Ghrelin-induced gastric emptying is impaired in AP-ablated mice. (a) Representative images of thionin staining of the DVC of AP-intact and AP-ablated animals. Scale bars, 100 μm. (b and c) Bar graphs representing the 2-hour food intake and the percentage of gastric emptying, respectively, in AP-intact or AP-ablated mice treated with either vehicle or ghrelin. Data represent the mean ± SEM. ^aP < 0.05 vs vehicle groups.
