  • Objectives: The root of Lithospermum erythrorhizon Sieb. et Zucc. (Lithospermi Radix, LR) is a kind of heat clearing and blood cooling medicinal herbs. It can clear away heat and cool the blood, reduce toxins and disperse maculae. LR has long been used as efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we investigate anti-allergic and anti-inflammatory effects of LR by using the 1-fluoro-2, 4- dinitrofluorobenzene (DNFB)-induced contact dermatitis mouse model. Results: Topical application of 10 mg/mL of LR effectively inhibited skin lesions induced by repeated paintings with DNFB. Topical application of LR also inhibited hyperplasia, edema, spongiosis and infiltrations of mononuclear cells. In addition, production levels of total immunoglobulin and IgG1 in serum were decreased by using LR in vivo. Conclusions: These data suggest that LR acts as an antiinflammatory agent, improving skin lesions in CD mice.

  • Hataedock (HTD) treatment is a traditional preventive therapy for the fetal toxicosis- the acute allergic disease after childbirth, mainly manifested by a variety of skin allergies such as scab, phlegm. The aim of this study was to investigate the efficacy of HTD treatments for the alleviation of inflammation in Dermatophagoides farinae-induced obese NC/Nga mice. 20 mg/kg of Coptidis Rhizoma, Glycyrrhizae Radix (CRGR) extracts as a remedy of HTD treatments were orally administered to NC/Nga mice. We induced obesity in the mice by high-fat diet. To induce skin allergies, the extracts of Dermatophagoides farinae were topically applied on the NC/Nga mice at 4th-6th and 8th-10th weeks. Structural and molecular changes in the skin tissues were measured by immunohistochemical staining. HTD treatment decreased the atopic dermatitis (AD)-like symptoms including hemorrhage, erythema, erosion, edema, and dryness. HTD treatment suppressed the mast cell activation confirmed by reduction of $Fc{\varepsilon}RI$, substance P, and serotonin. The expression of several inflammatory mediators including nuclear factor-kappa B ($NF-{\kappa}B$) p65, inducible nitric oxide synthase (iNOS), vascular endothelial growth factors (VEGFs) was also decreased by HTD treatment. HTD treatment suppressed the allergic, inflammatory responses in the skin tissues of the NC/Nga mice by reducing mast cells and down-regulating several inflammatory mediators.

  • Synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG phosphorothioate (PS CpG-ODN) are known to decrease IgE synthesis in Th2 allergy responses. Nonetheless, the therapeutic role of PS CpG-ODN is limited due to cytotoxicity. Therefore, we developed a phosphodiester (PO) form of CpG-ODN (46O) with reduced toxicity but effective against allergies. In this study, we first compared the toxicity of 46O with CpG-ODNs containing a PS backbone (1826S). We also investigated the therapeutic efficacy and mechanism of 46O injected intravenously in a mouse model of ovalbumin (OVA)-induced atopic dermatitis (AD). To elucidate the mechanism of 46O underlying the inhibition of IgE production, IgE- and TGF-β-associated molecules were evaluated in CD40/IL-4- or LPS/IL-4-stimulated B cells. Our data showed that the treatment with 46O was associated with a lower hematological toxicity compared with 1826S. In addition, injection with 46O reduced erythema, epidermal thickness, and suppressed IgE and IL-4 synthesis in mice with OVA-induced AD. Additionally, 46O induced TGF-β production in LPS/IL-4-stimulated B cells via inhibition of Smad7, which suppressed IgE synthesis via interaction between Id2 and E2A. These findings suggest that enhanced TGF-β signaling is an effective treatment for IgE-mediated allergic conditions, and 46O may be safe and effective for treating allergic diseases such as AD and asthma.

  • To observe the effect of Demodex canis infection on the cellular immune response and hematological profile, 8 Doberman pinschers experimentally infected with D cains and 4 uninfected control dogs were sensitized with 2, 4-dinitro-chlorobenzene(DNCB) on the skin and were challenged with DNCB 14 days after the initial sensitization to elicit allergic contact dermatitis. Histological and hematological changes of these dogs were then observed. Macroscopic changes of skin challenged with DNCB in D canis-infected dogs included significantly reduced area of allergic reaction(p<0.05) than in uninfected control group. Infiltration of inflammatory cells in the D canis-infected group was also significantly reduced(p<0.05) than in the uninfected control group. These changes indicated that the cell-mediated immune response of the animals was suppressed by the infection with D canis. Total white blood cell count in dogs infected with D canis was increased when dogs were sensitized with DNCB (p<0.01). The result appeared to be caused by stress due to D canis infection, secondary bacterial infection and decreased efficacy of general body defense system. Blood eosionophils were increased in D canis-infected dogs which appreared to be caused by the allergic contact dermatitis. Blood chemistry analysis revealed that total protein and globulin were increased(p<0.05), while albumin level was decreased. This result appeared to be caused by secondary bacterial infection.

  • Natural products have received revived interest via traditional remedies or alternative medicine used for the treatment of various diseases. Zanthoxylum piperitum (ZP) has been utilized in traditional medicine for various medicinal purposes. The present study was conducted to evaluate whether ZP modulates allergic inflammation both in vivo and in vitro. We examined the pharmacological effects of ZP on 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) symptoms in mice. Additionally, in order to clarify the anti-inflammatory mechanisms of ZP, we elucidate the effect of ZP on the expression levels of inflammatory cytokines and nuclear factor-κB (NF-κB) in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). The results demonstrated that ZP attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, ZP suppressed the expression of inflammatory cytokines and activation of NF-κB in AD-like skin lesions and stimulated HMC-1. These results provide experimental evidence that ZP may be useful candidate for treating allergic inflammation including AD.

  • Objectives : The purpose of this study is to analyze the current trends of various herbal medicine research on allergic disease with dysbiosis. Methods : Electronic searches were performed using Pubmed, Research Information Sharing Service(RISS), Korean studies Information Service System(KISS), Oriental medicine Advanced Searching Integrated System(OASIS). Results : We analyzed ten studies on the effect of herbal medicine on allergic disease with dysbiosis. Eight studies were animal experimental studies, and two were randomized clinical trial(RCT) study and one-group pretest-posttest research, respectively. Among the studies, three studies were on atopic dermatitis, two on allergic rhinitis, and five on asthma. All different herbal medicines were used in the studies. Changes in gut microbiota composition were observed in nine studies except for 1 RCT study. In eight animal experimental studies, there was significant reduction in allergy-related inflammatory markers. Six studies evaluated the change of metabolites related to gut microbiota and three of them showed significant increase in short-chain fatty acids(SCFA). Conclusion : This study provides current trends of studies on herbal medicine research on allergic disease with dysbiosis. Most research is conducted using animal experiments, and this is a relatively recent trend. These studies offer basic knowledge on the correlation between herbal medicine, gut microbiota, and anti-inflammatory effects in allergic disease.

  • Objectives: Poncirus trifoliata Rafinesque has been known to have anti-allergic effects in skin diseases. However, anti-atopic dermatitis effects of P. trifoliata Rafinesque have not been studied yet in skin diseases. The present study evaluated the anti-atopic dermatitis effects of P. trifoliata Rafinesque (PTR) using external treatments on AD. Methods: AD lesions were induced by the repeated application of 2, 4-Dinitrochlorobenzene (DNCB) on the shaved back of BALB/c mice. $100{\mu}{\ell}$ of PTR extracts was applied to the AD lesions for 11 days. Histological assessments, mast cells count and serum levels of IgE were analyzed. The anti-pruritic effects of PTR were examined by the change of scratching frequency and nerve growth factor (NGF) expression. In addition, the anti-inflammatory effects of PTR were examined by the expressions of Th2/Th1 cytokines and pro-inflammatory in dorsal skin. Results: Histopathological findings showed that topical application of PTR decreased the thickness of dermal and epidermal skin compared with the DNCB group. PTR also notably decreased the mast cells count and serum IgE. The scratching behavior of mice and expression of NGF were significantly reduced. In addition, PTR group significantly suppressed the IL-4, IL-6, IFN-${\gamma}$ and TNF-${\alpha}$ cytokines compared to the DNCB group. Conclusions: These results indicated that P. trifoliata Rafinesque possess anti-pruritus and anti-atopic dermatitis properties. Therefore, P. trifoliata Rafinesque might be used for treatment of pruritus and atopic dermatitis.
