title: [Influence of delta-sleep-inducing peptide on the activity of proteolytic enzymes in the rat brain under hypokinesia].
abstract: Single administration of the delta-sleep-inducing peptide (DSIP) in a dose of 12 micrograms/100 g to intact animals makes the activity of neutral proteinases and cathepsin D higher in the rat brain and blood serum. Hypokinesia of different duration changes activity of neutral and acidic proteinases and induces accessibility of cathepsin D to the cytosol as a result of damage in lysosomal membrane. Injection DSIP induces a decrease A/B of cathepsin D to the control level under 1-h hypokinesia condition and normalizes the neutral proteolytic activity under 6-h hypokinesia condition.
