Experimental animals were 38 cats.10% HRP 50-60μl was injected into“Tai Chong”

“QiMen”points respectively and 10 cats were used for each point.Another 18 cats were injected with10% HRP 100μl into the liver.The segmental distribution of afferent neurons of points and liverwas observed under light microscope.We observed the majority of labeled cells in the spinal gan-glion.The segmental distribution of afferent neurons of“Tai Chong”point was T_(12)

L_(1-7)andS_(1-3).The segmental distribution of afferent neurons of“Qi Men”point was T_(5-8).The segmentaldistribution of afferent neurons of liver was T_(3-12)and L(?).The results show that the afferent of“Tai Chong

Qi Men”points and the liver are mutual intersected and overlapped for 2-4 segments.The mutual intersection and overlapping were probably the morphological foundation of treatmentof liver disease by needing“Tai Chong”

“Qi Men”point

at the same time

the results may elu-cidate the underlying mechanism of correlation between aeupoints and viscera

too.
