Purpose : The objective of present study is to detect the effect of Sopungsan aqueous extracts (SPS) on the passive cutaneous anaphylaxis (PCA; type I allergic dermatitis) Method : 500, 250 and 125mg/kg of SPS were orally administered 12 hr-interval before antigen challenge (total 4 times administered). PCA reactions were induced using rat anti-ovalbumin (OVA) serum contain IgE (titer 1:32) as sensitization and OVA as antigen challenge. 30 min after antigen challenge, the diameter of blue-dye spots (evans blue) and leaked amount of dye were observed with histology and histomorphometry at the PCA induced sites. In addition, serum total IgE and histamine levels were also observed by ELISA, respectively. The effects of SPS were compared with dexamethasone 1mg/kg treated rats in the present study. Results : As results of PCA reaction, vasodilation related increase of diameter of blue-dye spot and amount of leaked dye were observed with swelling and edematous changes in the dermis of PCA induced sites. However, these changes on PCA reactions were dramatically and dose-dependently decreased by treatment of SPS as compared with vehicle control. In addition, serum elevations of IgE and histamine were also dose-dependently inhibited by treatment of SPS as compared with vehicle control respectively. The effects of SPS 500mg/kg were similar to that of dexamethasone 1mg/kg in the present study. Conclusion : Base on the results of the present study, it is concluded that SPS has favorable effect on the PCA-induced allergic dermatitis, and SPS 500mg/kg showed similar favorable effects as compared with dexamethasone 1mg/kg. The present findings demonstrate that SPS can be effective for the prevention and treatment of allergic dermatitis.

This study was investigated the anti-allergic effect of SJSBT on DNCB induced atopic dermatitis in NC/Nga mice. We summerized as the follow. SJSBT significantly decreased the clinical manifestations of atopic dermatitis including itching, dryness, edema, hemorrhage, and lichenification in dose dependent manner. SJSBT markedly suppressed invasion and edema of leukocytes and mast cell in dorsal skin and ear tissue. SJSBT significantly reduced the number of CD11b+/Gr-1 cell compared with positive control, but it had no affect the number of CD3+ and CCR3+/CD3+ cell. SJSBT markedly suppressed the expression of cytokine and chemokine such as IL-6, $TNF-{\alpha}$, eotaxin and CCR3 compared with positive control group. SJSBT significantly decreased the invasion of CD4+ and CCR3+ cell in ear and dorsal skin tissue compared with positive control group by using immunohistochemical staining. Taken together, these findings suggested that SJSBT has an anti-allergic activity and this might be useful for the clinical application to treat allergic diseases such as atopic dermatitis.

A 2-year-old spayed female Persian cat presented to Kangwon National University Veterinary Medical Teaching Hospital with pruritus and erythema on the tips of both ears, around the eyes, and in the caudal abdomen. This patient had previously been prescribed prednisolone, but did not respond positively to the treatment. A skin screening test revealed that there were no fleas or fungi, and that only cocci were present. Blood testing revealed no remarkable findings. The patient was prescribed antibiotics (amoxicillin-clavulanic acid 25 mg/kg for 2 weeks) with no prednisolone. After 2 weeks, clinical signs were alleviated and the skin screening test showed no signs of cocci. However, clinical signs recurred even with the prescription of antibiotics. Four weeks after the steroid-free interval, Malassezia spp. hypersensitivity was detected upon a serum allergy test, and pathological analysis confirmed eosinophilic and mastocytic superficial dermatitis in the caudal abdomen. Based on these results, we suspected allergic dermatitis and prescribed 7 mg/kg cyclosporine A once a day. After 3 weeks, clinical signs were resolved. Seven weeks after the first trial with cyclosporine A, we reduced the cyclosporine A dose to 7 mg/kg every other day. The patient's symptoms have since been well controlled for 6 months. This study suggests that cyclosporine A can be a good choice for treating cats with suspected allergic dermatitis that has not responded positively to steroid treatment.

Objectives : Allergic contact dermatitis(ACD) is a type IV delayed hypersensitivity reaction that results from cumulative exposures and subsequent sensitization to an environmental chemical. Lonicerae Caulis(LC) can clear away heat and relieve toxin, disperse wind and heat, dredge the channel. The present study was designed to investigate the effects of LC on allergic contact dermatitis(ACD) induced by 2,4-dinitrochlorobenzene(DNCB) in mice. Methods : In this experiment, the effects of LC on changes in body weights, ear and dorsum skin thicknesses, ear weights, clinical aspects on the dorsum skin, histopathological changes, spleen/body ratio, cytokines were investigated. In addition, the effects on proliferations of splenocytes were also investigated in vitro and vivo study. Results : LC spread(SPR) group and LC spread and administered(SPR+ADM) group showed diminished ear thicknesses. In SPR+ADM group, ear weights were lowered significantly compared to contact dermatitis control(CTL) group. LC treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. In histopathological observation, spongiosis and edema were diminished in SPR and SPR+ADM group. In cytokines, SPR+ADM group were increased in IL-10, and SPR and SPR+ADM group were decreased in TNF-${\alpha}$ compared with control group. Conclusions : These data suggest that LC can decrease symptoms of ACD, then LC is useful to treat patient with ACD.

This study was undertaken to investigate the therapeutic effect of Angelica acutiloba on allergic dermatitis, which Angelica acutiloba is traditionally known to have antiinflammatory effects. Sprague-Dawley (SD) rats were divided into five groups: normal control group, experimental allergic dermatitis group (vehicle group), low dose of Angelica acutiloba extract (low-dose group), high dose of Angelica acutiloba extract (high-dose group), and antihistamine treated group with experimental dermatitis (antihistamine group). Total leukocyte, neutrophil, lymphocyte, monocyte and eosinophil counts were significantly higher in the vehicle group than in the control group, but these variables were significantly lower in the low- and high-dose groups than in the vehicle group. The platelet/lymphocyte ratio in the red blood cell index was significantly lower in the low- and high-dose groups than in the vehicle group. Low and high doses of the Angelica acutiloba extract did not have toxic effects on liver and kidney. Serum NO, iNOS and levels were highest in the vehicle group but significantly lower in the low- and high-dose groups, especially in the high-dose group. The results of this study suggested that the Angelica acutiloba extract had the effect of alleviating or treating the experimental allergic dermatitis, and it was concluded that the high dose was more effective.

Black-red ginseng (BRGP) exhibits more potent biological activities than white and red ginseng. However, the effect of BRGP on allergic inflammation has not been studied extensively. In this study, we attempted to evaluate the effects of BRGP on allergic inflammation in vitro and in vivo. The effects of BRGP on pro-inflammatory mediators in phorbol myristate acetate (PMA) and A23187-stimulated human mast cells (HMC-1) and on trimellitic anhydride (TMA)-induced atopic dermatitis-like skin lesions in BALB/c mice were evaluated. BRGP suppressed the expression of $TNF-{\alpha}$, IL-6 and IL-8 from HMC-1 stimulated with PMA and A23187. Furthermore, the oral administration of BRGP markedly significantly reduced apparent severity of atopic dermatitis-like skin lesions, ear swelling, lymph node weight gains and serum IgE levels induced by TMA in mice. BRGP treatment also ameliorated epidermal hyperplasia and infiltration of inflammatory cells including mast cells. Taken together, BRGP possesses significant anti-atopic efficacy, suggesting that it could be used as a potential therapeutic agent for allergic inflammatory diseases, including atopic dermatitis.

Activated T helper 2 (Th2) immune function is hallmark of various allergic diseases. We investigated the anti-allergic effect of Jagamcho-tang extract(JE) on ovalbumin(OVA)-induced atopic dermatitis mice model and OVA-stimulated splenocytes isolated from the mice. Mice were intraperitoneally injected OVA/alum solution 2 times at interval of 14 days, followed by oral administration of JE for 7 days. After administration, mice were subcutaneously injected with OVA in ear. JE treatment reduced ear swelling and infiltration of inflammatory cells in ear. Serum levels of interleukin(IL)-4 and immunoglobulins, such as total-IgE and OVA-specific IgE, were decreased in JE treated group. Furthermore, JE treatment decreased OVA-induced Th2-associated cytokines like IL-4, IL-5 and IL-13 mRNA levels in splenocytes. In conclusion, JE reduced allergic immune response via IgE production and Th2 response in OVA-sensitized mice, suggesting that JE could be useful prescription for allergic diseases including atopic dermatitis.
