Background
Platelet-rich plasma (PRP) contains numerous growth factors to
promote wound healing and angiogenesis. The aim of this study was to gain
further information about the benefits of platelet-rich-plasma for healing
cutaneous acute to chronic wounds.
Methods
A total of 30 New Zealand albino rabbits (n = 15/group) were randomly assigned to two experimental groups:
control group, and PRP group. Bilateral resection defects measuring 3 cm were
surgically created on the dorsolateral of the cutaneous in animals and the
defects were randomly divided into two mentioned groups. Wound area,
neovascularization, size and epithelialization were compared on days 7, 14 and
21 post-wounding. Histopathological analyses were conducted on 15 specimens from
each group after sacrifice by the cellular aspects of the regeneration of the
tissue.
Results
Our results were indicated that the wound area of PRP was smaller
than that in the non-treated group on days 7, 14 and 21. Furthermore, a
significant decrease of the wound size
was observed in PRP groups that were significantly
greater than that in the control group. A significant increase of
the mean vascular density was noted in the PRP treated groups compared to the
control groups at day 14 and especially day 21. This results indicated that PRP
treated group’ enhanced angiogenesis at the wound beds as compared to no
treatment group.
Conclusion
These results could be useful for researchers in the growing fields
of tissue repair and experimental wound healing. Further studies will be
essential to determine the role of PRP in clinical practice.
