Figure 4: Serum protein carbonyl content (nmol/mg protein) in control, Ajwa extract alone and in combination with lead acetate-treated rabbits. Results are expressed as means ± SD. of ten rabbits per group, Ajwa extract group I-significantly different from control group P<0.05 II-significantly different from a lead alone treatment group P<0.05. III-significantly different from lead and Ajwa extract group P<0.05.
