The effect of intracerebroventricular (ICV) perfusion of bombesin (BBS) on the interdigestive migrating myoelectric complex (MMC) actvity was examined in conscious dogs with electrodes implanted on the stomach and small intestine. Cannulas and a catheter were chronically positioned in the lateral and fourth cerebral ventricles, respectively. ICV perfusion of BBS, which failed to increase plasma...
Cerebroventricular infusion of ouabain (10(-6) M) in cerebrospinal fluid produced significant increases in renal blood flow and reductions in renal vascular resistance in chloralose anesthetized, vagotomized dogs; these renal effects were not accompanied by any changes in arterial blood pressure and heart rate. Infusion of a higher concentration of ouabain (10(-5) M) enhanced significantly bloo...
The ability of neuropeptide Y to potently stimulate food intake is dependent in part upon the functioning of mu and kappa opioid receptors. The combined use of selective opioid antagonists directed against mu, delta or kappa receptors and antisense probes directed against specific exons of the MOR-1, DOR-1, KOR-1 and KOR-3/ORL-1 opioid receptor genes has been successful in characterizing the pr...
Dose-dependent analgesia was produced by microinjection of ORG 2766 into the periaqueductal gray (PAG). This analgesia was found to be potent and long-lasting and occurred at doses which were equimolar to those necessary for morphine analgesia. The same doses failed to produce analgesia by the cerebroventricular route, suggesting that the PAG was the site of action of this effect. Naloxone fail...
