Fig. 4From: Effects of airway pressure release ventilation on multi-organ injuries in severe acute respiratory distress syndrome pig modelsRepresentative light micrographs of multi-organs in different groups. A1 lung, B1 kidney, C1 intestine, D1 liver, E1 heart in the control group; A2 lung, B2 kidney, C2 intestine, D2 liver, E2 heart in the ARDS group; A3 lung, B3 kidney, C3 intestine, D3 liver, E3 heart in the LTV group; A4 lung, B4 kidney, C4 intestine, D4 liver, E4 heart in the APRV group; Histopathologic injury score in lung (A5), kidney (B5), small intestine (C5), liver (D5) and heart (E5). Black arrow in kidney = renal tubular epithelial cell edema; Red arrow in kidney = epithelial cell damage; Orange arrow in intestine = necrotic detachment of intestinal villous epithelial cells; Black arrow in liver = necrosis; Red arrow in liver = dilated liver sinuses; Yellow star in liver = fat infiltration; Green arrow = inflammatory infiltrates; Blue arrow = fibrous necrosis; small intestine: magnification 200 × ; lung, kidney, liver, heart: magnification 400 × . *p < 0.05 were calculated by Kruskal–Wallis H-test. ns = no significanceBack to article page
