Copaíba oil Archives - Revista Brasileira de Ginecologia e Obstetrícia

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.
