Effects of carvone enantiomers on leukocyte recruitment in allergic airway inflammation. (A) Total leukocytes, (B) Eosinophils, (C) Mononuclear cells and (D) Neutrophils per bronchoalveolar lavage (BAL) of BALB/c mice orally pre-treated with R-carvone (10 mg/Kg), S-carvone (10 mg/Kg) or dexamethasone (1 mg/Kg), counted under light microscopy 24 h after the last ovalbumin (OVA)-challenge. Results are expressed as means ± SEM and are representative of two independent experiments performed with 6–8 animals per group. + significant difference (p < 0.05) from the unchallenged group; * (p < 0.05), ** (p < 0.01) and *** (p < 0.001) express significant difference from the untreated OVA-challenged group. Statistical significance was determined with one-way ANOVA and post hoc Tukey test.
