Cytokine response of lung from orally immunized Balb/c mice. a IFN-γ (pg/ml), b IL-4 (pg/ml) c IL-2 (pg/ml), d IL-6 (pg/ml), e IL-12 (pg/ml) and f TNF-α (pg/ml) detection of spleen from the immunized mice of oral groups were performed using ELISA. Each sample was analyzed in triplicates. Results are presented as mean ± SD of the mean. Mean values of P < 0.05 = *and P < 0.01 = ** between the treatment groups and the treatment groups with the Lp control group were of significant values
