Effects of dressing and rinsing on wound healing. (A) Reepithelialisation; (B) capillary number. Lane 1: wounds open for 7 days, n = 9; lane 2: covered wounds with sterilised transparent dressing, n = 14; lane 3: covered wounds with sterilised transparent dressing and rinsed with saline, n = 14; lane 4: covered wounds with sterilised dry cotton gauze and rinsed with saline, n = 10. *P < 0·05. The data obtained were analysed by analysis of variance and the Tukey–Kramer test. Each bar represents mean ± standard error of the mean. (C) Representative histopathology of open and closed wounds on day 7. Group 1: an open wound; group 2: a covered wound with sterilised transparent dressing. Arrow heads indicate the original wound edges (haematoxylin and eosin staining, scale bar: 500 µm).
