Abstract

Heavy metals are common contaminants that have negative impacts on the body's organs and systems. Date (Phoenix dactylifera) has a great interest in biomedical applications and traditional medicine for the management of several diseases. This study evaluated the impact of Phoenix dactylifera seed extract (PDSE) on cadmium (Cd)-induced hepatotoxicity in mice. Fifty mice were equally divided into five groups, G1 was negative control, G2 was injected i.p. with PDSE (300 mg/kg b.wt) daily, G3 was injected i.p. with Cd (6.5 mg/kg b.wt) daily, G4 was injected with Cd and PDSE as in G2 and 3, respectively. G5 was injected with Cd as in G3 and then with EDTA (25 mg/kg b.wt). On day 15, sera samples were collected for biochemical parameters assessment. Liver tissues were collected for the determination of oxidants/antioxidants biomarkers and histopathological investigations. The results showed that treatment with PDSE significantly ameliorated the hepatic dysfunctions in the Cd-intoxicated mice evidenced by significant improvement in the ALT, AST, ALP, and total protein levels as well as in the total bilirubin and GGT levels. Furthermore, there was a significant increase in the SOD and CAT activities with a significant decrease in MDA levels after treatment of Cd-injected mice with PDSE. Also, treatment with PDSE resulted in improvement in the hepatic architectures alterations induced by Cd. PDSE showed promising metal chelating activities in vitro and in Cd-intoxicated mice by ameliorating biochemical and histopathological alterations in the liver tissues induced by Cd of mice.
