[The segmental distribution of the afferent neurons of the "zusanli" point and the caecum in rabbits--a study with the horseradish peroxidase method].
Ten adult rabbits were used in this experiment. A solution of 10-20% HRP (sigma IX, RZ = 3.2) was injected into the "Zusanli" point and the subserosa of the caecum. The uptake and retrograde transmission of HRP in the afferent neurons of both the somatic and visceral nerves were traced to the spinal ganglia. The results showed that: 1. Labelled afferent neurons from the region of "Zusanli" point were found in the spinal ganglia T12-S2 with a higher concentration in L4-S2. 2. Labelled afferent neurons from the region of the caecum were found in the spinal ganglia T2-S2 with a higher concentration in T12-L2. 3. The ranges of distribution of labelled afferent neurons from the regions overlapped in the segments T12-S2.
