A new experimental delayed wound healing model in rabbits

Area of Science:

• Regenerative Medicine
• Wound Healing Research
• Animal Models

Background:

• Chronic wounds present significant clinical challenges, demanding effective treatments.
• Current treatment strategies for chronic wounds are often difficult and expensive.
• There is a need for reliable animal models to study delayed wound healing mechanisms.

Purpose of the Study:

• To develop and validate a new animal model for delayed wound healing.
• To investigate the impact of panniculectomy combined with burn injury on wound healing.
• To assess the quality of scar formation in the developed model.

Main Methods:

• A surgical procedure involving panniculectomy was performed on New Zealand rabbits.
• Third-degree burn injuries were inflicted on healed panniculectomy sites and control sites.
• Wound healing time and scar characteristics were histopathologically evaluated.

Main Results:

• Wounds in the panniculectomy group took an average of 43.20 days to heal, compared to 32.80 days in the control group (p < 0.05).
• The panniculectomy group exhibited delayed wound healing, broader, and more irregular scars.
• The addition of panniculectomy significantly impaired wound healing and reduced scar quality.

Conclusions:

• The developed animal model effectively demonstrates delayed wound healing and compromised scar quality.
• This model provides a simple, economical, and effective method for studying delayed wound healing.
• Findings highlight the potential of this model for future research into wound healing interventions.
