Histopathology of rat skin wounds on day 4, 8, 12 and 16 of the wound incisions stained with Masson's trichrome. (a) Micrographs of sections of wound incision rat skin treated with commercial antibacterial gel (top) and with GG/Cur-AgNPs (bottom). Collagen is indicated by the blue-green colour. (b) The percentage of collagen deposition (area of blue-green colour) was measured in 10 high-power field (HPF) (400 × magnification). Data were expressed as mean ± SEM (n = 3/time point). *P < 0.05 and **P < 0.01 compared to the control on the day of experiments. Scale bar = 40 μm.
