In a study reported in the January 2002 American Journal of Neuroradiology, Angela Oatridge, PhD, of Hammersmith Hospital in London, and colleagues found that women's brain volume diminished by about 4 percent during pregnancy, then returned to normal after delivery.

一项在2002年一月的《美国神经放射学杂志》上发表的研究中，伦敦Hammersmith医院的Angela Oatridge博士和同事们发现，妇女的脑容量在怀孕期间会降低4%，并在分娩之后恢复原有水平。

Manganese-enhanced magnetic resonance imaging and DiI tracing will display corticospinal tract without distinction. It is valuable to trace nervous pathways by combination of two methods.

Mn(上标 2+)增强磁共振技术与DiI荧光示踪技术对皮质脊髓束的示踪效果好，二者结合应用，对临床影像学神经束路追踪研究具有较大的应用价值。

Staining and observing shows that the most pathological changes were interstitial pneumonia and hemorrhagic pneumonia, typical nonsuppurative encephalitis, and neurogangliitis et al. The lymphoid tissue was necrosis, and the amount of lymphocytes was reduced. The pathological changes of the positive cells, especially the epithelial cells were swell, denaturization and hyperplasy to the extent.

H.E。染色观察显示，病理组织学变化主要表现为间质性肺炎和出血性肺炎、典型的非化脓性脑炎、神经节炎等；淋巴结、扁桃体和脾脏等组织内淋巴细胞坏死、数目减少；有阳性反应的细胞，特别是阳性上皮细胞呈现不同程度的肿胀、变性、增生等病理变化。

The dopamine release in vivo was monitored by fast cyclic voltammetry and the concentrations of DA and its metabolites dihydroxy-phenylacetic acid and homovanillic acid were determined by high performance liquid chromatography electrochemical detection in the process study. In addition, the effects of some traditional Chinese herbs and related marine drug on behavioral changes were also evaluated in order to provide some suggestive clue for rational drug design of anti-Parkinon's disease .

许多因素都参与PD的DA能神经元的死亡，所以，本研究在制备PD动物模型的基础上，应用国内率先引进的快速周期伏安法检测设备在体动态监测DA的释放，同时应用另一种电化学检测技术—高效液相色谱电化学检测法离体检测DA及其代谢产物二羟苯乙酸和高香草酸的含量，结合行为学测定及其它方法，研究了雌激素和铁在PD发病中的作用，以及一些药物，如吲哚醌、牛磺酸、铁离子螯合剂、胆囊收缩素（CCK-8）、乌鸡白凤丸有效成份、大豆异黄酮及海洋酸性寡糖HSH971，对DA能神经元的影响，从DA能神经递质角度对PD的发病机理提供进一步的实验依据，并为PD的预防和治疗提供新的干预措施。

The creative point of this dissertation consists firstly in that monochromatic stimuli instead of combined spectral power distribution were used as visual object, and spectral luminous efficacy curves were drawn from the performance-based method; Comparison between performance-based method and brightness-matching method was then done and therefore connection between these two methods was developed; One more creative point is that the analysis based on the theory of neurophysiology and psychophysics leads to the conclusion that contribution of the colour channel during visual information processing is reflected from performance-based method, which should be considered when CIE develops the new mesopic photometry system.

论文的新颖之处在于实验中使用了单色光谱代替复合谱或物体色作为视觉目标，在分析中间视觉状态下视觉功能的光谱响应特性的基础上反推了人眼的光谱光视效率函数；论文更进一步验证了基于视觉功能法和传统的视亮度匹配法之间的联系，在两种方法之间构造了一座桥梁，为基于视觉功能法的使用初步建立了理论依据；同时论文创新地采用心理物理学的方法进行实验和结合物理学和视神经生理学的知识对实验结果进行分析，从而从视觉信息处理的神经机制层面证明了基于视觉功能法获得的结果包含了视觉颜色通道效应，并对CIE在建立新的中间视觉光度学系统时要充分考虑这一视觉颜色通道的影响提出了建议。

After a small and a middle amount samples of investigation,the 498 parents of 3 months to 1 year children were investigated with the demographic information,"0～1 year Child Nurture Environment Probative Questionnaire" and 0～4 years Child Nerve and ...

When conventional radiotherapy of nasopharyngeal carcinoma is practiced with the facio-neck field and inferior-neck-supraclavicular field by the half-beam technique, it is confirmed that the dose-overlap region at the match-plane is smaller than the whole-beam technique.

背景 近年来放射治疗剂量学研究表明，鼻咽癌应用面颈联合野与下颈切线野放射治疗时，与全束照射技术相比，半束照射技术的照射野衔接处剂量重叠区较小，理论上可能降低放射性神经损伤的发生率。

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。
