During the screening program to discover antiatopic agents from herbal formulas, we investigated the inhibitory effect of Hwangryunhaedoktang (HT) on passive cutaneous anaphylaxis and oxazolone-induced mouse ear dermatitis. HT significantly inhibited PCA reaction in mice at doses of 50 and 200 mg/kg with inhibitory activity of 31 and 53%, respectively. HT at concentration of 0.05 and 0.1% inhibited ear swelling by 23 and 46% at 16 days in oxazolone-induced mouse ear dermatitis. Both HT with anti without human intestinal microflora showed potent inhibitory activity on the ${\beta}$-hexosaminidase release induced by IgE. Based on these findings, HT may be a usable agent for skin disorder contact dermatitis.

HM10760 is a recombinant human erythropoietin that has beer developed as a drug for anemia. In this study, antigenic potential of HM10760 was examined by active systemic anaphylaxis in guinea pigs and passive cutaneous anaphylaxis in a guinea pig-guinea pig system. HM10760 was subcutaneously administered at 0, 2, and $20{\mu}g/kg$ and also as a suspension with adjuvant ($20{\mu}g/kg$ + FCA). Ovalbumin as a suspension with adjuvant was administered to induce positive control responses. In the active systemic anaphylaxis test, no symptoms except rubbing or licking nose and urination that were considered as physiological phenomena were observed at $0{\mu}g/kg$. Four of 5 animals at $2{\mu}g/kg$ and all the 5 animals at $20{\mu}g/kg$ showed cyanosis and lying on side. All animals in the adjuvant mixture group showed relatively mild symptoms such as rubbing or licking nose, urination, and evacuation. In the passive cutaneous anaphylaxis test, 0/5, 3/5, and 5/5 serum samples from the animals immunized with 0, 2, and $20{\mu}g/kg$, respectively, showed positive reactions against HM10760. All 5 sera collected from the animals immunized with an adjuvant mixture contained HM10760-specific antibodies. These results suggest HM10760 have antigenicity in guinea pigs.

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.

Objectives : The purpose of this study was to examine the anti-allergic effect in vivo, and to observe single toxicity in mice of Armeniacae Semen herbal acupuncture solution (ASHA). Methods : We investigated anti DNP IgE-mediated passive cutaneous anaphylaxis in rodents and compound 48/80-induced active systemic anaphylatic shock in mice after treatment at both BL13 with ASHA of 25 ${\mu}{\ell}$(mice) or 50 ${\mu}{\ell}$(rats) 3 times for 5 days. To ascertain safety and toxicity of ASHA, we examined single toxicity test. In single test, three groups were treated with different dosages of ASHA (ASHA250, ASHA500 and ASHA1000) according to on Korean Food and Drug Administration, respectively. We observed attentively motality, abnormal clinical sign, body weight change, and organ weight of mice after ASHA treatment. Results : ASHA inhibited passive cutaneous anaphylaxis and active systemic anaphylatic shock by oral administration. During toxicity experiment period, there was no difference in body weight change, and organ weight among different dose groups. Death were not found in single test i.p. group. (ASHA250, ASHA500 and ASHA1000). Several individuals of single test i.p. group were observed yellow brown discharge around anus in early period after administration. Conclusions : These results indicate that ASHA have inhibition effects on passive cutaneous anaphylaxis and active systemic anaphylatic shock, and suggest that has some toxicity in high dosage.

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.

Effects of Panax ginseng on allergic reactions were studied uslng various in vivo and in vitro experimental models such as 48-hr passive cutaneous anaphylaxis, mediators-induced skin reactions, histamine release from rat peritoneal mast cells, hexosaminidase release from RBL-2H3 cells, and lipoxygenase assay . In all of anti-allergic experiments we conducted, ginseng components (50% ethanol extract or ginseng total saponin or ginsenosides) extracted from Korean red ginseng, did not show significant anti-allergic actions. In 48-hr passive cutaneous anaphylaxis and mediators-induced skin reactions, 50% ethanol extract did not suppress hypersensitivity reactions. Total saponin, 50% ethanol extract, and 8 major ginsenosides did not show inhibitory effects on lipoxygeanse activity. Ginseng total saponin did not inhibit histamine release from rat peritoneal mast cells. All of the ginseng components mentioned above were also tested on RBL-2H3 cells, but none of them inhibited hexosaminidase release from this cell line. These results suggest that Panax ginseng does not have effects on allergic reactions at the level of 50% ethanol extract or total saponin used. All of 8 major saponin components tested ($Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, $Rg_2$), did not inhibit lipoxygenase activity and degranulation events.

제 1형 과민반응은 비만세포에 의해 매개되는 알러지 반응으로서, 예기치 못한 알러젠에 의해 비만세포가 활성화 되어 탈 과립 되면서 히스타민등과 같은 여러 가지 매개체들을 분비하면서 과도하게 면역반응을 유도하게 된다. 주박(Korean rice wine lees)은 청주, 약주 등의 술을 걸러내는 과정에서 생기는 양조 부산물로서, 최근들어 청주를 걸러내는 과정에서 생기는 술 지게미의 생리기능에 대한 연구가 활발하게 진행되고 있다. 본 연구에서는 주박의 ethyl acetate (EA) 추출물을 이용하여 비만세포에서의 탈과립 억제 효과를 측정하였다. 그 결과 주박 EA 추출물이 탈과립의 표지인 ${\beta}$-hexosaminidase의 양을 농도 의존적으로 억제하는 것을 관찰하였고, 이러한 탈과립억제 현상이 다양한 사이토카인 중 IL-3과 IL-13의 양을 감소시킴으로써 매개된다는 사실을 RT-PCR을 통해 확인하였다. 또한 쥐에서 passive cutaneous anaphylaxis (PCA)를 유도하여 EA를 경구투여 했을 때 anaphylactic 증상을 효과적으로 억제하는 것을 관찰하였다. 이러한 결과들은 주박 EA 추출물이 항 알러지 약물의 개발에 잠재적인 후보물질이 될 수 있음을 시사한다.

We studied the inhibitory effect of Green Life Enzyme (GLE) on compound 48/80-induced anaphylactic response in a murine model. GLE inhibited compound 48/80-induced systemic anaphylactic shock at the dose of 10 g/kg by 87.5%. When GLE was given as pre-treatment at concentrations ranging from 0.01 to 1.0 g/kg, it inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. In addition, GLE (0.1 mg/ml) inhibited anti-DNP IgE-induced tumor necrosis $factor-{\alpha}$ production from mast cells by 69% compared to saline value. These results indicate that GLE may possess anti-anaphylactic and anti-inflammatory activity.

To study the antigenicity of BR92021(Vi polysaccharide typhoid vaccine), active systemic ana-phylaxis and passive cutaneous anaphylaxis were tested in guinea pigs. The groups were as follows: group I(low dose, 30 $\mu\textrm{l}$/kg), group II(high dose, 300 $\mu\textrm{l}$/kg), group III(300 $\mu\textrm{l}$/kg plus complete Freund's adjuvant), group IV(positive control, ovalbumin plus complete Freund's adjuvant) and group V(saline-treated control). Male Hartley guinea pigs at 7 weeks of age were sensitized subcutaneously with the test article or saline three times per week for three weeks(j.e., total 9 times). For groups III and IV, animals were sensitized subcutaneously with either the test article or ovalbumin plus complete Freund's adjuvant once per three week for 6 weeks(i.e., total 3 times). Twelve days after the last sensitization, the blood was collected from the sensitized animals for the passive cutaneous anaphylaxis test. In addition, the sensitized animals were subjected to the active systemic anaphylaxis test on fourteen days after the last sensitization by an intravenous challenge with either the test article or ovalbumin. In group I, mild(1/5) or moderate(4/5) symptoms of anaphylactic shock were observed. In group II, no sign(1/5), moderate(3/5) and severe(1/5) symptoms were observed. In group III, four animals of revealed moderate signs and one of 5 showed no signs of anaphylactic shock. In group IV, all 5 animals showed severe signs of shock. In group V, one of 5 revealed moderate and four of 5 showed no signs. The necropsy findings related to the active systemic anaphylaxis were observed in most animals of groups I to V In the passive cutaneous anaphylaxis test, the antiserum was diluted 10- to 5120- fold and was injected intradermally on the clipped back of recipient animals, followed by an intravenous challenge with either the test article or ovalbumin. No animals in groups I, II, III and V showed the positive reaction, whereas all animals in group IV, the positive control, showed the positive reaction at the dilution range of x1280 to x5120. Our results indicate that the test article, BR92021, may have weak antigenic potential in male guinea pigs.

난백의 알레르겐을 감소시키기 위해서 여러 가지 처리를 실시하고 처리난백의 알레르기성의 변화를 평가하고자 passive cutaneous anaphylaxis(PCA) test, immunoblot, 생쥐모델에 의한 알레르기 유발시험을 실시하였다. PCA test결과 열처리($121^{\circ}C$, 30 min)한 난백은 처리하지 않은 난백에 비하여 그 항원성이 1/8 정도로 감소되었으며, NaOH처리군은 0.3%와 1%에서 각각 1/4, 1/8로 항원성의 감소를 보였다. 특히, NaOH처리 후 열처리(70oC, 15 min)를 추가적으로 복합처리한 난백의 경우, NaOH 0.3%(w/v)에서는 1/8 정도로, NaOH 1%(w/v)에서는 1/32 정도로 강력하게 항원성이 감소되었다. 계란 알레르기 환자의 IgE 항체를 이용하여 immunoblot을 실시한 결과 121oC로 열처리한 시료에서 난백의 주요 단백질 band가 흐려지는 것으로 나타났고 NaOH와 열로 복합처리한 난백의 경우에도 NaOH 0.1%(w/v) 이상에서 band들이 대부분 소실되는 것으로 나타났다. 생쥐모델에 의한 시험을 실시한 결과, 난백으로 유도한 전신알레르기 증상의 평균점수는 1.85이었으나 복합처리한 난백의 경우 그 점수가 0.20로 현격하게 감소되었다. 결론적으로, 상기 3종의 시험에서 공통적으로 가장 효과적인 난백의 알레르기성 저감화 방법은 복합처리(NaOH(1%, w/v) 및 열($70^{\circ}C$, 15min))임이 확인되었다.
