    Abstract:
    Many plant species containing flavonoids have been widely used in traditional Chinese medicine. Naringin, a well-known flavanone glycoside of citrus fruits, possesses antioxidant, anti-inflammatory, anti-apoptotic, anti-ulcer, anti-osteoporosis, and anti-carcinogenic properties. The aim of the study was to investigate the anti-asthmatic effects of naringin and the possible mechanisms. Asthma model was established by ovalbumin. A total of 50 mice were randomly assigned to five experimental groups: control, model, and dexamethasone (2 mg/kg, orally) and naringin (5 mg/kg, 10 mg/kg, orally). Airway resistance (Raw) were measured, histological studies were evaluated by the hematoxylin and eosin (HE) staining, OVA-specific serum and BALF IgE levels and Th1/Th2 cytokines were evaluated by enzyme-linked immunosorbent assay (ELISA), and Th1/Th2 cells was evaluated by flow cytometry (FCM). T-bet and GABA3 in the lung were evaluated by Western blot. Our study demonstrated that naringin inhibited OVA-induced increases in Raw and eosinophil count; OVA-induced effects on interleukin (IL)-4 and INF-gamma levels were blunted with naringin administration. Histological studies demonstrated that naringin substantially inhibited OVA-induced eosinophilia in lung tissue and airway tissue. Flow cytometry studies demonstrated that naringin substantially inhibited Th2 cells and enhanced Th1 cells. Naringin substantially inhibited GABA3 and increased T-bet. These findings suggest that naringin may effectively ameliorate the progression of asthma and could be used as a therapy for patients with allergic asthma.
