Figure 7From: Combustion smoke-induced inflammation in the olfactory bulb of adult rats Immunoexpression of nNOS (red) and NeuN (green) in the olfactory bulb of the C group (A-C), the SI + S group at 24 and 72 h (D-I), and the SI + AG group at 72 h (J-L). In the normal bulb, nNOS expression is absent (A-C); however, in the SI + S group, it is induced in some neurons at different time points (24 and 72 h, D-I); the incidence of labeled cells is higher at 24 h (E). Aminoguanidine administration did not obviously alter the immunofluorescence at 72 h (J-L). Scale bar =20.0 μm.Back to article page
