摘要：

Studies were carried out to determine the effect of rat liver cytosolic protein enriched in fatty acid binding protein on the microsomal and mitochondrial ascorbate-Fe++ lipid peroxidation and to determine how vitamin A influences the inhibitory effect of this protein in the peroxidation process. The inhibition of light emission (maximal induced chemiluminescence) by the fatty acid binding protein containing fraction was protein concentration dependent. The inhibition of chemiluminescence produced by the addition of cytosolic protein on rat liver microsomes or mitochondria was more evident when the soluble protein obtained from the vitamin A treated group was used. The results indicated that vitamin A plays a role in protecting rat liver microsomes and mitochondria against the harmful effect of lipid peroxidation.
