a
Data are expressed as the means ± SD.
b
Based on histological grade, tumors were subdivided into group I (well, well-moderately and moderately differentiated) and group II (moderately-poorly and poorly differentiated).
T-AOC, total antioxidant capacity; SOD, superoxide dismutase; HBV, hepatitis B virus; TNM, Tumor-Node-Metastasis.
