This study was conducted to develop a topping formula for pizza containing Chungkukjang and onion as the main ingredients. The maximum amount of onion was limited to 10.5%, since the pizza crust and toppings would separate if too much water dispelled from the onion tissue during baking. The Chungkukjang was substituted for Bulgoggi, a meat topping. The sensory acceptability scores for the pizza topping decreased as the amount of Chungkukjang increased from 3.6% to 7.3%, due to its unpleasant odor, but scores increased when 1.6% Kimchi powder was added to the Chungkukjang without a significant difference from the control. Thus favorable sensory quality was obtained with a topping formula containing 8.7% Chungkukjang, 10.5% onion, and 1.6% Kimchi powder. The nutrient values of the final pizza products were assessed as follows. By adding the Chungkukjang and onion, crude protein, crude lipid, crude ash, and total dietary fiber contents increased. Moreover, the calorie level of the Chungkukjang-onion pizza was 3.8% higher than that of the control pizza. The amounts of compound amino acids including lysine increased. The free amino acids also increased from 143.3 to 188.6 mg/100 g. The ratio of saturated fatty acids to unsaturated fatty acids changed from 1:0.71 to 1:0.81. For the consumer test, the age groups of the participants were classified as 15-29 years old, 30-39 years old, and 40-62 years old. A positive result on acceptability of the developed pizza was obtained from most of the panelists in all age groups. Over 93% of the 119 responding subjects had purchasing intentions. An, especially, strong purchaging intention was shown in the younger age group of 15-29 year-olds, even though they had a lower preference for the Chungkukjang. Finally, an attribute of satisfaction was induced based on 'health' (79.5%) and 'flavor' (15.7%).

The chemical properties and physiological activities of the freeze-dried stromata of Cordyceps militaris were examined. A proximate analysis exhibited that the stromata consisted mainly of crude carbohydrate (74.3%), crude protein (11.5%), and moisture content (8.7%), with a low content of crude ash (4.%) and fat (1.3%). The carbohydrate was mostly composed of glucose (88.6%). A large quantity of essential fatty acids, including linolenic acid (33.8%) was also observed. An analysis of the component amino acid showed a relatively high ratio of the essential amino acids, lysine (101.2 mg/g), methionine (62.7 mg/g), and acidic amino acids of glutamic aicd (57.5 mg/g) and aspartic acid (43.9 mg/g), whereas a low of tyrosine content (4.7 mg/g). An examination of the cordycepin content indicated tht the stromata and mycelium-embedded media (silkworm pupae) contained 0.2% and 0.5%, respectively. From the examination of the physiological activities, based on methanol extract (M), ethylacetate extract (EA), and hot-water extract (HW) fractions of the stromata, the hot-water extract (HW) fraction showed the most potent intestinal immune modulating activity, anticoagulant activity, and anticomplementary activity, whereas the ethylacetate extract (EA) fraction exhihited a radical scavenging activity. Therefore, the results from the present study indicate that the stromata of C. militaris contain various healthy chemical ingredients, and that especially boiled water extract of whole body would apprear to provide beneficial physiological activities.

During the preparation of decoction from the mixture of Coptidis Rhizoma and Scutellariae Radix, insoluble copreciptate was formed. The coprecipitated product (COP) was composed of berberine and baicalin which was the active ingredient of Coptidis Rhizoma and Scutellariae Radix, respectively. COP was slightly soluble in water and could not be well absorbed after oral administration. This poor bioavailibility might be associated with its poor aqueous solubility. With the purpose of increasing the solubility and bioavailibility of COP, hydrolysis of COP by ${\beta}-glucuronidase$ was carried out. Hydrolyzed products (HOP) of COP were identified and assayed for active ingredients. The partition coefficient study, in situ absorption test, and pharmacokinetic study after oral administration were also performed. COP was found to be consisted of berberine and baicalin with molecular ratio of 1 to 1. This compound was hydrolyzed to berberine and baicalin by ${\beta}-glucuronidase$. The rate of hydrolysis was higher at higher temperature up to $50^{\circ}C$ and higher concentration of ${\beta}-glucuronidase$ up to 2500 unit under our experimental conditions. Baicalein, which is more liphophilic than baicalin, showed greater absorption in small intestine than baicalin did. The plasma concentrations of berberine and baicalein after oral administration of HOP were significantly higer than those of COP. The possible mechanism of increased bioavailibility of berberine and baicalein could be the hydrolysis of COP by ${\beta}-glucuronidase$. On the basis of the above results, it might be said that HOP should be a suitable preparation for increasing the bioavailibility of Coptidis Rhizoma and Scutellariae Radix.

We conducted an 8-week feeding trial to evaluate dietary lipid sources on the growth performance and body composition of juvenile river puffer fish Takifugu obscurus. Nine experimental diets were formulated with fishmeal as the major protein ingredients, providing 50% crude protein. The experimental diets contained either beef fallow (BF), soybean oil (SO), rapeseed oil (RO), or linseed oil (LO). Each of these diets was then supplemented or not with 0.5% n-3 HUFA (BFH, SOH, ROH, and LOH), resulting in a total of eight experimental diets. The control diet contained fish oil (FO) as the lipid source. Fish averaging $10.3{\pm}0.03g$ were fed the experimental diets in randomly selected triplicate groups for 8 weeks. Weight gain and feeding efficiency of fish fed the FO and SOH diets were significantly higher than those of fish fed BF or RO (P<0.05), but these diets did not differ significantly from the other diets. The protein efficiency ratio of fish fed the SOH diet was significantly higher than that of fish fed the BF, SO, or RO diets (P<0.05), but these were not significantly different from the other diets. The specific growth rate of fish fed the FO and SOH diets was significantly higher than that of fish fed the BF diet (P<0.05). Whole body DHA and n-3 HUFA contents of fish fed the FO diet were significantly higher than those of fish fed the SO, RO, or LO diets (P<0.05), but were not significantly different from the other diets. These results indicate that soybean oil and linseed oil could replace up to 100% of fish oil in the diet containing 60% fishmeal for river puffer fish.

The aim of this study was to evaluate the effect of two diets different in crude fibre content and ingredients on performance and on caecal characteristics of rabbits around weaning. Thirty litters from thirty New Zealand White does were divided at Day 18 in two groups fed, respectively, a low fibre concentrate (LFC, consisting mainly of soybean meal, delactated whey, barley) from Day 18-28 followed by a creep feed (CF, consisting mainly in alfalfa meal, barley and wheat bran) from Day 29-32, and a CF from Day 18-32. After weaning (32 days) both groups were fed the CF ad libitum for two weeks. During the pre-weaning period, mortality, milk intake and solid feed intake (from Day 20) were recorded daily, while the live weight of kits was recorded twice, at 18 and 32 days. At day 28, one rabbit/litter was slaughtered in order to obtain data on caecal content characteristics. After weaning, the rabbits were located in collective cages, feeding ad libitum CF; feed intake, live weight and mortality were recorded weekly for two weeks. During the preweaning period, there were no differences between the groups in milk and solid feed intake and, by consequence, in live weight at weaning; instead, the mortality was higher (12.5 vs 4.5%) for the group (A) that changed diet at 28 days. Group A showed also a higher caecal pH (6.12 vs. 5.72), propionate to butyrate ratio (0.73 vs. 0.46), ammonia content (9.3 vs. 7.1 mmol/l), but a lower total volatile fatty acid content (66.8 vs. 82.1 mmol/l) than B Group, probably due to the dried milk whey in the concentrate. After weaning, there were no significant differences between the two groups. The authors concluded that the use of a low fibre concentrate for suckling rabbits is not recommended.

Effects of a supplemental fermented agro by-products diet on growth performance, blood characteristics and carcass traits were investigated in fattening pigs. The fermented diet mainly contained 38.0% brewer's grain, 25.0% rice bran and 21.0% byproduct of king oyster mushrooms. The mixed ingredients were fermented at $40^{\circ}C$ for 7 days and fed to crossbred barrow pigs for 62 days. Ninety pigs were housed in 10 head per pen with three replicate pens per treatment. The pigs in the control group were fed with formula feed, while the pigs in T1 group were fed 20, 40, 60, 80 and 100% fermented diet substituted with formula feed on 1 week interval. Pigs in T2 group were fed 30, 60 and 100% fermented diet substituted with formula feed on 1 week interval. The fermented diet significantly (p<0.05) decreased body weight gain and feed efficiency of pigs. The blood characteristics differed with diet types. Carcass grade was significantly better (p<0.05) in the pigs fed fermented diet than in the pigs fed control diet as well as ratio of high grade was higher in the fermented diet groups. Therefore, although a dietary of fermented diet decreased growth performance and feed efficiency, it improved the carcass grade in pigs.

This study is to enhance drug penetration via skin and investigate anti-inflammation effect following adoption of ultrasound. For this goal gel containing triamcinolone was prepared and the skin penetration rate and the change effects of blood plasma ingredients and serum enzyme were investigated. Using Franz type diffusion cell and the skin of hairless mouse, the permeation enhancing effect of ultrasound was tested. After the injury by direct trauma, the blood test was performed by measuring WBC, lymphocyte, and neutrophyl, and by analyzing CPK and LDH. The ultrasound transducer whose technical specification is geometric area(GA) $1.4\;cm^2$, effective radiation area(ERA) $0.8\;cm^2$, and beam non-uniformity ratio(BNR) 6.0 max was used. The influence of frequency having an effect on skin permeation rate was higher in the case of using 1MHz and continuous treatment. The temperature of receptor phase was not influenced in skin permeation by phonophoresis. Skin permeation increase attended by intensity of ultrasound, the permeation of triamcinolone was accelerated at $2.5\;w/cm^2\;than\;1.0\;w/cm^2$. Following muscle injury phonophoretic group the number of WBC, neutrophil and lympholyte were decreased significantly as compared with both control group and ultrasound group. The result of variation of serum CPK and LDH activity conformed to the phonophoretic effect as same pattern with the variation of WBC, neutrophil and lymphocyte.

The effects of processing and frozen storage conditions on the quality of anchovy Engraulis japonica fried surimi gels were investigated. Protein content decreased after surimi gel processing from 19.6% (raw meat) to 12.1% (kamaboko) due to the added ingredients and change in water content. Lipid content decreased from 2.8% (raw meat) to 1.3% in minced and 0.5% in surimi, but fried kamaboko showed a 6.9 % lipid level. Thiobarbituric acid values and thiobarbituric acid reactive substances levels were highest in kamaboko samples, 89.5 and 1.9 mg/g solid, and increased gradually with storage time to 101.8 and 4.6 mg/g solid, respectively. In vitro protein digestibility increased from 79.2% in raw anchovy to 88.5% in kamaboko samples. Levels of trypsin inhibitor decreased gradually with processing and during storage time from 2.43 in raw anchovy to 0.31 mg/g solid in the kamaboko sample after 60 days of frozen storage. No noticeable changes in total essential amino acid was observed during processing conditions. Computed protein efficiency ratio for kamaboko was highest (2.59) compared with whole anchovy (1.96), minced (1.94) and surimi (2.50). Fresh fried anchovy kamaboko showed similar values of hardness, springiness, gumminess and chewiness to commercial surimi gel, but a higher values were seen for fracturability and adhesiveness, and lower values for cohesiveness and resilience. The frozen and thawed anchovy kamaboko showed higher values for all of these rheological parameters compared with fresh and commercial kamaboko. Anchovy kamaboko showed the lowest lightness (62.9) and redness (0.16) and similar yellowness (11.9) compared with commercial kamaboko. Frozen storage and vacuum packaging were effective maintaining the shelf life of anchovy kamaboko within 30 days, but were not effective after 45 days due to fat oxidation.

Current drying and encapsulation methods for probiotics manufacturing are complicate and cost-burdened processes. The aim of this study was to develop a simple ingredient mixture to make probiotic granules via one-step process, providing not only a cryoprotective effect during freezing and drying but also high survival ratio in gastrointestinal tract. As cryoprotectans, commercially available ingredients including skim milk, monosaccharide (trehalose or glycerin), maltodextrins (with low or high degree of equivalents) were used. Their cryoprotective effect during lyophilization and survival ratios in artificial gastric juice and bile salt were measured against 3 strains of lactic acid bacteria (LAB) (Lactobacillus plantarum, Lb. brevis, and Lactococcus lactis). As results, 3 mixtures with different compositions showed a cryprotective effect on LAB tested and the best compostion was dependant upon LAB; skim milk 10%, trehalose 15%, glycerin 0.5%, and NaCl 1% was for Lb. plantarum and Lc. lactis, and maltodextrin 10% instead of skim milk was for Lb. brevis. In addition, those mixtures showed similar survival effect on LAB tested. These results demonstrate that skim milk or maltodextrins with trehalose, glycerin, and NACl can be effectively used for onestep lyophilization of LAB as an alternative method of encapsulation.

This study was conducted to evaluate the possible utilization of 5 different animal protein sources in juvenile rainbow trout, Oncorhynchus mykiss. Meat and bone meal (MBM), feather meal (FM), squid liver powder (SLP), poultry by-product(PBP) and blood meal (BM) were chosen to be the candidate for the possible ingredients for the dietary fish meal replacer in rainbow trout feed. Six different diets were formulated of isonitrogenous and isocaloric basis of $48\textperthousand$ crude protein and 16.7 kJ/g diet: diet 1, $100\textperthousand$ white fish meal (WFM); diet w, $80\textperthousand$ WFM +20% MBM; diet 3, 80% WFM +20% FM; diet 4, 80% WFM+20% SLP; diet 5, 80% SFM+20% PBP; diet 6, 80% WFM +20% BM. As the dietary protein sources, each diet containing 34.7% of animal protein were supplied by WFM with and without MBM, FM, SLP, PBP or BM and approximately 64.2% of plant protein. After one week of conditioning period, fish averaging 2g were divided into six groups and fed one of the experimental diets for 8 weeks. After eight weeks of feeding trials, there were no significant differences in weight gain and feed conversion ratio among groups of fish fed diet 1, 3, 4, 5 and 6(P>0.05). However, weight gain of fish fed diet 2 were significantly lower than those of fish fed diet 1, 3, 4, 5 and 6(P<0.05). These results indicated that FM, SLP, PBP and BM can be used as a dietary fish meal replacer up to 20% in juvenile rainbow trout.
