Lee SH, Heo SI, Li L, Lee MJ, Wang MH: Antioxidant and hepatoprotective activities of Cirsium setidens Nakai against CCl4-induced liver damage. Pathophysiology. 2007 Oct;14(2):71-8. Epub 2007 Jul 3.
The antioxidant activity and hepatoprotective potential of Cirsium setidens Nakai, a widely used medicinal plant, were investigated. The n-butanol (n-BuOH) fraction of leaves and roots of C. setidens had a higher 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity than the other soluble fractions. The n-BuOH fraction of roots of C. setidens had a significant hepatoprotective activity at a dose of 500 mg/kg compared to that of a standard agent. The biochemical results were confirmed by histological observations indicating that C. setidens extract decreased ballooning degeneration in response to CCl (4) treatment. The n-BuOH fraction reduced CCl (4)-induced liver injury in rats, and transcript levels of genes encoding antioxidant enzymes such as glutathione peroxidase 1 (GPO1), glutathione peroxidase 3 (GPO3) and superoxide dismutase (SOD1) were elevated in the livers of rats treated with this fraction (500 mg/kg). Based on these results, we suggest that the C. setidens extract has hepatoprotective effect related to its antioxidant activity. |
