Objectives: To evaluate the possible relationship between aminotransferases levels and markers of oxidative stress in chronic hepatitis C patients.
Design And Methods: Patients without treatment for hepatitis were divided in to group I (15-39 U/L); group II (41-76 U/L) and group III (81-311 U/L) of activity alanine aminotransferase (ALT). Blood markers of oxidative stress [catalase (CAT), glutathione peroxidase (GPx), thiobarbituric acid-reactive species (TBARS), nonprotein and protein thiol (NP-SH and P-SH) groups and vitamin C] were determined.
