Figure 1From: Central neuropeptide Y receptors are involved in 3rd ventricular ghrelin induced alteration of colonic transit time in conscious fed ratsEffect of ghrelin injected into the 3rd ventricle (ICV) and intraperitoneally (IP) on colonic transit time. Ghrelin injected ICV as well as IP induced a dosed-related stimulation of propulsive colonic motor activity. MI = microinjection The bars represent the mean ± SEM. * P < 0.05 vs. vehicle. ■ = vehicle-group; A = 0.03 nmol ghrelin /5 μl 0.15 M saline; B = 0.3 nmol ghrelin /5 μl 0.15 M saline; C = 3 nmol ghrelin /5 μl 0.15 M saline; D = 0.3 nmol ghrelin kg-1 BW; E = 3.0 nmol ghrelin kg-1 BWBack to article page
