摘要：The porcine model was used to investigate the wound healing process. 116 partial and full-thickness wounds were induced on the back of the animals using the CO2 Three local dressing agents were tested: Povidone Iodine, Silver Sulphadiazine and MEBO ointments. The following parameters were evaluated: physical examination, photography, pH, transepidermal water loss and moisture of the wound, planimetry and histological assessment of injury. The measurement of different parameters revealed that partial-thickness burn wounds were better assessed using Transepidermal Water Loss (TEWL), while full-thickness ones are better assessed using planimetry, measuring the surface of the wound. MEBO significantly accelerates the wound healing process of partial- (inflicted by CO2 Laser) and full-thickness excised wounds when compared to other local agents applied on wounds similar in size, extent and cause and the control group.
摘要：Cutaneous delayed wounds are a challenging clinical problem, and vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) exhibit key roles in wound healing. Moist exposed burn ointment (MEBO), a Chinese burn ointment with a USA patented formulation, has been reported to promote chronic ischemic and neurogenic ulcer healing in patients; however, the underlying mechanisms remain unclear. In the present study, MEBO significantly promoted the formation of granulation tissue in cutaneous excisional wounds, shortened the time of wound healing, and increased neovascularization and the number of fibroblasts. Furthermore, as well as enhancing the protein expression, MEBO application also increased the gene expression of VEGF and bFGF. The results indicate that MEBO promotes cutaneous excisional wound healing by at least partially enhancing VEGF and bFGF production, implicating the potential uses of MEBO for delayed cutaneous wound healing.
摘要：Background: The incidence of diabetes-related wounds is widespread, and the treatment is challenging. We found that Moist Exposed Burn Ointment (MEBO) promotes the healing of diabetes-related wounds, but the mechanism is not clear.Methods: This study aimed to explore the mechanism of MEBO on diabetic wound healing, which may be related to the promotion of re-epithelialization. A full-thickness skin resection model was established in streptozotocin(STZ)-induced diabetic mice. MEBO and Kangfuxin (KFX) were applied to the wound area, and the wound healing rate was analyzed by photographing. The granulation tissue and epidermal thickness, the collagen remodeling rate, and the expression of cytokeratin 10 (CK10), cytokeratin 14 (CK14), Ki67,CollagenⅠ,and Collagen Ⅲ in the regenerated skin were detected by H&E staining, Masson staining, and immunofluorescence staining, respectively. MEBO and KFX were applied to human immortalized keratinocytes (HaCaT)、mouse dermal fibrolasts (MDF) cells, and cell viability, cell migration, and differentiation were determined by CCK-8, scratching assay, RT-qPCR, and Western blot(WB), respectively. Results: We found that MEBO significantly promoted the formation of wound granulation tissue and collagen remodeling in diabetic mice. The application of MEBO to diabetic wounds not only promoted the formation of hair follicles and sebaceous glands but also promoted the expression of Ki67, CK10, and CK14 in epidermal cells. MEBO had no significant effect on the differentiation process of keratinocytes.Conclusions: Our study further proved that MEBO plays a positive role in diabetic wound healing, and its excellent ability to promote re-epithelialization may be an important reason for promoting wound healing.
