Figure 1From: Comparison between conventional and "clinical" assessment of experimental lung fibrosisRepresentative lung histology. (A) naïve lungs, (B) day 14, (C) day 21, (D) day 35, (E) day 56 and (F) day 225 after intratracheal AdTGF-β1 administration (40×). (G) Fibrotic index (Ashcroft). (G) Hydroxyproline content per mg dry lung. Group comparison was performed using one way ANOVA with Dunnett's multiple comparison test. All values are given as mean, SE, n = 4–6 in each group, * p < 0.05, ** p < 0.01, *** p < 0.001 vs. naïve.Back to article page
