| 摘 要： | 用~3H]-2-脱氧葡萄糖相对定量的方法进一步证明了痛信息主要投射到同侧脊髓背角的Ⅰ、Ⅱ、Ⅳ,Ⅴ、Ⅵ和Ⅹ层,针刺信息投射到同侧背角的Ⅰ、Ⅱ、Ⅳ、Ⅴ层,两者有相互重叠的层次投射,正是在这些部位,两种信息可能相互作用、在脊髓水平实现对痛觉的调制作用。

| Abstract: | The relative quantitative ~3H]-2-deoxyglucose (2DG)method was used to study the laminary projection of acupuncture and noxious information in the rat spinal cord dorsal horn. The noxious information projected to lamina Ⅰ、Ⅱ、Ⅳ、Ⅴ、Ⅵ and Ⅹ, and the acupuncture information projected to lamina Ⅰ、Ⅱ、Ⅳ and Ⅴ in the spinal cord dorsal horn. The noxious and acupuncture information had overlapping projection areas in the spinal cord. It is in such areas that the two types of information may be interacted on each other and consequently the nociception is modulated at the spinal level. |
