Ixeris sonchifolia Hance(Godulbaegi), Oenanthe javanica(Dolminari), Fagopyrum esculentum Moench(Buckwheat), Hizikia fusiforme(Seaweed Fusiforme) and Zingiber officinale Roscoe(Ginger) have all been used as one of the traditional remedies as well as food source. There are few studies However, on their immunomodulating effects have been reported. We previously reported that ex vivo supplementation of each of the Ish, Oj, Fem, Hf and Zor water extracts enhanced the splenocytes proliferation compared to the control group. In this study, the combined immunomodulative effects of a plant water extract mixture containing these five food sources(Ish+Oj+Fem+Hf+Zor) was compared to the individual effect of each. The production of cytokine(IL-1${\beta}$, IL-6, and TNF-${\alpha}$), secreted by macrophages stimulated with LPS or without, were detected via ELISA assay using a cytokine kit. After 48hrs of incubation with mitogen(ConA or LPS) stimulation, the mouse splenocyte proliferation in the experimental group had significantly increased at two different concentrations compared to the control group. The results of this study may suggest that the supplementing with a plant water extract mixture could regulate immune function by increasing splenocyte proliferation as well as enhance immune function by regulating the cytokine production capacity activated macrophages in mice.

Objectives : In the present study, the author intended to investigate Gagam-jeonggitang(GJT), Gami-hwajeongjeon(GHJ) and Gami-tonggyutang(GTT) significantly affect in vivo and in vitro mucin secretion from airway epithelial cells. Methods : In vivo experiment, the author induced hypersecretion of airway mucin, hyperplasia of tracheal goblet cells and the increase in intraepithelial mucosubstances by exposing rats to SO2 during 3 weeks. Effects of orally-administered GJT, GHJ and GTT during 1 week on in vivo mucin secretion and hyperplasia of tracheal goblet cells were assesed using ELISA and staining goblet cells with alcian blue. For in vitro experiment, confluent HTSE cells were metabolically radiolabeled with 3H-glucosamine for 24 hrs and chased for 30 min in the presence of each agent to assess the effects of each agent on 3H-mucin secretion. Possible cytotoxicities of each agent were assessed by measuring lactate dehydrogenase release. Also, the effects of each agent on contractility of isolated tracheal smooth muscle and effects of each agent on MUC5AC gene expression in cultured HTSE cells were investigated. Results : GJT, GHJ and GTI inhibited hypersecretion of in vivo mucin: GJT and GHJ inhibited the increase of number of goblet cells. However, GTT did not affect the increase of number of goblet cells; GJT and GTT significantly increased mucin secretion from cultured HTSE cells, without significant cytotoxicity. GHJ increased mucin secretion and showed mild cytotoxicity at the highest concentration: GJT, GHJ and GTT chiefly affected the 'mucin' secretion; GJT, GHJ and GTT did not affect Ach-induced contraction of isolated tracheal smooth muscle; GTT did not significantly affect the expression levels of MUC5AC gene. However, GJT significantly. inhibit the expression levels of MUC5AC gene and GHJ significantly increased the expression levels of MUC5AC gene. These results suggest that GJT, GHJ and GTI can increase mucin secretion during short-term treatment(in vitro), whereas it can inihibit hypersecretion of mucin during long-term treatment(in vivo) and GJT and GHJ can not only affect the secretion of mucin but also affect the expression of mucin gene. Conclusions : The author suggests that the effects GJT, GHJ and GTT with their components should be further investigated and it is valuable to find, from oriental medical prescriptions, novel agents which might regulate hypersecretion of mucin from airway epithelial cells.

Background: Spinal nerve ligation (SNL) injury in rats produces a pain syndrome that includes mechanical and thermal allodynia. Previous studies have indicated that proinflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) play an important role in peripheral mediation of neuropathic pain, and that altered dorsal root ganglion (DRG) function and degree of DRG neuronal apoptosis are associated with spinal nerve injury. The present study was conducted to evaluate the expression of TNF-${\alpha}$ and the extent of apoptosis in the dorsal root ganglion after SNL in rats. Methods: Sprague-Dawley rats were subjected to SNL of the left L5 and L6 spinal nerves distal to the DRG and proximal to the formation of the sciatic nerve. At postoperative day 8, TNF-${\alpha}$ protein levels in the L5.6 DRG were compared between SNL and naive groups using ELISA. In addition, we compared the percentage of neurons injured in the DRG using immunostaining for apoptosis and localization of activated caspase-3. Results: SNL injury produced significant mechanical and cold allodynia throughout the 7-day experimental period. TNF-${\alpha}$ protein levels were increased in the DRG in rats that had undergone SNL ($12.7{\pm}3.2$ pg/100 ${\mu}g$, P < 0.001) when compared with naive rats ($4.1{\pm}1.4$ pg/100 ${\mu}g$). The percentage of neurons or satellite cells co-localized with activated caspase-3 were also significantly higher in rats with SNL than in naive rats (P < 0.001, P < 0.05, respectively). Conclusions: SNL injury produces mechanical and cold allodynia, as well as TNF-${\alpha}$ elevation and apoptosis in the DRG.

This in vitro study monitored MMP-8 production on PMN by stimulated with the following three groups; Sonicated extracts of E. faecalis (SEF), SEF treated with $Ca(OH)_2$ (12.5mg/ml) for 7 days, and lipopolysac-charides(LPS) of E. coli. The level of MMP-8 in each group was immediately measured by ELISA. The data were analyzed with Kruskal-Wallis test and Mann-Whitney U test. In the SEF group, the level of production of MMP-8 was higher than the negative control group in low concentration ($0.05{\mu}g/ml$) of SEF (p < 0.05). but it decreased with an increase in the concentration of SEF (p < 0.05). In the case of SEF treated with $Ca(OH)_2$, all of the MMP levels were higher than negative control group (p < 0.05), but no statistical difference was found among the different SEF concentrations (p > 0.05). All of the levels in E. coli LPS were incresed with increasing concentrations (p < 0.05). According to this study we could summarized as follows: 1. MMP-8 was expressed at low level in untreated PMN group the levels of MMP-8 were upregulated in PMN stimulated by E. coli LPS groups. 2. In the SEF groups, the level of production of MMP-8 decreased with an increase in concentration of SEF (p < 0.05). So E. faecalis may have suppressive effect on the production of MMP-8 by PMN. 3. In the case of SEF treated with $Ca(OH)_2$, all of the MMP levels at different SEF concentrations were higher than untreated PMN group (p < 0.05), but no statistical difference was found among the different SEF concentrations (p > 0.05).

Recently, the major viral diseases, Newcastle disease (ND), infectious bronchitis (IB), low pathogenic avian influenza (LPAI), avian pneumovirus infection (APV), Marek's disease (MD) and infectious bursal disease (IBD), have led to huge economic losses in chicken industry of Korea. To evaluate prevalence of the major viral disease infections in broiler breeder and broiler farms, epidemiological survey has been conducted in Jeonbuk province from 2005 to 2007 by serological ELISA test for APV, PCR for MD, and RT-PCR for ND, IB, LPAI and IBD, respectively. A total of 424 cases was submitted to our laboratory for diagnosis of the major viral disease from broiler breeder and broiler farms in the above period. The diagnosed results were analysed for the detection rate of infections on basis of years, seasons and ages, respectively. This study was showed that the detection rates of ND and APV were considerably high for every years regardless of seasons and ages in both broiler breeder and commercial broiler. In comparison with detection rates of ND and APV, IB and LPAI were lower but detected around 10% for every years. Especially, detection rate of IB was significantly high in commercial broiler than in broiler breeder. Therefore, to minimize economic losses for broiler breeder and broiler farms, it will need for effective countermeasures to decrease detection rate of the viral respiratory diseases. Although the detection rates of MD and IBD were gradually decreased from 2005 to 2007 in both broiler breeder and commercial broiler, it will continually make an effort about disease control for increasing productivity in chicken industry.

Objective : Soybeans of Canavalia gladiata(CG) and root of Arctium lappa(AL) have been reported to have anti-inflammatory, antioxidant effect. However, the immunoregulatory mechanisms of its combinational prescription remain a matter of considerable debate. In the current study, we investigated whether CG and AL and its combinational prescription(CG+AL) regulate immune system using chronic immobilization-stress mouse model. Methods : C57BL/6J mice fixed for 2 hours into immobilization tube after CG, AL, CG+AL oral administration after 2 hours daily for 21 days. After every experiment has ended the C57BL/6J mice were sacrificed on 22 days. The production of Serotonin and Cortisol, lgA were observed by ELISA method, The proportion of immune cells such as T/B cell and macrophage, NK cell were measured by FACS. Then, Real-time PCR was performed to measure the mRNA expression of Inflammatory cytokines(IL-1beta, IL-6, TNF-a) and T cell activation cytokines(IL-2, IL-10, IFN-gamma, IL-12p35 / p40). Result : When chronic immobilization-stress mouse model were treated with CG+AL(1:4), the expression of mRNA were significantly decreased at the Inflammatory cytokines(IL-1beta, IL-6, TNF-a). While, the levels of mRNA were significantly increased at immune T cell activation cytokines. Additionally, CG+AL(1:4) combinational prescription group enhanced immune cells such as T/B cell and macrophage, NK cell. Furthermore, the Immuno-fluorescence result of brain tissue can confirm that CG+AL(1:4) group significantly increased the BDNF expression. Conclusion : These result suggest that CG+AL(1:4) combinational prescription has Immune System enhancement via stress-mediated immunocyte.

Objectives: This study was performed to investigate the effects of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) on the monosodium iodoacetate(MIA) induced early state osteoarthritis in rats. Methods: Osteoarthritis was induced by injection of MIA(0.25 mg) into knee joints of rats. Osteoarthritis rats were divided into control(n=8) and treated=8 group respectively, Control group was taken distilled water and treated group was taken extracts of Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) by orally for 20 days. Body weight was measured at 0, 5, 10, 15, 20 days after MIA injection. At the end of experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan(PG) content of articular cartilages were analysed by safranine O staining method. The content of tumor necrosis $factor-{\alpha}(TNF-{\alpha})$, $interleukin-1{\beta}(IL-1{\beta})$ in synovial fluids were analysed by enzyme-inked inmunosorbent assay(ELISA) method. And also cycloxygenase-2(COX-2), matrix metalloproteinase 3(MMP-3), inducible nitric oxide synthase(iNOS), calpain immunochistochemical examination on the knee joints were performed. Results: PG content in articular cartilages of the treated group was significantly increased compared with control group. Histopathological osteoarthritic score of the treated group was significantly decreased compared with control group. $TNF-{\alpha}$ content in synovial fluids, expression of iNOS and calpain in synovial membrane of the treated group were significantly decreased compared with control group. But body weight, $1L-1{\beta}$ content in synovial fluids, expression of iNOS and MMP-3 of the treated group were not significantly changed compared with control group. Conclusions: On the basis of these results, we conclude that Gagamsosokmyeong-tang(Jiajianxiaoxuming-tang) has anti-arthritic effects on the MIA induced early stage osteoarthritis in rats.

Chunghyul-dan (CHD) is a combinatorial drug known to exert anti-inflammatory effects in endothelial cells. In this study, we employed global transcriptional profiling using cDNA microarrays to identify molecular mechanisms responsible for the anti-inflammatory activity of CHD in endothelial cells. An analysis of the microarray data revealed that transcript levels of monocyte chemotactic protein-1 (MCP-1), vascular cell-adhesion molecule-1 (VCAM-1) and activated leukocyte cell-adhesion molecule were dramatically altered in CHD-treated endothelial cells. These changes in gene expression were confirmed by RT-PCR, Western blotting and ELISA. Chronic CHD treatment also appeared to decrease MCP-1 secretion, probably as a result of decreased MCP-1 expression. In addition, we determined that chronic CHD treatment inhibited lipopolysaccharide-stimulated adhesion of THP-1 leukocytes to endothelial cells. The inhibitory effect of CHD on LPS-stimulated adhesion resulted from downregulation of VCAM-1 expression. Transmigration of THP-1 leukocytes through endothelial cells was also inhibited by chronic CHD treatment. In conclusion, CHD controls a variety of inflammatory activities by regulating MCP-1 and VCAM-1 gene expression.
