Transdermal Hydrogel Composed of Polyacrylic Acid Containing Propolis for Wound Healing in a Rat Model
- 12 Downloads
The aim of this study was to investigate the effect of the Carbopol® hydrogel containing propolis (CHP) on wound healing in a rat model. CHP extracts inhibited nitric oxide production induced by lipopolysaccharide in RAW264.7 cells with a concentration-dependent manner. Wounds were prepared through excision to remove full-thickness skin of rats k]and then were covered with CHP. The covered wounds showed significantly rapid contraction and closure. Histological tissue examination indicated that CHP induced advanced granulation tissue formation and re-epithelialization in the wound. These results indicate that CHP may be helpful for the promotion of wound healing.
