| Popis: | PURPOSE: The aim of this study was to analyze the changes that occur in rats with experimental endometriosis after treatment with copaiba oil. METHODS: Experimental endometriosis was induced in rats. The experimental group received copaiba oil (Copaiferalangsdorffii) orally (0.63 mg/day), and the control group received a 0.9% sodium chloride solution orally (1 ml/100 g of body weight/day). Both groups were treated with gavage for 14 days. After this period, the animals were euthanized, and the implant volume was calculated. The autologous transplants were removed, dyed with hematoxylin-eosin, and analyzed by light microscopy. RESULTS: The average final volumes were significantly different between the groups (p=0.007). There was a significant increase (p=0.012) between the initial and final volumes in the control group, whereas treatment with Copaiferalangsdorffii caused a marked reduction in endometrial growth over time (p=0.016). Histologically, 6/11 (55.00%) rats in the experimental group had a well-preserved epithelial layer, and 3 (45.00%) had mildly preserved epithelium. The control group had seven cases (58.30%) of well-preserved epithelial cells and five cases (41.70%) of mildly preserved epithelial cells (p>0.05). CONCLUSION: Copaiba oil (Copaiferalangsdorffii) appears to be a promising alternative treatment for endometriosis. OBJETIVO: O objetivo deste estudo foi analisar as mudanças que ocorreram em ratas com endometrioses experimental tratadas com óleo de copaíba. MÉTODOS: Foi induzida a endometriose experimental nas ratas. O grupo experimental recebeu óleo de copaíba (Copaiferalangsdorffii) oralmente (0,63mg/dia) e o grupo controle recebeu oralmente solução salina 0,9% (1mL/100g/dia). Ambos grupos foram tratados por gavagem por 14 dias. Depois desse período, foi realizada a eutanásia dos animais e calculado o volume do implante. Os transplantes autólogos foram removidos, corados com Hematoxilina-eosina e realizada a microscopia óptica. RESULTADOS: A média final dos volumes foi significativamente diferente entre os grupos (p=0,007). Houve um aumente significante (p=0,12) entre o volume inicial e final do grupo controle, enquanto no grupo tratado com Copaiferalangsdorffii causou uma redução acentuada no crescimento endometrial ao longo durante o período (p=0,016). Histologicamente,6 das 11 (55%) ratas do grupo experimental tinha uma camada epitelial bem preservada e 3 (45%) apresentaram epitélio levemente preservado. O grupo controle apresentou sete casos (58,3%) de células epiteliais bem preservadas e cinco casos (41,7%) de células epiteliais levemente preservadas (p>0,05). CONCLUSÃO: O óleo de copaíba (Copaiferalangsdorffii) parece ser um tratamento alternativo promissor para endometriose. |
