Abstract:
Objective To investigate the influence of NO mixture(L-arginine,apocynin and sodium nitroferricyanide) on wound healing of diabetes mellitus(DM) mice.Methods Fifty adult male Kunming mice were induced by streptozotocin to establish type I DM model.They were then randomly divided into control group,L-arginine group(150 g/L),apocynin group(1?10-4 mol/L),sodium nitroferricyanide group(0.1 mmol/L) and NO mixture group(above components were mixed with equal ratio).Full-thickness skin wound was made and injected with corresponding drugs of 0.15 ml once every 2 days.The wounds were digitally photographed to calculate the percentage of wound closure using computer image analysis software in 1,3,5,7 and 10 d post-injury.The density of fibroblasts,the content of collagenous fibers and the neovascularization in the wound samples were measured with the aid of HE staining.Results From the third day post-injury,the wound healing rate of NO mixture group was significantly higher than that of all the other groups(P
