Résumé
The present investigation was designed to valuate the antiangiogenic efficacy of some local medicinal plants against liver cancer induced by diethylnitrosamine [DEN] methanolic extracts of cupressus sempervirens, chelidonium majus and tropaeolum majus were used in this study. Vascular endothelial growth factor [VEGF], alpha-Feto-protein [AFP], ferritin, alanine transaminase [ALT], aspartate transaminase [AST], Alkaline phosphatase [ALP], superoxide dismutase [SOD] and Glutathione peroxidase [GPx] were determined in blood while Nitric oxide [NO] was determined in liver tissue homogenate. Furthermore histopathological investigations ere done. The results showed that the treatment with methanolic extracts of all selected plants led to a significant reduction in the level of all the desired biochemical parameters, while the administration of cupressus sempervirens only improved the histopathological pictures of liver architecture. These results suggest a beneficial effect of these plant extracts against experimentally-induced hepatocellular carcinoma and the possible mechanism of the protective effects may be partly due to the antioxidant activity of these plants
