This study is aimed to investigate the anti-inflammatory effect of Euphorbiae kansui radix methanol extract (ERE) in lipopolysaccharide(LPS)-stimulated mouse peritoneal macrophages. Peritoneal macrophages were obtained from thioglycollate-injected Balb/c mice. Cells were stimulated with LPS or LPS plus interferon-gamma (IFN-${\gamma}$) in the presence of ERE and various inflammatory markers were assayed. Finally, LPS-induced signaling molecules were measured. ERE up to $400{\mu}g/m{\ell}$, was not cytotoxic to ERE inhibited LPS/IFN-${\gamma}$-induced nitric oxide (NO), inducible NO synthase. ERE also reduced the levels of cyclooxygenase-2 and the proinflammatory cytokines such as tumor necrosis factor-${\alpha}$, interleukin(IL)-6 and IL-12. The inhibitory effect of ERE on LPS-induced $I{\kappa}B{\alpha}$ degradation was weak but phosphorylation of JNK, p38 and ERK1/2 was strongly suppressed. Our data indicated that the anti-inflammatory effect of ERE in LPS-stimulated macrophages was partly mediated by its inhibition of JNK, p38 and ERK1/2.

Specific polyclonal and/or monoclonal antibodies (MAbs) to immunoglobulins (Igs) and their subunits have proved to be valuable tools in immunological research and in immunological assays. In this study, we developed and characterized MAbs against flounder serum Igs. To obtain the pure flounder serum Igs, mouse IgG (mIgG) was immunized to flounder. Flounder Igs were purified by using mIgG-agarose affinity column chromatography. The structure of purified flounder Ig was observed, on denatured SDS-PAGE, to be composed of two heavy chains (77 and 72 kd) and two light chains (28 and 26 kd). MAbs were produced by fusion of myeloma cells (SP2/0) with Balb/c mouse spleen cells previously primed with the flounder Igs. Finally, three hybridoma clones, FIM 511, FIM 519 and FIM 562 were established to recognize both 2 heavy chains, 26 kd of light chain and 28 kd of light chain, respectively. On the other hand, the flounder immune sera collected on the weekly basis were tested on ELISA and immunoblot analysis whether boosting effect is present in flounder humoral immune system. As a result, the secondary immune response in flounder was ascertained on ELISA, but not on immunoblot analysis. Further, we observed an alteration of serum protein levels following immunization. Our MAbs and basic information on flounder humoral immune system obtained in this study will be helpful to control and monitor the efficiency of fish vaccines and therapeutic process of flounder diseases.

Objective : For various reasons, Obesity & Rhinitis are constantly rising. So Interest of treatment has been expanding. We want to verify The Chungyeol (fire extinguishing) Lisup (Draining) effect of Bangpungtongsungsan on obese model of allergy rhinitis.Material and Methods : BALB/c mouse were divided four groups: control(CON), allergic induction(ARE), Bangpungtongsungsan extract administration(BTT), Bangpungtongsungsan double concentration extract administration (BT2T). Every group except control group were caused allergic rhinitis by Ovalbumin. BTT & BT2T were orally administered the Bangpungtongsungsan for 21days. Since then we observed the liver tissue cell and the nasal mucous membrane.Results : In comparison with ARE, experimental groups show relief of the nasal mucous membrane damage(secretion of mucus decrease, Itching decrease), Th2 eruption control(IL-4 decline), effect of anti-inflamatory(reducing TNF-α creation, decreasing of iNOS through NF-κB activation-inhibition). In addition, experimental groups show a loss in weight, diminished accumulation of fat. (decreasing within liver tissue, reducing TNF-α creation) BT2T is more effective to BTT.Conclusion : Bangpungtongsungsan treat obese model on allergy rhinitis thereby control fat augmentation, relieving inflammation.

Galectin-3 plays an important role in cell development, differentiation and cancer metastasis, including cell-cell/extracellular matrix (ECM) interactions and is supposed to have an effect of apoptosis on T-cells in thymic clonal selection. In this study, to know the effect of galectin-3 on thymocyte development, we used recombinant human galectin-3 (rHgal-3) from Escherichia coli, JM105, which was inserted with human gal-3 gene-transformed plasmid vector (prGal-3) to express human galectin-3. Expressed rHgal-3 was confirmed by western blot using the culture supernant of hybridoma (M3/38) producing monoclonal antibody to human galectin-3. Sepharose gel affinity chromatography was used to purify the expressed rHgal-3. Thymocytes and hepatocytes from 6-week-old male BALB/c mice were incubated with rHgal-3 and showed marked increase of apoptotic population on analysis using flow cytometry with 7-AAD in a dosedependent manner. However, rHgal-3 failed to induce apoptosis on hepatocytes. Interestingly, this apoptotic effect was not inhibited by lactose, a specific lectin domain inhibitor. From these results, we concluded that extrinsic -3 induces apoptosis on mouse thymocytes, and galectin-3 may have an apoptotic effect on T-cells in thymic clonal selection.

The present study examined the ex vivo effect of Job's tear on immune function. Seven to eight week old mice(Balb/c) were fed a chow diet ad libitum two different concentrations (50 and 500 mg/kg BW) of water extract of Job's tear were orally administ every other day for two weeks. The results indicated that macrophage activation had occurred in the mice receiving 50 mg/kg B. W. of Job's tear water extract. Overall, using a mouse model, this study demonstrated that Job's tear extract may enhance immune function by regulating the $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ and IL-10 cytokine production capacity of activated macrophages in mice. This study may suggest that supplementation of Job's tear water extracts may enhance the immune function by regulating the enhancing the cytokine production by activated macrophage ex vivo.

In order to investigate the cytotoxicity of composite resin in vitro, BALB / C mouse fibroblast were cultured in MEM in which silux, P-50, microrest, clearfil, amalgam and glass - ionomer, in shape of $2{\times}9mm$ circular disk. The experiments were- performed by cell count on 4 hours, 1, 3, 6 days and the composite resin groups, amalgam, glass - ionomer were compared. 1. On the sixth day, the cellular number of resin composite groups were remarkedly reduced, in contrast, the that of amalgam and glass - ionomer group continuously increased. 2. It was only on the 4 hours that the cellular number contained in amalgam were reduced, but increased thereafter, and the cellular number contained in glass - ionomer are greater than other groups. 3. In resin group, especially between self - curing resin and light - curing resin, there is no difference in cellular number statistically (p>0.05). 4. It was amalgam where the round cell without cellular process was found on the 4. hours and on the 6 th day the cell without cellular process was found numeroulsy in resin group whereas in amalgam and glass - ionomer, like control group was contained cell forming monolayer. These result suggested that the toxicity of the self - curing and light - curing resin greater than that of the amalgam and glass - ionomer.

Antitumor effects of hexane, chloroform fractions and tannins from persimmon leaves were studied by using sarcoma-180 tumor cells. The solid tumor growth was inhibited most effectively when 0.5mg/kg of hexane fraction was administerated to the Balb/c mouse. The life prolongation effects were 35.6%, 11.5% and 29.9%, respectively when hexane fraction, chloroform fraction and tannins from the persimmon leaves were administerated to the mouse. Spleen index, a marker for immunological activity, was increased in mice administrated hexane fraction, chloroform fraction and tannins of persimmon loaves, compared with the control group.

The diagnosis of Brucella abortus is mainly based on serological methods using antibody against LPS, which has diagnostic problems. Therefore, to solve this problem, we evaluated two proteins of B. abortus, Cu/Zn superoxide dismutase (SodC) and outer membrane proteins 2b porin (Omp2b). The genes were cloned and expressed in a pMAL system, and the recombinant proteins, rOmp2b and rSodC, were purified as fusion forms with maltose-binding protein. The identity of the proteins was confirmed by SDS-PAGE and Western blot analysis with sera of mice infected with B. abortus. Production of cytokines and nitric oxide (NO) was investigated in RAW 264.7 cells and mouse splenocytes after stimulation with the proteins. Moreover, cellular and humoral immune responses were investigated in BALB/c mice after immunization with the proteins. TNF-${\alpha}$, IL-6, and NO were significantly inducible in RAW 264.7 cells. Splenocytes of naive mice produced IFN-${\gamma}$ and IL-4 significantly by stimulation. Moreover, number of IgG, IFN-${\gamma}$, and IL-4 producing cells were increased in immunized mice with the two proteins. Production of IgG and IgM with rOmp2b was higher than those with rSodC in immunized mice. These results suggest that the two recombinant proteins of B. abortus may be potential LPS-free proteins for diagnosis.

These experiments were carried out to clarify the optimalconditions and interspecific cross reaction of H-Y antibody activity. H-Y antiserum was prepared in inbred SD female rats and Balb/c female mice by repeated immunization of rat newborn testis homogemate, rat and mouse spleen cells obtained from males of same strain. The activity of H-Y antibody in antiserum was tested by ELISA and biological tests. The cross reactivity of H-Y antibody was confirmed by culturing mouse and rabbit embryos in medium containing H-Y antibody and complement obtained from rat and guinea pig, respectively. The optimal condition for the activity of H-Y antibody was also investigated by culturing embryos in medium with different pH and complement concentration. The results obtained in these experiments were summarized as follows: 1. The formation rates of H-Y antibody in rats immunized with newborn testis and spleen cell were 40.0 and 50.0% respectively, and that in mouse immunized with spleen cell was 48.4%. 2. The activity of H-Y antibody was not affected by pH in range of 6.5 to 8.0, and the same was true for the relative concentration of complement to the H-Y antibody. 3. Minimum time needed for the activity of H-Y antibody was confirmed to be 0.5 to 1 hour and 24 to 48 hours respectively for the zona free embryos and intact embryos. 4. When mouse and rabbit embryos were treated with H-Y antibody obtained from rat, 46.4 and 54.8% of embryos were retarded or destroyed. From these results it could be said that H-Y antibody had strong interspecific cross reactivity.
