Fig. 5. Levels of TBARS and the activities of superoxide-dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) in the liver of control rats (T), rats consuming ginger (G), rats treated for 7 and 5 days (P₁ and P₂, respectively) and rats pretreated with ginger for 6 weeks (P₁G and P₂G). Values correspond to the mean of 6 measurements ± SD. Student test: **(p ≤ 0.01) indicates significant differences between (P₁ and P₂) and control rats (T). ⁺⁺(p ≤ 0.01) indicates significant difference between (P₁G and P₂G) and (P₁ and P₂) rats.
