Delta sleep-inducing peptide in spontaneously hypertensive rats. 1986

M V Graf, and A J Kastin, and G A Schoenenberger

Delta sleep-inducing peptide has been shown to exert extra-sleep effects as well as effects on sleep. In this study, the concentrations of DSIP-like immunoreactivity were measured by radioimmunoassay in the plasma of spontaneously hypertensive rats (SHR). They were found to be about 25% higher in SHR plasma than in the plasma of the normotensive Wistar-Kyoto (WK) controls. DSIP was then infused for 10 days by osmotic minipump (200 micrograms/kg/day) into SHR. This resulted in in maintenance of BP at a level of about 200 mm Hg as compared with the significant increase to about 220 mm Hg after 10 days in the SHR controls infused with 0.9% NaCl. After daily SC injection of a single dose of 200 micrograms/kg DSIP for each of 5 days in SHR, findings were similar. The results raise the possibility of an involvement of DSIP in the regulation of BP in SHR.

D003701 Delta Sleep-Inducing Peptide A nonapeptide that is found in neurons, peripheral organs, and plasma. This neuropeptide induces mainly delta sleep in mammals. In addition to sleep, the peptide has been observed to affect electrophysiological activity, neurotransmitter levels in the brain, circadian and locomotor patterns, hormonal levels, psychological performance, and the activity of neuropharmacological drugs including their withdrawal.
