Abstract
The aim of this study was to analyze the healing action of low-intensity laser therapy associated with Himatanthus drasticus in wound healing in mice. The study was experimental, analytical, controlled, randomized, and prospective. Twenty Wistar rats were divided into four groups: control with injury, injury + laser, wound + Himatanthus drasticus, and wound + laser + Himatanthus drasticus. The animals underwent surgical skin wounds on their backs, and different treatments were applied based on the group. The healing process was evaluated histologically through the analysis of collagen fibers, neovascularization, and inflammatory reaction. The results showed that low-intensity laser therapy and Himatanthus drasticus treatment improved the healing process in terms of collagen synthesis, decreased inflammatory cell migration, fibroblast proliferation, neovascularization, wound size reduction, and edema reduction. However, the combination of laser and Himatanthus drasticus did not show significant improvement compared to individual treatments. There were no statistical differences in polymorphonuclear cells between the treatment groups. Low-intensity laser therapy and Himatanthus drasticus have demonstrated positive properties in improving the healing process. Further research is needed to better understand their individual and combined effects. The study contributes to the exploration of alternative wound healing methods and encourages further investigation in this field.
