Antigenicity of recombinant human interferon $\beta$(LB00013), a newly developed drug for anti-cancer and anti-viral therapeutic use, was investigated in mice and guinea pigs. The following results were obtained: 1. Mice showed no production of antibodies against LB00013 sensitized with aluminum hydroxide gel (Alum) as an adjuvant, when judged by the heterologous passive cutaneous anaphylaxis (PCA) test in rats. Meanwhile, antibodies against ovalbumin (OVA) sensitized with Alum were clearly detected. 2. In guinea pigs, the sensitization of neither LB00013 only nor LB00013 with complete Freund's adjuvant (CFA) produced positive reactions in the homologous active systemic anaphylaxis (ASA) and the PCA tests. Meanwhile, the sensitization of OVA with CFA produced positive reactions in both PCA and ASA. 3. A LB00013-specific reaction was not observed in an indirect hemagglutination(IHA) assay using sera isolated from LB00013 sensitized mice. The present results suggested that LB00013 may have no antigenic potential in mice and guinea pigs.

Objective : Propolis (PP) has been used in oriental medicine. PP has various biological activities. However, its immunoregulatory and anti-inflammatory activities have not been well studied. In this study, I investigated these activities of PP by using ovalbumin-induced allergic asthma in mice. Methods : To examine the effect of PP on allergic asthma, mice were sensitized with $100{\mu}g$ of OVA and 1mg of aluminum potasssium sulfate (Alum; Sigma) intraperitoneally on day 0 and 7. On day 14, mice were challenged on consecutive 3 days with 5% OVA and AHR was assessed 24 hours after the last challenge. To examine severity of AHR, I examined the population of eosinophiles and T cells in spleen and lung and cytokine production in T cells. Futhermore, I examined histological changes during the OVA-induced allergic asthma. Results and Conclusion : PP reduced the population of eosinophil and CD4+ T cells on the OVA-induced AHR mice model. PP also inhibited IL-4 production but increased INF-g production in T cells. These results suggest that PP may be beneficial material for allergic asthma.

Objective : Kumsoouyukkun-joen extract(KSE) has been used treating asthma for a long time in korea. In the present study, I examined the effects of KSE on the ovalbumin(OVA)-induced airway hyper-reactivity(AHR). Methods : To examine the effects of KSE on asthma, mice were sensitized with $100{\mu}g$ of OVA and 1 mg of aluminum potassium sulfate(Alum; Sigma)intraperitoneally on day 0 and 7. On day 14, mice were challenged on 3 consecutive days with 5% OVA and AHR was assessed 24 hrs after the last challenge. To examine severity of AHR, I examined eosinophil population and cytokine production in bronchoaveloar lavage fluid(BALF) and stained with hematoxylin and eosin in lung and also measured enhanced pause(Penh) in AHR from mice. Results and Conclusion : KSE potently inhibited the development of Penh and also reduced the number of eosinophil during OVA-induced AHR. KSE also inhibited cytokines production such as IL-4, IL-5 in BALF. Furthermore, KSE inhibited percentage of eosinophil in BALF. These results suggest that KSE may be beneficial oriental medicine for AHR.

1. Objectives: Three herbal formulas (Yuldahanso-tang, Chungsimyonja-tang, and Taeeumjowi-tang) for Taeeumin were applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in murine macrophage cell line (RAW 264.7) and ovalbumin (OVA)-immunized mice. 2. Methods: This study was carried out in nitric oxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes according to three herbal formulas. C57BL/6 mice were immunized intraperitonially with OVA/aluminium ($100\;{\mu}g/200\;{\mu}g$/mouse) on day 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. 3. Results: Yuldahanso-tang and Chungsimyonja-tang increased NO synthesis in RAW 264.7 cells. Three herbal formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<.001). Three herbal formulas for Taeeumin also significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. 4. Conclusion: These results suggested that three herbal formulas for Taeeumin could be used as stimulator of immune response.

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.

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.

Activated T helper 2 (Th2) immune function is hallmark of various allergic diseases. We investigated the anti-allergic effect of Jagamcho-tang extract(JE) on ovalbumin(OVA)-induced atopic dermatitis mice model and OVA-stimulated splenocytes isolated from the mice. Mice were intraperitoneally injected OVA/alum solution 2 times at interval of 14 days, followed by oral administration of JE for 7 days. After administration, mice were subcutaneously injected with OVA in ear. JE treatment reduced ear swelling and infiltration of inflammatory cells in ear. Serum levels of interleukin(IL)-4 and immunoglobulins, such as total-IgE and OVA-specific IgE, were decreased in JE treated group. Furthermore, JE treatment decreased OVA-induced Th2-associated cytokines like IL-4, IL-5 and IL-13 mRNA levels in splenocytes. In conclusion, JE reduced allergic immune response via IgE production and Th2 response in OVA-sensitized mice, suggesting that JE could be useful prescription for allergic diseases including atopic dermatitis.

Objectives : Gagam-Gongjin-dan (GGD) composited with Cervi parvum Cornu, Corni Fructus, Angelica gigantis Radix, Lycii Fructus, Dioscoreae Rhizoma, Citri Pericarpium, Gastrodiae Rihzoma, Agastachis Herba, Cassiae cortkex, Scutellariae Radix, Schisandrae Fructus has been traditionally used for chronic diseases or weakness after illness in oriental countries. However, little is known about the effects of methanol extract of GGD on immune responses to ovalbumin (OVA) plus alum. Therefore, the purpose of this study was to investigate the effects of GGD on immune responses to ovalbumin plus alum in Balb/c mice. Methods : In this study, the extract of GGD was prepared by extracting with methanol for 7 days. The extract was freeze-dried following filtration through vacuum distillation system. Mice were orally administrated with or without GGD extract of different doses (50-200 mg/kg/day) for 30 days. We examined the effects of GGD extract on the serum levels of total IgE, OVA-specific IgE, IgG1, IgG2a, and CTACK/CCL27 production and CCR10 expression in lymph node cells and body weight change and foot pad swelling responses in ovalbumin treated Balb/c. Results : The oral administration of GGD dose-dependently reduced the serum levels of total IgE, OVA-specific immunoglobulin (IgE, IgG1 and IgG2b) and CTACK/CCL27 production in ovalbumin treated BALB/c mice. The levels of CCR10 expression from lymph node cells of OVA treated mice were markedly suppressed by treatment with GGD in a concentration dependent manner. Furthermore, foot pad swelling responses were also markedly suppressed by GGD. However, body weight were significantly increased dose dependently by GGD treatment. Conclusions : These results suggest that GGD treatment suppresses immune responses to ovalbumin, and these properties may contribute to allergic disease care.

Objectives : To investigate the immunological activities, we evaluated the combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix (AG) on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. Methods : The cellular proliferation and the production of nitric oxide were examined in a macrophage cell line, RAW 264.7 cells, in the presence of the combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix. C57BL/6 mice were immunized intraperitonially with ovalbumin/aluminium ($100{\mu}g/200{\mu}g$) on day 1, 8, and 15. The combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix (1 g/kg/day) was orally administrated for 3 weeks. On day 22, splenocyte and plasma were collected for mitogen-induced proliferation, lymphocyte subpopulation by flow cytometry and measurement of AST (Aspirate aminotransferase), ALT (Alanine aminotransferase), and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes). Results : Aconiti Lateralis Radix Preparata treatment had no influence on immune responses. The proliferation and NO production of macrophage and proliferation of splenocyte were increased as the higher ratio of Glycrrhizae Radix. The proliferation of splenocyte, lymphocyte subpopulation and production of antibody (total IgM, OVA-specific IgG and OVA-specific IgG1) were increased as the higher ratio of Glycrrhizae Radix on OVA-immunzed mice. Conclusions : These results suggest that the higher ratio of Glycyrrhizae Radix can increase immunological activities such as NO production in RAW264.7 cells, splenocyte proliferation and immunoglobulin production in OVA-immunized mice.

Antigenicity of Recombinant Granulocyte macrophage colony stimulating factor(LBD-005), a newly developed drug for hematopoietic growth, was investigated in mice and guinea pigs. 1. Mice showed production of antibodies against LBD-005 (100mg/kg) with alumin]m hydroxide gel(alum) as an adjuvant, judged by the heterologous anaphylaxis(PCA) test using rats. On the other hand, antibodies against ovalbumin(OVA) inoculated with alum were definitely detected. 2. In the studies with guinea pigs, both the inoculation of LBD-005 only and of LBD-005 with complete Freund's adjuvant(CFA) as an adjuvant did not produce positive reactions in homologous passive cutaneous anaphylaxis (PCA).
