Fig. 3From: Artesunate ameliorates cigarette smoke-induced airway remodelling via PPAR-γ/TGF-β1/Smad2/3 signalling pathwayArtesunate restored lung function declining and airway hyperresponsiveness caused by CS. After CS exposure for 12 weeks, the lung function of rats was assessed by using a PowerLab 8sp Life Analysis System, including a peak inspiratory flow (PIF), b peak expiratory flow (PEF), c inspiratory pressure (IP), d airway pressure maximum rising slope (IP-slope). e isometric force. Data were expressed as mean ± SEM, n = 6, ##P < 0.01 compared to control group using unpaired t-test; *P < 0.05, **P < 0.01and ns means no significant difference compared to CS group using one-way ANOVA with Dunnett test for selected pairs.
