Objectives : In this study, we investigated the effect of Saposhnikoviae Radix on allergic responses in ovalbumin(OVA)-induced Allergic rhinitis(AR) mice. Methods : BALB/c mice were orally administrated with Saposhnikoviae Radix water extract (SRW, 50 mg/kg) or anti-histamine drug, Ketotifen (10 mg/kg) as a reference drug, followed by sensitization and challenge of OVA. Mice were measured clinical symptoms and the serum levels of histamine, IgE, IL-4, and IFN-${\gamma}$, and observed histopathological changes of nasal mucosa H&E staining. Results : SRW significantly decreased rubs and the serum levels of histamine, IgE, and IL-4, and then increased the serum levels of IFN-${\gamma}$ in OVA-induced AR mice, and inhibited histopathological changes of nasal mucosa with inflammation and the eosinophils infilteration. Conclusions : These data suggest that SRW has anti-allergic effect through the inhibitory property of Saposhnikoviae Radix against allergic responses in allergic rhinitis.

Objectives : In this study, we investigated the effect of Cassia obtusifolia Linne (Cassiae Semen; CS) extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : CR was extracted with 70% ethanol. For in vitro study, HMC-1, human mast cells were treated with CS extract at 0.2 and $0.5mg/m{\ell}$ for 1 h, and then stimulated with compound (C) 48/80 for 30 min. Primary spleenocytes were isolated from the spleen of mice, treated with CS extract for 1 h, and then stimulated with ConA for 24 h. For in vivo study, mice were sensitized at day 0, 7 and 14 with 0.2% OVA and then airway challenged using neublizer at day 21, 23, 25, and 27 to induced allergic asthma. CS extract at doses of 100 and 300 mg/kg body weight was orally administered during OVA challenge once per a day. The levels of allergic mediators such as histamine, OVA-specific IgE, IL-4, and $IFN-{\gamma}$ were measured in the sera of mice or culture supernatants by EIA and ELISA, respectively. The expression of IL-4 and $IFN-{\gamma}$ gene was determined by RT-PCR. The histopathological change of lung tissues was observed with hematoxylin and eosin (H&E) and Periodic acid Schiff (PAS) staining. Results : The treatment of CS extract in HMC-1 cells significantly inhibited C48/80-induced degranulation, and histamine release. The treatment of CS extract in spleenocytes suppressed the expression of IL-4 and $IFN-{\gamma}$ mRNA. The administration of CS extract in OVA-induced asthmatic mice significantly decreased the levels of OVA-specific IgE, and IL-4 in a dose-dependent manner with OVA-control group. In addition, CS extract inhibited the infiltration of inflammatory cells and bronchiolar damage with epithelial thickening in lung tissues of OVA-induced asthma mice, and also mucin accumulation. Conclusions : These results indicate that CS extract prevents asthmatic damage through regulating the allergic immune response.

Objective : Allergic rhinitis (AR) is an allergic inflammation of the nasal airways. Socheongryong-Tang traditionally has been used in Korea for treatment of allergy diseases. In the present study, we investigated whether SCRT suppresses the progression of AR in vivo and in vitro. Method : In this study, we investigated the effect of oral administration of SCRT on the Ovalbumin(OVA)-induced allergic rhinitis mouse models. Additionally, to find a possible explanation for the anti-inflammation effects of SCRT, we evaluated the inflammatory cytokine levels in LPS-stimulated mouse inflammation cell (RAW264.7) and mouse splenocyte. Results : The finding of this study demonstrated that SCRT reduced mast cells and inflammation cells infiltration in OVA-induced nasal cavity. Additionally, SCRT inhibited the production of inflammatory cytokines in splenocyte. However SCRT don't inhibited the production of inflammatory cytokines in RAW264.7 cells. Conclusion : Taken together, our results showed that oral administration of SCRT beneficial effects in allergic rhinitis, suggesting that SCRT might be a useful candidate for the treatment of allergic rhinitis.

Objectives : The root of Codonopsis pilosula (Fr.) Nannf. (Codonopsis Pilosulae Radix) has been traditionally used as a oriental medicine with an anti-thrombotic, antidiabetic, anticancer, and anti-gastric ulcer effects and immunological adjuvant. In this study, we investigated the effect of 70% ethanol extract of Codonopsis Pilosulae Radix (CPR-E) on ovalbumin (OVA)-induced allergic responses in mice. Methods : Mice were sensitized (1, 8, and 15 days) with OVA and airway challenged(22, 24, 26, 28, and 30 days) to induced allergic responses. CPR-E extract at doses of 50 and 100 mg/kg/body weight was orally administered from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and Th1/Th2 cytokines such as IFN-${\gamma}$ and IL-4 were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : CPR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-${\gamma}$. Based on H&E staining, CPR-E extract inhibited the infiltration of inflammatory cells into lung tissues with histological changes. Conclusions : These results indicate that CPR-E extract has anti-inflammatory and anti-allergic responses through regulating the cytokine balance, suggesting that the extract may be useful for the treatment of allergic inflammatory diseases such as bronchial asthma and allergic rhinitis.

Objectives : Allergy has been described as an inflammatory with hypersensitivity resulting from seasonal or perennial responses to specific allergens. The root of Platycodon grandiflorum (Jacq.) A. DC.(Platycodi Radix; Campanulaceae) has been traditionally used to treat chronic diseases such as bronchitis, asthma, pulmonary tuberculosis, inflammation and hyperlipidemia. In this study, we examined the effect of 70% ethanol extract of Platycodi Radix (PR-E) on ovalbumin (OVA)-induced airway inflammation in mice. Methods : Mice were sensitized and challenged by OVA inhalation to induced chronic airway inflammation, and then were intragastrically administered PR-E extract at doses of 50 and 200 mg/kg/day from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and cytokines such as IL-4 and IFN-${\gamma}$ were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : PR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and Th2 cytokine, IL-4 compared with those in the OVA-induced group. PE-E extract significantly increased the serum level of Th1 cytokine, IFN-${\gamma}$. Based on lung histopathological studies, inflammatory cell infiltration and mucus hypersecretion were inhibited by PE-E extract administration compared to that in the OVA-induced group. Conclusions : These findings indicate that PE-E extract may be useful as an adjuvant therapy for the treatment of bronchial asthma.

Objectives In the past, studies have been shown that Forsythiae Fructus (FF), Ulmi Cortex (UC) and JwaGwiEum (JGE) are effective in treating allergic reactions. However, no report shows the difference in effects of FF, UC and JGE in allergic rhinitis (AR). Therefore, the purpose of this study was to differentiate the effects of FF, UC and JGE in AR induced by ovalbumin (OVA) in mice. Methods From this experiment, the effects of FF, UC and JGE were several - changes in body weight, hematologic changes such as WBC, RBC, Hb and PLT counts, immunological changes such as levels of histamine, IgE, IL-4 and expressions of iNOS & COX-2 mRNA. Moreover, histological change of nasal mucosa was also investigated. Results FF administration group and JGE administration group significantly inhibited level of IgE compared to the control group. Also, FF administration group, UC administration group and JGE administration group inhibited IL-4 and expressions of iNOS & COX-2 mRNA. In histological assessment, FF administration group, UC administration group and JGE administration group showed reduced amount of subepithelial edema, desquamated mucosa and hyperplasia of basement membrane from OVA.

Objectives : In this study, we investigated the effects of Agastachis Herba water (AH-W) extract on compound 48/80-induced mast cell degranulation and histamine release in human mast cells and also anti-asthmatic effect of AH-W extract on ovalbumin (OVA)-induced asthma in mice. Methods : Human mast cells, HMC-1 were treated with AH-W extract in the presence or absence of compound 48/80 (C48/80). Mast cell degranulation was observed by microscope, and the histamine release was measured in culture medium by ELISA. For preparation of asthmatic in vivo model, mice were sensitized (0, 7, and 14 days) with OVA and airway challenged (21, 23, 25, 27, and 29 days). AH-W extract at doses of 100 and 300 mg/kg/body weight was orally administered during OVA challenge once per a day. The levels of immunoglobulin (Ig) E, and Th1/Th2 cytokines, IFN-$\gamma$ and IL-4 were measured in the sera of mice by ELISA. The histopathological change of lung tissues was observed by hematoxylin and eosin (H&E) and Periodic Acid Schiff (PAS) staining. Results : The treatment of AH-W extract significantly decreased the mast cell degranulation and histamine release in C48/80-stimulated HMC-1 cells. In addition, The administration of AH-W extract at does of 100 and 300 mg/kg significantly decreased the serum levels of OVA-specific IgE compared with those of OVA control group. In H&E and PAS staining, AH-W extract inhibited OVA-induced airway inflammation, and inflammatory cells infiltration, and also histopathological damages on lung tissues such as bronchiole epithelial desquamation, goblet cells hyperplasia, and mucin releasing. Conclusions : These results indicate that AH-W extract may improve asthmatic symptoms through mast cell stabilization and inhibiting the lung inflammation in bronchial asthma.
