Lung Injury Scoring. Representative slides of H&E staining from the left lower lobe of lungs from AP lambs (A), early MV lambs (B), and late MV lambs (C) are shown (10x magnification). Lungs from AP lambs were better inflated and contained less hemorrhage than early MV lambs. D) Lung slides were scored 0-4 for injury by a pathologist blinded to experimental group in multiple categories. Significant differences were seen between lungs from AP lambs and early MV lambs in alveolar and interstitial hemorrhage as well as necrosis. E) Total injury scores were significantly lower in AP lungs than early MV lungs, and also appeared lower, though not significantly, than late MV lungs. (Mean ± SD; *p<0.01, **p<0.001, ANOVA, Tukey)
