EFFECT OF PHOTOBIOMODULATION ASSOCIATED WITH CELL THERAPY IN THE PROCESS OF CUTANEOUS REGENERATION IN THIRD DEGREE BURNS IN RATS

Due to the complexity involved in the healing process of full-thickness burns, the literature looks for alternatives to optimize tissue reconstruction. The objective of this study was to explore the action of PBM associated with MSCs in the healing process of third degree burns. A total of 96 male Wistar rats were used, distributed in four groups with 24 animals each: Control Group (CG); Laser Group (LG); Cell Therapy Group (CTG); Laser Group and Cell Therapy (LCTG). The burn was performed with aluminum plate (150 degrees C). We performed analysis of wound contraction, histology, immunohistochemistry, birefringence analysis and immunoenzymatic assay to evaluate tissue quality. Our results demonstrate that the association of the techniques is able to accelerate the repair process, modulating the inflammatory process, presenting a cutaneous tissue with better quality. Thus, we conclude that the use of PBM associated with cell therapy is a promising treatment in the repair of total thickness burns.
