Figure 4.

BALF levels of INF-γ (a) and INF-γ/IL-4 ratio (b) (mean±SEM) in control rats (C), sensitized animals (S), S treated with dexamethasone (S+D) and two concentrations of alpha linolenic acid (S+ALA), (n=4 for ALA and n=6 for other groups)

Statistical differences between groups S, S+D and S+ALA versus group C; *** P<0.001

Statistical differences between groups S+D and S+ALA versus group S; +++ P<0.001

Statistical differences between groups S+ALA versus group S+D; ## P<0.01, ### P<0.001

Statistical differences between groups S+ALA 0.2 mg/ml versus S+ALA 0.4 mg/ml; × P<0.05, ××× P<0.001. The statistical comparisons were made using one way analysis of variance (ANOVA) with Tukey-Kramer’s post-test
