Antioxidant ntioxidant system in fox hybrids (<i>Alopex-Vulpes</i>)
The systems of generation and neutralization of reactive oxygen species (ROS) were evaluated in liver, kidney and heart of silver fox (<i>Vulpes vulpes L</i>.), blue fox (<i>Alopex lagopus L</i>.) and fox hybrid -bluefrost (<i>Alopex-Vulpes</i>). It was revealed that functioning of both ROS generation and neutralization systems are tissue and species specific. Cluster analysis showed the similarity of bluefr neutralization systems was discussed.
