Angelicin, a furocoumarin found in Psoralea corylifolia L. fruit, has been reported to have anti-inflammatory activity. The purpose of this study was to determine the protective effects of angelicin on allergic asthma induced by ovalbumin (OVA) in mice. Mice were sensitized to OVA (on days 0 and 14) and challenged with OVA three times (on days 21 to 23). Angelicin (2.5, 5, 10 mg/kg) was given intraperitoneally 1 h before OVA treatment after the initial OVA sensitization. The production of IL-4, IL-5, and IL-13 in BALF and IgE in the serum were measured by ELISA. Lung histological changes were detected by using hematoxylin and eosin (H&E) stain. The results showed that angelicin significantly inhibited inflammatory cells infiltration into the lungs. Histological studies showed that angelicin significantly attenuated OVA-induced lung injury. Meanwhile, treatment of angelicin dose-dependently inhibited OVA-induced the production of IL-4, IL-5, and IL-13 in BALF and IgE in the serum. Furthermore, angelicin was found to inhibit airway hyperresponsiveness and NF-kB activation. In conclusion, our results suggested that angelicin inhibited allergic airway inflammation and hyperresponsiveness by inhibiting NF-kB activation.

D001249 Asthma A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL). Asthma, Bronchial,Bronchial Asthma,Asthmas
D016207 Cytokines Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. Cytokine
