Abstract
Asthma is a state of hyperresponsiveness of airways with associated inflammation and obstruction to air track. Present report evaluated the protective effect of desoxyrhapontigenin against ovalbumin-induced rat model of asthma. In asthmatic rats, there was an increase in serum IL-4, IL-5, bronchoalveolar lavage fluid IgE, IL-4, IL-13, IL-17, transforming growth factor β1, and leucocyte count. On the contrary, there was a decrease in bronchoalveolar lavage fluid IFN-γ that was reversed by desoxyrhapontigenin but not dexomethasone. Also, the mRNA expression for NF-kBp65 and vascular endothelial growth factor increased without any change in IκBα in the asthmatic rat tissue. There was a pronounced increase in the histopathological score in asthmatic rat tissue that were diminished by desoxyrhapontigenin or dexomethasone. In conclusion, study reveals that treatment with desoxyrhapontigen may protect the bronchial asthma by modulating the inflammation and immune response in the lung tissue.
