Influence of bioflavonoids on lysosomal acid hydrolases and lysosomal stability

In rats treated with (+)-catechin or 0-(beta-hydroxyethyl) rutosides, the activity of lysosomal acid hydrolase, namely, beta-glucuronidase, beta-N-acetyl glucosaminidase and cathepsin D in serum, liver and kidney and the stability of liver lysosomes was studied. The activity of these enzymes in bioflavonoids treated tissues and serum decreased significantly. Analysis of liver lysosome-rich fraction revealed an appreciable increase in the total activity and significant decrease in the rate of release of beta-glucuronidase in bioflavonoids treated animals. The results may, therefore, suggest stabilization of lysosomes due to the administration of bioflavonoids.
