Abstract:

We analyzed the ability of mangiferin to suppress cigarette smoke-induced chronic obstructive pulmonary disease. Control rats showed a marked decrease in the ratio of the forced expiratory volume at 0.1 s to forced vital capacity. The decreases in the peak expiratory flow and maximal mid-expiratory flow indicated airway remodeling and enlargement. The expression levels of superoxide dismutase (SOD), heme oxygenase-1 (HO-1), γ-glutamylcysteine synthetase, nuclear factor erythroid 2-related factor2, and activating transcription factor 4 were increased in the control rats. The levels of oxidative stress, malondialdehyde, and reactive oxygen species peaked after 24 weeks, whereas the SOD and HO-1 levels and the total antioxidant capacity were reduced in control rats. Mangiferin restored thelevels of reactive oxygen species, malondialdehyde, SOD, HO-1, and T-AOC to near normal. Increased numbers of infiltrating inflammatory cells were observed in control rats but were significantly reduced by mangiferin. In addition, edema and airway inflammation were reduced by mangiferin.
