摘要
本研究将propedium iodide(PI)和bisbenzimide(Bb)分别注入大鼠心室前壁及胃小弯部,于C_4~T_(12)背根神经节发现PI标记细胞,在T_4~L_1背根神经节见Bb标记细胞,T_6~T_(11)背根神经节内见PI与Bb双标细胞。提示背根神经节部分细胞的周围突分支投射到内脏-内脏。免疫组织化学PAP法发现,部分PI、Bb双标细胞是降钙素基因相关肽(CGRP)免疫反应阳性。本文并对内脏-内脏感觉汇聚于同一初级感觉神经元的意义进行了讨论。
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.
