Background
The healing process of burns includes coagulation, inflammation, and remodeling. Vascular endothelial growth factor (VEGF) is involved throughout this healing process. Stem cells from the platelet-rich plasma (PRP) with stromal vascular fraction (SVF) can increase concentrations of growth factors, including VEGF. This is expected to accelerate burn healing. The aim of this study was to determine the effect of a combination of PRP and SVF on VEGF levels in a rats model of deep dermal burn wound healing.
Materials and methods
This is an experimental research study in rats using a post-test control group design with 4 groups: A) control, B) Vaseline, C) topical PRP and SVF, and D) PRP and SVF injection. Burn wounds were induced according to the modified Guo method.
Results
In a rats model of deep dermal wound healing, topical Vaseline significantly increased serum VEGF compared to control. Topical application and injection of stem cells also significantly increased serum VEGF compared to control and Vaseline. The VEGF concentration was significantly higher following injection of PRP and SVF, suggesting that the injection route is more effective at increasing VEGF levels compared to the topical application of stem cells.
Conclusion
The combination of PRP and SVF, either by injection or topical application, can increase VEGF levels during the healing process from deep dermal burns.
Background: One of the problems with burn patients is the impairment of host immunity, which makes difficult to treat. In burns, immunoglobulinA has demonstrated to decrease. Immunoglobulin A is the main product of mucous immune system, which increases viral clearance and decreasesbacterial adhesion in the intestine. Probiotics consist of living microflora, which control the balance of lactobacilli and bifidobacteria in the intestine.Instead of producing organic component, increasing the acidity of intestine, mucin and bacteriocin, they also activate the intestinal immune systemand secretory immunoglobulin A (sIgA). The goal of this study was to propose that regular intake of probiotic might help to improve the mucousimmune system, especially sIgA in intestines in burn patients.Methods: An experimental, double-blind, controlled clinical trial was carried out in 33 burn patients. Those patients were divided into two groups.The first group was given daily probiotic and the second group was given only placebo for 10 days. The treatment began on the 4th day admission, andthen, the degree of sIgA was evaluated before treatment and day 14 from fecal specimen.Results: Significant differences between probiotic and control group were observed (p<0.0001). The degree of sIgA in the probiotic group increased61.25%, and in the control group, it decreased to 36.80%.Conclusion: The mucous immune system, especially sIgA, increases by probiotic intake.
