Skin parameters and intercellular lipids of SC in GK and Wistar rats. Transepidermal water loss (TEWL) (A), stratum corneum (SC) hydration (B), and surface pH (C) in the lateral abdominal skin were analyzed as skin parameters. As intercellular lipids of SC, the contents of free fatty acids (FFAs) (D), ceramides (CERs) (E), and cholesterol (CHOL) (F) were analyzed. Data are expressed as dots for individual values and bars for mean ± S.D. (n = 4–6)
