| 摘 要： | 目的：研究纳洛酮对白细胞介素-1β（IL-1β）致热大鼠发热反应的影响及机制。方法：经大鼠侧脑室微量注射IL-1β建立发热模型,观察纳洛酮对发热大鼠体温的影响,并测定下丘脑中环磷酸腺苷（cAMP）和腹中膈区精氨酸加压素（AVP）含量。结果：纳洛酮减弱了IL-1β致热效应,同时下丘脑中cAMP和腹中膈区AVP含量也相应减少（P〈0．01）。结论：纳洛酮能够抑制大鼠IL-1β性发热,其机制可能是抑制下丘脑中cAMP的合成,并且促进腹中膈区AVP的释放。

| Abstract: | Aim： To study the effects and mechanism of naloxone on the febrile response in IL-1β-indueed fever rats. Methods： The fever model was established by intracerebroventricular injection of IL-1β in rats. The effect of naloxone on the body temperature of fever rats was observed. The contents of cAMP in hypothalamus and AVP in VSA were detected. Results： Naloxone alleviated IL-1β-induced fever and the contents of cAMP in hypothalamus and AVP in VSA were correspondingly decreased（ P 〈 0.01 ）. Conclusion： Naloxone could inhibit IL-1β-induced fever in rats, and the mechanism might be due to inhibiting synthesis of cAMP in hypothalamus and promoting release of AVP in VSA. |
