RESUMO

Propedium iodide (PI) and bisbenzimide (Bb) were injected into anterior wall of the cardiac ventricle and lesser curvature of the stomach in the rat respectively. We have found that PI labelled cells are distributed in C_4-T_(12), Bb labelled cells in T_4-L_1, PI-Bb double labelled cells in T_6-T_(11) dorsal root ganglia. This result indicate that dichotomizing branches of peripheral process from some of dorsal root ganglionic neuron projecte to two visceral organs simultaneously. By means of immunocytochemistry (PAP method), some of double fluorescence cells are CGRP positive. The significance of the viscero-visceral sensory converging to same primary sensory neuron was discussed.

RESUMO

The distribution of the primary sonsory neurons from the uterus was studied in 20 female rabbits by the HRP method. The results were as follows:The HRP-labeled cells were found in all the spinal ganglia from T_9 to Co_1,but they were highly concentrated in two groups, namely L_(2~5) and S_(3~4). There were more labeled cells in the lumbar group than in the sacral group with the highest freguency in L_4 and S_3 ganglion in each group respectively. There were only a few labeled cells in L_(6~7) and S_1 spinal ganglia. The ratio of labeled cells in the thoracic and lumbar ganglia to those in the sacral and coccygeal was about 5:1.The number of labeled cells was largest following injection of HRP in the uterine cervix, smallest in the middle of the body and intermidiate in the upper and lower rogions of the uterine body. There is no difference in the distribution of labeled cell from different regions of the uterus.The majority of labeled cells were small, only a few were large ones.
