Resumen
Objetivo: Investigación del efecto de la suplementación nutricional con açaí en un modelo experimental de IR hepática en ratas. Métodos: Se dividieron 15 ratas macho en tres grupos: Sham: no tratadas, sin inducción de IR; IR: no tratadas, sometidas a IR hepática; AÇAÍ+IR: tratadas con extracto de açaí 500 mg/kg y sometidas a IR. El tratamiento duró 15 días. El día 16, los animales fueron sometidos a 30 minutos de isquemia y 24 horas de reperfusión. El día 17, se recogieron los hígados para analizar los niveles de sustancias reactivas al ácido tiobarbitúrico (TBARS), glutatión (GSH), ácido úrico (UA) y capacidad antioxidante equivalente a trolox mediante la inhibición de los radicales ABTS-+ (CA-ABTS) y DPPH- (CA-DPPH). Resultados: Nuestros resultados mostraron que el tratamiento con extracto de açaí disminuyó la concentración de TBARS y GSH en comparación con los grupos Sham e IR. UA aumentó significativamente en el grupo IR, pero sin cambios significativos en AÇAÍ+IR. Los niveles de CA-ABTS y CA-DPPH en el grupo AÇAÍ+IR aumentaron significativamente en comparación con los grupos Sham e IR. Conclusión: El asaí fue capaz de atenuar el estrés oxidativo y aumentar la capacidad antioxidante observada en el modelo de IR hepática, destacando su potencial para prevenir el daño tisular relacionado con la IR hepática.
