Effects of SB203580 on pulmonary capillary injury of severe acute pancreatitis rats. A: Evans blue extravasation in lung tissues; B: Bronchoalveolar protein concentration; C: Representative electron microscope photomicrographs of pulmonary microvascular endothelial cells in lung tissues; Sham group: Magnification 1500 × and 4000 ×, respectively; Severe acute pancreatitis (SAP) group: Magnification 1500 × and 5000 ×, respectively; SAP + SB10 group: Magnification 1500 × and 5000 ×, respectively; White arrows: Dense endothelial cell–cell junctions; White arrowheads: Low electron density clouds with an irregular thickness indicating basal membrane edema; Yellow arrows: Dissolution, rupture and debris of capillary endothelial; Orange star: Red blood cell. Data were expressed as mean ± SE; aP < 0.05 vs sham group; bP < 0.05 vs SAP group; cP < 0.05 vs SAP + SB2.5 group. SAP: Severe acute pancreatitis.
