(A) C57BL/6 mice fed with a niacin-deficient diet and or a normal control diet were exposed to UVB radiation and examined for ear swelling responses at the indicated time points. Data are presented as means ± SEM. *, P < 0.05. (B) H&E staining of ear samples collected from mice fed with a niacin-deficient or a control diet after UVB irradiation. Original magnification, x200. Scale bar 100 μm. (C) The histological findings were scored. Data are presented as means ± SEM. *, P < 0.05.
