Popis: Rats with genetic susceptibility to catalepsy (GC strain) were compared with Wistar rats (W). After an intraperitoneal administration of 120 micrograms/100 g delta sleep-inducing peptide (DSIP) in GC rats the duration of cataleptic freezing was shortened (13.8 +/- 9.5 sec against 27.2 +/- 7.5 sec in control). MAO-B activity decreased due to DSIP administration both in GC and W rats. It is hypothesized that the DSIP effect MAO-B in GC rats may correct the lost MAO-A function in deamination of dopamine, a common MAO-A and MAO-B substrate, and the dopaminergic neurotransmission in catalepsy.
