Histopathologic observation of treated wound with SSFAO 50%, in natura avocado oil, EFA (control positive), or petroleum jelly (control negative). (a) Tissue sections stained with Masson's Trichrome (400x magnification) to collagen fibers. Greater collagen deposition (b) and tensile strength (c) are seen in treated wound with SSFAO 50% or in natura avocado oil when compared to petroleum jelly control. Data are shown as average ± SEM. *P < 0.05 versus controls, **P < 0.01 versus controls, and ***P < 0.001 versus controls.
