Abstract

Diabetes is connected with diminished wound healing, that makes patients liable to continuing difficult wounds. Metal nanomaterials as single conjugates have established to keep possible properties of wound when metal nanoparticles are coupled with other wound covering materials. This study aimed to investigate a possible role of cotton fabrics full with silver nanoparticles (AgNPs) to enhance wound healing in diabetic model induced by streptozotocin (STZ).Animals were classified into four groups including the wounded group that were equivalently covered with sterile dressing that made of cotton fabric which had been saturated with different concentrations of silver nanoparticles, and the control group that was preserved with only cotton covering without any treatment (blank group); percent of wound contraction in different studied groups was estimated. Plasma nitric oxide (NO), malodialdehyde (MDA), reduced glutathione (GSH) were measured. Serum neutrophil elastase and nuclear factor kappa b (NF-κb) were assayed by ELISA. Homocystiene (Hcy) was estimated by HPLC. Our results revealed an elevation in wound area, MDA, NF-κb, Hcy, and elastase in the wound group compared to treated groups concomitant with a decrease in plasma nitric oxide and reduced glutathione activities, while treatment with AgNPs significantly ameliorated these parameters in treated group compared to blank group. AgNPs showed high wound contraction rates according to their used concentration .In conclusion; AgNPs have gained considerable attention amongst researchers in wound healing applications, owing to their physicochemical and biological properties. AgNPs promote wound healing and effectively control the growth of microorganisms at the wound site, and this strategy plays an important role in the treatment of wounds.
