ABSTRACT
The present study was designed to investigate the potential protective effect of Egyptian artichoke against the hepatorenal toxicity of lead in male albino rats. Twenty three compounds were identified as volatile compounds of artichoke with benzaldehyde and selinene as major constituents, 19.97% and 16.80%, respectively. Four groups of rats were used, group 1 to serve as control, group 2 intraperitoneal injected with lead acetate (20 mg/kg b.w.), group 3 lead-injected rats given artichoke head extract with drinking water (1 g/L) and group 4 lead-injected rats given artichoke leaves extract. The experiment was continued for 30 days. The plasma total protein, cholesterol, urea and creatinine were determined. Activities of each of alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (γ-GT) were determined. The level of plasma oxidation products of malondialdehyde was estimated. The histopathological changes were examined. Artichoke (leaves or head) co-treatment to the lead-administered rats attenuated the increase of ALT, AST, γ-GT activities. Also the change in cholesterol, urea, creatinine and protein levels was less marked. The values reported were near to normal. In addition, the morphological damage in the liver and kidney was reduced and the tissues appeared like those of controls. The present study suggests that, due to the presence of volatile constituents with antioxidative properties, artichoke may be useful in combating the damaging effect of lead toxicity.
