Gastrointestinal (GI) motility and gut hormones have been considered to be involved in the development and maintenance of obesity. Our aim was to assess the relationships between gastric emptying (GE), GI transit and gut hormones and leptin concentrations in diet-induced obese rat model. Male 6-week-old Sprague-Dawley rats were fed with a high-fat (HF) diet for 8weeks to generate diet-induced obesity (DIO) and diet resistant (DR) rats. GE, GI transit and plasma ghrelin, cholecystokinin (CCK), PYY and leptin concentrations were determined in DIO, DR and control (CON) rats. The DIO rats had slower GE, higher plasma leptin and CCK concentrations, and lower plasma ghrelin concentration compared with CON and DR rats. GE was correlated with plasma ghrelin (r=0.402, P=0.028), CCK (r=-0.518, P=0.003) and leptin concentration (r=-0.514, P=0.004). The slower GE, which can be considered as an adaptive response aimed at HF diet induced obesity, may be mediated by changes of plasma ghrelin, CCK and leptin concentrations. |
