It has previously been demonstrated that oCRF and the CRF binding protein inhibitor CRF (6-33) reduce body-weight gain in obese Zucker rats. We investigated whether the reduction in body-weight is attributable to altered feeding and drinking behaviour. Obese Zucker rats were fitted with osmotic mini-pumps connected to i.c.v. cannulas. Vehicle, oCRF (5 microg/day) or CRF (6-33) (25 microg/day) were infused for 7 days and the animals observed for an additional 7 days. Body-weight and food and water-intake were recorded daily at 14.00 h. In agreement with published results, oCRF and CRF (6-33) significantly reduced body-weight gain in the obese Zucker rat. In addition, food intake was reduced, whereas water consumption was unaffected.
先前已经证明,大鼠促肾上腺皮质激素释放因子(oCRF)和促肾上腺皮质激素释放因子结合蛋白抑制剂CRF(6-33)可减少肥胖Zucker大鼠的体重增加。我们研究了体重减轻是否归因于摄食和饮水行为的改变。给肥胖Zucker大鼠安装与脑室内插管相连的渗透微型泵。注入溶媒、oCRF(5微克/天)或CRF(6-33)(25微克/天),持续7天,并对动物再观察7天。每天14:00记录体重、食物和水的摄入量。与已发表的结果一致,oCRF和CRF(6-33)显著降低了肥胖Zucker大鼠的体重增加。此外,食物摄入量减少,而水的消耗量未受影响。
