Background:
To evaluate the process of cutaneous wound healing, experiments have been conducted. However, to date, what modern wound dressings are suitable remains unclear. Therefore, this study aimed to compare the healing process in different modern wound dressings to determine their suitability in experimental acute wound and chronic diabetic wound.
Materials And Methods:
Twelve C57BL/6J mice and eleven db/db mice were subjected to full-thickness wound injuries. The mice were divided into the following four groups: hydrocolloid, form, film, and gauze groups in both wild-type and db/db mice. Wound healing was assessed until day 14.
Results:
In the wild-type groups, all wounds were healed and completed re-epithelialization by day 14. However, the wound surface was dry, and the periwound was hypercontracted in the wild-type-form and wild-type-gauze groups. In the db/db groups, wounds were not healed until day 14. Wound exudates in the db/db-hydrocolloid group were abundant and gradually increased until day 14. Wound exudates in the db/db-film group were present until day 14. Conversely, in the db/db-form and db/db-gauze groups, the wound surface was dry, and the periwound was hypercontracted.
Conclusion:
These results showed that hydrocolloid and film dressings are suitable modern wound dressings for the mice wound models of acute wound and chronic diabetic wound. Moreover, using either hydrocolloid or film dressing depending on the purpose of the study on cutaneous wound healing in diabetes is necessary.
