[Factors in rat liver cytosol, inhibiting chemiluminescence during nonenzymatic lipid peroxidation].
The effect of normal rat liver cytosol on the level of Fe/ADP-ascorbate-induced lipid peroxidation in the total particulate fraction (mitochondria plus microsomes) has been studied. The intensity of lipid peroxidation was measured using the chemiluminescence technique and by malonic dialdehyde (MDA) production. Dialyzed cytosol significantly decreased the level of chemiluminescence and, to a much lesser extent, the rate of MDA production. Gel filtration on a Sephadex G-200 column led to the appearance of at least three cytosolic fractions which suppressed the low-level chemiluminescence. These fractions differed from one another by their molecular masses, kinetics of chemiluminescence inhibition and effects on the intensity of MDA production. The putative functional role of antioxidative defence factors from rat liver cytosol is discussed.
