神经纤维

Objective:To observe the distribution of adrenergic fibers in adult cardiac conduction system.

目的：观察成人心脏传导系统中肾上腺素能神经纤维的分布方法：采用荧光显微镜下观察10例成人心脏传导系统中的肾上腺素能神经纤维。

NGFR positive nerve fibres were markedly reduced or absent in muscular layer and submucous layer while the hypertrophic nerve trunks in myenteric and submucosal plexuses showed a sheath of intense staining in the aganglionic colon from patients with HD.

结果 丰富的NGFR染色阳性神经纤维分布于正常结肠环肌层及粘膜下层，少量分布于纵肌层，NGFR染色阳性神经元分布于肌间神经丛及粘膜下神经丛；NGFR 染色阳性神经纤维在HD无肌间神经节细胞肠段肌层及粘膜下层内明显减少或缺如，而肌间肥大的神经干及粘膜下神经干为NGFR染色阳性，并且在其外周可见一强阳性染色带。

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.

结果显示，分类地位相近的三种甲虫脑结构大小相差悬殊：小青花金龟脑结构相对发达，蕈形体结构显著，具有发达的冠和叶，嗅叶发达；马铃薯瓢虫和榆紫叶甲的冠极度退化，嗅叶相对不发达；但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布，且反应模式相似，但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象，且在三种甲虫脑中的空间分布位置基本一致。

Methylene blue-basic magenta staining and electron microscopy Regenerating nerve were arranged in bundles in group A and B, there were minifascicle formation and a large amount of proliferated collagen in between the minifascicled, no cicatrices form, regenerating vasa spread randomly, electron microscopy show a large number of myelinated and unmyelinated fiber arranged in buddies.

亚甲基蓝-碱性品红染色及电镜观察两组均见再生神经纤维呈束状分布，有多个神经束，每一个神经束内见大量密集、粗大的有髓神经纤维，神经束之间充满增生的胶原，未见瘫痕形成，再生血管散在分布。

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。
