作者在1977年曾提出经络实质的二重反射假说。认为针刺效应一方面通过相应的中枢机制

可称之为长反射;另一面有可能通过外周神经末梢间的某种联系进行信息传递。一根神经的传入冲动通过侧支传出

可称之为局部短反射。这种传出冲动为能通过某种机制兴奋另一根传入神经。便可出现With regard to the nature of chennels

the authors presented the hypothesis of dual reflex in 1977.This meant that acupuncture can invoke some effects not only through CNS(long reflex)

but through the connection of peripheral nerve terminals to transmit messages(short reflex).In this experiment

30 rats were anesthetized by urethane.The superficial peroneal nerve(SPN) and the deep peroneal nerve(DPN)were found out and cut off in order to break off their connection to CNS.The sympathetic nerve which supplies to the inferior limb was found out also.The results showed that:1.With elec- trical stimulation of SPN

the action potential(AP)on the DPN was recorded at the same time.AP was induced only in a few cases(7.14%)

and with electrical stimulation of DPN

AP on SPN was none.2.With electroacu- puncture was reapplied to Zusanli aeupoint

DPN and SPN were induced

AP was recorded on DPN in 77.42% cases and on SPN in 67.74% cases respecti- vely.3.After electroacupuncture was reapplied for 30 min

we stimulated SPN with electricity.On DPN AP was recorded in 44.44% cases

while SPN was stimulated.On SPN AP was recorded in 39.29% cases(P<0.005).4.After cut off the sympathetic nerve and stimulating SPN

AP was recorded in 51.72% cases on DPN While stimulating DPN AP was recorded in 72.41% cases(P< 0.005).5.Stimulating the sympathetic nerve at the same time with stimulation of SPN

AP was induced in 25.92% cases on SPN.It suggests that impulses be transmitted between nerve terminals under certain condition and that sympathetic nerve inhibit this transmition.This might be the esseece of propagated sensation along the channels.
