Figure 7

(a) Results of immunohistochemical detection of IL-33 positive area and ST2 positive cells (×200). High magnification photo is in the black square frame (×400). Statistical results were expressed as mean ± SEMs, compared with the normal group; , , and compared with the model group. (b) Detection of the expression of IL-33 protein in mouse dorsal skin tissue by immunohistochemistry. (c) Detection of the expression of ST2 protein in mouse dorsal skin tissue by immunohistochemistry. (①): normal control group; (②): model control group; (③): low-dose QRQS group; (④): middle-dose QRQS group; (⑤): high-dose QRQS group; (⑥): cetirizine medicine group.
