Objectives:The present study was evaluated the protective roles of Spatholobi Caulis in hepatotoxic rats due to APAP overdose.
Methods:In experiments, rats were orally administrated with the aqueous extract of Spatholobi Caulis (SCE; 50, 100 mg/kg) for 4 days and then, orally gavage with APAP (1.2 g/kg) to induce acute liver damage.
Results:Oral injection of APAP caused severe hepatic injury. Plasma ALT, AST and LDH levels were significantly elevated, but SCE significantly decreased ALT, AST and LDH to the normal level. In histopathological analysis, peripheral hemorrhage around portal triads and central necrosis around central veins were founded after APAP treatment. However, these histopathological changes were recovered by SCE pretreatment. SCE also decreased the percentage of generative hepatic regions (%/mm² hepatic parenchyma), the numbers of inflammatory cells (cells/mm² hepatic parenchyma) and the number of degenerative hepatic cells (N/100 hepatic cellls) which were significantly elevated after APAP injection. Furthermore, SCE down-regulated the contents of hepatic MDA and up-regulated hepatic GSH. SCE also inhibited the decrease in the expression of pro-caspase-3 by APAP treatment.
Conclusions: Collectively, these data indicate that SCE protected APAP-induced hapatic damages through antioxidative and anti-apoptotic process. These findings the significant therapeutic potential of SCE during APAP-induced liver injury.
