title: Anorexia following the systemic injection of amylin.
abstract: The intravenous injection of 100 micrograms/kg of rat amylin reduced food intake in schedule-fed rats for 1 h of an 8 h measurement period. Associated with this brief anorexia was a hyperglycemic response, observed 30 min after a subsequent amylin administration. Determination of neurochemical alterations revealed increased concentration of serotonin in the hypothalamus and decreased level of the dopamine metabolite, 3-methoxytyramine, in the corpus striatum. Since similar neurochemical alterations were observed following the systemic injection of glucose, both the neurochemical changes and anorexia following intravenous amylin treatment may be secondary to hyperglycemia.
