Representative images of lung histology in the rats of four groups (HE staining, ×100). A. Control group, we observed normal alveolar structures and no hemorrhage or effusion in alveolar spaces. B. LPS group, we observed abnormal alveolar structures, and hemorrhage and effusion in alveolar spaces. We also observed the infiltration of inflammatory cells. C. LPS + Ab group, D. LPS + bortezomib group, we observed much less abnormal alveolar structures, hemorrhage and effusion than in LPS group.
