Figure 3From: Characterization of the innate immune response to chronic aspiration in a novel rodent modelFibrosis following gastric fluid aspiration. The fibrosis grade was evaluated as described in the Methods. The mean peribronchiolar fibrosis grade was significantly higher in left (treated) lung specimens compared to right (untreated) lung specimens after 4, 8, 12, and 16 weeks of gastric fluid aspiration. **p < 0.01, ***p < 0.001 based on two-tailed Student's t test.Back to article page
