NO₂ (a), NO₃ (b) and MDA (c) concentration in bronchoalveolar lavage fluid (BALF) of control (C) asthma group (A), asthmatic rats treated with dexamethasone (A+D) and asthmatic rats treated with P. oleracea (PO 1, 2 and 4 mg/mL) (n = 8 in each group). Data are expressed as mean ± SEM values. ** p < 0.01 and *** p < 0.001 show significant differences compared to group C. +++ p < 0.001 shows significant differences compared to group A. # p < 0.05 and ### p < 0.001 show significant differences compared to group A+D. xx p < 0.01 and xxx p < 0.001 show significant differences among the three concentrations of P. oleracea. Statistical analyses were performed using ANOVA with Tukey-Kramer’s post-test
