ABSTRACT

 

Motaghi S, Sadeghi M, Seyedin S, Kheirandish R, Nazem MN,  Mirtadzadini, M, Sepehri GR, Oloumi MM., Effect of Fraxinus excelsior on dermal collagen during wound healing in adult Oryctolagus caniculus rabbits, Onl J Vet Res., 21(1):8-14, 2017.  Effect of Fraxinus excelsior alcoholic extract on thickness of dermal papillary collagen during healing in 4 male and 3 female adult Oryctolagus caniculus rabbits is described. Under anesthesia, 4 wounds were created on each rabbit and treated daily with 0.2g eucerin as negative controls, phenytoin 1% positive controls and Fraxinus excelsior 10%, and 20% in eucerin-based creams for 20 days. At euthanasia on day 21, skin sections were taken and stained with Masson's trichrome to measure thickness of collagen bundles and hematoxylin-eosin (H&E) for histopathology. On Masson's trichrome, average diameter of 10 collagen bundles in every 10 fields were measured by digital lens Dino-eye, AM-7023, 5Mp and H&E sections for inflammatory cells and angiogenesis. Results suggested that Fraxinus excelsior 10% cream increased (P < 0.01) collagen bundle thickness in the papillary layer compared with eucerin but had no effect on collagen in the reticular layer. As expected, phenytoin increased (P < 0.01) collagen thickness in both reticular and papillary layers.  .
