神经分布

14Th week after injury, the reorganization of labelled neurons' distribution was found in the autograft group, but only one case in the NTN/PGLA group. Conclusion Local application of PGLA tube with neurturin can recover the axoplasm flow of regenerated nerve fibers, its long-term effect can match that of the nerve autograft, and collateral axonal branching occurred less.

应用NTN/PGLA导管的修复能够和自体神经移植修复一样恢复神经缺损的连续性和逆行轴浆运输功能，后期效果相当；应用NTN/PGLA导管修复后神经元分布异位明显少于自体神经移植修复，提示较少发生轴突误向再生，减少面肌联带运动的发生。

因此，本研究提出一个具有自组织能力之阶层式小脑模型类神经网路，它可以依据分析学习样本的分布，自动建立网路的记忆体配置，并藉由阶层式的学习架构，来有效降低记忆体的需求，使其具有解决高维度问题的能力，而此类神经网路架构亦具有可扩充性，可以在不影响其他网路的学习架构下，任意的增减输出节点的个数，此外，我们也提出了一个渐进式学习的演算法来训练此一类神经网路。

The fine vessel braneh could be found on epineurium and periheurium in 3 days, the capillary network has been formed in the midportion of the nerve segment and spread toward two sides in 7 days, from 14 to 21 days, the capillary network spreaded through the whole grafts and conrected with the capillaries from the two ends.

术后3天，血管已在神经外膜和束膜上形成微小分支。7天移植神经的中段已形成毛细血第四军医大学硕士研究生毕业论文管网，并向两端扩展，而自两端长入的血管则较少。14天至刀天，血管网己分布在移植神经段的全段及各层，并与两端长入的毛细血管相吻合。

Results In both groups after injury, several changes on oculomotor nerve occurred including number reduction of neurons, dispersion in distribution, disappearance of sub-nuclear structure, structure destruction of fibers and myelin sheath, neurite gemmation, and specificity decrease in fibers distribution, while all these changes in section-suture group were more obvious.

结果 不同损伤均可导致神经元的数量减少，分布散乱，亚核分布结构改变，神经纤维和髓鞘的结构破坏，轴突芽生及再生纤维分布的特异性降低，而且上述改变在神经切断组更加明显。

The distribution characteristics of primary neurons in skin referral area and gastric mucosa are that spinal ganglions present segmental distribution and superposing with each other,moreover,sympathetic ganglions present diffused distribution and have no segmental distribution,which may be the neural basis of treating visceral pain by intracutaneous- injection drug.

结论胃痛的皮肤牵涉区与胃黏膜初级神经元分布的特点是在脊神经节呈节段性分布且相互重叠，在交感神经节呈弥散性分布，无节段性分布，也相互重叠，这可能是皮内注药治疗内脏痛的神经基础。

METHODS: The spiral modiolar artery in guinea pig cochlea was exposed by microsurgery, then the fluorogold or horseradish peroxidase was given around the SMA for retrograde tracing.

Results There was a similar distributive pattern of Neul, PPCA and β-gal in the inner ear. Neul intense staining was observed in the cochlear spiral ganglion cells, spiral limbus, spiral ligament, vestibular ganglion cells, cristae, maculae hair cells, and weak staining in inner hair cells, outer hair cells, supplying cells of the organ of Corti and stria vascularis. The intense staining of PPCA and β-gal were observed in the spiral ganglion and vestibular ganglion cells, and weak staining in the spiral limbus, spiral ligament, stria vascularis and organ of Corti. The inner ear exhibited no staining when Neul, PPCA and β-gal were deficient, respectively.

Neul最强的染色主要在螺旋神经节细胞、螺旋韧带、螺旋缘、前庭神经节细胞及壶腹嵴、球囊和椭园囊感觉毛细胞，较弱的染色分布于血管纹和Corti器内、外毛细胞及支持细胞；PPCA和β-gal在螺旋神经节和前庭神经节细胞有较强的染色，血管纹、螺旋韧带、螺旋缘和Corti器内、外毛细胞及支持细胞呈较弱的染色反应；各自酶缺乏时内耳免疫染色消失。
