摘　　要：Ｐ物质受体在人延髓和脊髓后角内的分布丁玉强郑恒兴龚良维吕岩熊抗辉秦秉志李继硕（第四军医大学解剖学教研室，梁琚脑研究中心，西安７１００３２）Ｐ物质（ＳＰ）被认为是一种与外周伤害性刺激传递密切相关的一种神经活性物质［１］。近年来，ＳＰ的受体（ｓｕｂｓｔ...The distribution of substance P receptor (SPR) was immunohistochemically investigated in the huaman medullary and spinal dorsal horns. SPR like immunoreativity (LI) was mainly located in the neuronal cell bodies and dendrities, and the majority of the SPR positive neurons exhibited Golgi like staining outline. The distribution pattern in the medullary spinal dorsal horns was similar to each other. The SPR positive neurons wre distributed mainly in lamina I, sparsely in the deeper laminae. The present results suggested that the SPR positive neurons in the human medullary and spinal dorsal horns, especially in lamina I, may accept nociceptive information from periphery through substance P.
