Effects of eledoisin, physalaemin and some related peptides on water intake and arterial blood pressure in conscious rats

Add time:08/06/2019    Source:sciencedirect.com

SummaryThe hypotensive and antidipsogenic effects of eledoisin, physalaemin and some synthetic eledoisin- or physalaemin-like peptides were studied in conscious rats, respectively after intravenous or intracerebroventricular administration.The effects of the peptides were compared to the hypotensive or anti-dipsogenic activities of eledoisin considered equal to 100.Eledoisin and its C-terminal nonapeptide proved to be the most active antidipsogens. Conversely, physalaemin and physalaemin-like substances were poor inhibitors of water intake, but potently lowered arterial blood pressure.Apparently, there was no relationship between hypotensive and antidipsogenic effects of the substances tested.
