TUNEL immunopositive cells in the external plexiform layer, mitral cell layer, internal plexiform layer, and granule cell layer in the C group (A), the SI + S group at 72 h (B), and the SI + AG group at 72 h (C). Smoke inhalation increases the incidence of apoptotic cells (arrows) in the mitral cell layer (B) compared with the C group (A). The frequency of apoptotic cells in the olfactory bulb is significantly reduced in the SI + AG group at 72 h, as compared with the SI + S group (C). Scale bar =50 μm. (D) Bar graphs show increase in apoptotic cells in the SI + S group at 72 h, as compared with the C group. Apoptotic cells are significantly suppressed in numbers in the SI + AG group at 72 h, as compared with SI + S.
