BACKGROUND Magnesium (Mg), selinium (Se), zinc (Zn), manganese (Mn), and copper (Cu) are involved in the mechanisms of antioxidant defense. Mn and Cu, which participate in the generation of reactive oxygen species (ROS), also have pro-oxidative properties. OBJECTIVES To evaluate the levels of Mg, Se, Zn, Mn, and Cu, as well as the effectiveness of antioxidant defense mechanisms in children wi...

It is known that free radicals, their products and reactive oxygen species (ROS) are associated with many diseases. The study focuses on both some changes in oxidative stress factors patients acute appendicitis (AA) the of GST PON1 enzyme activities metabolism. This involved control group (n = 31) 52). In groups, which play an important role metabolism were determined. There activity between gr...
