Moisturizing effect of FRB, FSB and FSC on UVB-induced hairless mice. (A) TEWL in dorsal skin and (B) β-glucosidase activity. To estimate the TEWL, the dorsal skin of each mouse was examined using an appropriate probe. β-glucosidase activity was measured via an enzyme assay that monitored the conversion of 4-methylumbellifery-β-D-glucopyranoside to 4-methylumbelliferone. All values are presented as the mean ± standard deviation. One-way analysis of variance and Scheffe's post-hoc test were used to control for multiple comparisons. ^aP<0.05, ^bP<0.01 and ^cP<0.001 vs. normal control mice. TEWL, transepidermal water loss; FRB, fermented rice bran; FSB, fermented soybean cake; FSC, fermented sesame seed cake; UVB, ultraviolet B; RA, retinoic acid.
