Fig. 4From: Centrally administered ghrelin potently inhibits water intake induced by angiotensin II and hypovolemia in ratsCumulative water intake (a) and food intake (b) for 15–180 min after intracerebroventricular (icv) injection of ghrelin (1 nmol), 4α-PDD (10 nmol), or vehicle in hypovolemia rats induced by ip injection of polyethylene glycol (PEG). Data for cumulative water intake and food intake are expressed as the mean ± SEM (n = 6–8). *P < 0.05 and **P < 0.01, compared with vehicle-injected rats. † P < 0.05 and †† P < 0.01, compared with 4a-PDD-injected ratsBack to article page
