UVC induced dose-dependent increases in the green AF intensity of mice’s skin. A, B. Irradiation with 0, 0.3, 0.6 and 0.9 J/cm² UVC produced significant and dose-dependent increases in the green AF of the mice’s skin. C. The dosages of the irradiation were highly correlated with the levels of the green AF intensity. D. There was a high correlation between the levels of the green AF intensity and 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. Eighteen - 24 h after the irradiation, the skin’s green AF was determined under a confocal microscope. N = 9. *, P < 0.05; ***, P < 0.001. Scale bar = 20 μm.
