Figure 2

Histological analysis for epidermal and dermal thickness in dorsal skin of TEA-treated mice against UVB-induced skin damage. (a) Haematoxylin and eosin staining and its histogram estimated for (b) epidermal and (c) dermal thickness. TEA treatment significantly suppressed increase in epidermal thickness and decrease in dermal thickness in UV irradiated mice. and versus normal mice; versus UV alone irradiated mice. Scale bars = 200 μm. Nor, normal; TEA, thread embedding acupuncture; UV, ultraviolet B.
