Fig. 5From: Effects of the combined extracts of Herba Epimedii and Fructus Ligustrilucidi on airway remodeling in the asthmatic rats with the treatment of budesonideEffects of budesonide and the herbal extracts on mRNA expression of TGF-β/Smads. The mRNA expressions of TGF-β1 (a), TGF-β2 (b), Smad2 (c), Smad3 (d) and Smad7 (e) in lung tissue were determined by qPCR with β-actin as an internal control. In the asthmatic rats, the mRNA expressions of TGF-β1, TGF-β2, Smad2 and Smad3 were significantly higher, while that of Smad7 was significantly lower than those in the normal group. Mean ± SD, n = 7. * P < 0.05 and ** P < 0.01 compared to normal control group; # P < 0.05 and ## P < 0.01 compared to asthma model group; ▲ P < 0.05 and ▲▲ P < 0.01 compared to budesonide group; ● P < 0.05 compared to extracts groupBack to article page
