Effects of curcumin treatment on histopathological changes in BaP -induced lung tissue: Control group (a); BaP -induced group (b–f); (b) mild bronchitis, scant chronic inflammatory cell infiltrate in the wall of the respiratory bronchiole. Mild intra-alveolar haemorrhage as well, (c) moderate interstitial inflammatory cell infiltrate. Acute lung injury as intra-alveolar haemorrhage is also noted and acute on chronic changes; (d) moderate to marked mixed interstitial inflammatory cell infiltrate, suggestive of interstitial pneumonitis. Interstitial fibrosis is also appreciated; (e) interstitial chronic inflammatory cell infiltrate, suggestive of interstitial pneumonitis. Type 2 pneumocytes are also prominent; (f) hyper inflated alveolar spaces and mild septal inflammatory cell infiltrate. Scale bar = 50 μm.
