Abstract
Platelets in PRP are used for their functions in the initiation and regulation of the wound healing process and are used for the repair of injured tissues and the rejuvenation of healthy tissues. In this study, we evaluated the effect of a single dose platelet-rich plasma on skin wound healing and we demonstrated the effect of platelet-rich plasma on skin wound healing by measuring changes in the wound tensile strength.
Material and methods: A total of 8 incisions, each 3 cm long, were made on the back skin on both sides of the vertebral column of 12 rabbits. After suturing their backs with staples, platelet rich plasma (PRP) was injected into the edges of the wounds on the left side and saline solution (saline) was injected into the edges of the wounds on the right side. The tensile force that causes wounds to rupture by applying tension was measured on the 7th, 14th, 21st, and 28th days with the help of a special home-designed device.
Results: The mean PRP enrichment was 3.19 fold over peripheral blood. The saline to PRP tensile strength ratios on the 7th, 14th, 21st, and 28th days were calculated as 75.7%, 104.0%, 105.3% and 86.5%, respectively. Overall, the difference in the tensile strength for wounds that had received saline or PRP was in-significant.
Conclusion: The application of PRP increases the tensile strength of the wound in the early period. It is possible to measure the tensile strength precisely in in vivo studies with economical home-designed devices.
