Estudo histopatológico nas córneas dos cães tratados com 2-1 fosfato dissódico de betametasona e fosfato dissódico/acetato de dexametasona, que receberam transplantes com córneas de suínos

Abstract

Ten dogs, with no definitive breed, average weight of 10 kg, were in this research. After being examined and considered healthy they received numbers, from 11 to 20 in their collars. Each dog received implantation, in the left eye, of swine comea, obtained at Casa de Banha Caçula, a slaughterhouse, and maintained in wet chamber for six hour at most. Before surgery, each animal received 4 mg of dissodic phosphate/acetate dexamethasone IM anel, once a week, one drop of dissodic phosphate betamethasone and gentamicin sulphate, four times a day, until the 28"' day, when the animais were sacrificed through painless process (Thiopental sodic + succinilcolin chloride ), and the eye that had received the implantation of swine comea was enucleated. Formaldehyde 10% was injected in the vitreous camera and after that the eye was placed in a container and the comea was removed with sclerous ring, treated and colored with hernatoxilin-eosin. Toe implantation and the comea nearby areas were analysed as well as the alterations.
