Background: Wound healing, as a normal biological process in the human body, is achieved through four precisely
and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling. Growth factors released in
the traumatized area promote cell migration into the wound area (chemotaxis), stimulate the growth of epithelial
cells and fibroblasts (mitogenesis), initiate the formulation of new blood vessels (angiogenesis), and stimulate matrix
formation and remodeling of the affected region. One of factors that effects on wound healing is a sex hormones
and one of these hormones is an estrogen hormone. A wide range of cutaneous cell types (eg, fibroblast,
endothelial, epithelial, and inflammatory) expressed estrogen receptors, indicating potential estrogen
responsiveness.
Materials and methods: Thirty two female New Zealand rabbits were used in this study. All animals were
ovariectomized, and incisional wounds were done on the right (experimental for estrogen hormone application) and
left (control) sides of face for each animal, the control side was left to heal normally. Histological assessment
regarding the count of inflammatory cells was performed for healing intervals (3, 7, 10, 14 days).
Results: Topical estrogen hormone application revealed enhancement of wound healing by reducing wound size
and stimulating matrix deposition in comparison to control.
Conclusion: Topical estrogen cream application results in significant progress of cutaneous wound healing, leaving
no scar or crust formation and can minimize the probable wound complications |
