Effect of the CTCM on the release of histamine and IL-4 in P815 mast cells. Compound 48/80 was used to activate the P815 mast cells as a positive control, and cromolyn sodium was used to stabilize the mast cells as a negative control. The release of (A) histamine and (B) IL-4 in the culture medium with saline, “Compound 48/80 (C48/80) + CTCM (100 μg/ml)” or “Compound 48/80 + cromolyn sodium” were examined (one-way ANOVA with a Duncan post-hoc test **P <0.01; compared to Compound 48/80 treatment).
