Resumo

OBJECTIVE To test the hypothesis that platelet-rich plasma (PRP) improves wound healing in rabbits by analyzing morphologic alterations in lesions with the use of PRP alone or combined with rosuvastatin (RSV). METHODS Eight adult male New Zealand rabbits were used in this study. Researchers created four wounds on the back of each rabbit with an 8-mm punch. The control wound was treated with a 0.9% sodium chloride solution. Experimental wounds were treated with PRP, RSV, or both PRP and RSV. Dressings were changed with a new application of PRP and RSV every 4 days for 16 days. Wounds were biopsied on days 0, 7, 10, 14, and 17 for histopathologic evaluation of the scar tissue. MAIN RESULTS Histopathology revealed reepithelialization in 100% of wounds treated with PRP alone after 17 days of treatment, compared with 50% of wounds treated with RSV alone and 75% of the wounds treated with PRP and RSV. Further, combining RSV and PRP reduced blood loss. The use of PRP alone induced 100% neovascularization, compared with 50% and 62.5% in wounds treated with PRP and RSV and RSV alone, respectively. All experimental wounds had a higher percentage of collagen fibers on day 17 postlesion when compared with control wounds (78.27% +/- 4.69%). There were no significant differences among treatments; however, wounds treated with RSV alone had the lowest amount of collagen fibers (85.98% +/- 3.51%). Wounds treated with PRP alone or PRP and RSV had 90.07% +/- 6.20% and 90.76% +/- 3.51% collagen fibers, respectively. CONCLUSIONS The results of this study indicate that PRP elicits higher healing activity in the first 7 days postlesion. Treatments with RSV alone or RSV and PRP did enhance other healing phases.
