Effects of PLG on immune cell infiltration in DNCB-induced mice. a, b Infiltration of eosinophils and mast cells into dermis lesions was examined by H&E and TB staining (H&E; Magnification, × 400; scale bar, 50 µm) (TB; magnification,× 100; scale bar, 200 µm). c, d The number of immune cells was counted using ImageJ software. Data represent the mean ± SEM. n = 10. ^##P < 0.001 and ^###P < 0.01 vs. Normal group; ^*P < 0.05, ^**P < 0.01 and ^***P < 0.001 vs. DNCB-induced group
