Seasonal variations of biotransformation and antioxidant parameters in liver of the smooth flounder Liopsetta pinnifasciata from Amursky Bay (Sea of Japan)

Abstract

This study examines the seasonal dynamics of the activity of some antioxidant enzymes, the biotransformation enzyme glutathione-S-transferase, and levels of reduced glutathione and malondialdehyde in the liver of the flounder Liopsetta pinnifasciata from Amurskii Bay, Sea of Japan. The individual variability of biomarkers was fairly low. Significant sex differences were only found for superoxide dismutase.
