肝脏传入神经元与期门穴、太冲穴的传入神经元在脊神经节的节段及分布(辣根过氧化物酶法)

The Segmental Distribution of Afferent Neurons of Liver,and“Qi Men”point,“Tai Chong”point in the Spinal Ganglion

38只猫作为实验动物,用10%HPR50～60微升分别注入太冲、期门穴内,每个穴位各用10只猫。另18只猫则将10%HRP100微升注入肝脏内。在光镜下观察穴位及肝脏感觉神经元的节段性分布。我们在脊神经节内见到较多的标记细胞。太冲穴的传入神经元节段为胸_(12)、腰_(1～7)骶_(1～3)。期门穴传入神经元节段为胸_(5～8)。肝脏传入神经元节段为胸_(3～12)、腰_1。因此,所得结果证实太冲、期门二穴与肝脏的感觉传入神经元在脊神经节内相互重叠2～4个节段。这些重叠与交汇可认为是针灸太冲、期门穴治疗肝经病症的形态学基础。同时也证实了经穴脏腑相关的理论基础。

Experimental animals were 38 cats.10% HRP 50-60μl was injected into“Tai Chong”,“QiMen”points respectively and 10 cats were used for each point.Another 18 cats were injected with10% HRP 100μl into the liver.The segmental distribution of afferent neurons of points and liverwas observed under light microscope.We observed the majority of labeled cells in the spinal gan-glion.The segmental distribution of afferent neurons of“Tai Chong”point was T_(12),L_(1-7)andS_(1-3).The segmental distribution of afferent neurons of“Qi Men”point was T_(5-8).The segmentaldistribution of afferent neurons of liver was T_(3-12)and L(?).The results show that the afferent of“Tai Chong,Qi Men”points and the liver are mutual intersected and overlapped for 2-4 segments.The mutual intersection and overlapping were probably the morphological foundation of treatmentof liver disease by needing“Tai Chong”,“Qi Men”point,at the same time,the results may elu-cidate the underlying mechanism of correlation between aeupoints and viscera,too.
