No. of bitstreams: 1 texto completo.pdf: 2395088 bytes, checksum: 005286bddfe20cd81f6646f736142ce4 (MD5) Previous issue date: 2016-10-03 / Fundação de Amparo à Pesquisa do Estado de Minas Gerais / Objetivo: Investigar o efeito da aplicação tópica da pomada à base de Strycnos pseudoquina nas concentrações 5 e 10% na cicatrização de feridas cutâneas em ratos diabéticos. Material e Método: Amostras de S. pseudoquina foram coletadas no Município de Rio Verde, Goiás, Brasil e em seguida submetido a prospecção fitoquímica. O extrato foi emulsificado em lanolina nas concetrações 5% e 10%. Foram utilizados trinta ratos Wistar que após a indução do diabetes com estreptozotocina, foram divididos em 5 grupos de 6 animais: Sal: feridas tratadas com 0,9% de solução salina; VH (veículo da pomada): feridas tratadas com 0,6 g de creme de lanolina; SS (Sulfadiazina de Prata): feridas tratadas com 0,6 g de creme de Sulfadiazina de Prata (0,01%); ES5: feridas tratadas com pomada a base de S. pseudoquina (5%); ES10: feridas tratadas com pomada a base de S. pseudoquina (10%). Três feridas circulares de 12 mm de diâmetro foram realizadas no dorso dos animais e fragmentos das feridas foram retirados para análises histológicas e bioquímicas a cada 7 dias durante 21 dias. Resultados: Os grupos que receberam o extrato de S. pseudoquina nas concentrações 5 e 10% apresentaram maior taxa de fechamento das feridas, maior quantidade de células, vasos sanguíneos e aumento do colágeno III e I. Os marcadores de estresse oxidativo foram menores nos grupos ES5 e ES10, e os níveis de enzimas antioxidantes foram maiores nestes mesmos grupos. Conclusão: Os resultados deste trabalho demonstraram que a aplicação tópica de pomada à base de S. pseudoquina promove um reparo cutâneo rápido e eficaz em ratos diabéticos / Objective: Investigate the effect of topical application of the ointment of Strychnos pseudoquina in concentrations of 5 to 10% in the skin wound healing in diabetic rats. Material and Methods: Samples of S. pseudoquina were collected in Rio Verde, Goiás, Brazil, and then submitted to phytochemical prospection. The extract was emulsified in lanolin at concentrations of 5% and 10%. Thirty rats were used which after diabetes induction with streptozotocin, were divided into 5 groups of 6 animals: Sal: wounds treated with 0.9% saline solution; VH (Ointment vehicle): wounds treated with 0.6 g of lanolin cream; SS (Silver Sulfadiazine): wounds treated with 0.6 g of silver sulfadiazine cream (1%); ES5: wounds treated with ointment base S. pseudoquina (5%); ES10: wounds treated with ointment base S. pseudoquina (10%). Three circular wounds of 12mm in diameter were made on the animal‟s back and fragments of the wounds were removed for histological and biochemical analysis each 7 days for 21 days. Results: The groups that received concentrations of 5 and 10% of S. pseudoquina extract had higher closing rate of wounds and increase of cells, blood vessels, collagen III and I. The oxidative stress markers were lower in the groups ES5 and ES10 and levels of antioxidant enzymes were higher in the same groups. Conclusion: The results of this work have shown that topical application of S. pseudoquina ointment promotes fast and effective skin repair in diabetic rats.
