(a) The expression of IL-33 in the supernatant of mast cells stimulated by Art. for 12 h; (b) the expression of IL-33 in the supernatant of mast cells treated by ZnSO₄ combined with Art. for 12 h. ^∗ and ^∗∗. Group A: blank control group, group B: ZnSO₄ 50 μmol/L + Art. 0.01 μg/ml, group C: ZnSO₄ 100 μmol/L + Art. 0.01 μg/ml, group D: ZnSO₄ 200 μmol/L + Art. 0.01 μg/ml, group E: ZnSO₄ 100 μmol/L + Art. 0.1 μg/ml, and group F: ZnSO₄ 100 μmol/L + Art. 0.001 μg/ml.
