Abstract
Neuromedin S (NMS) is recognized as an anorexigenic peptide in the brain of mammals. In chicks (Gallus gallus), however, the effect of NMS has not been investigated. Therefore, the purpose of the present study was to investigate whether intracerebroventricular (ICV) injection of NMS affected feeding and drinking behavior in chicks. The injection of NMS (0.01-1Â nmol) significantly decreased food intake under both ad libitum and food deprivation-induced feeding conditions. However, NMS did not affect water deprivation-induced drinking behavior. ICV injection of NMS stimulated voluntary locomotion and wing-flapping behavior. In addition, we found that those effects of NMS might be related to the hypothalamus-pituitary-adrenal axis because ICV injection of NMS stimulated corticosterone release. The present study suggests that central NMS functions an anorexigenic factor in chicks.
