Values are expressed as the means ± SD or as medians (interquartile range). ^a P < 0.05 significant difference compared to DEP. AAs: anacardic acids. Ctrl: control, animals received an intranasal instillation of 10 μL saline solution and were treated orally with 100 µL of cashew nut oil (CNO). DEP: diesel exhaust particles, intranasal instillation of 50 μg DEP/10 μL of saline and treated orally with 100 µL of CNO. DA50: intranasal instillation of 50 μg DEP/10 μL of saline and treated orally with 50 mg/kg of AAs. DA150: intranasal instillation of 50 μg DEP/10 μL of saline and treated orally with 150 mg/kg of AAs. DA250: intranasal instillation of 50 μg DEP/10 μL of saline and treated orally with 250 mg/kg of AAs.
