(A) IL-1β concentrations in MEEs. (B) TNF-α concentrations in MEEs. The IL-1β levels in MEEs of P6+CT-immunized mice was slightly lower than those in MEEs of control mice (day 3, P = 0.732; day 7, P = 0.189). The TNF-α concentrations in MEEs of P6+CT-immunized mice were significantly less than those in MEEs of control mice (P = 0.041) and CT-immunized mice (P = 0.027) on postchallenge day 3. On postchallenge day 7, statistical significance was not demonstrated between P6+CT-immunized and control mice (P = 0.089). The TNF-α and IL-1β concentrations in MEEs of CT-immunized mice were not different from those in MEEs of control mice throughout the experiment (P > 0.05). These results are expressed as the mean ± SE and were obtained from a total of three experiments with 14 mice per group.
