Histomorphological features of the olfactory rosette of Atlantic salmon intermittently exposed to PAA. A The thickness of the olfactory epithelium and lamina propia. Values presented are mean ± SE of 8 individual fish per sampling point. Different letters denote significant difference at P < 0.05. Samples were collected before and 22 and 45 days after intermittent oxidant exposure. B Representative pictographs of the olfactory rosette stained with AP/PAS showing a considerable increase in the mucous cells (arrow; stained dark blue) at the tip of the olfactory lamella at day 0 (B) compared with at day 45 (C). NC = nasal cavity; LP = lamina propia; OE = olfactory epithelium; M = mucus. Scale bar = 100 μm
