Avaliação terapêutica das pomadas do polissacarídeo do Anacardium occidentale L. e do extrato em pó da Jacaratia corumbensis O. kuntze em feridas cutâneas produzidas experimentalmente em caprinos (Capra hircus L.) :aspectos clínicos, bacteriológicos e histopatológicos

Abstract

The cutaneous losses are frequent in domestic animals, having as aggravating different etiologies, the extension of the wound and the costs with the treatment. With the objective of evaluating the therapeutic effect of the ointments of polysaccharide of the cashew tree Anacardium occidentale L. (policaju) and the powdered extract of Jacaratia corumbensis O. kuntze (jacaratia) in the treatment of cutaneous wounds 20 goats were used, with medium weight of 24Kg in which six cutaneous flaws of 4cm2 were produced in the right and left thoracic area, being the one of the right hemi-thorax of the 20 animals considered the control wounds, which received topical application of sterile lanolin, the ones located in the left hemi-thorax of ten animals that received topical application of the ointment of policaju and the ones located in the left hemi-thorax of the other ten animals that received topical application of the ointment of jacaratia. The curative was made daily, applying 1ml of each formulation at each wound bed in both groups. The cutaneous lesions were also submitted to clinical, histopathological and microbiological evaluations. For accomplishment of the histopathological exam, the wounds were submitted to biopsies in different and previously determined times; in the ones produced cranially the biopsy was accomplished at the 7th day, the lesions located in the medium-ventral area at the 14th day and on the ones located caudally the biopsy was accomplished at the 28th day of pos-surgical evolution. The clinical evaluations were accomplished using a descriptive scale for evaluation of the parameters, being observed in the groups the presence of hyperemia and circumscrite edema to the lesion until the 3rd day of pos-surgical evolution; granulation tissue starting from the 4th day and cicatricial tissue starting from the 6th day. At the 21st postoperative day all the wounds were reepithelized. The microbiological exam was accomplished in the moment of the wounds production, when bacterial growth was not observed and in the biopsies moments, identifying the presence of Staphylococcus sp, Streptococcus sp, Bacillus sp, Shigella sp, Enterobacter sp and Micrococcus sp. The histopathological evaluation of the wounds revealed infiltrated inflammatory cells, neoangiogenesis, fibroblasts and collagens fibers. Was concluded that the ointments produced can be used as a treatment option for cutaneous wounds in goats.
