Fever model induced by endogenous pyrogen was used to study the effect of needling "Bai hui" point on fever. 126 rabbits served as experimental animal. The present experiment was divided into three parts: Ⅰ. Ⅱ. (injection of pyrogen)and Ⅲ. (no injection), and each part was redivided into experimental (needling "Bai hui" point or "non-channel point) and control (no needling) groups.The findings were: (1) In febrile rabbits induced by endogenous pyrogen, needling "Bai hui" points had significant febrifugal effect, i.e, inhibiting the rise of body temperature, increasing the amplitude of defervescence and accelerating the febrifugal rate. (2) In febrile rabbits, needling "non-channel points" had no marked febrifugal effect, i. e. showing the rise of body temperature, after that, accelerating the febrifugal rate. (3) On body temperature of healthy rabbits, needling "Bai hui" points hnd no hignificant effect.
