COMPARATIVE STUDY THE ANTIOXIDANT SYSTEM OF SEMI-AQUATIC AND TERRESTRIAL MAMMALS
<p>The aim of the work was to study the superoxide dismutase and catalase activity, tocopherol and retinol content in the tissues of the 8 diving and 6 terrestrial species of mammals. Antioxidant system status was determined in liver, kidneys, heart, lungs, spleen and skeletal muscle. The anti...
