The dynamics of contents of the total protein, haemocyanin and activity of the antioxidant enzymes under condition of acute hyperthermia in pulmonate mollusk Lymnaea stagnalis

The dynamics of total protein’s and hemocyanin’s content in the hemolymph, as well as the activity of the antioxidant enzymes (peroxidase, catalase and glutathione S-transferase) in pulmonate mollusc Lymnaea stagnalis (Linnaeus, 1758) under the impact of acute temperature stress were evaluated. It has been shown that the effect of acute thermal stress (30 °C) leads to activation of physiological mechanisms of stress resistance and has no influence on activity of the antioxidant enzymes in investigated population of molluscs.
