N2 - Background: Based on the reported antioxidant and anti-inflammatory potential of Terminalia paniculata, the bark aqueous extract (TPW) was investigated against liver damage.Methods: Intrinsic cytotoxicity was tested on normal human liver (Chang) cell lines, followed by acute and sub-chronic toxicity studies in mice. TPW was then evaluated against CCl4-induced liver toxicity in rats. Liver enzymes (AST, ALT, and ALP) and antioxidant markers were assessed. The effect of TPW on isolated hepatic cells, post-CCl4 administration, was assessed by isolated mitochondrial membrane staining. The actions of TPW on apoptotic pathway in CCl4-treated Chang cells were also elucidated.Results: TPW was found to be safe at all doses tested in both in vitro and in vivo toxicity studies. TPW (400 mg/kg, p.o.) significantly (*p <0.05) improved liver enzyme activity as compared to CCl4. Also, it improved antioxidant status (GSH, GST, MDA and total thiol) and preserved hepatic cell architecture. TPW pre-treatment significantly attenuated the levels of phospho-p53, p53, cleaved caspase-3, phospho-Bad, Bad and cleaved PARP in CCl4-treated Chang cells, improving the viability considerably.Conclusion: The findings support a protective role for Terminalia paniculata in pathologies involving oxidative stress.
