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.

The purpose of this research was to investigate the effects of Kwakhyangjeonggisan (KJS) on the anti-allergic action. In the present study, we examined the effect of KJS on type I and type IV allergic reaction. KJS inhibited the systemic anaphylaxis induced by compound 48/80 and platelet activating factor (PAF), and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KJS dose-dependently inhibited the release of histamine from peritoneal mast cells in rat. Also, KJS inhibited the delayed type hypersensitivity (DTH) induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene (DNFB). KJS inhibited the proliferation of splenocytes, the subpopulation of B220+ cells and CD4+CD8-(Th) cells in splenocytes and the production of γ-interferon in serum and splenocytes. These findings suggest that KJS prevented the type I allergy by the inhibition of histamine release from mast cells and the type IV allergy by the inhibition of γ-interferon production and B lymphocytes subpopulation. These results indicate that KJS may be useful for the prevention and treatment of type I and type IV allergy related disease.

We studied the effect of aqueous extract of Magnolia officinalis bark (Magnoliaceae) (MOAE) on the immediate hypersensitivity reaction. MOAE (0.01 to 1g/kg) dose-dependently inhibited compound 48/80 induced systemic anaphylaxis in rats. MOAE (0.1 and 1g/kg) also significantly inhibited local immunoglobulin E (lgE)-mediated passive cutaneous anaphylactic reaction. When MOAE was pretreated at concentrations ranging from 0.01 to 1g/kg, the levels of plasma histamine were reduced in a dose-dependent manner. MOAE (0.001 to 1 mg/ml) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-dinitrophenyl (DNP) Igl. The level of cyclic AMP (CAMP) in RPMC, when MOAE was added, significantly increased compared with that of the normal control. Moreover, MOAE (0.01 to 1 mg/ml) had a significant inhibitory effect on anti-DNP Igl-induced tumor necrosis factor-$\alpha$ production from RPMC. These results indicate that MOAE inhibits immediate hypersensitivity reaction in vivo and in vitro.

The effect of aqueous extracts of medicinal plants $AMP-365^{TM}$ was tested for immune system regulating activity based on anti-inflammatory activity, anti-oxidant, macrophage proliferation and T-lymphocyte proliferation activity. $AMP-365^{TM}$ dose-dependently increased proliferation of RAW264.7 macrophage cells and its nitric oxide production as well as DPPH radical scavenging activity. On the other hand, T-lymphocyte proliferation activity was decreased on dose-dependent manner. Passive cutaneous anaphylaxis reaction was alleviated by 49% by administering 250 mg/kg of $AMP-365^{TM}$. The results suggest that $AMP-365^{TM}$ can be beneficial in the treatment of immediate allergic reactions as an adjuvant supplement material.

Antigenicity of DA-3285, human recombinant erythropoietin which was produced from mammalian cells, was examined in guinea pigs and mice. In active systemic anaphylactic test, mild anaphylactic signs were observed in guinea pigs sensitized subcutaneously with DA-3285 or DA-3285 incorporated with complete Freund's adjuvant(CFA) when challenged with high dose(1000 IU/Kg) of DA-3285. Other groups showed negative responses. In mouse-rat passive cutaneous anaphylaxis test, 20% sera of mice immunized with DA-3285 or DA-3285 mixed with aluminum hydroxide(alum) showed mild positive responses. In the case of indirect haemagglutination reaction(IHA) test, when sheep red blood cells coated with DA-3285 was incubated with mouse serum, all the serum samples were showed negative responses. These results suggest that DA-3285 has a very weak antigenic potential and probably would not induce systemic allergic reactions in clinical uses.

Cimicifuga racemosa (Black cohosh) has been used as therapeutics for pain and inflammation in Korean folk medicine. The potential effects of cimicifuga racemosa extract on mast cell dependent allergy reaction, however, have not been well elucidated yet. In the present study, we investigated the effect of cimicifuga racemosa extract on the allergy reaction using mast cell dependent in vivo and in vitro models. The oral administration of cimicifuga racemosa extract showed inhibitory potential on the compound 48/80 induced active systemic anaphylactic shock. cimicifuga racemosa extract also significantly inhibited the anti DNP IgE induced passive cutaneous anaphylaxis (PCA) reaction and acetic acid induced vascular permeability. In addition, cimicifuga racemosa extract inhibited the beta hexosaminidase release and TNF alpha and IL 4 mRNA induction by DNP HSA in rat leukemia mast cells, RBL 2H3. but cimicifuga racemosa extract didn't affected to RBL 2H3 cell viability. These results demonstrated that cimicifuga racemosa extract has an anti allergic potential and it may be due to the inhibition of histamine release and cytokine gene expression in the mast cells.

Basophils and mast cells are specialized effector cells in allergic reactions. Haliotis discus hannai (abalone), is valuable seafood. Abalone male viscera, which has a brownish color and has not been previously reported to show anti-allergic activities, was extracted with acetone. Six different acetone/hexane fractions (0, 10, 20, 30, 40, and 100%) were obtained using a silica column via β-hexosaminidase release inhibitory activity-guided selection in phorbol myristate acetate and a calcium ionophore, A23187 (PMACI)-induced human basophils, KU812F cells. The 40% acetone/hexane fraction (A40) exhibited the strongest inhibition of PMACI-induced-β-hexosaminidase release. This fraction dose-dependently inhibited reactive oxygen species (ROS) production and calcium mobilization without cytotoxicity. Western blot analysis revealed that A40 down-regulated PMACI-induced MAPK (ERK 1/2, p-38, and JNK) phosphorylation, and the NF-κB translocation from the cytosol to membrane. Moreover, A40 inhibited PMACI-induced interleukin (IL)-1β, IL-6, and IL-8 production. Anti-allergic activities of A40 were confirmed based on inhibitory effects on IL-4 and tumor necrosis factor alpha (TNF-α) production in compound (com) 48/80-induced rat basophilic leukemia (RBL)-2H3 cells. A40 inhibited β-hexosaminidase release and cytokine production such as IL-4 and TNF-α produced by com 48/80-stimulated RBL-2H3 cells. Furthermore, it's fraction attenuated the IgE/DNP-induced passive cutaneous anaphylaxis (PCA) reaction in the ears of BALB/c mice. Our results suggest that abalone contains the active fraction, A40 is a potent therapeutic and functional material to treat allergic diseases.

This report describes an inhibitory effect of Tongku-tang(TKT) on mast cell-mediated immediate-type allergic reactions. TKT is an Oriental herbal prescription, which has been successfully applied for the treatment of allergic disorders, mainly skin anaphylactic diseases in eastern medicine. TKT has concentration-dependently inhibited the ear swelling response induced by intradermal injection of non-specific mast cell degranulator compound 48/80 in mice. TKT also inhibited mast cell-dependent passive cutaneous anaphylaxis activated by dinitrophenyl (DNP)-IgE antibody in rats. I studied the effect of TKT on the histamine and β-hexosaminase release from the rat peritoneal mast cells by compound 48/80. TKT did not inhibit significantly the histamine and β-hexosaminase release from the rat peritoneal mast cells by compound 48/80. However, TKT inhibited both TNF-α and IL-1β secretion induced by phorbol 12-myristate 13-acetate and A23187 respectively. These results provide evidence that TKT may be beneficial in the treatment of immediate-type allergic reaction.

Gunjung-tang(GJT) has been reported at Shanghanlun(傷寒論), which has been used for the treatment of general weakness, digestive organ disease and the treatment of allergic disorders in clinical medicine. However, its effect in experimental models remains unknown. In a rat and mouse model, the role of GJT was examined in mast cell-dependent allergic reactions and secretion of inflammatory cytokines. GJT inhibited anti-dinitrophenyl IgE antibody-induced passive cutaneous anaphylaxis reaction by Intraperitoneal pretreatment. GJT inhibited both IL-1β and TNF-α secretion on egg albumin induced allergic tissues and compound 48/80 induced thymus. Furthermore, GJT enhanced Band T lymphocytes proliferation. Our findings provide evidence that GJT inhibits the IgE-dependent allergic reactions and inflammatory cytokines secretion, and enhanced immune response.
