The Allium triquetrum L. Leaves Mitigated Hepatotoxicity and Nephrotoxicity Induced by Lead Acetate in Wistar Rats

The aim of this study was to scrutinize the possible mitigating role of leaves' Allium triquetrum L. against the toxicity of lead acetate on liver and kidney markers of Wistar rat. Lead acetate (Pb) and leaves' aqueous extracts (L) were orally administrated for 3 weeks. Rats were divided into the control, Pb group (500 mg/kg body weight/day), positive controls L (2g, 3g, 4g/kg BW/day), along with three combined groups of the same doses (Pb-L1, Pb-L2, Pb-L3). The levels of plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total proteins (TP), albumin (ALB), urea, creatinine (Cr), and uric acid (UA), as well as the hepatic and the renal malondialdehyde (MDA), glutathione (GSH), and glutathione peroxidase (GPx), were estimated. Results exhibited a significant increase in plasma AST, ALT, ALP, urea, creatinine, uric acid, and MDA levels of the Pb group compared to the control, with the exception of TP, ALB, GSH levels, and GPx activities that were significantly diminished, though the co-administration of garlic extracts (Pb-L) revealed a significant decrease in all mentioned markers, excluding the TP, ALB, GSH, and GPx levels. Likewise, Pb caused histological injuries in the hepatic and renal tissues of rats, while the co-administration of leaves' wild garlic has reduced such effect. Thought, the Pb-L has attenuated the Pb-induced toxicity in a dose-dependent manner. In conclusion, the aqueous extracts of A. triquetrum have the potential to alleviate Pb hepatotoxicity and nephrotoxicity through the modulation of most biomarkers in Wistar rat.
