1 Sevoflurane Attenuates Ischemia-Reperfusion Injury in a Rat Lung Transplantation Model 
Akihiro Ohsumi, MD, Katherine Marseu, MD, Peter Slinger, MD, Karen McRae, MD, Hyunhee Kim, MS, PhD, Zehong Guan, David M. Hwang, MD, Mingyao Liu, MS, MD, Shaf Keshavjee, MS, MD, Marcelo Cypel, MS, MD  The Annals of Thoracic Surgery  Volume 103, Issue 5, Pages (May 2017) DOI: /j.athoracsur Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Cytokine levels 2 hours after reperfusion. (A) Interleukin (IL)-1β in plasma, (B) IL-1β in lung tissue, (C) IL-6 in plasma, (D) IL-6 in lung tissue; (E) tumor necrosis factor (TNF)-α in plasma, (F) TNF-α in lung tissue. Data are shown as mean ± SD. The p values were calculated by one-way analysis of variance with Tukey’s multiple comparison tests. *p < (PostC = postconditioning; PreC = preconditioning; PreC + PostC = both preconditioning and postconditioning.)

3 Fig 2 Myeloperoxidase (MPO) levels in (A) plasma and (B) lung tissue. Data are shown as mean ± SD. The p values were calculated by one-way analysis of variance with Tukey’s multiple comparison tests. *p < (PostC = postconditioning; PreC = preconditioning; PreC + PostC = both preconditioning and postconditioning.)

4 Fig 3 Western blot analysis of (A) Bcl-2–associated X protein (Bax) and cytochrome c in mitochondria (loading control: voltage-dependent anion channel [VDAC]); and (B) Bax, cytochrome c, caspase-3, and cleaved caspase-3 in cytosol (loading control: β-actin); (C) caspase-3 cleavage ratio: cleaved caspase-3/caspase-3; (D) cytochrome c release: cytochrome c in cytosol/β-actin in cytosol. Data are shown as mean ± SD. The p values were calculated by Kruskal-Wallis test with Dunn’s multiple comparison tests. *p < 0.05. (PostC = postconditioning; PreC = preconditioning; PreC + PostC = both preconditioning and postconditioning.)

5 Fig 4 TUNEL staining for the (A) control, (B) PreC, (C) PostC, (D) PreC + PostC groups. Red dots are the apoptotic cells. (Magnification: ×200; scale bar = 200 μm.) (PostC = postconditioning; PreC = preconditioning; PreC + PostC = both preconditioning and postconditioning; TUNEL = terminal deoxynucleotidyl transferase-mediated deoxyuridinetriphosphate nick-end labeling.)

6 Fig 5 Hematoxylin and eosin staining for the (A) control, (B) PreC, (C) PostC, and (D) PreC + PostC groups and (E) Lung injury score. Arrowheads represent mononuclear cell infiltration. Bar indicates median value. The p values were calculated by Kruskal-Wallis test with Dunn’s multiple comparison tests. *p < 0.05. (PostC = postconditioning; PreC = preconditioning; PreC + PostC = both preconditioning and postconditioning.)
