ABSTRACT
The aim of the present work was to investigate the anti-inflammatory and analgesic effects of red seaweed Dichotomaria obtusata, using classic tests in mice (ear edema induced by TPA and writhing induced by acetic acid). The qualitative chemical composition of the aqueous extract (lactones, phenols, triterpenes, steroids and reduced carbohydrates) obtained from this alga was also determined. The results showed that Dichotomaria obtusata (12.5, 25 and 50 mg/kg, ip) inhibited mouse ear edema in a dose-dependent manner. In the writhing test, aqueous extract (12.5, 25, 50 and 100 mg/kg, ip and 100, 200, 400, 800 mg/kg, po) significantly reduced abdominal writhes. In conclusion, this study demonstrated the anti-inflammatory and antinociceptive activities of aqueous extract of D. Obtusata in experimental models. These results suggest that D. obtusata aqueous extract possesses therapeutic potential in the treatment of peripheral painful or/and inflammatory conditions.
RESUMO
O objetivo do presente trabalho é centrado nos efeitos antiinflamatórios e analgésicos da alga vermelha Dichotomaria obtusata por meio de clássicos testes em camundongos (edema de orelha induzido por TPA e contorção induzida por ácido acético). Também foi determinada a composição química qualitativa do extrato (lactonas, fenóis, triterpenos, esteróides e carboidratos reduzidos). Os resultados mostraram que de Dichotomaria obtusata (12,5, 25 e 50 mg/kg, ip) inibiu o edema de orelha do camundongo de forma dose-dependente. No teste de contorção, extrato aquoso (12,5, 25, 50 e 100 mg/kg, ip e 100, 200, 400, 800 mg/kg, po) reduziu o contorções abdominais de forma significativa. Em conclusão, o estudo demonstrou a atividades antiinflamatória e antinociceptiva do extrato aquoso em modelos experimentais. Estes resultados sugerem que o extrato aquoso D.obtusata possuem potencial terapêutico no tratamento de dor periférica e/ou de doenças inflamatórias.
