Resumo

Introdução: No processo de cicatrização de feridas é importante o papel de mediadores pró-inflamatórios como o fator necrótico tumoral (TNF-α) e a interleucina-1. O TNF-α é um mediador pró-inflamatório produzido pelos macrófagos que estimula as células inflamatórias, os fibroblastos e as células epiteliais. Uma das plantas herbáceas indicadas para tratamento é o quiabo (A. esculentus) por possuir propriedades benéficas que incluem antidiabetes, antioxidantes e propriedades antibacterianas e anti-inflamatórias.
Objectivo: O objectivo da investigação é conhecer o efeito do extracto etanólico de A. esculentus na expressão do tnf-α na cicatrização de feridas de ratos Wistar diabéticos.
Metodologia: Desenho de investigação experimental laboratorial com controlo apenas pós-teste, utilizando ratos Wistar brancos machos (Rattus norvegicus) como amostra de 30. O tratamento consistiu em controlo negativo (K-), controlo positivo (K+), experiências com várias doses de dose P1 de 300 mg/kgBB, dose P2 de 600 mg/kgBB e dose P3 de 900 mg/kgBB de etanol extra de quiabo. No dia 21, foi recolhido sangue através da veia retro-orbital para examinar os níveis de TNF-alfa pelo método de ensaio imunoenzimático (ELISA) utilizando uma ferramenta manual de ELISA da Bioeureaux.
Resultados e discussão: Os resultados da medição da expressão de TNF-α mostraram que a expressão de TNF-α no grupo controlo positivo teve uma expressão média de 6,95 ± 0,33 e diminuiu 174,35% em comparação com o controlo negativo (K-), com uma expressão média de 19,06 ± 0,29.
Conclusões: Existe diferença estatisticamente significativa nos grupos Quiabo P1, P2 e P3. A administração do quiabo em etanol pode reduzir significativamente a expressão do fator de necrose tumoral α (TNF-α) no tecido da ferida de ratos Wistar modelo de Diabetes Mellitus.
