OBJECTIVES: Changes in the activity of beta-glucuronidase, N-acetyl-beta-glucosaminidase, cathepsin D and L, alanine aminopeptidase and lysosomal acid lipase in lysosomal fractions of the liver and kidneys of mice, which were administered 20 mg/kg b.w. of exogenous melatonin (N-acetyl-5-methoxytryptamine) for 7 and 14 days were investigated. METHODS: The slices of the liver and kidney were homogenized in 0.1M phosphate buffer, pH 7.0. Homogenates were subjected to differentiated centrifuging and determination of studied enzymes. RESULTS: Melatonin caused lowering of the activity of all the investigated lysosomal enzymes in the liver and kidney. CONCLUSION: Administration of melatonin was caused the lowering of the activity of the investigated lysosomal enzymes in comparison with values in control groups.
