The in vivo evaluation of oxidative stress (DNA fragmentation, membrane lipoperoxidation and carbonyl protein formation) and the antioxidant defenses (concentration of reduced glutathione, as well as catalase and glutathione S-transferase activities) were measured in mice pre-treated with EAF (10, 30 or 100 mg/kg, orally) and later exposed to carbon tetrachloride (CCl (4)).

Glutathione S-transferases (GSTs) play a key role in cellular detoxification of environmental toxicants through their conjugation to glutathione (GSH).
Since the hepatotoxicity of carbon tetrachloride (CCl (4)) has been suggested to be due to the generation of free radicals leading to membrane LPO, the present studies were designed to compare hepatotoxicity of CCl (4) in GSTA4-4 null (-/-) and wild type (+/+) mice.

As the polyphenols are thought to protect cell constituents against oxidative damage through scavenging of free radicals, the present work was undertaken to evaluate the effects of polyphenols extracted from bees wax on the oxidative stress induced by carbon tetrachloride (CCl4) in rats.
The results showed a significant decrease in hepatic antioxidant enzyme activities viz. catalase, glucose-6-phosphate dehydrogenase (G-6-PDH), glutathione peroxidase (GSH-Px), glutathione reductase, superoxide dismutase (SOD) and a significant increase in glutathione S-transferase (GST) and gamma-glutamyl transpeptidase (GGT) by CCl4, probably due to the peroxidative effects.
