[An index to the antioxidant activity of biological materials].

Abstract

A new method for measuring serum and tissue antioxidative activity is based on a relationship between accumulation of lipid peroxidation (LPO) products in incubation medium and the amount of the substrate during LPO activation. The ratio of malonic dialdehyde accumulation during LPO activation in two samples of different volumes is proposed as an index of antioxidative activity.
