Fig. 6From: Physical, morphological, and wound healing properties of a polyurethane foam-film dressingEpidermal Staining (x100, Left photo). Epidermal Recovery Rate (right). Assuming the entire length of wound being ‘C’ and the epidermal recovery rates being ‘a’ and ‘b’ at both ends, the rate of epidermal regeneration were calculated by [(a + b)/C]*100 to represent in percent.
