Objective To investigate the effect of lead acetate on the growth of cultured hippocampal neural cells and expression of nNOS.

目的 研究不同剂量醋酸铅对原代培养的海马神经细胞生长和神经元型一氧化氮合酶表达的影响。

These drugs are designed to increase levels of acetylcholine, a chemical that enhances communication between nerve cells in the brain.

这些药物的目的是增加各级乙酰胆碱的一种化学品，加强沟通，神经细胞在大脑中。

Increased release of acetylcholine from the neurons, leading to heightened activity in cholinergic pathways throughout your brain.

从神经细胞里释放的乙酰胆碱增加，引发遍布你大脑的胆碱能通路活动的提高。

MSCs were cultured in soft agar for 2 weeks to observe the clone growth.

结果 MSC在相应的诱导条件下可以向骨、脂肪和神经细胞分化。

Result: The scores of motor functions in rehabilitative training group were significantly better than those in control group on the 7th d, 21st d and 35th d (P.05). Under microscope and electron microscope the nerve-cells of cortical infarct marginal zone in rehabilitative training group showed more integrity nuclear membranes, less agglutinative chromatin, clearer structures of mitochondria and more plentiful ribosomes on rough endoplasmic reticulum compared with that in control group.

结果：在造模后第7天、21天、35天时卒中训练组大鼠的平衡木及网屏测试评分分值均优于卒中对照组(P.05)；且于光镜、电镜观察下脑皮质梗死边缘区神经细胞的核膜较卒中对照组完整、核下凝集的染色质较为稀少，线粒体结构较为清晰，粗面内质网表面核糖体更为丰富。

The researchers injected a substance into the retina to eliminate ganglion cells (a type of nerve cell found near the surface of the retina) and amacrine cells.

研究人员注入了实质内容纳入消除视网膜神经节细胞（一种神经细胞附近发现表面的视网膜）和无长突细胞。

Nervous tissue stands in an intimate relationship to other tissue anatomically contiguous to it.

神经细胞和其他的很自然且连续在一起的细胞组织有很密切的关系。

CGRP content in myocardium gradually enhanced from normal group to controls group, and model group's was the highest. We found immunopositive neurons and nerve fibers of nNOS and CGRP by immunochemistry in normal myocardium. They were mainly round-shaped and oval-shaped, also tadpole-shaped、 shuttle-shaped、triangle-shaped、ring-shaped and irregular-shaped. Nv of neurons and nerve fibers in atria were more than in ventricle in some degree; Those in right part of heart were more than in left. Morphology of CGRP neurons changed in model group, the number of ring-shaped neurons increasing, while the round-shaped and oval-shaped decreasing, and Nv and Sv of model group were markedly less than normal. Expression of nNOS mRNA was overly higher than normal group, but CGRP was opposite.

心肌组织CGRP的含量由正常组、实验对照组至CHF组逐渐升高，差异显著；免疫组化研究表明心肌组织中存在nNOS和CGRP免疫阳性神经细胞及纤维，细胞形态多样，正常多以圆形和椭圆形为主，还有梭形、蝌蚪形、三角形、指环形及不规则形，细胞密度心房高于心室，右心高于左心；CHF组CGRP神经细胞形态有一定改变，淡染的指环形细胞增多，而深染圆形或椭圆形细胞减少，其面、数密度均明显低于正常组，差异显著；用RT-PCR测得CHF组nNOS mRNA极度表达，显著高于正常组，而CGRP表达明显低于正常组。

In this study, we observed the ultrastructural changes of cerebral infarctions.

本文还观察了脑缺血的超微结构改变，并证实缺血边缘区的神经细胞和内皮细胞损伤与缺血时间呈不一致性，缺血24小时在边缘区也可见形态较完整的神经细胞。

The cell membrane appears three layered,and the cytoplasm inclusions of neuron consist of Nissl body,Golgi body,endoplasmic reticulum and m...

神经细胞的数量与附肢的生理活动强弱有一定的关系。神经细胞数量多，附肢活动力强，反之则弱。

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。
