ABSTRACT
The effects of Carica papaya leaf (CPL) aqueous extract on alcohol induced acute gastric damage and the immediate blood oxidative stress level were studied in rats. The results showed that gastric ulcer index was significantly reduced in rats pretreated with CPL extract as compared with alcohol treated controls. The in vitro studies using 2,2-Diphenyl-1-Picryl-Hydrazyl (DPPH) assay showed strong antioxidant nature of CPL extract. Biochemical analysis indicated that the acute alcohol induced damage is reflected in the alterations of blood oxidative indices and CPL extract offered some protection with reduction in plasma lipid peroxidation level and increased erythrocyte glutathione peroxidase activity. Carica papaya leaf may potentially serve as a good therapeutic agent for protection against gastric ulcer and oxidative stress.
RESUMEN
Los efectos de; extracto acuoso de la hoja de Carica papaya (CPL) en el daño gástrico agudo inducido por alcohol y el nivel de estrés oxidativo inmediato en la sangre, fueron estudiados en ratas. Los resultados mostraron que el índice de úlcera gástrica se reducía significativamente en ratas pre-tratadas con extracto de CPL, en comparación con los controles tratados con alcohol. Los estudios in vitro mediante el ensayo con 2,2-difenil-1-picrihidrazilo) mostraron la fuerte naturaleza antioxidante de extracto de CPL. El análisis bioquímico indicó que el daño agudo inducido por alcohol se refleja en las alteraciones de los índices oxidativos de la sangre y el extracto de CPL ofreció cierta protección con la reducción del nivel de peroxidación lipídica del plasma y el aumento de la actividad de la glutatión peroxidasa de los eritrocitos. La hoja de la Carica papaya puede servir potencialmente como un buen agente terapéutico para la protección contra la úlcera gástrica y el estrés oxidativo.
