| 摘 要： | 目的：观察桂枝汤对发热和低体温模型大鼠下丘脑中腺苷酸环化酶（AC）和磷酸二酯酶（PDE）活性的影响。方法：采用放射性同位素方法测定模型动物下丘脑中AC及PDE活性。结果：在酵母诱导发热模型大鼠中，桂枝汤可使下丘脑中AC活性明显降低（P＜0．05）；而在安痛定诱导的低体温模型大鼠中，它可使AC活性明显增强（P＜0．05）。在两种模型中，桂枝汤对PDE活性的影响均不明显。结论：桂枝汤对体温的双向调节作用可能是部分通过影响AC活性来实现的。

| Abstract: | Objective: To observe the effect of Guizhi Decoction (GZD) on adenyl cyclase (AC) and phosphodiesterase (PDE) activities in hypothalamus of rat models of fever and hypothermia. Methods: The AC and PDE activities in hypothalamus were determined using radio isotope method. Results: GZD could lower the AC activity in yeast induced fever rat model (P<0 05), but cause rise of AC activity in aminopyrine induced hypothermia model (P<0 05). No significant influence of GZD on PDE activity was shown in both fever or hypothermia models. Conclusion: The bi directional thermo regulation effect of GZD might be partially due to influence on AC activity. |
