Activity of some lysosomal enzymes in plasma and leucocytes of rabbits exposed to effect of retinol and hydrocortisone.

Observing activity of some lysosomal enzymes in blood serum and leucocytes of rabbits subjected to injection of 200,000 units of retinol and 25 mg of hydrocortisone/kg of body weight it was found that: 1. In the effect of retinol administration there was an increase in the activity AP, BGAL, BGLU, AspAT and lipase in blood serum after 72 hours and NAGL after 168 hours while in leucocytes BGAL and NAGL after 72 hours and AGAL after 168 hours. 2. As a result of hydrocortisone injection the activity of all the enzymes examined (except Ala-Na) in blood serum increased markedly already after 24-48 hours. 3. In leucocytes hydrocortisone caused a significant increase in the activity of AP, BGRD, NAGL, BGAL, AGAL and cathepsin D. 4. The glucose level in blood plasma decreased after 48 hours and 120 hours after hydrocortisone injection and 168 hours after retinol injection.
