The Mechanism of Burn Regenerative Therapy and Wound Healing
XU Rong-xiang, XIAO Mo(China National Science and Technology Center for Burns 中国烧伤创疡杂志 2003

摘要:Objective: From molecular, cell and systemic clinical treatment three levels, this report revealed the mechanism of wound healing, the basic theory and the importance of clinical practice for the Burn Regenerative Therapy with MEBT/MEBO (BRT & MEBT/MEBO).Method: This report analyzed the importance and clinical curative effect for standardized appliance of BRT & MEBT/MEBO from two key points: 1) Liquefaction of necrotic tissue from burn wound; 2) Skin regenerationin situ. Result: There are three necessary conditions for skin physiologically repair and regeneration of burn wound: 1) The formation of moist physiological environment on burn wound; 2) The material foundation of life regenerative substances and histology for keratin-19 stem cells' regenerationin situ; 3) Standardized procedures and appliance of BRT & MEBT/MEBO, which is the guarantee of burn wound healing physiologically. Conclusion: The theory of “Potential Regenerative Cell" and the technique of “Stem cellin situregeneration" are ...

摘要:Objective: To investigate the mechanism of the effect of Moist Exposed Burn Therapy (MEBT) and Moist Exposed Burn Ointment (MEBO) on the spontaneous repair and healing of superficial third degree burn wound involving fatty layer. Method: A series of skin tissue samples were taken from deep burn wounds of 2 cases. Immunocytochemistry method, biotin-avidin DCS system, and indirect immunofluorescence technique were applied. Mouse anti-human keratin type 19 monoclonal antibody was used to detect regenerative epidermal stem cells in wound tissues. Results: Epidermal regenerative stem cells emerged at 24 hours post burn, and the number of epidermal regenerative stem cell increased on day 4 post burn. On days 7 and 14 post burn, the number of epidermal stem cells increased to the peak level. On days 21 and 28 post burn, it decreased and disappeared gradually as burn wound progressed to healing. Conclusion: MEBT/MEBO has the effect of promoting the activation and proliferation of epidermal regenerative stem cells in ...

摘要:Moist Exposed Burn Ointment (MEBO?) is widely used topical agent applied on skin burn. This study investigated the effect of MEBO topical application on activation and proliferation of epidermal stem cells through the immunohistochemical localization of cytokeratin 19 (CK19) as a known marker expressed in epidermal stem cells. Biopsies from normal skin and burn wounds were taken from 21 patients with partial thickness burn 1, 4, 7, 14, 21, and 28 days after treatment with MEBO. Tissue sections were prepared for histological study and for CK19 immunohistochemical localization. In control skin, only few cells showed a positive CK19 immune-reaction. Burned skin showed necrosis of full thickness epidermis that extended to dermis. Gradual regeneration of skin accompanied with an enhancement in CK19 immune-reactivity was noted 4, 7, 14 and 21 days after treatment with MEBO. On day 28, a complete regeneration of skin was observed with a return of CK19 immune-reactivity to the basal pattern again. In conclusion, the enhancement of epidermal stem cell marker CK19 after treatment of partial thickness burn injuries with MEBO suggested the role of MEBO in promoting epidermal stem cell activation and proliferation during burn wound healing.
