Plasma antioxidant capacity and oxidant damage in normo and hyperuricemic patients on hemodialysis.

	Normouricemic Patients (n = 26)	Hyperuricemic Patients (n = 67)	p
DPPH● scavenging (mM TE)	1.0495 ± 0.1226	1.1385 ± 0.1681	0.007
ORAC (μM TE)	2337.8 ± 370.7	2441.7 ± 313.7	0.213
MDA (nmol/mL)	12.7 ± 4.6	0.6 ± 13.5	0.020

DPPH^●—2,2-diphenyl-1-picrylhidrazyl radical; ORAC—oxygen radical absorbance capacity; MDA—malondialdehyde; TE—Trolox equivalents. DPPH^● scavenging and ORAC assays were made by duplicate and MDA determination was made once. Results are expressed as mean ± SD. p < 0.05 was considered statistically significant.
