Abstract/OtherAbstract:
The neuropeptide, galanin, has been implicated in the regulation of rat growth hormone (rGH) release. In the present study, adult male rats were implanted dually with cannulae to the lateral cerebral ventricle and the right atrium. After surgical recovery, rats were infused with M-15, a specific galanin antagonist, into the lateral ventricle. During the course of this brain infusion, rats were subjected to serial blood sampling with red cell and artificial plasma replacement under stress-free conditions. Plasma was saved for rGH assay. Treatment with M-15 reduced rGH pulse amplitude and pulse frequency when compared to vehicle-infused controls. These data suggest that brain galanin participates in the ongoing stimulation of pulsatile rGH release in the adult male rat.
