Plasma total antioxidant (TAO) levels, LDL (low density lipoprotein), antioxidant defense potential (AOP) and the resistance to oxidation of LDL fractions were studied in chronic hemodialysis patients. The differences with respect to dialyzer membrane types before and after hemodialysis were also assessed. After isolation of LDL from plasma by precipitation, AOP was measured based on the determination of TBARS (thiobarbituric acid reactive substance), and resistance to oxidation was assessed by the metal-catalyzed peroxidation of LDL followed by the determination of the values of the peroxidation product malondialdehide (MDA) before and after peroxidation. The assay principle of TAO was based on …
