Effect of Cymbopogon citratus treatment on expression of NF-κB p65 in the lung tissue of mice sensitized with Bt antigen. Sections were stained by immunohistochemistry (magnification × 400). Lung sections from A/J mice sensitized and treated with saline a, sensitized with Blomia tropicalis (100 μg/animal) and 4 mg/mL of [AL(OH)₃] and treated with saline b, sensitized with Blomia tropicalis (100 μg/animal) and 4 mg/mL of [AL(OH)₃] and treated with Cymbopogon citratus hexane extract (CyH) at 60 mg/kg c, 120 mg/kg d, 180 mg/kg e or 3 mg/kg dexamethasone f. g presents the quantification of NF-κB p65 expression, Scale bar, 100 μm
