UVC induced dose-dependent damage of mice’s skin. A, B. Irradiation with 0, 0.3, 0.6 and 0.9 J/cm2 UVC produced dose-dependent damage of mice’s skin. C. The dosages of the irradiation were highly correlated with the levels of the skin damage. The mice were exposed to UVC irradiation at the dosages of 0, 0.3, 0.6 and 0.9 J/cm2. Three days after the irradiation, the skin’s damage was determined by H&E staining. N = 3. *, P < 0.05; **, P < 0.01. Scale bar = 100 μm.
