ABSTRACT

ABSTRACT BACKGROUND: Indigofera suffruticosa Mill (Fabaceae) is abundant in northeastern Brazil and popularly used in the treatment of infectious and inflammatory processes. Several biological properties, such as anti-inflammatory, anticancer, antitumor, hepatoprotective and low toxicity, are reported for this plant. OBJECTIVE: This study investigated hepatoprotective activity and the antioxidant effect of methanolic extract of I. suffruticosa leaves (MEIS) on Swiss albino mice submitted to experimental models of acetaminophen-induced liver injury. METHODS: MEIS (50 mg/kg; p.o.) was standardized according to the LD50 and its hepatoprotective property on Swiss albino mice evaluated during a 7-day period. On the eighth day, the acetaminophen-induced hepatic injury was performed. Histomorphometric analysis of liver tissue, antioxidant activity and serum levels of alanine aminotransferase (AST), aspartate aminotransferase (ALT) and bilirubin were measured. RESULTS: MEIS (50 mg/kg; p.o.) restored serum enzyme levels and results were close to those of positive control (silymarin) when compared to the negative control. Histopathological and histomorphometric analyzes confirmed MEIS hepatoprotective activity, showing reorganization of structural units of cells, nuclei and sinusoidal capillaries of hepatocytes, reducing the damage on liver tissue and increasing organ regeneration rate. MEIS showed high antioxidant potential at concentrations of 1000 and 500 µg/mL. CONCLUSION: This study suggests that MEIS has hepatoprotective activity and high antioxidant potential.


RESUMO CONTEXTO: Indigofera suffruticosa Mill (Fabaceae) é abundante no nordeste do Brasil e popularmente utilizada no tratamento de processos infecciosos e inflamatórios. Várias propriedades biológicas, como anti-inflamatório, anticâncer, antitumoral, hepatoprotetor e baixa toxicidade, são relatadas para esta planta. OBJETIVO: Este estudo investigou a atividade hepatoprotetora e o efeito antioxidante do extrato metanólico de folhas de I. suffruticosa (MEIS) em camundongos albinos suíços submetidos a modelos experimentais de lesão hepática induzida por paracetamol. MÉTODOS: O MEIS na dose de 50 mg/kg (via oral) foi padronizado de acordo com a LD50 e sua propriedade hepatoprotetora em camundongos albinos Swiss avaliados durante um período de sete dias. No oitavo dia, a lesão hepática foi induzida por paracetamol em todos grupos pre-tratados. Foram medidos os níveis sericos enzimaticos, alanina aminotransferase, aspartato aminotransferase e bilirrubina, análise histomorfométrica do tecido hepático e atividade antioxidante. RESULTADOS: O MEIS restaurou os níveis séricos de enzimas e os resultados foram próximos aos do controle positivo (silimarina) quando comparados ao controle negativo. As análises histopatológicas e histomorfométricas confirmaram a atividade hepatoprotetora do MEIS, mostrando reorganização das unidades estruturais das células, núcleos e capilares sinusoidais dos hepatócitos, reduzindo os danos no tecido hepático e aumentando a taxa de regeneração de órgãos. O MEIS apresentou alto potencial antioxidante nas concentrações de 1000 e 500 µg/mL. CONCLUSÃO: Este estudo sugere que I. suffruticosa tem atividade hepatoprotetora e alto potencial antioxidante.

ABSTRACT

Indigofera suffruticosa is a plant generally used to treat infectious and inflammatory processes. This work aims to evaluate the histopathological changes in the liver tissue of mice with Sarcoma 180 after subchronic treatment with aqueous extract obtained by infusion and maceration of Indigofera suffruticosa leaves. Male mice were divided into four groups of six animals: G1, G2 and G3 patients with Sarcoma 180 and Sarcoma 180 G4 without sarcoma. G1 and G2 were treated with infusion mashing respectively (50 mg/kg ip); G3 and G4 controls received saline (15 ml/kg ip). The histopathological and morphometric analysis of liver tissue after subchronic treatment with aqueous extracts by infusion and maceration of the groups G1, G2 and G4 were similar and showed no degraded areas or leukocyte infiltration compared to G3, which shows a marked destruction of liver architecture. The results showed that after subchronic treatment with the aqueous extract of leaves Indigofera Suffruticosa obtained by infusion and maceration, the hepatic architecture was preserved, suggesting its use as an alternative hepatoprotective agent.


Indigofera suffruticosa es una planta utilizada para tratar procesos infecciosos e inflamatorios. Este trabajo tiene como objetivo evaluar los cambios histopatológicos en el tejido del hígado de ratones con sarcoma 180 después del tratamiento subcrónica con el extracto acuoso obtenido por infusión y maceración de las hojas de Indigofera suffruticosa. Los ratones machos fueron divididos en cuatro grupos de seis animales: pacientes G1 , G2 y G3 con Sarcoma 180 y G4 sin Sarcoma. G1 y G2 fueron tratados con infusión de maceración respectivamente (50mg/kg.ip); Controles G3 y G4 recibieron solución salina (15 ml/kg.ip). El análisis histopatológico y morfométrico de tejido hepático después de un tratamiento subcrónico con extractos acuosos por infusión y la maceración de los grupos G1, G2 y G4 fueron similares y no mostraron áreas degradadas o la infiltración de leucocitos en comparación a G3, que muestra una marcada destrucción de la arquitectura del hígado. Los resultados mostraron que después de un tratamiento subcrónico con el extracto acuoso de hojas de Indigofera suffruticosa obtenidos por infusión y la maceración, se conservó la arquitectura hepática, lo que sugiere su uso como una alternativa de agente hepatoprotector.
