Histological analysis of mouse dorsal skin and inflammatory cytokine levels. (A) Hematoxylin and eosin (HE) staining of mouse dorsal skin tissues (n = 7, scale bar = 100 μm). a: normal group; b: model group; c: positive control group; d: low-dose LELNs group; e: medium-dose LELNs group; f: high-dose LELNs group. (B) Epidermal thickness measurement (**P < 0.01 vs. M, ##P < 0.01 vs. C, n = 7). (C-E) Levels of inflammatory cytokines in dorsal skin homogenates: IL-1β (C), IL-6 (D), and TNF-α (E). (**P < 0.01 vs. M, ##P < 0.01 vs. C, n = 7).
