Effects of intracerebroventricular (icv) injection of ghrelin (1 nmol), 4α-PDD (10 nmol) or vehicle on cumulative water intake (a) and food intake (b) for 15–180 min after icv injection of angiotensin II (AII) (96 pmol) in conscious rats. Data for cumulative water intake and food intake are expressed as the mean ± SEM (n = 7–15). *P < 0.05 and **P < 0.01, compared with vehicle-injected rats. ^† P < 0.05 and ^†† P < 0.01, compared with 4a-PDD-injected rats
