1. Objectives Yanggyuksanhwa-tang for Soyangin was applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. 2. Methods This study were carried out in nitric oxide (NO) synthesis on RAW 264.7 cells and cellular proliferation on mouse splenocytes. C57BL/6 mice were immunized intraperitonially with OVA/Alum (100 ${\mu}g$/200 ${\mu}g$) on day 1, 8, and 15. Yanggyuksanhwa-tang was administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. 3. Results Yanggyuksanhwa-tang significantly enhanced cellular proliferation by LPS and Con A on splenocytes from OVA/Alum-immunized mice (p<.001). Yanggyuksanhwa-tang also significantly enhanced plasma OVA-specific IgG (p<.001), IgG1 (p<.001), and total IgM (p<.01) levels compared with the OVA/Alum group. 4. Conclusions These results suggested that Yanggyuksanhwa-tang for Soyangin could be used as immunopotent.

Dexamethasone (Dex) was shown to inhibit the differentiation, maturation, and antigen-presenting function of dendritic cells (DC) when added during DC generation or maturation stages. Here, we examined the direct effects of Dex on MHC-restricted antigen processing. Macrophages were incubated with microencapsulated ovalbumin (OVA) in the presence of different concentrations of Dex for 2 h, and the efficacy of OVA peptide presentation was evaluated using OVA-specific CD8 and CD4 T cells. Dex inhibited both class I- and class II-restricted presentation of OVA to T cells; this inhibitory effect on antigen presentation was much more potent in immature macrophages than in mature macrophages. The presentation of the exogenously added OVA peptide SIINFEKL was not blocked by Dex. In addition, short-term treatment of macrophages with Dex had no discernible effects on the phagocytic activity, total expression levels of MHC molecules or co-stimulatory molecules. These results demonstrate that Dex inhibits intracellular processing events of phagocytosed antigens in macrophages.

Ability of pectic polysaccharides isolated from Eleutherococcus senticosus EN-3 to inhibit tumor metastasis and induce antigen-specific immune response after oral administration in mice was assessed. Consecutive oral administration of EN-3 before tumor inoculation dramatically inhibited tumor metastasis produced by colon26-M3.1 and B16-BL6 cells. When Peyer's patch cells isolated from mouse intestine were co-cultured with EN-3, proliferation of Peyer's patch cells was induced. Mice co-administered with EN-3 and ovalbumin (OVA) showed significantly higher production of OVA-specific IgA in intestinal washing as well as IgG in serum than those administered with OVA alone. Payer's patch cells of mice immunized with OVA plus EN-3 showed much higher proliferating activity than those of mice immunized with OVA alone. Proliferating activity increased dose-dependently, indicating EN-3 specifically enhanced mucosal immune response to OVA. These results suggested EN-3 could significantly stimulate Peyer's patch cells either non-specifically or antigen-specifically, possibly playing important role in enhancement of mucosal and systemic immune systems.

Frankincense, the gum resin derived from Boswellia species, is complex mixtures composed of about $5{\sim}9%$ highly aromatic essential oil, $65{\sim}85%$ alcohol-soluble resins, and the remaining water-soluble gums. The anti-inflammatory properties of frankincense, alcohole-soluble resins, are well-recognized, but the question of whether aromatic essential oil also plays a role in the allergic asthma remains unanswered. This study was performed to evaluate anti-inflammatory effects of Boswellia sacra essential oil (BSEO) on ovalbumin (OVA)-induced asthma mouse model. BALB/c mice after intraperitoneal OVA sensitization were challenged with intratracheal OVA. One experimental group was inhaled with 0.3% BSEO for the later 8 weeks. BALB/c mice were sensitized and challenged with OVA and developed airway eosinophilia, mucus hypersecretion, and airway hyperresponsiveness. In contrast, the BSEO treated mice had reduced a number of eosinophils among BALF cells, goblet cell hyperplasia, and airway hyperresponsiveness. Cytokine analysis of BALF revealed that BSEO caused an increase in Th1 cytokine (interferon-$\gamma$ (IFN-$\gamma$)) and a decrease in Th2 cytokines (interleukin-4 (IL-4), IL-5 and IL-13) levels. In addition, the OVA-specific serum IgE and eotaxin levels were also reduced. In mice inhaled BSEO, $CD4^+$, $CD3^+/CCR3^+$, and $B220^+/CD23^+$ mediastinal lymph nodes cells were also decreased. These results suggest that inhaled BSEO as a immunomodulator in Th1/Th2 mediated asthma may have therapeutic potential for the treatment in allergic airway inflammation by a simple, cost-effective way.

Objectives The suppressive effect of CSBHT has been mysterious. Thus, the present study is designed to investigate the suppressive effect and its mechanism. Methods To investigate the anti-allergy effect from ChungShimBoHyeolTang(CSBHT), RBL-2H3 cell was used and examined by Real-Time PCR, and IL-4 and IL-13 from RBL-2H3 was examined by ELIS. In addition, GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos, c-Jun, NF-${\kappa}B$ p65 transcription factors of RBL-2H3 mast cell were examined by Western Blotting. Also, OVA/alum-sensitized mice were orally administrated CSBHT and serum OVA-specific IgE production, IL-4, and IL-13 production in splenocytes supernatant were examined. Results As a result of treating with CSBHT extract, RBL-2H3 mast cells significantly suppressed the IL-4 and IL-13 mRNA expression and IL-4 and IL-13 production. Western blot analysis of transcription factors involving IL-4 and IL-13 expression also revealed a prominent decreases of mast cell's specific transcription factors including GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos, and NF-${\kappa}B$ p65. Also, examining the mice, administration of CSBHT suppressed the amount of OVA-specific IgE in OVA/alum-sensitized mice and IL-4 and IL-13 production in splenocytes supernatant. Conclusions The study suggested that the anti-allergic activities of CSBHT suppresses IL-4 and IL-13 production from the Th2 cytokines by suppressing transcription factors as GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos and NF-${\kappa}B$ p65 in mast cells.

We hope to evaluate the effects of Sabaek-san for the bronchial asthma using assesment on the metrix metalloproteinase-9(MMP-9) after Sabaek-san was intravenously administered OVA-sensitized and -challenged mice. Seventy-two female mice, 8-10 weeks of age and free of murine specific pathogens, were used. Of the seventy-two mice, twenty-four mice were not sensitized and forty-eight mice were sensitized by intraperitoneal injection of OVA. Of the sensitized mice, twenty-four mice didn't administrate Sabaek-san and twenty-four administrated Sabaek-san. Mice were sensitized on days 1 and 14 by intraperitoneal injection of 20 fig OVA. On days 21, 22 and 23 after the initial sensitization, the mice were challenged for 30 minutes with an aerosol of 1% OVA in saline. Sabaek-san administered 200㎎/㎏ in the tail of the mouse, one time per day, for 7 days, beginning 14 days after first sensitization. Bronchoalveolar lavage was performed 72 hours after the last challenge, and total cell numbers in the BAL fluid were count. Also, level of MMP-9 in the BAL fluid were measured by Enzyme immunoassays and Western blot analysis. Enzyme immunoassay revealed that MMP-9 levels in the BAL fluids significantly increased 72 h after OVA inhalation compared with levels in the control group. After administration of the Sabaek-san, the levels of the MMP-9 in BAL fluids 72 h after OVA inhalation reduced dramatically. Western blot analysis revealed that MMP-9 levels increased in the all mice which were challenge with OVA without administered Sabaek-san compared the normal mouse. However, in the groups of the administered Sabaek-san, the MMP-9 level markedly decreased. Sabaek-san might be effect the treatment of the bronchial asthma as a inhibition of the MMP-9.

Objectives: We performed simultaneous determination of five constituents by HPLC in Samul-tang (SMT). Additionally, we investigated the immune-stimulatory potential of SMT on specific cellular and humoral immune responses in ovalbumin (OVA)-immunized mice. Methods: Reverse-phase chromatography using a Gemini C18 column operating at $40^{\circ}C$, and photodiode array (PDA) detection at 190-400 nm, were used for quantification of the five components of SMT. Mobile phase using a gradient flow consisted of two solvent systems. Solvent A was 1.0% (v/v) aqueous acetic acid and solvent B was acetonitrile with 1.0% (v/v) acetic acid. C57BL/6 mice were immunized intraperitoneally with OVA/alum ($100{\mu}g/200{\mu}g$) on days 1, 8, and 15. The extract of SMT (1000 mg/kg) was given to mice orally for 21 days (from day 1 to day 21). At day 22, OVA-, lipopolysaccharide (LPS)- and concanavalin A (Con A)-stimulated splenocyte proliferation and OVA-specific and total antibodies were measured in plasma. Results: Calibration curves were acquired with $r^2$>0.9999, and the relative standard deviation (RSD, %) for intra- and inter-day precision were both less than 3.5%. The recovery was in the range of 95.69-115.12%, with an RSD less than 6.0%. The contents of five components in SMT were 1.08-15.30 mg/g. SMT significantly enhanced Con A-induced splenocyte proliferation in OVA-immunized mice (p<0.01). Also, SMT significantly enhanced OVAspecific IgG, IgG1 and total IgM levels in plasma compared with the OVA-immunized group. Conclusions: The established method will be applied for the quantification of major components and immunestimulating activity in OVA-immunized mouse model of SMT.

The aim of this study was to obtain mature ova or embryos at a single cell stage, which can be used in avian transgenesis and nuclear transfer through multiple ovulations, in vitro fertilization and culture. Chicken anterior pituitary extract (CAPE) or acetone-dried chicken anterior pituitary extract (ACAPE) was used to induce multiple ovulations in hens pretreated with pregnant mare' serum gonadotrophin (PMSG). In vitro fertilization of the multiple ovulated ova was performed by inseminating sperm onto the germinal disks in m-Ringer' solution and incubating the ova at 41$^{\circ}C$, 5% $CO_2$ for 10 h in DME-F12 medium containing 20% liquid albumen. The in vitro fertilization process was observed using an environmental scanning electron microscope. When normal laying hens (white Leghorn) were administered daily with PMSG (100 IU), egg laying ceased in most hens within 3 to 8 days. Ovulation began to occur about 7.5 h after injection of CAPE and ACAPE. The number of ovulated ova was 1.00${\pm}$0.00, 2.33${\pm}$0.52 and 2.20${\pm}$0.45, respectively, after receiving 100, 200 and 300 mg CAPE. The number of ovulated ova was 2.00${\pm}$0.00, 2.86${\pm}$0.69 and 3.00${\pm}$1.22, respectively, after receiving 10, 15 and 20 mg ACAPE. The fertilized and cultured ova were able to develop into embryos up to the 32 cell stage. The present experiments demonstrated that multiple ovulations can be induced by CAPE and ACAPE successfully, and the ova resulted from the treatment retained the capability for further fertilization and embryonic development. These data provide new information to support the establishment of an in vitro culture system for future avian transgenesis studies.

Objectives: Three yin-tonifying formulae (Ssanghwa-tang, Yukmijihwang-tang and Jaeumganghwa-tang) were applied to investigate their immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in the murine macrophage cell line (RAW 264.7) and in ovalbumin (OVA)-immunized mice. Methods: This study was carried out in nitricoxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes in association with three herbal formulas. C57BL/6 mice were immunized intraperitoneally with OVA/aluminum ($100\;{\mu}g/200\;{\mu}g$/mouse) on days 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. Results: All three yin-tonifying formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<0.001). Also, these herbal formulas all significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. Conclusion: These results suggested that the three yin-tonifying formulae could be used as stimulators of immune response.
