Megjegyzések:	Pituitary adenylate cyclase activating polypeptide (PACAP) is a pleiotropic neuropeptide exerting diverse actions in the central and peripheral nervous systems. A few studies indicate that PACAP is involved in the regulation of feeding and water homeostasis. The aim of the present study was to investigate changes in PACAP38 concentrations in diVerent brain areas following food or water deprivation in male and female rats. Rats were sacriWced 12, 36 and 84 h after water or food removal. PACAP levels were determined by radioimmunoassay. Our results show that levels of PACAP decreased in the hypothalamus in both sexes after water deprivation, with a more marked, signiWcant decrease in females at 12 h. A decrease was observed also in the telencephalon, with a similar pattern in both genders: levels were lowest after 12 h, and showed a gradual increase at the other two time-points. PACAP levels increased in the brainstem of male rats, while females had a decrease 12 h after water deprivation. The pattern of changes in PACAP levels was very diVerent after food deprivation. In male rats, PACAP levels showed a signiWcant increase in the hypothalamus, telencephalon and brainstem 12 h after the beginning of starvation. In females, a less marked increase was observed only in the hypothalamus while no changes were found in the other brain areas. Our results show a sensitive reaction in changes of endogenous PACAP levels to water and food deprivation in most brain areas, but they are diVerentially regulated in male and female rats.
