HRP was injected into one side of the cervical vagus nerves in 30 adult rats. The HRP-labelled cells were seen bilaterally in the dorsal nucli of the vagus nerve, nuclei suprespinalis, nuclei dorsomedialis and ipsilaterally in nucleus ambiguus, nucleus retrofacialis, nucleus retroambiguulis, spinal nucleus of the accessory nerve, nucleus intercalaus and nucleus hypoglossalis.The caudal ends of dorsal nucleus of the vagus nerve of both sides were combined each other and formed a "Commissural part".The volume of the HRP-labelled cell bodies of the dorsel nucleus of the vagus nerve and nucleus ambiguus was measured. There are three types of HRP-labelled cells in the dorsal nucleus of the vagus nerve(4646.9±295. 0μm~3, 1943.2±702. 1μm~3, 721.9±163.1μm~3) and two in the nucleus ambiguus 8048.6±3987.1μm~3, 3073.9±579.9μm~3).

30只大白鼠,一侧颈迷走神经干内注射HRP后,在两侧迷走神经背核、脊上核、背内侧核和同侧疑核、面神经后核、后疑核、副神经脊髓核、闰核及舌下神经核出现HRP逆行标记神经元。两侧迷走神经背核的尾部相互合并,构成迷走神经背核联合部。对迷走神经背核和疑核的标记神经元胞体作了测量。迷走神经背核内三类不同大小的标记神经元,它们的近似体积分别为:4646.9±29.50;1943.2±702.1;721.9±163.7立方微米。在疑核内有两类不同大小的标记神经元,它们的近似体积为:8048.6±3987.1;3073.9±579.9立方微米。

WGA--HRP solution was injected into the rostral half of the red nucleus of 10 cats and the labeled projection fibers to the trigeminal sensory nuclear complex were traced anterogradely. The result was that in all parts of the contralateral trigeminal sensory complex descending fibers from the red nucleus were observed, which, according to our previous study, arised from the parvocellular portion of the rostral 2/3 of the red nucleus. The labeled terminal branches in the subnucleus caudalis of the trigeminal...

WGA--HRP solution was injected into the rostral half of the red nucleus of 10 cats and the labeled projection fibers to the trigeminal sensory nuclear complex were traced anterogradely. The result was that in all parts of the contralateral trigeminal sensory complex descending fibers from the red nucleus were observed, which, according to our previous study, arised from the parvocellular portion of the rostral 2/3 of the red nucleus. The labeled terminal branches in the subnucleus caudalis of the trigeminal spinal nucleus were distributed in its deeper part, corresponding to Laminae Ⅲ-Ⅵ of the spinal dorsal horn, with higher concentration in Lamina V. The authors support the view that this area, adjacent to the subnucleus caudalis, receiving primary afferent terminals and having sensory neurons, especially pain neurons, which pro- ject to the thalamus, is more proper to be taken as a part of the subnucleus caudalis than as a part of the reticular formation. Projection fibers from the red nucleus must come into contact with one or more of the structures here, including the primary afferents, the secondary sensory neurons, or interneurons, so that the descending impulses from the red nucleus might converge with the primary afferent inputs and play certain role of modulation on the transmission of oro--facial sensations,especially pain.

将WGA—HRP溶液注入于猫红核吻侧段,顺行追踪了红核向三叉神经感觉核簇投射的纤维行径及终未分布,发现红核有下行纤维投射于对侧三叉神经感觉核簇各亚核。结合作者等既往的研究肯定此投射的起源为对侧红核吻侧2/3段小细胞部背外侧的中、小型细胞群。投射终末以尾侧亚核的深层相当于脊髓背角Ⅳ、Ⅴ、Ⅵ层的地区最为密集,特别是V层最为集中。鉴于此区又是三叉神经初级传入纤维的投射区,还有三叉神经二级感觉(特别是痛觉)神经元胞体及树突的存在,因而作者等认为此区应属于尾侧亚核的一个部分,而不应将之归属于网状结构。红核向此区的投射可能和三叉初级传入纤维之间或两者与二级感觉神经元之间有汇聚的关系。这种汇聚可能对口面部的感觉特别是痛觉的传递产生某种调节作用。

0.05~0.2μl of HRP (Sigma Ⅵ) were introduced into the periaqueduetal gray (PAG) of 45 rats at the superior collicular level, each brain was sectioned and processed with DAB, BDHC, O-D and TMB reactions. 29 were chosen for analysis and according to the locations of the injection center and the extent of reaction, were divided into 3 groups:1. The injection center was found in the lateral part of PAG; the reaction only involved a small area within PAG (11 rats), labeled cells were seen in PAG, tectum, reticular formation (RF) and dorsal raphe nucleus.2. The injection center was in the dorsolateral part of PAG; the reaction area extended out of PAG to the nearby RF and tectum (9 rats); labeled cells were seen in the structures mentioned in group 1 as well as in habenular nucleus (hn), parafascicular nucleus (PFN), hypothalamic nuclei (anterior, posterior, ventromedial, dorsomedial, lateral), thalamic nuclei (lateral, reticular, medial part of ventral nucleus), paraventricular gray (PVG), nucleus of the optic tract, nucleus of posterior commissure (NPC), parabigeminal nucleus (PBN), locus ceruleus, ventral nucleus of lateral geniculate body, entopeduncular nucleus.3. The injection center was in the lateral or ventrolateral part of PAG, the reaction area extended to the nearby RF, tegmentum and part of tectum (9 rats), labeled cells were seen in the structures mentioned in group 1 as well as in substantia nigra, H_1, H_2, zona inserta, HN, PFN, PVG, NPC, PBN, locus ceruleus, pretectral area and nuclei of hypothalamus. In this group 3 rats were processed with TMB reaction. Labeled cells were seen not only in the above-mentioned structures but also in the deep layers of anterior cingulate cortex (areas 23 and 24), nucleus raphe magnus, nucleus reticularis gigantocellularis, periventricular gray of 4th ventricle, dentate nucleus of cerebellum, lamina Ⅴ~Ⅶ of cervical spinal cord (the other segments were left out), preoptic and supraoptic nuclei, suprachiasmatic nucleus, anterior nucleus of mammillary body, medial nucleus of amygdaloid nucleus, spinal nucleus of nerve Ⅴ. The labelled cells were seen chiefly in the ipsilateral side. Neuronal connections also were analysed according to the disparity in labelled structures.
