摘　　要：:桂枝汤在对两种不同体温状态模型大鼠呈现解热或升温作用的同时 ,对酵母诱导的发热大鼠 ,可显著抑制其下丘脑中AC活性 ,降低异常升高的cAMP含量 ;而对安痛定诱导的低体温大鼠 ,又可显著增强其下丘脑中AC活性 ,增加异常降低的cAMP含量。实验结果提示 :桂枝汤对体温的双向调节作用可能部分是通过影响AC活性 。In febrile rats induced by fresh yeast,Guizhi decoction could cut down body temperature with weakening AC activity and descending cAMP content in hypothalamus.On the other hand,in hypothermia model induced by aminopyrine,Guizhi decoction could go up body temperature with strengthening AC activity and increasing cAMP content in hypothalamus.The results indicate that Guizhi decoction may regulate body temperature in dual direction by means of effecting AC activity and promoting or inhibiting hypothalamus intracellular metabolism of cAMP,a febrile medium in center.
