Abstract
Introduction
Burns are the fourth most common accidental injury worldwide, predominantly occurring in developing countries. Wound healing in burns involves reduced cytokine secretion but increased chemokine and growth factor production compared to surgical wounds. Keratinocyte growth factor (KGF) regulates epidermal regeneration, an essential process in wound healing; while epidermal stem cells (ESCs) play a crucial role in wound closure and have potential for cell therapy. Negative pressure wound therapy (NPWT) promotes healing by improving blood flow, enhancing re-epithelialization, and reducing infection risk. This study investigates the effects of NaCl 0.9 %, intermittent and continuous NPWT, and silver sulfadiazine on ESC and KGF levels in deep dermal burns.
Method
Six male Yorkshire pigs received 20 deep dermal burns on the flank and dorsum, divided into four treatment groups: NaCl 0.9 %, continuous NPWT, intermittent NPWT, and silver sulfadiazine. Samples were collected on days 1, 3, 7, 14, and 21. ESCs were evaluated using CK19 immunohistochemistry as a marker. KGF levels were measured via ELISA. Data were analyzed with ANOVA, with significance set at p < 0.05.
Result
Continuous NPWT showed the highest ESC counts at the wound edge on all observation days and at the wound center on days 3 and 21, though without statistical significance. KGF levels differed significantly among the groups on days 1, 3, and 7 (p < 0.05), with the continuous NPWT group consistently showing the highest KGF levels. Statistical analysis revealed that treatment, observation day, and KGF levels significantly influenced ESC counts, accounting for 45 % of the variability (p < 0.05).
Conclusion
The continuous NPWT group demonstrated significantly elevated KGF levels on days 1, 3, and 7, which corresponded to a significant increase in ESC. Further research is warranted to confirm these findings.
期刊介绍:
Burns aims to foster the exchange of information among all engaged in preventing and treating the effects of burns. The journal focuses on clinical, scientific and social aspects of these injuries and covers the prevention of the injury, the epidemiology of such injuries and all aspects of treatment including development of new techniques and technologies and verification of existing ones. Regular features include clinical and scientific papers, state of the art reviews and descriptions of burn-care in practice.
Topics covered by Burns include: the effects of smoke on man and animals, their tissues and cells; the responses to and treatment of patients and animals with chemical injuries to the skin; the biological and clinical effects of cold injuries; surgical techniques which are, or may be relevant to the treatment of burned patients during the acute or reconstructive phase following injury; well controlled laboratory studies of the effectiveness of anti-microbial agents on infection and new materials on scarring and healing; inflammatory responses to injury, effectiveness of related agents and other compounds used to modify the physiological and cellular responses to the injury; experimental studies of burns and the outcome of burn wound healing; regenerative medicine concerning the skin.
