Immunoexpression of AQP4 (red) and GFAP (green) in the olfactory bulb of the C group (A-C) and the SI + S group at 24 and 72 h (D-I). In the normal olfactory tissue, AQP4 expression is localized in the astrocytic foot processes (arrows) and blood vessels (arrowheads) (A-C). In the SI + S group, AQP4 expression is increased at different time points (24 and 72 h, D-I), being more conspicuous at 24 h (E). Intense AQP4 immunoreactivity is localized in GFAP-labeled astrocyte processes and end-feet and blood vessels, which are well delineated (C,F,I). Aminoguanidine administration did not suppress the immunofluorescence at 72 h (image not shown). Scale bar =20.0 μm.
