Evaluation of skin clinical observation at the end of experiment period. (a) (left) Pinch test was performed according to the method described by Tsukahara. (a) (right) Macroscopic changes of mice with different treatments were performed. (b) Recovery time in the pinch test of different groups was evaluated. (c) The trend of macroscopic changes reflected in the changes of visual scores was expressed according to the method described by Bissett et al. (d) Water contents of mice skin with different treatments were measured. (e) Skin-fold thickness of dorsal skin of different experiment groups was measured using a caliper. Data represents means ± SD (). compared with the SC group; compared with the VC group. NC, normal control; SC, sham control; MC, model control; VC, vehicle control.
