结果发现，手术侧备用根初级传入纤维在脊髓后角Ⅱ板层内的侧支出芽和突触重建明显加快，起到代偿因切除大部分背根造成靶神经元在结构上和功能上去神经支配的作用［2］。

The intact secretory granules (100 -300 nm) coated with membrane existed not only in the endings of the unmyelinated nerve fibers but also occasionally in perivascular space.

The correlation between ICJ mucosal MC counts and the number of SP positive fibers was found ( r =0.646 7, P .01), and MCs were close to SP positive fibers in lamina propria, which were demonstrated as unmyelinated nerves.

广泛分布于肠道黏膜和黏膜下层的肥大细胞(mastcell，MC)很有可能是这一机制中的一个中心环节，因为MC参与肠黏膜的免疫调节，受炎症刺激激化后，可分泌多种介质，如组胺、5 羟色胺、细胞介素

The results of the study suggest that a selectiveand long-lasting sciatic nerve block (up to 2 wk) can be providedby RTX without any significant damage to the unmyelinated nervefibers.

结果：研究结果说明 RTX 可以提供选择性长时效坐骨神经阻滞（最长2周），对无髓鞘神经纤维没有明显损害。

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。

In this paper, we first analyze the mechanism of action potential propagated alongan unmyelinated fiber, and present a hypothesis that the velocity of transmembranecurrent is the equivalent of the propagation velocity of action potential. Then usingthe H-H model and the cable equation we obtain the formula of the velocity. Insuccession, we apply a similar method to analyze the mechanism of action potentialpropagated along a myelinated fiber. Using the McNeal model and the CRRSS model,we obtain the formula of the velocity.

接下来，应用与无髓鞘神经纤维相类似的方法，分析了动作电位在有髓鞘神经纤维上的传递机制，同样得出了可用跨膜电流的移动速度来等效动作电位传递速度的结论，利用 McNeal 模型和 CRRSS 模型，建立了有髓神经纤维在兴奋传递期间等效电路模型，并推导出了速度的计算模型。

Recently, many foreign researchers found that the tetrodotoxin-resistant voltage-gated sodium channel, Nav1.8, which is expressed only by unmyelinated small-diameter sensory neurons associated with nociception in dorsal root ganglion and trigeminal ganglion, is involved in pain pathways and play a key role. Thus it provides a new idea in pain research.

近年来，国外众多学者发现河豚毒素(tetrodotoxin，TTX)不敏感型(TTX-resistant，TTX-R)电压门控钠通道Na_v1.8与疼痛的关系极为密切，其仅分布在背根神经节(dorsal root ganglion，DRG)和三叉神经节(trigeminal ganglion，TG)中的与伤害性感受密切相关的无髓鞘的小直径感觉神经元胞体上，它为疼痛的研究提供了新的思路。

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。

It is thought that there's an independent neural pathway through which itch is transferred mainly by peripheral unmyelinated C fibers to the most superficial part of dorsal horn, then the lamina Ⅰ spinothalamic tract ascends to the thalami and further projects to the cortex.

目前认为存在独立的痒觉神经传导通路，主要由外周无髓C纤维传入信号至脊髓背侧角的最浅层，Lamina Ⅰ脊髓丘脑束上行至丘脑，进一步投射至皮质区。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
