BIP-V5 attenuates bleomycin-induced lung injury. (A) Kaplan–Meier curve analysis with BLM+NC or BLM+BIP. (B) Hematoxylin and eosin-stained lung tissues from mice treated with BLM+NC or BLM+BIP on day 7. Scale bars: 100 µm. (C) The pathological grades of the tissues after hematoxylin and eosin staining. The pathological grades were determined according to the following criteria: 0, no lung abnormalities; 1, presence of inflammation and fibrosis involving <25% of the lung parenchyma; 2, lesions involving 25–50% of the lung; and 3, lesions involving >50% of the lung. *P<0.05, **P<0.01. NC, negative control; BLM, bleomycin; BIP, Bax-inhibiting peptide V5.
