| Summary: | This study aimed to assess the impact of Moringa oleifera (M. oleifera) leaf extract against the poisoning of lead acetate; therefore, sixty mice were allocated into 4 groups with 15 in each, as G1) blank control, G2) supplied with 300 mg/kg body weight (BWT). M. oleifera extract, G3) supplied with 60 mg/kg BWT of lead acetate [Pb(C2H3O2)2], and G4) supplied with extract of M. oleifera + lead acetate. The liver enzymes were elevated post-treatment with Pb(C2H3O2)2, which then lowered to almost the normal level when M. oleifera was supplied to mice previously treated with Pb(C2H3O2)2. The values in (G3) decreased when compared with G1 (92.33 ± 12.99, 21.67 ± 2.91 and 98.00 ± 13.20 U/L, respectively. Also, the cholesterol and low-density lipoprotein levels were elevated post-supplementation with M. oleifera and Pb(C2H3O2)2. Pb(C2H3O2)2 improves the lipid profile, whereas M. oleifera pretreatment reduced cholesterol (CHOL), high density low cholesterol (HDL-c), and low-density low cholesterol (LDL-c) levels in animals fed Pb(C2H3O2)2. Pb(C2H3O2)2 elevates the total protein but lowers the total bilirubin and triglycerides post M. oleifera treatment and Pb(C2H3O2)2 when contrasted with G1. The protective effect of M. oleifera was caused by the fact that it lowered triglycerides (TG) and total bilirubin (TBIL) and raised total protein (TP). After administration of Pb(C2H3O2)2, the histological examination revealed alterations in the hepatocytes and kidneys of G3. Also, the liver and kidney cells in mice supplied with M. oleifera after Pb(C2H3O2)2 poisoning recovered. In conclusion, Pb is toxic, and the usage of M. oleifera partially enhances the negative impacts induced by Pb(C2H3O2)2.
