Abstract
BACKGROUND: This study was conducted to evaluate the effects of astragaloside IV and budesonide on bronchitis in rats and to explore the mechanism involved.
MATERIAL AND METHODS: Eighty Sprague-Dawley (SD) rats were randomly divided into 5 groups, including a Bronchitis model group (BM), a Budesonide group (BG), an Astragaloside IV group (AG), an Astragaloside IV combined with Budesonide group (CG), and a blank control group (BC). Lung tissue was stained with hematoxylin and eosin (H&E). The activity of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) were detected by enzyme-linked immunosorbent assay (ELISA). The nuclear factor erythroid 2 [NF-E2]-related factor 2 (Nrf2), Kelch-like erythroid cell-derived protein with CNC homology [ECH]-associated protein 1 (Keap1), BTB and CNC homology 1 (Bach1), B-cell lymphoma-2(Bcl-2), and BCl-2-associated X protein (Bax) mRNA and protein were examined by RT-PCR and Western blot, respectively.
RESULTS: Compared with the Bronchitis model group, the lung tissue lesions in the Budesonide group, Astragaloside IV group, and Astragaloside IV combined with Budesonide group were effectively ameliorated and the airway resistance was significantly decreased. The activities of SOD, GSH-Px, and CAT were increased after treatment with drugs, while the content of MDA was decreased. The levels of Nrf2, Keap1, and Bcl-2 proteins were increased and the levels of Bach1 and Bax were decreased after treatment with Budesonide and Astragaloside IV.
CONCLUSIONS: Astragaloside IV combined with budesonide can ameliorate the lesions caused by bronchitis in rats through activating the Nrf2/Keap1 pathway, which plays a protective role on anti-oxidative stress injury.
