0.05), low-density lipoprotein (LDL) cholesterol (P<0.01) and LDL-HDL ratio (LHR) (P<0.01) were significantly decreased. However, E2 and Es were significantly increased (P<0.01). Compared to the control group, the BSS group revealed statistically significant improvements in the levels of TG, HDL-cholesterol, AI, LHR, E2 and Es (P<0.05). In the premenopausal group, HDL-cholesterol (P<0.05), E2 (P<0.01) and Es (P<0.05) were significantly increased and AI (P<0.01) and LHR (P<0.01) were significantly decreased after 8 weeks. In the postmenopausal group, E2 (P<0.05), and Es (P<0.05) were significantly decreased. However, total cholesterol (TC) was increased (P<0.01). Compared to the postmenopausal group, the premenopausal group was significantly improved on HDL-cholesterol, LDL-cholesterol and LHR (P<0.05). In conclusion, black soybean supplements may have beneficial effects on improving lipid profiles and female hormones.

A metabolism trial was conducted with 28 Najdi rams allocated into seven dietary groups to evaluate the effect of dietary inclusion of Salicornia bigelovii Torr biomass on nutrient digestibility, rumina I fluid metabolites and nitrogen and mineral balances. Either the stems (ST) or spikes (SP) of this seawater-irrigated halophyte were incorporated into complete diets at rates of 0, 10, 20 and 30% levels, replacing equal amounts of rhodesgrass hay in a ground mixed control diet. Digestibility of DM, OM, EE, NFE and fecal and urinary nitrogen were not affected by increased level of ST in the diet. As level of ST increased from 0 to 20% in the diets, CP digestibility and nitrogen retention approached their maximum (p<0.01), whereas CF digestibility reached its minimum (p<0.01). On the other hand, except for EE, digestion of all nutrients and nitrogen retention were linearly depressed (p<0.01) as SP increased in the diets from 10 to 30% level. Concentration of ammonia-N, total VFA and pH values in the rumen fluid were lower (p<0.01) with the ST- or SP-fed diets than with the control diet. Increasing level of ST or SP in the diet was associated with an increase (p<0.01) in the proportion of acetate and a decline (p<0.01) in molar percentage of propionate in the ruminal fluid. Sodium absorption increased (p<0.01) with increased ST and SP in the diets up to the 10 and 20% level, respectively, followed by constant absorption values up to the 30% level. When the level of ST in the diet gradually increased to 30%, a concomitant increased (p<0:01) in Ca and P absorption were obvious; whereas, increased level of SP in the diets from 0 to 30% resulted in noticeable (p<0.01) depression in Ca and P apparent absorption.

To develop the microbial agents for the environmentally-friendly treatment and recycling of food waste, useful microorganisms, which showed higher degradation activities to various organic compounds and possessed flocculating activities, were isolated from the earthworm. One of the isolated strains, named JS-01, was further selected due to its higher flocculating activity against 0.5% Kaolin clay. JS-01 was identified as Bacillus pumilus sp. by 16s rDNA analysis. The optimal temperature and pH for the growth of JS-01 to express the flocculating activity was found to be at $37^{\circ}C$ in pH 7.0 of EPS broth medium. JS-01 also expressed good degrading activity against cellulose, which is one of the representative organic materials in food waste. We propose that JS-01 will be a good candidate for the efficient treatment of food waste and leachate due to the property to degrade cellulose and flocculating activity.

For the production of Korea traditional cereal wine makgeolli, a rice fermentation starter nuruk was Rhizopus oryaze CCS01 commercial nuruk. The carbohydrate content of rice nuruk was higher, the levels of moisture, ash, crude protein, and crude fat were lower. In particular, the saccharifying activity of rice nuruk was 2.2 times higher than commercial nuruk. pH, alcohol, and viable yeast cells of makgeolli made rice nuruk were higher than those of makgeolli made commercial nuruk. In contrast, the levels of acidity, $^{\circ}Brix$, viable lactic acid bacteria (LAB) cells, and browning of makgeolli made rice nuruk were lower than those of makgeolli made commercial nuruk, the alcohol content of glutinous rice (GUR) makgeolli made rice nuruk higher other samples. These results suggest that rice nuruk R. oryzae CCS01 make new type cereal makgeolli.

The effect of cecal ligation on the utilization of dietary [15N]urea in chickens fed 5 % protein diet plus urea were investigated. Nitrogen balance and utilization tended (P<0.01) to increase by cecal ligation. Total uric acid excretion was significantly decrease by (P<0.01) cecal ligation in chickens from origin of diet and urea (P<0.01). Excretion of ammonia was increased in chickens from origin of diet, where as it decreased in chickens an urea diet (P<0.01). Amount of urea nitrogen excretion from origin of urea was significantly decrease (P<0.01) by cecal ligation, but cecal ligated chicken fed 5% protein diet with urea showed 51.6% urea utilization. Result obtained in present study indicates that ceca is having beneficial role for urea utilization in chicken fed protein deficient diets, but ceca do not always positive role for nitrogen utilization.
