  • Apoptosis signal-regulating kinase 1 (ASK1) is an upstream signaling molecule in oxidative stress-induced responses. Because oxidative stress is involved in asthma pathogenesis, ASK1 gene deficiency was investigated in animal models of allergic asthma. However, there is no study to investigate whether ASK1 inhibitors could be applied for asthma to date. Selonsertib, a potent and selective ASK1 inhibitor, was applied to BALB/c mice of an ovalbumin (OVA)-induced allergic asthma model. Selonsertib suppressed antigen-induced degranulation of RBL-2H3 mast cells in a concentration-dependent manner. The administration of selonsertib both before OVA sensitization and OVA challenge significantly reduced airway hyperresponsiveness, and suppressed eosinophil numbers and inflammatory cytokine levels in the bronchoalveolar lavage fluid. Histopathologic examination elucidated less inflammatory responses and reduced mucin-producing cells around the peribronchial regions of the lungs. Selonsertib also suppressed the IgE levels in serum and the protein levels of IL-13 in the bronchoalveolar lavage fluid. These results suggest that selonsertib may ameliorate allergic asthma by suppressing immune responses and be applicable to allergic asthma.

  • Objectives : The aim of this study was to investigate the asthma-suppressive and immuno-regulatory effect of NR-HA(Notopterygii Rhizoma Herbal-acupuncture) at Pyesu(BL13) on OVA(ovalbumin)-induced asthma in mice. Methods : C57BL/6 mice out of all the experimental sloops, except the Normal group and the NR-HA group, were sensitized and challenged with OVA. The mice in the NR-HA group and the OVA-NR-HA group were treated with NR-HA(1%) at Pyesu(BL13). The mice in the OVA-Saline group were injected with saline at Pyesu(BL13). The mice in the OVA-Needle-prick group were treated with a single prick with an injection needle at Pyesu(BL13). NR-HA, saline injection and needle prick were administered for 8 weeks, three times a week Results : in vitro 1. The populations of granulocytes, $CD3e^-/CCR3^+$cells, $CD69^+/CD3e^+$ cells, $CD4^+\;cells\;and\;CD23^+/B220^+$ cells in the OVA-induced asthmatic mouse lungs decreased significantly by NR-HAS(Notopterygii Rhizoma Herbal-acupuncture solution). 2. The lung weight and total cells in lung of the OVA-NR-HA group decreased significantly compared with those of the OVA-Control group. 3. Total leukocytes and eosinophils in BALF of the OVA-NR-HA group decreas ed significantly compared with those of the OVA-Control group. 4. The collagen accumulation in the lung sections of the OVA-NR-HA group decreased significantly compared with that of the OVA-control group. 5. The concentrations of IL-4, IL-5, IL-13, IgE in BALF and serum of the OVA-NR-HA group decreased significantly compared with those of the OVA- Control group. 6. The numbers of $Gr-1^+/CD11b^+,\;CCR3^+,\;CD3e^+, \;CD19^+,\;CD3e^+/CD69^+$ cells in the OVA-NR-HA group decreased significantly compared with those of the OVA-Control group. 7. The mRNA expressions of $TNF-{\alpha}$, IL-5, IL-4 and IL-13 in lung of the OVA-NR-HA group decreased significantly compared with those of the OVA- Control group. 8. The NR-HA group did not show my considerable difference from the Normal group. The OVA-saline group and the OVA-Needle prick group showed suppressive effects on OVA-induced asthma however they were not statistically significant.

  • The feature of asthma are airway inflammation (AI), reversible airway obstruction, and an increased sensitivity to bronchoconstricting agents, elevated airway hyperresponsiveness (AHR), excess production of Th2 cytokines, and eosinophil accumulation in the lungs. This study was performed to investigate if oral administration of $Scutellaria$ $baicalensis$ Georgi water extracts (SBG) have the antiasthmatic potential for the treatment of asthma. Asthmatic HI and AHR were induced by systemic sensitization to ovalbumin (OVA) with intratracheal instillation with 0.1 mg/mL of diesel exhaust particles (DEP) suspension once a week for 10 weeks in BALB/c mice. SBG was orally administered with the concentraion of 200 mg/kg 5 days a week for 10 weeks. Long-term SBG treatment suppressed the eosinophil infiltration into airways from blood, the asthmatic AI and AHR by attenuating the production of cytokine IL-4, IL-5 and IL-13, histamine and OVA-specific IgE. Our data suggest that SBG has inhibitory effects on AI and AHR in a mouse model of asthma, may act as a potential Th2 cytokine antagonist, and may have a therapeutic effect on allergic asthma.

  • 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.

  • 이 연구는 난백단백질의 알러지성을 없애기 위해 감마선 조사된 OVA에 대한 가열처리가 항원성(알러지성) 및 구조 변화에 미치는 영향을 조사하기위해 수행되었다. OVA 용액 (2.0 mg/mL)을 1) 가열처리구; 2) 가열 후 조사구; 3) 조사 후 가열처리구로 준비하였다. 시료를 개별적으로 가열처리하였고, 감마선 조사는 10 kGy의 흡수선량을 얻도록 조사하였다. 계란알러지가 있는 환자의 혈청과 OVA에 대해 생산된 단클론항체(M-IgG)와 다클론항체(R-IgG)를 사용하여 확립된 경합간접효소면역분석법을 사용하여 시료용액에 있는 OVA의 항원-항체 반응성을 측정하였다. 열변성된 OVA에 대한 항체반응성은 R-IgG가 6$0^{\circ}C$, M-IgG가 7$0^{\circ}C$부터, 그리고 P-IgE의 경우 8$0^{\circ}C$부터 변화하기 시작하였다. P-IgE는 8$0^{\circ}C$이상의 온도에서 가열된 OVA를 잘 인식하지 못하였다. 반면에, M-IgG와 R-IgGdmlruddn 가열처리된 OVA에 대한 P-IgE의 항원-항체 반응성에 미치는 영향은 처리 순서와는 관계없이 모든 가열온도에서 가열처리에 의한 큰 변화를 나타내지 않았다. 가열처리와 감마선 조사에서 시료용액의 혼탁도가 모두 증가하였고, 가열처리보다는 감마선 조사에 의한 혼탁도의 증가가 매우 높았다. 이 결과들은 가열처리가 감마선 조사되어 감소되어 있는 OVA의 알러지성에 큰 영향을 미치지 않는 것을 나타내었다.

  • Objectives : To investigate the immunological activities, we evaluated the combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix (AG) on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. Methods : The cellular proliferation and the production of nitric oxide were examined in a macrophage cell line, RAW 264.7 cells, in the presence of the combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix. C57BL/6 mice were immunized intraperitonially with ovalbumin/aluminium ($100{\mu}g/200{\mu}g$) on day 1, 8, and 15. The combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix (1 g/kg/day) was orally administrated for 3 weeks. On day 22, splenocyte and plasma were collected for mitogen-induced proliferation, lymphocyte subpopulation by flow cytometry and measurement of AST (Aspirate aminotransferase), ALT (Alanine aminotransferase), and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes). Results : Aconiti Lateralis Radix Preparata treatment had no influence on immune responses. The proliferation and NO production of macrophage and proliferation of splenocyte were increased as the higher ratio of Glycrrhizae Radix. The proliferation of splenocyte, lymphocyte subpopulation and production of antibody (total IgM, OVA-specific IgG and OVA-specific IgG1) were increased as the higher ratio of Glycrrhizae Radix on OVA-immunzed mice. Conclusions : These results suggest that the higher ratio of Glycyrrhizae Radix can increase immunological activities such as NO production in RAW264.7 cells, splenocyte proliferation and immunoglobulin production in OVA-immunized mice.

  • Recent study has demonstrated an increasing prevalence of food allergy in Korean children. Specific probiotic bacteria may promote potentially anti-allergenic processes through induction of Th1-type immunity and enhance the regulatory lymphocyte. This study investigated whether orally administrated probiotics could suppress allergic responses in an ovalbumin (OVA)-induced allergy mouse model. Thus, female C3H/HeJ mice were orally sensitized with OVA and cholera toxin for 4 weeks. Lactobacillus acidophilus AD031, Bifidobacterium lactis AD011, and L. acidophilus AD031 plus B. lactis AD011 were fed to mice from 2 weeks before the sensitization. The OVA-induced mice that were not treated with probiotics had significantly increased serum levels of OVA-specific IgE and IgG1, and OVA-specific IgA in feces. However, the mice treated with probiotics suppressed production of the OVA-specific IgE, IgG1, and IgA. The level of IL-4 was significantly lower, and the levels of INF-$\gamma$ and IL-10 were significantly higher in the mice treated with probiotics than that in the non-treated mice. The groups treated with probiotics had decreased levels of degranulated mast cells, eosinophil granules, and tail scabs. These results indicate that L. acidophilus AD031 and B. lactis AD011 might be useful for the prevention of allergy.

  • Objectives : We aimed to determine therapeutic effects of probiotics-fermented Magnolia denudata(MD) in the allergic rhinitis model mice. Methods : Polyphenol production, DPPH radical scavenging activity and NO inhibition of fermented MD by different bacterial strains were evaluated to select the one that is most suitable for fermentation. Thirty C57BL/6 mice were divided randomly into 5 groups as follows: normal group, ovalbumin(OVA)-treated plus water fed(CON group), OVA-treated plus unfermented MD fed(UMD group), OVA-treated plus fermented autoclaved MD fed(A-FMD group) and OVA-treated plus fermented unautoclaved MD fed(FMD group). After 9 weeks, we observed changes in the blood cell count, OVA-specific IgE level, nasal rubbing, nasal mucosal tissue and body weight. Results : Extract of MD fermented by Bifidobacterium breve(BB) for 48 hours showed the highest anti-oxidant activity and anti-inflammatory activity out of all the other bacterial strains. The number of eosinophil count in A-FMD, FMD group and platelet count in FMD group showed statistically significant decrease(p<0.05). OVA-specific IgE level decreased in all 3 experimental groups, significantly in UMD and A-FMD group. Nasal symptoms were attenuated in all 3 experimental groups, statistically significant in A-FMD and FMD group (p<0.05). Histologically, infiltration of eosinophils into the nasal mucosa decreased in all 3 experimental groups, especially marked decrease in FMD group. Conclusions : According to the above results, it is considered that probiotics-fermented Magnolia denudata has inhibitory effects on the allergic rhinitis animal models.
