Spirodela polyrhiza(L.) Schleid (Lemnaceae) have been used as a traditional drug in treating urticaria and itching. However, the exact role of Spirodela polyrhiza in allergic reaction has not been clarified yet. Type 1 hypersensitivity (immediate hypersensitivity), popularly known as allergy, is a major clinical problem in humans. It has been found that the histamine release from mast cells is an essential step in the pathological process of immediate hypersensitivity. In the present study, the effect of aqueous extract of Spirodela polyrhiza (AESP) on immediate hypersensitivity was investigated. AESP inhibited the antigen-induced passive cutaneous anaphylaxis (PCA). AESP in vitro exhibited a dose-dependent inhibition of degranulation in RPMC stimulated by compound 48/80. AESP also suppressed the morphological changes and the increase of intracellular free calcium level induced by compound 48/80. These results suggest that inhibitory effect of AESP on immediate hypersensitivity may be mediated through the decrease of intracellular free calcium levels, and AESP importantly contributes to the treatment of anaphylaxis and may be useful for other allergic disease.

Object : We investigated the effect of Gamiokyaek-tang(GOYT) on immediate type hypersensitivity. Methods : We investigated anti-dinitrophenyl(DNP) IgE-mediated passive cutaneous anaphylaxis(PCA) and acetic acid-induced vascular permeability in rodents. Also we measured MTT assay, ${\beta}-hexosminidase$ activity and IL-4 from RBL-2H3 and nitric oxide from Raw264.7. Results : GOYT inhibited passive cutaneous anaphylaxis and acetic acid-induced vascular permeability by oral administration. All the concentrations of GOYT from 0.1 to 5mg/ml didn't have an effect on cell viability and cytotoxicity. In RBL-2H3, ${\beta}-hexosminidase$ release and IL-4 production were significantly reduced by 1, 2 and 5mg/ml of GOYT. In Raw264.7, nitric oxide level was decreased by 5mg/ml of GOYT. Conclusion : These results indicate that GOYT have inhibition effects on immediate type hypersensitivity.

$80^{\circ}C$에서 30% 주정으로 추출된 소엽추출물 분말의 로즈마린산 함량은 12.3 mg/g이었으며, 소엽 30% 주정추출물분말(PF-E30)은 생쥐모델 실험에서 ant-DNP IgE으로 활성화된 local allergy 반응과 compound 48/80으로 유도된 mast cell-mediated immediatetype allergy 반응에 대한 억제 효과를 나타내었다. 더욱이, PFE30(0.1-0.5 mg/kg BW)의 투여는 혈장 히스타민 수준을 유의성있게 감소시켰으며, compound 48/80 또는 anti-DNP IgE으로 활성화된 복막 비만세포로부터 히스타민 방출을 억제하였다. 특히 PFE30는 antigen-induced IgE 의 생산을 농도 의존적으로 억제하였다. 이런 결과는 소엽 주정추출물이 in vivo 및 in vitro 실험에서 mast cell-mediated immediate-type allergy 반응을 저해한다는 것을 제시한다. 소엽 주정추출물이 알레르기 반응을 억제하는 기능성 식품 소재로서의 개발을 위해서는 mast cell mediated-type allergy 반응에 대한 보다 많은 연구가 필요할 것이다.

Shini-San has been used for treatment of allergic disease in Korea. However, its effect in experimental models remains unknown. The mast cell plays a pivotal role in initiating al1ergic response by secreting intracytoplasmic granular mediators such as histamine. The present report describes an inhibitory effect of Shini-San on mast cell-mediated immediate-type al1ergic reactions. Topical application of compound 48/80 can induce an ear swelling response in normal ($WBB6F_1-+/+$) mice but not in congenic mast cell-deficient $WBB6F_1-W/W^v$ mice. Shini-San inhibited concentration dependent mast cell-dependent ear swelling response induced by compound 48/80 in normal mice. Shini-San inhibited concentration-dependent passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP) immunoglobulin E (IgE) in rats by topical application. Shini-San also inhibited in concentration-dependent fashion the histamine release from the rat peritoneal mast cells by compound 48/80 or anti-DNP IgE. Moreover, Shini-San had a significant inhibitory effect on compound 48/80-induced systemic anaphylactic reaction. These results indicate that Shini-San inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.

Objective : To investigate the effect between Fructus Immaturus Ponciri (FIP, the immature fruit of Poncirus trifoliata) and Fructus Ponciri (FP, the ripe fruit of Poncirus trifoliata) on mast cell-mediated immediate-type allergic reactions. Methods : We performed anaphylactic reaction, histamine release, cAMP, $TNF-{\alpha}$, IgE. Results : The aqueous extract of FIP dose-dependently inhibited systemic and local allergic reaction was induced by compound 48/80 or anti-dinitrophenyl (DNP) IgE in a murine model. FIP also significantly inhibited mast cell-dependent ear swelling response induced by topical application of compound 48/80. When mice were orally pretreated with FIP, the plasma histamine levels were reduced in a dose-dependent manner. FIP dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) was activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when FIP was added, increased compared with that of a normal or control. In addition, FIP had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-a ($TNF-{\alpha}$) production from the RPMCs and IgE produced by lipopolysaccharide-stimulated murine whole spleen cells or U266B1 as human IgE-bearing B cells. However, FP showed the lower inhibition rate than those of FIP in above all allergic reactions. Conclusion : These data have important implications for our understanding of the clinical effects of FIP and FP on allergic diseases, and FIP is more effective than FP on the allergic reaction.

Cloves are the dried flower buds of Syzygium aromaticum (L.) Mere et Perry (Myrtaceae). They have been successfully used for the management of various allergic disorders by oral administration in Korea. In this study, the author investigated the effect of an aqueous extract of Syzygium aromaticum on immediate-type hypersensitivity by anal administration. Anal administration of Syzygium aromaticum showed a marked inhibition rate in systemic hypersensitivity with a dose of 1 mg/kg 1 hr before intraperitoneal injection of compound 48/80. Anal administration of Syzygium aromaticum significantly reduced plasma histamine contents induced by compound 48/80. Anal administration of Syzygium aromaticum (1 mg/kg) also inhibited to $61.4\%$ (P<0.01) local a1lergic reaction activated by anti-dinitrophenyl (DNP) IgE. In addition, Syzygium aromaticum dose-dependently inhibited the histamine release from the peritoneal mast cells by compound 48/80 or anti-DNP IgE. When Syzygium aromaticum was added, the level of cAMP in peritoneal mast cells transiently and significantly increased about 47-fold at 10 second compared with that of basal cells. These results provide evidence that anal therapy of Syzygium aromaticum may be beneficial in the treatment of systemic and local immediate-type hypersensitivity by inhibition of histamine release from mast cells in vivo and in vitro.

Objective : Mast cells are a potent source of mediators that regulate inflammatory response in allergies and asthma. The author studied the effect of Bojungikgitanggamibang(BITB) on mast cell-mediated anaphylactic reaction. Method : When BITB was given as pre-treatment at concentrations ranging from 0.01 to 1 mg/ml, the histamine release from rat peritoneal mast cells induced by compound 48/80 was reduced in a dose-dependent manner. Result : BITB dose-dependently inhibited compound 48/80-induced systemic anaphylactic shock. BITB also inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl IgE. In addition, BITB inhibited phorbol 12-myristate 13-acetate and A23187-induced interleukin-6 secretion from human mast cell line HMC-1 cells. Conclusion : These results indicate that BITB may be actively anti-allergic.

Objectives : This study was performed to compare the effect of two Cudrania tricuspidata cultivars; Sancheong native (CT) and varieties in china(SCT) on immediate hypersensitivity of the anaphylactic type and Ova-induced allergic asthma mouse model by calculating serum cytokines and IgE. Methods : We investigated the free radical scavanging effect and quantify total phenol contents and total flavonoids of two Cudrania tricuspidata cultivars; Sancheong native(CT) and varieties in china(SCT). The sample was extracted by 80% EtOH. To induce the allergic asthma, in the control group and the CT group, mice of each group were sensitized intraperitoneally with ovalbumin (OVA) solution at the 1st, the 7th and the 14th day. After then, sensitization was performed by aerosol allergen challenges with 1% OVA solution intratracheally at the 21th, the 23th, 25th and the 27th day. At the 29th day, the mice were killed and the changes of interferon-${\gamma}$, interleukin-4, 5 and 10, total IgE and OVA-specific IgE in serum were checked. Results : CT inhibited compound 48/80-induced systemic anaphylaxis 90% with a dose of 100 mg/kg body weight at 1 hr before injection of compound 48/80. In the allergic asthma mouse model, IFN-${\gamma}$ was did not increased in the CT and SCT group than that in the control group. IL-4, IL-5, the total IgE and OVA-specific IgE were decreased in the CT group as compared with the control group and these results were statistically significant. Conclusions : Considering the above experimental results, this study showed that Sancheong native cultivar could reduce the allergic reaction.
