Mast cells play a key role in IgE-mediated allergic response. We investigated whether Swertia pseudochinensis Hara extract (SPE) inhibits IgE-mediated allergic response in mast cells and an allergic animal model. Additionally, we explored SPE's mechanism of action in mast cells. Our results showed that SPE inhibited both antigen-stimulated degranulation and the production of TNF-α and IL-4 in bone marrow-derived mast cells (BMMCs) and rat basophilic leukemia (RBL)-2H3 cells. SPE also suppressed allergic response in IgE-mediated passive cutaneous anaphylaxis (PCA) in mice. As for the mechanism of action of SPE in mast cells, it inhibited the activation of Syk kinase, a critical signaling protein in the FcεRI-mediated signaling pathway, and also the activation of LAT, a downstream adaptor protein of Syk. We further observed the reduced activation of mitogen-activated protein (MAP) kinases (P38, ERK1/2, and JNK) and Akt in mast cells. Our results described for the first time that SPE has an anti-allergic effect by suppressing mast cells through the inhibition of Syk kinase. Therefore, SPE may be useful for the treatment of type I allergic diseases.

The purpose of this research was to investigate the effect of Yonggak-san (YGS) on the anti-allergic reaction in vivo and in vitro. Administration of YGS(500 mg/kg) enhanced hemaggutination(HA)titer against SRBC. On the while, YGS inhibited hyaluronidase activity in vitro and passive cutaneous anaphylaxis reaction, lethal anaphylaxis and mortality induced by compound 48/80 in mice, YGS decreased Arthus reaction, acute hind paw edema induced by histamine. But YGS did not affect delayed type hypersensitivity induced by SRBC. These results suggest that YGS have anti-allergic action

Immunologic potential of DA-125, a new anthracycline antitumor antibiotic, was investigated using guinea pigs and mice. In antigenicity experiments, guinea pigs were sensitized subcutaneously with DA-125 or DA-125 incorporated in complete Freund's adjuvant (CFA) once a week for three weeks. No systemic anaphylaxis was induced by intravenous injection of DA-125 or DA-125 incubated with guinea pig serum after 3 weeks from the last sensitization. None of sera of these animals showed any passive cutaneous anaphylactic reaction (PCA) when DA-125 or DA-125 incubated with guinea pig serum was used as a challenging antigen in homologous PCA experiment. On the other hand the treatment of guinea pigs with ovalbumin Incorporated in CFA induced systemic anaphylactic reaction when challenged by intravenous injection of 5 mg/body of ovalbumin. Immunodiffusion test revealed no precipitating antibodies as detected in guinea pigs sensitized with DA-125. In 24-hour heterologous PCA reaction with sera of C57BL/6 mice immunized with DA-125 or DA-125 mixed with aluminum hydroxide gel (Alum), None of sera showed positive reaction when DA-125 or DA-125 incubated with rat serum was used as a challenging antigen. Sera of animals immunized with a mixture of ovalbumin and alum showed positive PCA reaction when 5 mg/body of ovalbumin was injected as a challenging antigen. In lymphocyte proliferation tests, spleen lymphocyte proliferation to PHA and LPS was similarly impaired by 12 mg/kg of DXR or 36 mg/kg of DA-125, and the immunodepressive activity of DA-125 showed a dose-dependent manner. From these results, it could be concluded that immunosupression of DA-125 would be comparable to that of DXR and that DA-125 would not induce systemic allergic reaction in its clinical use.

To evaluate the antiallergic effect of fermented Ixeris sonchifolia (IS, family Compositae), we prepared IS kimchi, isolated lactic acid bacteria (LAB) from it, fermented IS with these LAB, and investigated their antiallergic effects. IS kimchi inhibited the passive cutaneous anaphylaxis (PCA) reaction induced by an IgE-antigen complex as well as the scratching behavior induced by compound 48/80 or histamine more potently than IS. When IS was fermented with LAB isolated from IS kimchi, its antiallergic effects was also increased. Of LAB used for fermentation, Lactobacillus brevis more potently increased the antiallergic effects. Its main constituents, chlorogenic acid and luteolin, potently inhibited the PCA reaction induced by the IgE-antigen complex as well as the pruritis induced by compound 48/80 or histamine. These constituents inhibited the expression of pro inflammatory and allergic cytokines, TNF-$\alpha$. and IL-4, and transcription factor NF-${\kappa}B$ activation induced by the IgE-antigen complex in RBL-2H3 cells, as well as the degranulation of RBL-2H3 cells induced by the IgE-antigen complex. Luteolin more potently inhibited these allergic reactions than chlorogenic acid. These findings suggest that the antiallergic effect of IS can be increased by LAB fermentation, and the fermented IS might improve allergic reactions such as pruritus, anaphylaxis, and inflammation.

To understand the anti-allergic mechanism of compound K, which is a metabolite of ginsenoside Rb1, a main constituent of the root of Panax ginseng C.A. Meyer (family Araliaceae), its inhibitory effect against IgE-antigen complex IAC)-induced passive cutaneous anaphylaxis (PCA) reaction in mice and mRNA and protein expressions of allergic cytokines in lAC-stimulated RBL-2H3 cells were investigated. Orally administered ginsenoside Rb1 more potently inhibited PCA reaction when administered at 5 h prior to the lAC treatment than when administered at I h before. However, compound K orally administered 1 h before lAC treatment showed a more potent anti-PCA reaction effect than when treated at 5 h before. Orally administered ginsenoside Rb1 more potently inhibited PCA reaction induced by lAC in mice than intraperitoneally treated one, apart from orally administered its metabolite, compound K, which was more potent than the orally administered one. The compound K, a metabolite of ginsenoside Rb1, inhibited mRNA and protein expressions of IL-4 and TNF-${\alpha}$ and the activation of their transcription factor NF-$\kappa$B and MAPK in lAC-stimulated RBL-2H3 cells. These findings suggest that orally administered ginsenoside Rb1 may be dependent on its metabolism by intestinal microflora in the intestine and the compound K may improve allergic diseases by the inhibition of IL-4 and TNF-${\alpha}$ expresseion.

In this research the results showed that Evans blue stain causes vascular permeation at antibody injection site by the passive cutaneous anaphylaxis(PCA) screening of octpus minor so we concluded. Octopus minor causes allergy. Psedosciaena Polyactis, Raja Kenojei, Metapenaeus joyneri also showed allergenicity. Microwave and autoclaving appeared to reduced allergenicity(up to 99%) during the technological treatment processing. On the other hand, UV light didn't seem to change the protein structure of allergens affect the allergenicity. Therefore, the technological treatment processing of fish such as canning and microwave would possibly reduce the allergenicity. Among the ultrafiltration fraction of Octopus minor, Pseudosciaena Polyactis, Raja Kenojei and Metapenaeus joyneri, those fraction over 100,000 contained allergen and those under 100,000 and when screening allergenic fish went through 10,000∼100,000 ultrafiltration, only the fraction of over 100,000 showed the anaphylactis activity for PCA. However whether screening fish would cause anaphylaxis in human or not is questionable. The future clinical experiment will verify this result with clinical experiment patients. 본 연구 결과로 낙지의 PCA검색으로써 항체주사 부위에 Evan's Blue 착색으로 인하여 vascular permation이 일어나 allergynicity 반응이 인정되므로 낙지는 allergy가 있다고 할 수 있다. 조기, 홍어, 새우도 역시 allergenicity성이 나타난 것을 볼 수 있었다. 또한 공정 중 microwave와 autoclaving은 4가지 수산식품 낙지, 조기, 홍어, 새우의 allergenicity를 현저히 감소시키는 것으로 나타났다. 반면에 자외선은 단백질로 구성된 allergen의 구조는 크게 변화시키지 못하는 것으로 보여진 것을 알 수 있다. 그러므로 생선의 가공방법은 통조림 가공이나 microwave 처리가 allergenicity성을 감소시킬 수 있는 것으로 보여진다. 낙지, 조기, 홍어, 새우의 한외여과 fraction중 고분자인 100,000이상에서만 allergenicity가 나타났다. 따라서 이 allergen들의 분자량은 100,000 이상으로 추정되며 검색된 allergynicity 생선을 10,000∼100,000으로 한외여과 하였을 때 100,000 이상의 fraction에서만 PCA에 의해 allergenicity가 있는 것으로 인정되었다. 그러나 이 검색된 생선이 anaphylaxis가 인간에게서까지도 반응할지는 의문이다. 이 연구의 결과는 차후 임상실험환자에 의하여 최종 검증되어야 한다.

The purpose of this research was to investigate effects of Hyunsamchungpye-eum(HSCPE) on the anti-inflammatory/anti-allergic reaction in vivo and in vitro. HSCPE reduced the acute hind paw edema induced by histamine, the permeability of evans blue into peritoneal cavity. HSCPE inhibited the passive cutaneous anaphylaxis reaction in rat, the lethal anaphylaxis and degranulation of peritoneal mast cells induced by compound 48/80 in mice, HSCPE did not affect the Arthus reaction, but decreased the delayed type hypersensitivity induced by SRBC, contact dermititis induced by DNFB. These results suggest that HSCPE have an anti-inflammatory and anti-allergic action.

The antigenicity of EPO (erythropoietin) was investigated in guinea pig, mice and rats. Antigenicity tests-active systemic anaphylaxis (ASA), passive cutaneous anaphylaxis (PCA) of this materials were performed according to the established Regulation of Korean National Institute of Safety Research (1996, 4, 16). The results were followed: 1. After sensitizaion with EPO emulsified with complete Freund's adjuvant (CFA), guinea pigs didn't show any anaphylatic shock symptom in the ASA test 2. After sensitization with antisera of EPO sensitized mice, blue spots were observed on the hypodermis of back of rats in the PCA test, but diameter of each spot was smaller than 5 mm. From the results of this investigation, the antigenicity of EPO was negative under the present experimental condition.

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).

Antigenic potential of genetically-engineered human erythropoietin (EPO) was assessed in guinea pigs (active systemic anaphylaxis [ASA] ; passive cutaneous anaphylaxis [PCA]) and in vitro (hemagglutination test [PHA]). In ASA, EPO at 70~700 U/kg elicited a weak anaphylactic response tvhereas the positive control ovalbumin (OVA) did cause intensive responses leading to death in 40% animals. However, the extract of CHO cells, to which EPO gene was introduced, did not cause any symptom. In PCA and PHA tests, neither EPO nor CHO cell extract induced positive responses. OVA, in contrast, produced high titers in both PCA and PHA tests. It was concluded that, in light of the fact that EPO was slightly antigenic only in ASA but not in PCA or PHA and also that human EPO is a foreign protein to guinea pigs, the present EPO may not be antigenic in humans.
