RESUMO:O presente trabalho investigou as atividades analgésica e antiinfl amatória do extrato metanólico de rizomas de Echinodorus grandifl orus. Para isto, foram realizados os testes de contorções abdominais induzidas por ácido acético; tempo da lambida da pata induzida por formalina; edema de pata e pleurisia induzidas por carragenina. As doses de 100, 200 e 400 mg/kg inibiram as contorções em 34,30%, 35,84% e 36,07%, respectivamente. O tempo de lambida da primeira fase foi reduzido nas doses de 200 e 400 mg/kg, enquanto a segunda fase teve redução em 400 mg/kg. As doses testadas diminuíram o edema, enquanto o volume do exsudato foi reduzido em 24,61% na dose de 400 mg/kg. As doses de 200 e 400 mg/kg diminuíram a migração leucocitária. Os resultados indicam que o extrato de E. grandifl orus testado pode constituir alvo potencial para uso em terapias da dor e da infl amação.

The present work investigated the analgesic and antiinfl ammatory activities of the methanol extract of the rhizomes of Echinodorus grandifl orus. For this purpose, acetic acid writhing, paw licking induced by formalin, carrageenan-induced rat paw edema and pleurisy tests were performed. The doses of 100, 200 and 400 mg/kg inhibited the contortions 34.30%, 35.84% and 36.07%, respectively. The lick of the paw 1st phase was reduced at the doses of 200 and 400 mg/kg, while the 2nd phase had reduction at 400 mg/kg. All doses inhibited the paw edema, while the volume of the exsudate was reduced 24.61% in the dose of 400 mg/kg. The doses of 200 and 400 mg/kg decreased the leukocytes migration. The results indicate that the methanol extract of E. grandifl orus can constitute target potential for use in therapies of the pain and infl ammation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
