The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

给药局部肉眼观察未见明显的纤维组织增生；HE染色可见B、C、D三组给药后四周及八周时硬膜内外均有炎细胞浸润，纤维细胞轻度增生，硬膜外神经根内有炎细胞浸润及炎性渗出；特殊染色B、C、D三组同A组相比未见有脊髓及神经根的改变；免疫组化染色，给药后四周及八周时，硬膜内外均有Ⅱ型胶原纤维增生；固兰染色B、C、D三组未见有明显脱髓鞘改变，与A组相比无明显异常改变；电镜观察B、C、D三组在给药后的四周及八周时，表现为硬膜外神经根内髓鞘厚薄不一，形状不规则，可见成纤维细胞，神经内膜中可见有巨噬细胞；粗大的有髓神经纤维变化明显，无髓神经纤维受累较轻；八周时电镜下D组改变较B、C两组为轻。

During the relatively refractory period a neuron may be stimulated to fire, given increased stimulation. Neurons are capable of representing differences in input only through rate of response. Myelinted fibers conduct the wave of depolarization more rapidly than demyelinated fibers, primarily due to saltatory conduction.

在相对反抝期一条神经可能会被刺激过度，特定增加的刺激，神经单位是足以表现在输入的差异性，仅透过反应的比率，有髓的纤维引导去极波比脱髓鞘纤维更加快速，主要是由於跳跃性的传导。

Unmyelinated nerve fibers dominated in number in each nerve tract although there were both myelinated and unmyevinated nerve fibers there. Schwann's cells were related to the development and structure of the two fiber types.

鸡INR被神经束膜分隔成许多神经束，束内既有无髓纤维又有有髓纤维，但以无髓神经纤维的数量占绝对优势。

RESULTS: Chitin tubes containing NGF successfully induced the nerve regeneration, regularly arranged myelinated and unmyelinated axons could be observed across the 8 mm gaps, and the myelin sheath was thick with clear lamellar structure at 8 weeks after operation, The regenerated nerve fibers increased and were more mature at 16 weeks after operation.

结果 实验侧术后8周，再生神经中有髓和无髓神经纤维排列整齐，有髓神经的髓鞘厚，板层结构清晰；术后16周，再生神经中有髓和无髓神经纤维数量增加，形态接近正常神经。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

结果：轻度牵拉组牵拉侧前角个别神经元稍肿胀，神经元及神经纤维形态基本上正常，个别白质小片状脱髓鞘样改变，神经根髓鞘和轴索轻度水肿，脱髓鞘不明显；中度牵拉组白质有脱髓鞘改变，神经纤维排列紊乱，轴索崩解、断裂；灰质神经元水肿明显加重，前角运动神经原细胞尼氏体消失，核固缩、深染，神经根髓鞘和轴索水肿，局部轻度脱髓鞘改变；重度牵拉组牵拉侧白质为不规则的大片脱髓鞘区，前角运动神经元胞体固缩、变形、核深染，神经根有髓神经纤维萎缩、数目减少，重度脱髓鞘改变。

Any of various stiff marsh plants of the genus Juncus, having pliant hollow or pithy stems and small flowers with scalelike perianths.

After HRP application to the rostral area (n=10), quite a number of labelled cells were distributed at the ventrolateral part of the nucleus of trapezoid body, the lateroventral periolivary nucleus and the retrotrapezoid nucleus. After HRP application to the caudal area (n=10), HRP labelled cells were mainly located at the lateral reticular nucleus and the ventral part of at the lateral paragigantocellular nucleus LPGi. After HRP application to the intermediate area (n=6), only 8HRP labelled cells were observed at the in 6rats. After HRP application to the control area (n=4), only 6HRP labelled cells were found at the rostral ventrolateral reticular nucleus.

大鼠延髓腹外侧表面的头端化学感受区表面敷贴辣根过氧化物酶后，在延髓斜方体核、外周橄榄腹外侧核和斜方体后核均有HRP标记细胞存在；于尾端化学感受区表面敷贴HRP后，在延髓的巨细胞旁外侧核、外侧网状核和舌下神经核有HRP标记细胞存在；于中间区表面敷贴HRP后，在6只大鼠的延髓内部区域仅观察到8个HRP标记细胞；于对照区敷贴HRP后，在4只大鼠的延髓内部区域仅观察到6个HRP标记细胞，散在地分布在头端腹外侧网状核。

MAIN OUTCOME MEASURES: The density and size frequency distribution of sciatic nerve medullated fibers, as well as the number, the maximum diameter and the mean diameter of medullated fibers in two group of 0la rats and 6J rats.

主要观察指标：两组中O1a鼠和6J鼠坐骨神经的有髓纤维密度、有髓纤维数目、有髓纤维最大直径、有髓纤维平均直径。
