"IL-5 (a) and IFN-γ (b) concentration in the pleural exudates. Mice were sensitized with OVA and the allergic pleurisy reaction was elicited after 14 days as described in ""Materials and methods"". BLF (100 μg/dose) was given buccally to mice 24 and 3 h before OVA challenge. The pleural exudates were harvested 24 h later and the cytokine concentrations were determined by ELISA. The results were shown in picograms/ml of IL-5 or IFN-γ as mean values from 5 mice ± SE. Statistics: a BG versus control, P = 0.0001; control versus BLF, P = 0.0003 (ANOVA); b BG versus control NS (P = 0.6345); control versus BLF NS (P = 0.8510) (ANOVA). NS not significant"
