1.为探讨针刺镇痛效应和痛觉信息在中枢神经系的传导通路,用实验形态学方法观察了大白鼠及猫脊髓上行纤维的行程及投射点。 2.脊髓颈下部半离断后,在脑干网状结构内,可见到散在的溃变纤维和终末前溃变。其中以网状巨细胞核及网状外侧核为最多,延髓中央腹侧核、脑桥网状尾侧核及脑桥网状嘴侧核次之,而延髓中央背侧核、网状小细胞核及旁正中核则较少。 3.在中缝核群中的中缝苍白核、中缝大核以及中缝暗核和中缝脑桥核内,可见到一些溃变纤维及终末前溃变。 4.于中脑下丘底部、上丘深层以及中央灰质的外侧部,可见到一些溃变纤维及终末前滑变。 5.在丘脑,脊髓丘脑束可投射至内侧膝状体的内侧部、髓板内核中的束旁核和中央中核,以及丘脑腹后外侧核。 6.本文讨论了痛觉信息和针刺镇痛效应在中枢神经系的传导通路,以及有可能进行整合的部位。
1. To investigate the acupuncture analgesia and pain information in the central nervous system conduction pathways, using experimental morphology method observed in rats and cats spinal cord upstream fiber travel and projection point. 2. Spinal cord after the lower half of the fracture, in the brainstem reticular structure, scattered fibers can be seen and the terminal ulceration. Among them, the mesocytic giant nucleus and the reticular outer nucleus were the most, the medulla oblongata ventral nucleus, the pontine reticular caudate nucleus and the pontine reticularis lateralis nucleus were the second, while the medulla oblongata dorsalis, reticular nucleus, Nuclear less. 3. In the kapok nuclei in the pale stained nucleus, the stapes of the middle and the stapes of the stapes, the stained parenchyma, and the terminal prolapse of the stapes. In the midbrain at the base of the inferior colliculus, the superior colliculus and the lateral part of the central gray matter, we can see some of the fibers and the final slip of the ulcer. 5. In the thalamus, the spinothalamic tract can project into the medial geniculate body, the parafascicular nucleus and central nucleus in the medullary plate, and the ventromedial thalamic nucleus. 6. This article discusses the conduction pathways of pain information and acupuncture analgesia in the CNS and the potential for integration.
