Values of total IgE and OVA-specific IgG 1 , IgG 2a , and IgE. The 4 groups of mice were intratracheally administered vehicle, CSBG, OVA, or a combination of CSBG + OVA for 4 wk. Serum samples were retrieved 24 h after the last intratracheal instillation. Total IgE and OVA-specific IgG1, IgG2a, and IgE were analyzed using ELISA. The results are expressed as the mean ± SE (n = 13 in each group). * P < 0.05 and ** P < 0.01 vs. vehicle; # P < 0.01 vs. OVA; $ P < 0.01 vs. CSBG.
