Objectives: Observing the changes of activity of some lysosomal enzymes in blood serum of female rabbits subjected to injection of 10 microg of ghrelin/kg of body weight.
Methods: In the blood serum the activity of cathepsins D and L, alanine aminopeptidase, acid phosphatase, lysosomal lipase and lysosomal esterase was determined.
Results: As a result of ghrelin injection the activity of all the enzymes examined in blood serum increased markedly.
Conclusion: Changes of lysosomal enzymes activities in the blood serum caused by the effects of ghrelin should be regarded as the response of the lysosomal system.
