摘要
辣根过氧化物酶类(CB-HRP)逆行跨神经节追踪观察证明,脊髓脑干胶状质内可能存在一条与体表胃经相对应的神经网络链。计算机仿真证明,在一定条件下,单、多穴交联的脊髓脑干神经网络链模型均可产生具有循经感传基本特征的冲动传递;在相同条件下,单交联较多交联易产生上述的冲动传递。在刺激家兔解溪穴诱发节段性脊髓场电位的模型上,督脉注射士的宁,93.33%实验例可在T12或C7记录到传导性脊髓场电位,传导波以P2N3为主。此电位可能与感传的发生有密切关系。
The segmental distribution and projected region of primary afferent fibers of acupoints of the Stomach Channel in Substantia Gelatinosa of spinal cord and lower brain stem were examined by CB-HRP technique in rabbits. The results suggest that there could be a chain of neural netwrks corresponding to the Stomach Channel in Substantia Gelatinosa of spinal cord and brain stem.Mathematical models of nearest neighbor coupling and multiple coupling chains of neural networks in spinal cord and brain stem were input to computer in computer language, The results indicate that impulse transmission possessing the basic characteristics of propagated sensation along the meridian might be generated in the nearest neighbor coupled system and the multiple coupled system and this kind of impulse transmission be generated much more easily in the nearest neighbor coupled system than in the multiple coupled system on the same terms.Propagated field potentials in spinal cord were recorded at level T12 and C7 in 28 out of 30 rabbits (93.33%), when Strychnine (2 mg/1 cc/a rabbit) was injected into the acupoints of Du channel at level T11 and L1 on condition that the segmental field potentials in spinal cord were evoked by stimulation at point Jiexi in the rabbits. Propagated waves are mainly P2 and N3. It was found that the PSC could be evoked after intecting Strychnine into the acupoints of Du channel on human beings.
