Avaliação dos efeitos do barbatimão (Sthyphnodendronar barbatiman), da copaíba (Copaifera officinalis) e do ipê-roxo (Tabebuia avellanedae) na cicatrização por segunda intenção de feridas cutâneas experimental em equinos

Abstract

There were used six Pantaneiro adult horses aiming to evaluate the macroscopic and histopathological aspects of cutaneous wound healing by secondary intention in surgically induced wounds and treated with barbatimão (Stryphnodendron barbatiman), copal (Copaifera officinalis ) and pau d´arco (Tabebuia avellanedae ) in a 10% ointment formulation . The control treatment was performed with isotonic sodium chloride solution . Four wounds were performed with a circular metallic "punch " on the lumbar region bilaterally of each animal. The right-sided lesions were intended for macroscopic evaluation and centripetal retraction , and the left-sided lesions for histopathological examination, which was held on the 6th and 16th day of treatment . Wounds were treated daily until complete healing . The healing was faster in the control group when compared to the group treated with herbal remedies, however, the characteristics of the healing process as neoangiogenesis, granulation tissue , fibroblasts and collagen rate were better in wounds treated with pau d´arco followed by barbatimão and copal.
