Comparison of TUNEL, hematoxylin and eosin (H&E), and myeloperoxidase (MPO) staining in control and experimental NHPs. a-b: TUNEL staining in control (a) and experimental NHPs (b) demonstrated a significant difference in pneumocyte apoptosis in the experimental, polytrauma group (g). c-d: H&E staining of control (c) and experimental NHPs (d) showing increased airspace edema and alveolar wall thickening in the experimental group. e-f: Comparison of MPO activity in control (e) versus experimental NHPs (f) revealed a significant difference accumulation of MPO+ activated neutrophils in the polytrauma arm (h)
