Fig. 1From: Role of ghrelin in the pancreatic exocrine secretion via mitogen-activated protein kinase signaling in ratsConcentration of plasma ghrelin (a) and cholecystokinin (CCK) (b) in rat exposure to exogenous ghrelin (0, 0.1, 1.0 and 10.0 μg/kg BW). The values are expressed as the average with SEM (n = 4). Asterisk shows significant difference with the ghrelin-untreated group (*p < 0.05, **p < 0.01)Back to article page
