Thymoquinone, the Nigella sativa Bioactive Compound, Prevents Circulatory Oxidative Stress Caused by 1,2-Dimethylhydrazine in Erythrocyte during Colon Postinitiation Carcinogenesis

Figure 2

Erythrocyte SOD activity in adult rats of controls or treated with DMH, TQ, and different (TQ + DMH) treatments. Values are means ± SE for five rats in each group. DMH, TQ, and different (TQ + DMH) groups versus control group: ^∗𝑃<0.05; ^∗∗𝑃<0.01; ^∗∗∗𝑃<0.001, (TQ + DMH) groups versus DMH: ⁺𝑃<0.05; ⁺⁺𝑃<0.01; ⁺⁺⁺𝑃<0.001. U: Enzyme required for 50% inhibition of NBT reduction.
