Possible mechanisms responsible for hepatic lysosomal fragility in hypercholesterolemic rats have been investigated. It was found that certain factor(s) present in the intracellular environment of liver were required for the release of lysosomal enzymes. Elevated hepatic dehydroascorbic acid content in hypercholesterolemic rats is thought to render the lysosomes fragile in this pathological state, since this compound was found to labilise the lysosomes in vitro. Quercetin and hesperidin were found to be responsible for lysosomal stability, probably by reducing the content of dehydroascorbic acid to a normal level in the hypercholesterolemic condition.
