a Dietary intake changes during the 4 weeks of the experimental period. b Representative H&E-stained lung tissues from mice in the control, emphysema, and emphysema with SCFA supplementation groups (magnification: 100×). c The MLI of lung tissues from each group. d, e The levels of the cytokines IL-6 and IFN-γ in the BALF (d) and serum (e) measured using ELISA. f The relative mRNA levels of TNF-α, IFN-γ, IL-8, IL-18, IRF-5, TGF-β, MMP-9, MMP-12, and Cathepsin S in the lung tissue (n = 5 mice per group; n = 4 control mice for IL-6 analysis in BALF). Values are expressed as the mean ± SE. *P < 0.05 and **P < 0.01. CTL control, E emphysema.
