| 要約: | <b>Backgrounds:</b> Burn injuries present significant medical challenges due to their complexity in healing and potential for severe scarring. This study evaluates the efficacy of Manuka honey in accelerating burn wound healing compared to conventional antibiotic ointments. <b>Methods:</b> Using a porcine model resembling human skin, nine Landrace breed female pigs with standardized deep dermal burns were treated with either Manuka honey in alginate or a combination of antibiotic ointments. Wound healing was assessed through macroscopic evaluation, a histopathological analysis, and immunohistochemical staining over a 60-day period. <b>Results</b>: Our findings indicate that the Manuka honey treatment was associated with significantly increased collagen density in the treated wounds compared to the control group (<i>p</i> < 0.05). The immunohistochemical analysis revealed lower macrophage activity (Iba1 staining) and a reduction in Ki67 expression on days 10 and 17 in the Manuka honey group, suggesting a more rapid transition toward tissue remodeling. The quantitative analysis showed a trend toward delayed epithelialization and increased inflammation in the control group, while wounds treated with Manuka honey exhibited faster reepithelialization and improved epidermal regeneration. However, additional studies are required to further assess collagen fiber organization and overall dermal architecture. <b>Conclusions:</b> These findings support the potential of Manuka honey as a beneficial treatment for burn wound healing, with evidence of enhanced reepithelialization and collagen deposition. Further research, including clinical trials, is necessary to fully elucidate its role in clinical practice and optimize treatment protocols.
