Two kinds of Korean rice-wine (Yakju) with different process and ingredients, and Japanese rice-wine (Sake) were chosen for this study, and throughly dried and solubilized in water or cell culture medium. In vitro cytotoxicity assays of the solubilized wine solids exhibited that maximum dilution factors for inhibition of B 16BL6 mouse melanoma cell growth were 16X for herbal medicine-added rice-wine (Korean rice-wine I) and typical Korean rice-wine (Korean rice-wine II), and 8X for Japanese rice-wine. Their cytotoxic effects on HRT18 human colon adenocarcinoma cells were even lower than those on B16BL6 cells. The morphology of the tumor cells were changed by addition of the solubilized wine solids. Inhibitory effect of the rice-wine on in vivo tumor growth and metastasis were monitored after implantation of B16BL6 cells into C57BL/6 mice with daily feeding the solubilized wine solids. Compared to non-fed control groups, B16BL6 tumor growth and metastasis to lung were clearly inhibited by feeding the wine solids, in order of Korean rice-wine I > Korean rice-wine II > Japanese rice-wine. The data of in vitro cytotoxicity and the cell shape changes indicate that the inhibitory effect of tumor progression may be attributed to tumor cell differentiation or immune stimulation induced by certain components in the rice-wine, rather than direct cytotoxicity of the components.

The stability of surrounding rock will be poor when the tunnel is excavated through nearly horizontal stratum. In this paper, the instability mechanism of local nearly horizontal stratum in super-large section and deep buried tunnel is revealed by the analysis of the macro failure and micro fracture. A structural model is proposed to explain the mechanics of surrounding rock collapse under the action of stress redistribution and shed light on the macroscopic analytical approach of the stability of surrounding rock. Then, some highly effective formulas applied in the tunnel engineering are developed according to the theory of mixed-mode micro fracture. And well-documented field case is made to demonstrate the effectiveness and accuracy of the proposed analytical methods of mixed-mode fracture. Meanwhile, in order to make the more accurate judgment about yield failure of rock mass, a series of comprehensive failure criteria are formed. In addition, the relationship between the nonlinear failure criterion and $K_I$ and $K_{II}$ of micro fracture is established to make the surrounding rock failure criterion more comprehensive and accurate. Further, the influence of the parameters related to the tension-shear mixed-mode fracture and compression-shear mixed-mode fracture on the propagation of rock crack is analyzed. Results show that ${\sigma}_3$ changes linearly with the change of ${\sigma}_1$. And the change rate is related to ${\beta}$, angle between the cracks and ${\sigma}_1$. The proposed simple analytical approach is economical and efficient, and suitable for the analysis of local nearly horizontal stratum in super-large section and deep buried tunnel.

In order to investigate the immunomodulational effects of Lonicerae Caulis et Folium, the author measured cytokines production(IL-10, IL-12(P35), IL12(P40), $IFN-{\gamma}$) in mice splenocytes. The results were obtained as follows : 1. The water extract of Lonicerae Caulis et Folium significantly enhanced the gene expression of IL-12(P35), IL-12(P40), but reduced the gene expression of IL-10, $IFN-{\gamma}$. 2. In water fraction and ethyl acetate fraction, the gene expression of IL-12(P35), $IFN-{\gamma}$ was significantly increased and that of IL-12(P40), IL-10 was decreased. The above results demonstrate that Lonicerae Caulis et Folium has enhancing immune activity by upregulation of these cytokines. Therefore, if we make the relationship between these cytokines(IL-10, IL-12, $IFN-{\gamma}$) besides IL-1, IL-4, IL-6, $TNF-{\alpha}$, IL-8, $TGF-{\beta}$ and so on which concerned the immunopotentiation, the immunopotentiational mechanism of Lonicerae Caulis et Folium will be shown clearly.

Objective: Eosinophils are typically characterized by a bilobar nucleus with highly condensed chromatin and cytoplasm containing two major types of granules, specific and primary granules, and lipid bodies. The role of inflammation in asthma and other allergic diseases of the airways is widely appreciated, and airway inflammation is now included as a defining feature of asthma. The importance of the presence of eosinophils in the airways of patients with fetal asthma has long been recognized, but the mechanism by which these cells are recruited and retained in the lungs are only now being elucidated. Eotaxin is a potent and specific eosinophil chemoattractant that is mobilized in the respiratory epithelium after allergic stimulation. Methods : Water extracts of Armeniacae Amarum Semen(AAS) and pulmonary epithelial cell lines A549(alveolar typeII epithelial cells) and human eosinophils were used. Cytotoxic effects of AAS and MIS assay were estimated, as well as the effects of AAS on chemokines from prestimulated A549 cells by sandwich ELISA and RI-PCR. Chemotaxis assay was conducted on prestimulated eosinophils treated with AAS. Results : In this study it is demonstrated that $TGF-{\alpha}$, IL-4 and $IL-1{\beta}$ induced the accumulation of chemokine mRNAs in the alveolar epithelial cell lines A549 in dose-dependent manner. Eotaxin and IL-8 were inhibited by AAS in dose-dependent manner(p<0.05). Eosinophil migration was inhibited at high concentrations of AAS(p<0.05). Conculusions : These findings are indicative of suppression of eotaxin and IL-8, and suggest that this is accomplished through AAS treatment. This raises the possibility that AAS is of therapeutic value in diseases such as asthma.

The present experiment aimed to evaluate the effect of HMBi on the production performance and metabolism in dairy cows. Thirty multiparous Holstein dairy cows under similar conditions were randomly assigned to three dietary treatments; i) Control, a basal diet; ii) T1, a basal diet plus HMBi (0 g prepartum and 18 g postpartum); and iii) T2, a basal diet plus HMBi (10 g prepartum and 18 g postpartum). Treatments were initiated 21 d before expected calving and continued through 91 d postpartum. HMBi was top-dressed onto the total mixed ration of each cow. Treatments did not affect dry matter intake, plasma urea nitrogen, peak milk yield, days to peak milk yield, nonesterified fatty acid, glutamate pyruvate transaminase, glutamic oxalaetic transaminase, milk fat content, milk protein content, milk lactose content, and milk solid non-fat content. The milk composition yields were increased by the HMBi-supplemented treatment. The T1 and T2 treatments increased the yields of 4% fat-corrected milk yield, milk fat, milk protein, and milk lactose compared with the control. Although there was no difference in the milk composition of the control and T2-treated cows, the T2-treated cows exhibited higher milk fat yield (increased by 74 g/d), lower milk urea nitrogen (reduced by 3.41%), and plasma ${\beta}$-hydroxy butyrate than the control cows. The results indicate that HMBi supplementation to diet has beneficial effects, and that there is no difference between supplementation at prepartum and starting only at parturition.

We have developed a reliable and high-frequency genetic transformation and regeneration system via somatic embryogensis of Eleutherococcus sessiliflorus. Embryogenic callus obtained from seed were co- cultivated with Agrobacterium tumefaciens strain EHA101/pIG121Hm harboring genes for intron-$\beta$-glucoronidase(GUS), kanamycin and hygromycin resistance. Following co-cultivation, two types of samples(fine embrogenic calli and early globular embryo clusters) were cultivated on Murashige and Skoog(MS) medium containing 1 mg/L2.4-D for 3day in dark. Transient expression of GUS gene was found to be higher in the early globular embryo clusters than in the embryogenic calli. Also, co-cultivated period affected expression of GUS gene; the best result was obtained when globular embryo clusters were co-cultivated with Agrobacterium for 3 days. Subsequently, this callus transferred to selective MS medium containing 1mg/L2.4-D, 50mg/L kanamycin or/and 30mg/L hygromycin and 300mg/L cefortaxime. These embryogenic calls were subcultured to the same selection medium at every 2 weeks intervals. Approximately 24.5% of the early globular embryos co-cultivated with Agrobacterium for 3days produced kanamycin or/and hygromycin-resistant calli. Transgenic somatic embryos were converted into plantlets in half strength MS medium supplemented with 3mg/L GA$_3$ kanamycin and were confirmed by GUS histochemical assay and polymerase chain reaction analysis. Genomic Southem blot hybridization confirmed the incorporation of NPT II gene into the host genome.

This study was conducted to examine the effects of hormone and sodium pyruvate on in vitro maturation of canine oocytes. Canine oocytes were collected from the ovaries of dogs and cultured in NCSU-37 medium with hormones and sodium pyruvate for 72 hr. Oocytes matured to the metaphase II (MII) stage were observed only from estradiol $17{\beta}\;(E_2)$, and the presence of gonadotropin did not improve the nuclear maturation. No oocytes were developed to the MII stage when $E_2$ was added to medium during the first 6 and 24 hrs of culture period. The presence of $E_2$ during the whole culture period enhanced the nuclear maturation to the MII stage (6.0%, P<0.05). High concentration of sodium pyruvate (2.5 mM) slightly enhanced the nuclear maturation to the metapahse I (HMI) stage, but not the MII stage. the result of the present study shows that the presence of $ E_2$ during the whole culture period of 72 hr enhances the maturation of canine oocytes to the M stage, but sodium pyruvate does not affect the nuclear maturation of the canine oocytes.

Purpose : The Purpose of this research was to investigate the effects of Haingkyunghonghwatang (HKHHT) on anti-inflammatory effects. Methods : As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators were determined in mouse lung fibroblast cells(mLFC) and RAW264.7 cells. Also, changes in pathological features by drug treatment were investigated in the in vivo edema-induced rats by carrageenin/arachidonic acid or in the colitis-induced mice by DSS treatment. Results : The cytotoxicity of HKHHT on mLFC and RAW264.7 cells wasn't observed at 100, 50, 10, and $1{\mu}g/ml$ of The treatments. $IL-1{\beta}$, IL-6 and NOS-II mRNA expression of RAW264.7 cells was inhibited by The treatments in a dose-dependent manner. HKHHT treatment of RAW264.7cells(HtRc) inhibited $TNF-{\alpha}$ and COX-2 mRNA expression. HtRc significantly inhibited IL-6 and NO production. HtRc inhibited ROS production. HKHHT inhibited rat's paw edema induced by carrageenin or arachidonate treatment in all concentrations examined. The body weight and colon length of colitis-induced mice were recovered to a normal level by DSS treatment. Clinical disease levels were significantly improved compared to the control animals. HKHHT treatment of colitis-induced mice(HtCm) significantly increased hematological values such as WBC and RBC counts, Hgb and HCT levels, but decreased PLT values. HtCm decreased IL-6 and $TNF-{\alpha}$ production significantly HtCm significantly increased CD3+(T) cell counts. In contrast, HKHHT treatment decreased CD19+ B cell counts and CD3+/CD69+ significantly, and also decreased B/T ratio (%) though not significant. Conclusion : These results indicated that HKHHT could be used for treating diverse female diseases caused by the inflammation.

Purpose: In the previous in vitro studies the bone marrow stromal cells(BSCs) have shown the superior effect for wound healing activity than fibroblasts, which includes cell proliferation, type I collagen synthesis, and the production of bFGF, VEGF and TGF-${\beta}$ in chronic wound healing. The aim of this study is to compare the effects of BSCs and fibroblasts on wound healing activity in vivo, especially on collagen synthesis. Methods: The fibroblasts and BSCs were harvested from patients and cultured. The cultured cells were infiltrated into the pores of polyethylene discs. These discs were divided into three groups according to the mixed cells. In groups I, II and III the discs were loaded with no cells, fibroblasts and BSCs, respectively. Twelve discs per group(total 36 discs) were made for this study. After creating 6 pockets in the back of each rats, each discs was implanted into each pockets. At three time intervals from 1 to 3 weeks, the implanted discs were harvested for the histological and quantitative analysis. The amount of collagen produced was evaluated using ELISA. Statistical comparisons were made using the Mann-Whitney U-test. Results: There was great difference in the collagen synthesis among the three groups by the 1st and 2nd weeks. The BSC group showed highest collagen level, followed by fibroblast group and no cell group(p<0.05). The 3rd week specimens also showed greater collagen amount in BSC and fibroblast groups compared to those of no cell group(p<0.05). However, there was little difference between BSC and fibroblast groups. Conclusion: This result demonstrates that BSC has superior effect on stimulating wound healing than fibroblast, which is currently used for wound healing.
