The antigenicity of the aqueous extract of red ginseng (ARG) was evaluated using the following assay procedures : 1. active systemic anaphylaxis (ASA) in guinea pigs, 2 active cutaneous anaphylaxis (ACA) in guinea pigs, 3 passive cutaneous anaphylaxis (PCA) in guinea pigs, 2.active cutaneous anaphylaxis (ACA) in guinea pigs, 3. passive cutanepous anaphylaxis (PCA) in guina pigs with serum for guina pigs sensitized with ARG and 4. passive hemagglutination (PHA) with serum from guinea pigs sensitized with ARG. 1. ASA : No anaphylaxis reaction was observed in any of the sensitized guinea pigs by elictitation with ARG. 2. ACA : No skin reaction was observed in sensitized guinea pigs after intrademal injection of ARG. 3. PCA in guinea pigs : PCA titer of sera from all the sensitized animals was less than 10 in eliciation with ARG. 4. PHA reaction : When eythrocytes coated with challenge antigen were added to sensitized sera, the hemagglutination titer was less than 1. These results suggest that ARG has no antigenicity under the conditions used. And the dose levels of ARG employed in the present experiment were confirmed not to suppress immune reactions.

Aqueous extreact of fresh ginseng (AFG) was examined for the antigenicity in Hartley guinea pigs in comparision with ovalbumin (OVA). When guinea pigs were sensitized with AFG emulsified with complete Freund's adjuvant (CFA), these animals showed negative reactions in active systemic anaphylaxis (ASA), active cutaneous anaphylaxis (ACA) and passive cutaneous anaphylaxis (PCA) tests and passive hemagglutination (PHA) reaction. On the contrary, when guinea pigs were sensitized with OVA emulsified with CFA as positive controls, these animals disclosed positive reactions in ASA, ACA and PCA tests and PHA reaction. From these results, AFG was considered not to possess antigenic properties in guinea pigs. In addition, the dose levels of AFG empolyed in the present experiment were confirmed not to suppress immune reactions.

To evaluate the antiatopic effect of Korea Red Ginseng (RG, steamed root of Panax ginseng C.A. Meyer, Family Araliaceae), its inhibitory effect on passive cutaneous anaphylaxis reaction and itching in mice was measured. RG and its ingredient saponin fraction (SF) potently inhibited passive cutaneous anaphylaxis (PCA) reaction and scratching behaviors. RG at a dose of 100 mg/kg and SF at a dose of 50 mg/kg significantly inhibited the scratching frequency by 32% and 38%, respectively. RG and SF also inhibited the degranulation and protein expression of tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-4 of RBL-2H3 cells induced by IgE-antign complex. However, polysaccharide fraction of RG did not inhibit it. Based on these findings, RG can improve allergic skin disorders atopic dermatitis and contact dermatitis by the regulation of $TNF-{\alpha}$, and IL-4 produced by mast cells and basophils and their membrane stabilization.

To evaluate the antiallergic effect of the dried root of Astragalus membranaceus Bunge (AM) (Leguminosae), which inhibited the mouse passive cutaneous anaphylaxis (PCA) reaction in a preliminary experiment, its main constituents, astragalosides I and IV, were isolated and their antiallergic effects were investigated. Astragalosides I and IV inhibited the PCA reaction induced by the IgE-antigen complex, and the scratching behaviors induced by compound 48/80. These constituents reduced the protein expressions of $TNF-{\alpha}$ and IL-4 in IgE-induced RBL-2H3 cells. These findings suggest that astragalosides I and IV as well as AM can improve IgE-induced anaphylaxis and scratching behaviors.

To evaluate the antiatopic effect of Korea red ginseng (RG, steamed root of Panax ginseng CA Meyer, Family Araliaceae) fermented by Bifidobacterium longum H-1 (FRG), its inhibitory effect on passive cutaneous anaphylaxis (PCA) reaction and itching in mice was measured. FRG and its ingredient saponin fraction (FSF) potently inhibited PCA reaction and scratching behaviors. FRG at a dose of 200 mg/kg and FSF at a dose of 50 mg/kg significantly inhibited the scratching frequency by 45% and 47%, respectively. FRG and FSF also inhibited the degranulation and protein expression of tumor-necrosis $factor-{\alpha}$ and interleukin-4 of RBL-2H3 cells induced by IgE-complex. However, polysaccharide fraction of FRG (FPF) weakly inhibited it, compared with FSF. The inhibitory effect of FRG against PCA reaction and scratching behaviors more potently inhibited than that of RG. Based on these findings, FRG can improve allergic skin disorders atopic dermatitis by the regulation of $TNF-{\alpha}$, and IL-4 produced by mast cells and basophils and its degranulation.

Antigenic potential of a novel cephalosporin, IDC7181 was examined a active systemic anaphylaxis (ASA) and passive cutaneous anaphylaxis (PCA) test, in guinea pig and mouse-rat models, respectively. In ASA test, IDC7181 induced the signs of restlessness in a few animals immunized with a high dose (100 mg/kg) of IDC7181 alone or in combination with Freund's complete adjuvant (FCA). In PCA test, only one of ten sera from the animals immunized with a high dose (100 mg/kg) of IDC7181 in the absence or presence of FCA showed positive reaction. The positive reaction, induced by IDC7181, which may be due to $\beta$-lactam ring, in ASA and PCA tests were negligible in comparison with those of traditional cephalosporins. Taken together, it is suggested that IDC7181 do not cause immunological problems in clinical dosage.

The aqueous extract of Siegesbeckia pubescens (SPAE) inhibited compound 48/80-induced systemic anaphylaxis 100% with the dose of 1.0, 0.5 mg/g body weight (BW) at 1 h before or 5 min, 10 min after intraperitoneal injection of compound 48/80. The passive cutaneous anaphylaxis (PCA) reaction also inhibited to 78.5% by oral administration of SPAE(1.0 mg/g BW). When SPAE pretreated on mice at concentrations ranging from 0.0001 to 1.0 mg/g BW, the serum histamine levels were reduced in a dose-dependent manner. Moreover, SPAE ($100-800{\mu}g/ml) dose-dependently inhibited the histamine release from peritoneal mast cells (RPMC) by compound 48/80 $(5{\mu}g/ml)$. Analysis by microscopic appearance observation revealed that SPAE $(500{\mu}g/ml) stabilized the RPMC membrane. Therefore, these findings indicate that SPAE inhibits anaphylactic reactions through stabilization of mast cell membrane.

Complementary and alternative medicines are considered as a promising research field to develop new therapies for various allergic diseases. In this study, we investigated the anti-allergic effect of Agrimonia pilosa Ledeb (AP) by using passive cutaneous anaphylaxis in mice and its mechanism of action in mast cells. The extract of AP reversibly inhibited degranulation in RBL-2H3 cells and bone marrow-derived mast cells (BMMCs). AP also suppressed the passive cutaneous anaphylaxis inducing by IgE and antigen (Ag) in a dose-dependent manner. In the study to find its mechanism of action, AP inhibited the phosphorylation of Syk kinase, a pivotal protein which is regulated by Src-family kinase for activation of mast cells. In addition, AP also suppressed activation of Akt and Erk1/2 that are critical for the production of cytokines in mast cells. The results strongly suggest that AP exerts anti-allergic activity in vitro and in vivo through the inhibition of activation of Syk in mast cells.

Artemisia princeps Pampanini, which is called Ssajuarissuk in Korean (SS-1), was fermented with lactic acid bacteria (LAB) and their passive cutaneous anaphylaxis reaction-inhibitory activity was investigated. Of these fermented agents, SS-1 extract fermented with Bifidobacterium infantis K-525 (F-SS-1) most effectively inhibited the release of ${\beta}$-hexosamindase from RBL-2H3 cells induced IgE. In IgE-induced RBL-2H3 cells, F-SS-1 inhibited proinflammatory cytokines IL-6 and $TNF-{\alpha}$ mRNA expression. Oral administration of SS-1 and F-SS-1 to mice inhibited passive cutaneous anaphylaxis (PCA) reaction induced by IgE and scratching behaviors induced by compound 48/80. The inhibitory activity of F-SS-1 against scratching behaviors was more effective than that of SS-1. These findings suggest that the fermentation of SS-1 with LAB can increase its antiallergic activity.

This study was conducted to investigate antigenic potential of DA-3030, a recombinant human granulocyte-colony stimulating factor, in guinea pigs and mice. In the active systemic anaphylaxis test, the guinea pigs sensitized with 1.25 or 12.5 $\mu\textrm{g}$/head of DA-3030 alone did not show any anaphylactic reaction. In the homologous passive cutaneous anaphylaxis reaction, anti-DA-3030 antibody was not detected in guinea pigs sensitized with 1.25 or 12.5 $\mu\textrm{g}$/head of DA-3030 alone. On the other hand, the guinea pigs sensitized with 12.5 $\mu\textrm{g}$/heed of DA-3030 incorporated in Freund's complete adjuvant(FCA) or 1 mg/head of ovalbumin incorporated in FCA showed anaphylactic reaction. Anti-DA-3030 antibody was also detected in those guinea pigs. In immunodiffusion test using the sera sensitized with DA-3030 incorporated in FCA, precipitating antibodies were detected only in the sera sensitized with DA-3030 or DA-3030 incorporated in FCA showed. In 24-hour heterologous PCA reaction with sera of C57BL/6 mice immunized with 1.25 or 12.5 $\mu\textrm{g}$/head of DA-3030 alone, none of the sera showed positive reaction. But sera of the animals immunized with 12.5 $\mu\textrm{g}$/head of DA-3030 incorporated in aluminum hydroxide gel(Alum) or 5 $\mu\textrm{g}$/head of ovalbumin incorporated in alum showed positive PCA reaction. DA-3030 did not cause anaphylactic shock or passive cutaneous anaphylaxis in guinea pigs and mice when given alone although DA-3030 incorporated in FCA or Alum induced anaphylactic shock and passive cutaneous anaphylaxis. From these results, it may be concluded the DA-3030 does not induce systemic allergic reaction when administered alone in its clinical use.
