H&E examination under light microscopy (original magnification: ×100).

Notes: (A) H&E of normal lung showing thin interstitial alveolar wall and capillary vessels. Rare inflammatory cells are noted. (B) PJ lung tissue demonstrating normal lung architecture similar to that in A. (C) After acute CS exposure, note thickening of the interstitial wall, capillary congestion, and infiltration by inflammatory cells (arrows). (D) When compared to Control, CS + PJ-treated animals demonstrated remarkable reduction in inflammatory cell migration, alveolar wall thickening, and capillary congestion.

Abbreviations: CS, cigarette smoke; H&E, hematoxylin and eosin; PJ, pomegranate juice.
