At baseline , mean ( SE ) erythrocyte SOD activity ( 2781 [ 116 ] vs 2406 [ 102 ] U/g Hb ; P < 0.05 ) and GR activity ( 5.3 [ 0.3 ] vs 3.0 [ 0.2 ] micromol nicotinamide adenine dinucleotide phosphate [ NADPH ] / min/g Hb ; P < 0.001 ) were significantly higher in children with DCM who received standard therapy compared with healthy controls.CAT activity ( 12.7 [ 0.9 ] vs 18.5 [ 1.0 ] U/g Hb ; P < 0.001 ) was significantly lower , while GSH-Px was unchanged .
