Sažetak
The paper describes the catalytic activity of butyrylcholinesterase (BuChE) measured in plasma, liver, white adipose tissue, heart, and brain of rats intraperitoneally administered a single non-lethal dose of cycloheximide (2.0 mg/kg body weight ; CHM). The BuChE assay was performed on rats of both sexes either treated with CHM or saline (controls), and killed 2, 3, 4, 5 and 10 days later. A significant decrease of BuChE catalytic activity was observed in all tested tissues except plasma. In animals of both sexes the lowest BuChE catalytic activity was found in liver (2-6 %), while it was higher in white adipose tissue, heart, and brain. However, the respective values remained significantly different from controls (33-67%, 49-62%, and 14-71 % in males, and 24-82%, 72-86%, and 33-67 % in females). Since there was no effect of CHM on BuChE catalytic activity in plasma, the data suggest that CHM inhibits the synthesis of BuChE rather than catalytic activity of enzyme.
