We investigated the effect of Perilla frutescens (PF) ethanol extract powder (PF-E30) on the local allergic reaction activated by anti-DNP IgE and the mast cell-mediated immediate-type allergic reactions induced by compound 48/80 in a mouse model. One gram of PF powder extracted with 30% ethanol at $80^{\circ}C$ contained 12.3 mg of rosmarinic acid. Oral administration of PF-E30 (0.1 to 0.5 mg/kg body weight) significantly reduced plasma histamine levels and inhibited histamine release from peritoneal mast cells in mice activated by compound 48/80 or anti-DNP IgE. Moreover PF-E30 dose-dependently inhibited the production of antigen-induced IgE. These results indicate that the PF ethanol extract inhibits mast cell-mediated immediate-type allergic reactions in vivo and in vitro.

A 29-year-old male patient was admitted due to his general weakness and poor oral intake for several months. He was diagnosed as having Crohn disease 16 years ago and total colectomy was performed 10 years ago. On the 3rd day after admission, gross hematuria and sudden hemoptysis combined with diffuse infiltration were noted on chest X-ray. His symptoms and the diffusely increased lung opacities improved with administering high-dose steroid therapy. Later, anti-GBM antibody was found to be positive on the laboratory findings. We report here on a rare case of Goodpsture syndrome combined with prolonged Crohn disease along with a review of literature.

Allergic diseases have increased over the past several decade worldwide including developing countries. Allergic inflammatory responses are caused by Th (T helper)2 immune responses, triggered by allergen ingestion by antigen presenting cells such as dendritic cells (DCs). Intestinal microorganisms control the metabolism and physiological functions of the host, contribute to early immune system maturation during the early life, and homeostasis and epithelial integrity during life. Bifidobacteria have strain-specific immunostimulatory properties in the Th1/Th2 balance, inhibit TSLP (thymic stromal lymphopoietin) and IgE expression, and promote Flg (Filaggrin) and FoxP3 (Treg) expression to alleviate allergies. In addition, unmethylated CpG motif ODN (oligodeoxynucleotides) is recognized by TLR (toll-like receptors)9 of B cells and plasmacytoid dendritic cells (pDCs) to induce innate and adaptive immune responses, while the butyrate produced by Clostridium butyricum activates the GPR (G-protein coupled receptors)109a signaling pathway to induce the expression of anti-inflammatory gene of pDCs, and directly stimulates the proliferation of thymically derived regulatory T (tTreg) cells through the activation of GPR43 or inhibits the activity of HADC (histone deacetylase) to differentiate naive $CD4^+$ T cells into pTreg cells through the histone H3 acetylation of Foxp3 gene intronic enhancer.

Background and Objective : Atractylodes japonica (AJ) is a commonly-used herbal medicine in Asian countries such as Korea, China and Japan. The present study was designated to evaluate the direct effects of AJ on helper T cell activities and on Th1/Th2 lineage development in vitro. Materials and Methods : Spleen cells from 8-week BALB/c mice were cultured in CR extracts containing medium without activation for 24 hours and with activation for 48 hours. CD4+ T cells were isolated and analyzed for mRNA expression levels of INF-$\gamma$, IL-4, T-bet and GATA-3 by RT-PCR and secretion cytokines levels of INF-$\gamma$, IL-2, IL-4, IL-5 and IL-10 by ELISA. Results : The results demonstrated that AJ had no mitogenic effects on unstimulated CD4+ T cells, but augmented CD4+T-cell proliferation upon activation with anti-CD3/anti-CD28 antibodies in a dose-dependent manner. AJ treatment significantly increased CD4+ T cell population and IFN-$\gamma$ expression was significantly enhanced, while IL-4 expression significantly decreased. In addition, in vitro Th1/Th2 polarization experiments revealed that AJ enhanced IFN-$\gamma$ secretion in Th1 cells, but reduced the IL-4 in Th2 cells in dose-dependent manner. Conclusion : These results suggest that AJ treatment could be a desirable alternative therapy for the prevention or correction of Th2 dominant pathological disorders, such as allergy and asthma.

Objectives : Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous inflammtion of the skin. The chestnut inner shell extracts (CI) has been used as a cosmetic material for a long time in Korea. However, the precise anti-allergy effects of CI have yet to be clearly elucidated. In this study, we attempted to evaluate the effect of CI on mast cell-mediated allergy inflammation. Methods : To find the anti-allergy and inflammatory effect of CI, we investigated the inhibitory effect of CI on the production of inflammatory mediators using by enzyme-linked immunosorbent assay in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore (A23187) stimulated-human mast cell (HMC-1). Results : In this study, we found that CI did not show cytotoxic effect at up to 10 ug/ml on HMC-1. CI inhibited the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and IL-8 in stimulated HMC-1. Maximal rate of TNF-${\alpha}$, IL-6 and IL-8 inhibition by CI (10 ug/ml) were about 47.6%, 44.1% and 22.5% respectively. In addition, we showed that Fr.3 isolated from n-Butyl alcohol layer of CI attenuated the production of TNF-${\alpha}$, IL-6 and IL-8 in HMC-1. Conclusion : Taken together, the findings of this study provide us with a novel insight action of CI as a potential molecule for use in the treatment of allergic inflammation diseases.

Egg allergy has been raised as the most prevalent food hypersensitivity in children. Ovalbumin (OVA), which is one of the major egg allergens, is the major protein in egg white. Isoliquiritigenin (ILG) is an active component present in licorice and has been used to treat many chronic diseases for many years. In this study, we present biochemical evidence that ILG inhibits OVA-induced nuclear factor-${\kappa}B$ (NF-${\kappa}B$) activation. ILG also inhibits OVA-induced cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expression. These data suggest that ILG has anti-allergy effects.

Asthma is a chronic airway inflammatory disease characterized by reversible airway obstruction and airway hyperreactivity to various environmental stimuli, leading to recurrent cough, dyspnea, and wheezing episodes. Regarding inflammatory mechanisms, type 2/eosinophilic inflammation along with activated mast cells is the major one; however, diverse mechanisms, including structural cells-derived and non-type 2/neutrophilic inflammations are involved, presenting heterogenous phenotypes. Although most asthmatic patients could be properly controlled by the guided treatment, patients with severe asthma (SA; classified as a treatment-refractory group) suffer from uncontrolled symptoms with frequent asthma exacerbations even on regular anti-inflammatory medications, raising needs for additional controllers, including biologics that target specific molecules found in asthmatic airway, and achieving the precision medicine for asthma. This review summarizes the immunologic basis of airway inflammatory mechanisms and current biologics for SA in order to address unmet needs for future targets.

Aspirin-intolerant asthma (AIA) is characterized by severe asthmatic attack after ingestion of aspirin and/or non-steroidal anti-inflammatory drugs. In this study, we investigated the relationship between Prostaglandin E2 receptor (PTGER) gene family polymorphisms and AIA in 243 AIA patients and 919 aspirin-tolerant asthma (ATA) controls of Korean ethnicity in two separate study cohorts. After genotyping 120 SNPs of the PTGER gene family for the $1^{st}$ cohort study, four SNPs in PTGER1, ten in PTGER3, six in PTGER3, and a haplotype of PTGER2 showed association signals with decreased or increased risk of AIA. Among the positively associated SNPs, one in PTGER1 and four in PTGER3 were analyzed in the $2^{nd}$ cohort study. The results show that rs7543182 and rs959 in PTGER3 retained their effect, although no statistical significance was retained in the $2^{nd}$ cohort study. Our findings provide further evidence that polymorphisms in PTGER3 might play a significant role in aspirin hypersensitivity among Korean asthmatics.

Cimicifuga racemosa (Black cohosh) has been used as therapeutics for pain and inflammation in Korean folk medicine. The potential effects of cimicifuga racemosa extract on mast cell dependent allergy reaction, however, have not been well elucidated yet. In the present study, we investigated the effect of cimicifuga racemosa extract on the allergy reaction using mast cell dependent in vivo and in vitro models. The oral administration of cimicifuga racemosa extract showed inhibitory potential on the compound 48/80 induced active systemic anaphylactic shock. cimicifuga racemosa extract also significantly inhibited the anti DNP IgE induced passive cutaneous anaphylaxis (PCA) reaction and acetic acid induced vascular permeability. In addition, cimicifuga racemosa extract inhibited the beta hexosaminidase release and TNF alpha and IL 4 mRNA induction by DNP HSA in rat leukemia mast cells, RBL 2H3. but cimicifuga racemosa extract didn't affected to RBL 2H3 cell viability. These results demonstrated that cimicifuga racemosa extract has an anti allergic potential and it may be due to the inhibition of histamine release and cytokine gene expression in the mast cells.
