Abstract
  1. The effects of CRF9-41 delta helical on morphine withdrawal signs in rats were studied. 2. Intracerebroventricular administration of CRF9-41 delta helical 5 at 10 micrograms/kg reduced central and peripheral symptoms of the withdrawal syndrome, such as ptosis, jumping, wet dog shakes and teeth chattering; other signs remained unchanged. The effect were not dose dependent. 3. The hypothermi characteristic of the Withdrawal syndrome was reduced by CRF9-41 delta helical. 4. These results suggest that the hypothalamo pituitary adrenal(HPA) axis play an important role in the morphine withdrawal syndrome in rats.
摘要
  1. 研究了CRF9 - 41δ螺旋对大鼠吗啡戒断症状的影响。2. 脑室内注射10微克/千克的CRF9 - 41δ螺旋可减轻戒断综合征的中枢和外周症状,如眼睑下垂、跳跃、湿狗样抖动和牙齿打颤;其他症状保持不变。该作用不依赖剂量。3. CRF9 - 41δ螺旋减轻了戒断综合征的体温过低特征。4. 这些结果表明,下丘脑 - 垂体 - 肾上腺(HPA)轴在大鼠吗啡戒断综合征中起重要作用。
