Abstract | ||
Advanced wound therapies are needed to enhance healing beyond standard care. We compared autologous platelet-rich plasma (PRP) with zinc oxide nanoparticles (ZnO NPs) for full-thickness cutaneous wound repair in rabbits. Thirty-six male New Zealand White rabbits (n = 12/group) received topical PRP, ZnO NPs, or saline on two standardized dorsal wounds (20 mm in diameter). Treatments were applied once daily for 5 days, then on alternate days until closure or Day 21. Both treatments accelerated healing versus control. On Day 15, mean closure was 95.6% (PRP), 89.7% (ZnO NPs), and 76.4% (control; all P < 0.001 vs control). Time to ≥99% closure was 17.3 ± 2.1 (PRP), 19.8 ± 2.4 (ZnO NPs), and 23.7 ± 3.2 days (control); PRP was faster than ZnO NPs (P = 0.007). PRP yielded higher angiogenesis and VEGF expression at Day 14 (198.5 ± 24.8 vs 168.9 ± 22.1; P = 0.008) with favorable modulation of TNF-α. Both modalities were safe; PRP showed greater overall efficacy. | ||
