Abstract
Objetivos: verificar o efeito do óleo de copaíba no colo uterino de ratas ooforectomizadas. Métodos: foram utilizadas 120 ratas adultas distribuídas em 4 grupos: as que receberam aplicação de óleo de copaíba, óleo de milho, água e um grupo sem tratamento. Todos os animais foram submetidos a ooforectomia bilateral e posteriormente mantidos em gaiolas por um período de 20 dias antes de iniciar a aplicação das substâncias. Estas foram administradas via vaginal na dose de 0,3 ml, diariamente, uma vez ao dia até os dias determinados para o sacrifício (7º, 14º e 21º), sendo sacrificados de cada grupo 5 animais por dia. Resultados: todos os animais do grupo copaíba apresentaram epitélio exuberante, estratificado pavimentoso queratinizado, em torno de 10 fileiras de células epiteliais, e lâmina própria com tecido conjuntivo denso, rico em fibroblastos, fibras colágenas, inúmeros vasos sanguíneos e alguns leucócitos. Conclusões: o óleo de copaíba utilizado neste modelo experimental promoveu espessamento do epitélio do colo uterino, que se apresentava pavimentoso estratificado com queratinização, além do espessamento progressivo deste epitélio no decorrer dos dias de estudo.
Purpose: to study the effect of copaíba oil on the uterine cervix of oophorectomized rats. Method: 120 female adults were used, divided into four groups: control, water, corn oil and copaíba oil. All animals were submitted to bilateral oophorectomy, and kept in cages for twenty days before applying the substances. These substances were applied by vaginal route at a dose of 0.3 ml, once a day until the predetermined day of sacrifice (7, 14 e 21 days). Results: the animals from the copaíba oil group showed on all days of the study exuberant, keratinous stratified squamous epithelium with about 10 epithelial cell layers and the chorion with conjunctive tissue, fibroblasts, collagen fibers, blood vessels and some leukocytes. Conclusions: The copaíba oil used in this experimental model promoted a thickening of the epithelium, which was keratinous stratified squamous, and epithelium increase was progressive along the study.
