Abstract

It is well known that central injection of bombesin (BN) suppresses feeding in mammalian and avian species, but the anorexigenic effect of central BNare still open with special reference to the chick. The dose response (0, 0.1 and 0.5 mug) of intracerebroventricular (ICV) injection of BN was examined in Experiment 1. ICV injection of BN inhibited food intake in a dose-dependent manner. Experiment 2 was done to determine whether BN interacts with the orexigenic effect of neuropeptide Y (NPY) in the neonatal chick. Central administration of NPY (2.5 mug) greatly enhanced food intake, but co-injection of BN (0.5 mug) suppressed food intake. The dose response of NPY (2.5 mug) co-injected with three levels of BN (0, 0.1 and 0.5 Gig) was examined in Experiment 3. ICV injection of BN attenuated the hyperphagia by NPY in a dose-related fashion. It is suggested that central BN may interact withNPY for the regulation of feeding in the neonatal chick.
