The salt-fermented anchovy sauce (AS) was packed in round No. 307-1 can, and thermally processed at $121.1^{\circ}C$ to obtain Fo values of 3, 5 and 10. The changes of food components and qualifies by thermal processing of sterilized AS (RAS) were examined. The compositions of AS were as followed; pH 6.81, VBN 394.7 mg/100g, total nitrogen 2,195.5 mg%, amino-nitrogen 1,010.5 mg%, and acidity 10.5 ml. Viable cell counts of AS on 0%, 5%, 20% NaCl-medium were $2.9{\times}10^3,\;9.1{\times}10^3$ and not detected, respectively. And viable cell counts of RAS were not detected. Acidity, total nitrogen and amino nitrogen contents of AS decreased slightly with the severeness of heat treatments, whereas pH and VBN content were increased. Total free amino acid contents of raw AS and RAS were 12,802.5 mg% and $11,212.6{\sim}12,105.4\;mg%$, and major amino acids were alanine, glutamic acid, leucine, isoleucine, valine and lysine. Also contents of IMP, hypoxanthine, TMAO and TMA in AS and RAS were 42.1 mg% and $35.5{\sim}40.9\;mg%$, 103.7 mg% and $103.1{\sim}105.5\;mg%$, 78.8 mg% and $58.2{\sim}71.6\;mg%$, 55.8 mg% and $58.9{\sim}68.5\;mg%$ respectively. And a little changes were observed in whole volatile components of AS with severeness of heat treatments by GC chromatogram patterns. Judging from the chemical and sensory evaluations, the Fo 3 heat treatment sample was not inferior to raw AS, and maintained good quality for 1 year storage.

Three strains of lactic acid bacteria were isolated from fish and shrimp pickles. Two strains were identified as Lactobacillus casei, and one strain as L. Pentosus, respectively. All three strains were used as starters in producing yogurts. The physico-chemical characteristics of yogurts were examined. The original pH, titratable acidity, visicosity and viable cell counts of the yogurts were $4.03{\sim}4.26,\;1.049{\sim}l.217%,\;1,772{\sim}2,232\;cps\;and\;1.4{\times}10^9{\sim}1.6{\times}10^9\;cfu/ml$, respectively. In evaluating buffer capacity, $12.50{\sim}14.06\;ml$ 1.0N HCl was consumed to titrate 100 ml of yogurt to pH value 2 units below the original pH value and $9.46{\sim}13.06\;ml$ of 1.0N NaOH was consumed to pH value 4 units above the original pH value. The ${\beta}-galactosidase$ activity reached maximum at 48 hrs, and reduced gradually during fermantation. After 2 hr incubation of yogurts at $37^{\circ}C$ under different pH conditions, ${\beta}-galactosidase$ activities of three strains were reduced to 50% at pH 3.5, but there were no remaining activities neither at pH 2.5 nor at pH 1.5. Under the same pH conditions the number of viable cells decreased to $1.9{\times}10^6{\sim}1.8{\times}10^8\;cfu/ml$ at pH 2.5 and $1.0{\times}10^3{\sim}2.4{\times}10^5$ at pH 1.5, respectively. However, no significant difference was found at pH 3.5.

Objectives : Sinhyowoldo-san (SHWDS) is said to be a traditional medicine used for shigellosis, abdominal pain, diarrhea. But mechanism of SHWDS mediated-modulation of immune function is not sufficiently understood. To ascertain the molecular mechanisms of SHWDS 70% EtOH extract on pharmacological and biochemical actions in inflammation, we researched the effect of pro-inflammatory mediators in phorbol-12-myristate-13-acetate (PMA)+ A23187-activated human mast cell line (HMC-1). Methods : In the present research, cell viability was measured by MTS assay. pro-inflammatory cytokine production was measured by performing enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and western blot analysis to analyze the activation of mitogen-activated protein kinases (MAPKs), nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$). The investigation focused on whether SHWDS inhibited the expressions of interleukin-6 (IL-6), interleukin-8 (IL-8), MAPKs and $NF-{\kappa}B$ in PMA+A23187-activated HMC-1 cells. Results : SHWDS has no cytotoxicity at measured concentration (50, 100, and $250{\mu}g/ml$). SHWDS ($250{\mu}g/ml$) inhibits pro-inflammatory cytokine expression in PMA+ A23187-activated HMC-1 cells. Moreover, SHWDS inhibited cyclooxygenase (COX)-2 expression. In activated HMC-1 cells, SHWDS suppressed phosphorylation of extracellular signal-regulated kinase (ERK 1/2) and c-jun N-terminal Kinase (JNK 1/2). Then, SHWDS suppressed activation of nuclear factor $NF-{\kappa}B$ in nuclear, degradation of IkB ${\alpha}$ in cytoplasm. Conclusions : We propose that SHWDS has an anti-inflammatory therapeutic potential, which may result from inhibition of ERK 1/2, JNK 1/2 phosphorylation and $NF-{\kappa}B$ activation, thereby decreasing the expression of pro-inflammatory genes.

Purpose : Radiotherapy is effective in local treatment for retinoblastoma. However, asymmetric facial hypoplasia after radiation is a serious late effect. This study was performed to investigate the effects of enucleation and chemotherapy with or without radiotherapy in advanced intraocular and intraorbital retinoblastoma. Methods : Between 1985 October and 2006 December, the records of thirty five patients who were diagnosed as retinoblastoma at Yeungnam University Hospital were reviewed. Advanced intraocular and intraorbital retinoblastoma patients classified as Reese-Ellsworth group III, IV, and V and Grabowski- Abramson class II were selected for the study. Results : Eighteen patients were enrolled in this study. All patients were enucleated and had received chemotherapy. Nine patients received radiotherapy and nine patients didn't receive radiotherapy. Tumor cells were found on resection margin of optic nerve in five of nine patients who received radiotherapy, but none of nine who didn't receive radiotherapy. Chemotherapy included vincristine, adriamycin, cyclophosphamide, VM-26, cisplatin before 2001, and vincristine, etoposide, and carboplatin after 2001. There were no recurrences or metastases in nine patients who didn't receive radiotherapy. But two of nine patients who received radiotherapy had metastases to brain. However, all survivors who received radiotherapy had significant facial asymmetry. Conclusion : In advanced intraocular and intraorbital retinoblastoma without tumor cell on resection margin of optic nerve, enucleation and chemotherapy without local radiotherapy appears to be safe for long-term survival. However, in those with tumor cells on resection margin of optic nerve, enucleation and chemotherapy with local radiotherapy seems to be necessary to improve survival.

Sorghum bicolor L. is one of the important minor cereals in Asia, Africa, and the central United States, and it is considered a rich source of polyphenols, flavonoids, and dietary fiber. However, there is a lack of data on the anti-cancer activity of Sorghum in prostate cancer cells and immune activity in macrophages. This study aims to investigate the potential effects of an ethanol extract of S. bicolor L. (SE) on inducing apoptosis in RC-58T/h/SA#4 cells and immunomodulatory activity in RAW 264.7 cells. SE significantly inhibited the viability of RC-58T/h/SA#4 primary prostate cancer cells in a dose-dependent manner. The morphology of RC-58T/h/SA#4 cells treated with SE was shrunken and involved the formation of an apoptotic body and nuclear condensation. In addition, SE markedly activated caspase-8, -9, and -3; increased the protein levels of Bax, p53, cleaved PARP, and cytosolic cytochrome c; and decreased Bcl-2 protein expression. Furthermore, the inhibition of caspases in RC-58T/h/SA#4 cells with z-VAD-fmk attenuated SE-induced cell growth inhibition. The production of nitric oxide (NO) was also elevated by SE treatment, as revealed by immune response parameters. These results suggest that SE inhibits growth and induces apoptosis in primary human prostate cancer cells in a caspase-dependent manner, and it modulates the immune functions in macrophages. Therefore, Sorghum bicolor L. may be used as a functional food to prevent prostate cancer and enhance immune activity.

Scutellariae Radix (Scu.), one of the immune-regulatory substances, is recognized to play the role in the metabolic process of inflammation, allergy and immunity. It has been traditionally used in the Oriental medicine to treat inflammatory bowel diseases (IBD). The purpose of this study was to evaluate the effects of water extracts of Scutellariae Radix on the spleen lymphocyte immune function in the Balb/c female mice treated with dextran sodium sulfate (DSS) to induce colitis. Water extract of Scutellariae Radix (100 mg/kg) and sulfasalazine (50 mg/kg) were administrated orally for 2 weeks of experimental period. Mice were divided into three experimental groups randomly: DSS group (5％ DSS was ad libitum for 5 days) as control group, DSS ＋ Scu. (water extracts of Scutellariae Radix for 2 weeks after 5％ DSS was ad libitum for 5 days) as experimental group, and DSS ＋ Sulfasalazine group (Sulfasalazine for 2 weeks after 5％ DSS was ad libitum for 5 days) as positive control group. Levels of Ig A, Ig E, CD4$^{＋}$, CD8$^{＋}$, TNF-$\alpha$ and other cytokines were measured. Treatment of DSS for 5 days induced bowel inflammation and the treatment with Scu. water exteract and sulfasalazine significantly recovered the damage. The length of intestine of DSS group was significantly shorter than that of other groups. The serum and fecal concentration of Ig A of SS ＋ Scu group was higher than those of DSS group. The contents of CD4$^{＋}$ T cells was higher in the DSS ＋ Scu. group than the other groups and CD8$^{＋}$ T cells was the lowest in DSS ＋ Sulfasalazine group. The Ig A level of cultured supernatant of spleen lymphocyte was the highest, while the Ig E level was the lowest in SS ＋ Scu group. The concentration of TNF-$\alpha$, cytokine secreted from the Th1 cell in the supernatant spleen lymphocyte, was the highest in the DSS group and the lowest in the DSS ＋ Scu. group. The concentration of IFN-${\gamma}$ and ll...-12 was lower in the DSS ＋ Scu. group than those of the other groups. The concentration of IL-4 in the supernatant of spleen lymphocyte was the lowest in the DSS ＋ Scu. group but IL-10 was not significantly different. Based on these findings, water extract of Scutellariae Radix exhibited the inhibitory effect via IL-4 production thereby inhibited the production of Ig E and strengthened immune system, and alleviated injury in DSS- induced colitis mice model.

II-Ⅵ ZnO compound semiconductor thin films were grown on $\alpha$-Al$_2$O$_3$(0001) single crystal substrate by radical beam assisted molecular beam epitaxy and the optical properties were investigated. Zn(6N) was evaporated using Knudsen cell and O radical was assisted at the partial pressure of 1$\times$10$^{4}$ Torr and radical beam source of 250-450 W RF power. In $\theta$-2$\theta$ x-ray diffraction analysis, ZnO thin film with 500 nm thickness showed only ZnO(0002)and ZnO(0004) peaks is believed to be well grown along c-axis orientation. Photoluminescence (PL) measurement using He-Cd ($\lambda$=325 nm) laser is obtained in the temperature range of 9 K-300 K. At 9 K and 300 K, only near band edge (NBE) is observed and the FWHM's of PL peak of the ZnO deposited at 450 RF power are 45 meV and 145 meV respectively. From no observation of any weak deep level peak even at room temperature PL, the ZnO grains are regarded to contain very low defect density and impurity to cause the deep-level defects. The peak position of free exciton showed slightly red-shift as temperature was increased, and from this result the binding energy of free exciton can be experimentally determined as much as $58\pm$0.5 meV, which is very closed to that of ZnO bulk. By van der Pauw 4-point probe measurement, the grown ZnO is proved to be n-type with the electron concentration($n_{e}$ ) $1.69$\times$10^{18}$$cm^3$, mobility($\mu$) $-12.3\textrm{cm}^2$/Vㆍs, and resistivity($\rho$) 0.30 $\Omega$$\cdot$cm.

Grifola umbellatus was extracted using methanol, and the extract was further fractionated by water and ethyl acetate. Assay of each fraction with MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium-bromide] revealed significant cytotoxicity effect of the methanol extract of Grifola umbellatus against human gastric cancer cell but not normal human lymphocytes. The methanol extract showed the highest antioxidant activity as well. Antimicrobial activity of Grifola umbellants against Helicobacter pylori was higher in method extract than in other fractions. Grifola umbellatus had a significant inhibitory effect on Helicobacter pylori reducing both its growth and urease activity. These results show that the methanol extract of Grifola umbellatus possesses therapeutic potential on gastric diseases.

Korean ginseng(Panax ginseng C.A. Meyer) is very difficult to obtain stable production of qualified ginseng roots because of variable stresses in soil environments. In transformation of ginseng with betain aldehyde dehydrogenase gene, compounds synthesized for controlling osmotic pressure such as proline, glycine, betaine, polyols and sugar were accumulated in cell for salt resistance in transgenic plants. 2 Agrobactgerium conjugants were acquired with bet A and bet B genes for solt resistant plants. A. tumefaciens MP90/pBetA and A. tumefaciens MP90/pBetB were recombined for increasing the tolerance to salt stress. To confirm the transformation of the binary vector, tobacco plant was transformed, and the transformant can grow on media containing high concentration of kanamycin. To identify NPT 11, BetA and BetB genes of the transformants, the band on the agarose was confirmed by PCR and RT-PCR techniques. The transformants of ginseng with bet A and bet B genes were acquired on the phytohormone free basic MS media containing only antibiotics and 1M mannitol used for selection of transgenic plant, but the transfomation efficiency for BetA and BetB was very low.
