level, and liver function enzymes activity as well as elevated levels of malondialdehyde. This
suggests oxidative stress accompanied with a significant decrease in antioxidant biomarkers
including glutathione, total antioxidant capacity, superoxide dismutase and catalase in the
examined tissues. However, the administration of GGJ could reduce these changes to control
levels. Conclusion: CGJ is a promising candidate as a free radical scavenger and antioxidant
processor in an HCC rats model. This beneficial effect was achieved by antagonizing free
radicals generation and the enhancement of the antioxidant defense mechanisms, resulting in
marked improvement of hepatic biomarkers.
