The present study was designed to investigate whether ethanol extracts of Sophora flavescens (GS), Glycyrrhiza uralensis (GC), Dictamnus dasycarpus (BSP), and their mixtures (GGB-1, -2, -3, and -4) inhibit 1-chloro-2,4-dinitrobenzene (DNCB)-induced atopic dermatitis (AD) in a mouse model. DNCB was topically applied on the dorsal surface of Balb/c mice to induce AD-like skin lesions. The pathological phenotypes of AD, such as erythema, ear thickness, edema, scabs, and discharge, were significantly decreased in the GGB (DNCB + GS:GC:BSP = 3:1:1 mixture)-1-treated groups compared with the other treated groups. The weight of the spleen in immune organs was significantly decreased in the GGB-1-treated groups, whereas the weight of the liver in a control group was similar to that of the groups treated with the samples. Furthermore, toluidine blue staining analysis, a method used to specifically identify mast cells, showed that master cell infiltration into the dermis of the GGB-1-treated group was significantly decreased. The immunoglobulin E concentration was lower in the GGB-1-treated group. In addition, the levels of inflammatory cytokines (interferon-${\gamma}$, interleukin-1, 4, 5, 6, and 13, $1{\beta}$, and tumor necrosis factor-${\alpha}$) were also significantly reduced in the GGB-1-treated group. Taken together, these results suggest that a mixture of GS, GC, and BSP in a proportion of 3:1:1 (GGB-1) may contribute to the relief of AD symptoms and may be considered an excellent candidate for an AD therapeutic drug.
Some properties of cellulase and xylanase produced from Pleurotus ostreatus 301 and Lentinus edodes 3-1 during its growth in rice straw medium were investigated. The cellulase activities of P. ostreatus 301 and L. edodes 3-1 were increased in proportion to substrate concentration within 0.6% and 0.8%, respectively, and xylanase activities of two strains were increased within 1%. The reducing sugar production of cellulase and xylanase in two strains were proportionaly increased until 30 min. and 60 min. respectively. The opium pH for cellulase activities of P. ostreatus 301 and L. edodes 3-1 were pH 4.0 and pH 4.5, respectively, and xylanase activities of two strains were pH 5.0. The stable pH range for cellulase activities of P. ostreatus 301 was within 4.0 to 6.0 and L. edodes 3-1 was within 3.0 to 5.0, Xylanase activities of P. ostreatus 301 was within 4.5 to 6.0 and L. edodes 3-1 was within 3.5 to 6.0. The optium temperature for cellulase activities of P. ostraeatus 301 and L. edodes 3-1 were $40^{\circ}C$ and $50^{\circ}C$, respectively, but xylanase activities of P. ostreatus 301 and L. edodes 3-1 were $50^{\circ}C$ and $45^{\circ}C$, respectively. Thermal stability of enzymes were below of optimum temperature and these were mostly inactivate at $70^{\circ}C$ for 10 min of the metalic ions tested, cellulase activities of L. edodes 3-1 was increased by $Co^{++},\; Mg^{++}$ at the concentration of $10^{-2}M$, but were greatly inhibited by $Hg^{++},\;Cu^{++}$ in two strains. Xylanase activities were increased by $Ca^{++},\;Co^{++},\;Mg^{++}$ and $Cd^{++}$ but was greatly inhibited by $Hg^{++}$.

Genistein, an isoflavone in soybean products, is a potential chemopreventive agent against various types of cancer. There are several studies documenting molecular alterations leading to cell cycle arrest at G2/M phase and induction of apoptosis; however, its mechanism of action and its molecular targets on the prostaglandin $E_2$ ($PGE_2$) production and telomere length regulation in human cancer remain unclear. In this study, we investigated the effect of genistein on the levels of cyclooxygenases (COXs) and telomere regulatory components of several human cancer cell lines (T24, human bladder carcinoma cells; U937, human leukemic cells; AGS, human stomach adenocarcinoma cells and SK-MEL-2, human skin melanoma cells). Genistein treatment resulted in the inhibition of cancer cell proliferation in a concentration-dependent manner. It was found that genistein treatment markedly decreased the levels of COX-2 mRNA and protein expression without significant changes in the expression of COX-1, which was correlated with a decrease in $PGE_2$ synthesis. Genistein treatment also partly inhibited the levels of human telomerase reverse transcriptase (hTERT) as well as human telomerase RNA (hTR) and telomerase-associated protein (TEP)-1, and the activity of telomerase. Taken together, these findings provide important new insights into the possible molecular mechanisms of the anti-cancer activity of genistein.
The present study was conducted to evaluate the effects of fermented soybean meal (FSBM) on the level of cortisol hormone and immune-related serum proteins in weaned calves after experimentally induced lipopolysaccharide (LPS) challenge. Holstein neonatal calves (n = 21; 8 males and 13 females, BW = $42.2{\pm}6.15$ kg) were randomly allocated to one of two dietary treatments: SBM (control calf starter having soybean meal (SBM) as a main protein source) and FSBM (substitute SBM in control diet with FSBM) groups. All calves were fed milk replacer using an automatic milk-feeder according to step-down milking method and weaned at 7 weeks old. Experimental diets were given to calves ad libitum throughout the experimental period. For LPS challenge, all calves except negative control animals given phosphate buffered saline (PBS), were injected subcutaneously with Salmonella typhimurium LPS on day 7 (D7) after weaning (D0). No significant difference in growth performance and milk intake was observed between SBM and FSBM calves. Feeding FSBM diet resulted in significantly (p<0.05) higher LPS-specific IgG at D12 and D19 and LPS-specific IgA at D19 in peripheral blood. Calves fed with FSBM diet also had significantly (p<0.05) higher concentration of serum haptoglobin (Hp) at D8. Overall concentration of cortisol in FSBM group was considerably lower than that of SBM group. Results from current study indicate that FSBM may provide beneficial effects in alleviating weaning stress and enhance immune status of weaned calves.

The impact of free cyanide ($CN^-$) and thiocyanate ($SCN^-$) on the $CN^-$ (CDO) and $SCN^-$ degraders (TDO) to nitrify and denitrify aerobically was evaluated under alkaline conditions. The CDO's were able to nitrify under cyanogenic conditions, achieving $NH_4{^+}-N$ removal rates above 1.66 mg $NH_4{^+}-N.L^{-1}.h^{-1}$, except when $CN^-$ and $SCN^-$ loading was 15 mg $CN^-/L$ and 50 mg $SCN^-.L^{-1}$, respectively, which slightly inhibited nitrification. The TDO's were able to achieve a nitrification rate of 1.59 mg $NH_4{^+}-N.L^{-1}.h^{-1}$ in the absence of both $CN^-$ and $SCN^-$, while the presence of $CN^-$ and $SCN^-$ was inhibitory, with a nitrification rates of 1.14 mg $NH_4{^+}-N.L^{-1}.h^{-1}$. The CDO's and TDO's were able to denitrify aerobically, with the CDO's obtaining $NO_3{^-}-N$ removal rates above 0.67 mg $NO_3{^-}-N.L^{-1}.h^{-1}$, irrespective of the tested $CN^-$ and $SCN^-$ concentration range. Denitrification by the TDO's was inhibited by $CN^-$, achieving a removal rate of 0.46 mg $NO_3{^-}-N.L^{-1}.h^{-1}$ and 0.22 mg $NO_3{^-}-N.L^{-1}.h^{-1}$ when $CN^-$ concentration was 10 and 15 mg $CN^-.L^{-1}$, respectively. However, when the CDO's and TDO's were co-cultured, the nitrification and aerobic denitrification removal rates were 1.78 mg $NH_4{^+}-N.L^{-1}.h^{-1}$ and 0.63 mg $NO_3{^-}-N.L^{-1}.h^{-1}$ irrespective of $CN^-$ and $SCN^-$ concentrations.
Physicochemical properties of Youngia sonchifolia were compared according to harvesting time and brine methods for its Kimchi preparation. Moisture contents in the roots and the leaves of Y. sonchifolia grown for 5 weeks was more than those grown for 11 weeks. 5-week-grown Y. sonchifolia contained more total free sugar than 11-week-grown ones, and among total free sugar the content of fructose was the most, and the contents of glucose and sucrose were rather high. The roots of 11-week-grown Youngia sonchifolia were harder than those of 5-week grown ones. When the roots were soaked in NaCl solution, the hardness decreased with time. Salt concentration of the Kimchi of Y. sonchifolia increased by the brined material of the Kimchi with soaking time.Salt concentration of the Kimchi was higher in the leaves than in the roots.The roots and leaves of Y.sonchifolia grown for 11 weeks contained organic acids such as malic acid, oxalic acid, succinic acid,lactic acid, and citric acid,among which major organic acids were malic acid, oxalic acid, succinic acid, whereas lactic acid and citric acid were minor organic acids.

The effective extraction methods and chemical components of crude polysaccharides of ascidian tunics were investigated. Tow extraction conditions, autoclaving or enzyme treatment, were applied. The proximate composition of ascidian tunics was not much different between those dried in raw (containing pigments) and those acetone treated and dried (decolorized), showing $50\%$ of carbohydrate and $40\%$ of protein. It was possible to extract up to $10\%$ of crude polysaccharides from ascidian tunics regardless of the extraction methods, autoclaving or enzyme treatment. In case of the latter the extraction yield by neutrase was higher than that with alkalase (Novo co.) or mixture 2000 (Pacific chemical co.). The most effective enzyme concentration and extraction time appeared to be 24 hrs of extraction with $3\%$ neutrase. On the other hand, in autoclave treatment, 6 hrs extraction showed most desirable extraction yield, about $9.7\%$. The compositions of amino acid of decolorized ascidian tunic (acetone treated group) and the crude polysaccharide from the autoclaving (water solubles) or neutrase treatment (enzyme digestibles) were similar to each other. Histidine was the highest both in the neutrase and autoclave treatment group and the yield were $29.2\%,\;20.4\%$, respectively, followed by aspartic acid and glutamic acid. Among the minerals, the content of Ca was significantly high, followed by Mg and Na.
Purpose: Hepatitis B is infection caused by Hepatitis B virus (HBV). Currently, there are several methods, Kits and equipments for conducting Hepatitis B test. Due to ununiformed methods, it would cause some differences. To manage these differences, it needs process evaluating function of test system and reagent using particular standard substance. The aim of this study is to investigate tendency of RIA method's reagent used in Asan Medical Center through comparing several other test reagents using national standard substance. Materials and Methods: The standard substance in National Institute of Food and Drug Safety Evaluation's biology medicine consists of 5 things, 4 antigens and 1 antibody. We tested reagents using A, B company's Kits according to each test method. All tests are measured repeatedly to obtain accurate results. Results: Test result of "HBs Ag Mixed titer Performance panel" is obtained match rate compared S/CO unit standard with RIA method and EIA 3 reagents, CIA 2 reagents is that company A's reagent is 94.4% (17/18), 83.3% (15/18), B is 88.9% (16/18), 77.8% (14/18). Test result of "HBs Ag Low titer Performance panel" is obtain that EIA 2 reagents is shown 7 posive results, CIA 3 reagents is 11, and RIA method's company A's reagent is 3, B is 2 of 13 in low panel. "HBV surface antigen 86.76 IU/vial" tested dilution. A is obtain positive results to 600 times(0.14 IU/mL), B is 300 times (0.29 IU/mL). Case of "HBV human immunoglobulin 95.45 IU/vial", A is shown positive result to 10,000 times (9.5 mIU/mL) and B is 4,000 times (24 mIU/mL). Test result of "HBs Ag Working Standards 0.02~11.52 IU/mL" is shown that Company A's kit concentration level was 0.38IU/mL, company B was 2.23 IU/mL and higher level of concentration was positive results. Conclusion: When comparing various test reagents and RIA method according to National Standard substances for Hepatitis B test, we recognized that there were no significant trends between reagents. For hepatitis B virus antigen-antibody titers even in parts of the test up to 600 times the antigen, antibodies to 10,000 times the maximum positive results could be obtained. Therefore, we confirmed that results from Asan Medical Center are performed smoothly by reagents and system for hepatitis B virus test.
The main goal of this study was to produce transgenic piglets by the method of injection of sperm-mediated exogenous DNA. Spermatozoa (1$\times$106 sperm of final concentration) obtained from caudal epididymis were mixed with pBC1-hEPO (20 ng/${mu}ell$) or pcDNA3 LAC Z (20 ng/${mu}ell$), and followed by electroporation (500 V, 25 ㎌). Matured oocytes having the first polar body and dense cytoplasm were selected and centrifuged at 12,000g for 6 min. After sperm injection, the oocytes were activated electrically (1.7 ㎸/cm, 30 $\mu$ sec, single pulse) in 0.3 M mannitol solution. Eggs injected sperm were cultured in NCSU 23 medium (0.4% BSA) at 39$^{\circ}C$, 5% $CO_2$ in air for 192 h. This study were comprised 3 experiments. Experiment 1 compared the developmental efficiencies between the sperm-injected oocytes (Group 1) and further activated electrically (Group 2). Experiment 2 compared the expression of pcDNA3 LAC Z in the embryos produced by Group 1 and Group 2. Finally, experiment 3 carried out transfer of embryos (1-8 cell stage) transfected with pBC1 -hEPO into surrogate recipients synchronized by injection of combination of PG600 with hCG. The rates of cleavage and development into blastocyst stage in Group 2 were significantly higher than those of Group 1 (71.3% and 28.1% vs. 43.3% and 10.3%, respectively, p<0.05). Thirty (24.2%) out of 124 embryos analyzed in Group 2 were positive by X-gal. Similarly, in Group 1, 16.3% (8/49) were positive. After transfer of 789 embryos to 7 recipient gilts, three out of them examined by ultrasound became pregnant. One recipient is in day 50 pregnancy. On day 54 of gestation, two were carried out uterotomy in order to confirm the pregnancy One had 7 and another had 2 fetuses. We conclude that injection of sperm-mediated gene transfer will be used as a valuable tool for the production of transgenic piglets.
A total of 629 Duroc${\times}$Landrace${\times}$Large White crossbred pigs were utilized in three experiments (Exp. 1, 222 pigs weighing $25.6{\pm}2.0\;kg$ BW; Exp. 2, 216 pigs weighing 5$6.2{\pm}4.3\;kg$ BW; Exp. 3, 191 pigs weighing $86.4{\pm}4.6\;kg$ BW) conducted to determine the effects of fermented potato pulp on performance, nutrient digestibility, carcass traits and plasma parameters in growingfinishing pigs. Each experiment lasted 28 d. The pigs were assigned to one of two corn-soybean meal-based diets containing 0 or 5% fermented potato pulp. The inclusion of fermented potato pulp increased weight gain (p<0.05) in experiments 1 and 2 and increased feed intake (p<0.05) in experiment 2. Feed conversion was improved (p<0.05) in experiment 2 and showed a tendency to improve (p<0.10) in experiments 1 and 3 when pigs were fed fermented potato pulp. Fermented potato pulp increased (p<0.05) dry matter digestibility in experiments 1 and 3 and energy digestibility in experiment 2. Feeding fermented potato pulp decreased plasma urea nitrogen (p<0.05) and alanine aminotransferase (p<0.05) in experiments 1 and 2, while plasma aspartate aminotransferase was decreased (p<0.05) in experiment 3. Dietary fermented potato pulp did not affect the carcass characteristics of finishing pigs. Feeding fermented potato pulp reduced (p<0.05) fecal ammonia concentration in all three experiments. In conclusion, feeding growing-finishing pigs diets containing 5% fermented potato pulp improved weight gain and feed conversion without any detrimental effects on carcass traits. The improvements in pig performance appeared to be mediated by improvements in nutrient digestibility.
