摘　　要：实验选用成年家兔9只,将2%CB-HRP5微升注入“人中”穴区,其中4只事先切断一侧眶下神经。未切断神经者,双侧半月神经节有标记神经元,双侧三叉神经脊束核、三叉神经感觉主核和延髓网状结构有标记终支;切断一侧眶下神经者,只对侧有标记;无论切断眶下神经与否,双侧面神经核均有标记细胞。对其投射的功能意义也作了讨论。CB-HRP was injected into 'Renzhong' (Du 26) of the rabbits and the lebeled cells or terminal arborizations were examined in the trigeminal ganglions of both side, cervical spinal cord, and brain stem. In the rabbits with intact infraorbital nerves, the labeled cells were found in the trigeminal ganglions of both side. The labeled terminal arborizations were bilaterally found in the spinal trigeminal nuclei, the main sensory trigeminal nuclei, and the reticular formation of medulla oblongata. In the rabbits with section of one infraorbital nerve, the positive results existed only in the structures of the opposite side to the sectioned nerve. The labeled cells were also found in the bilateral facial nuclei of either preperation.
