胼胝体上的

Several cases of congenital agenesis of the corpus callosum have been reported in the literature, and it is clear that this deformity need not result in language learning difficulties.

据文献上的报导，有几个先天胼胝体发育不全的案例，而这种缺陷对导致语言学习的困难不是必要的。

Results Statistical analyses revealed that FA values were decreased in the anterior cingulum of schizophrenia subjects.

结果 重复测量方差分析表明，部分各项异性值只是在精神分裂症患者的扣带束前部与正常人有统计学上的显著性差异，其他部位：额叶，颞叶，顶叶，枕叶，胼胝体膝部和压部，内囊前肢和后肢未见统计学上的显著差异。

The MBP content of telencephalon tissue in control rats were 78~82 礸/ml, there were no difference in all the 2 Gy irradiated, 1 week and 1 month after 10 to 30 Gy irradiated groups.

髓鞘染色显示30 Gy照射后6月大鼠在胼胝体区有较典型的脱髓鞘病变存在。10~30 Gy照射后1~6个月各组在超微结构上也有不同程度的髓鞘异常。

objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

Spikelets 1.3–1.8(–2.2) mm, olive green, occasionally violet tinged; glumes narrowly lanceolate-oblong, lower glume usually slightly longer than upper, sometimes equal, keeled, keel scabrid to aculeate, apex subacute; callus glabrous or nearly so; lemma 3/4–9/10 spikelet length, awnless, apex obtuse; palea 0.3–0.6 mm,(1/4–)1/3(–1/2) lemma length.

小穗1.3-1.8(-2.2)毫米，绿色的橄榄，偶有，紫色微染；颖片狭披针形长圆形，上面的稍长于的通常下部颖片，等长的有时，龙骨状，龙骨状对具皮刺，近尖的先端粗糙；胼胝体无毛或近无毛；外稃3/4-9/10个小穗长度，awnless，先端钝； 0.3-0.6毫米的内稃，(1/4-)1/3(-1/2)外稃长度。

In agenesis of the corpus callosum, the caum septum pellucidum is absent, and the third entricle is eleated between the laterally displaced frontal horns.

在胼胝体发育不全中，透明隔腔缺失，第三脑室上抬介于向侧方移位的两前角之间。

The corpus callosum is not isible in the standard transerse iews of the brain but agenesis of the corpus callosum may be suspected by the absence of the caum septum pellucidum and the 'teardrop' configuration of the lateral entricles (enlargement of the posterior horns).

诊断：正常在脑的标准横切面上看不到胼胝体，通常通过透明隔腔小时和侧脑室的泪滴状改变怀疑有胼胝体的发育不良，确诊胼胝体发育不良需要在正中冠状面和正中矢状面上，一般需要做阴道B超显示。

RESULTS: There was reduced fractional anisotropy in patients with schizophrenia in regions corresponding to the superior longitudinal fasciculi bilaterally and in the genu of the corpus callosum.

结果：分裂症患者的双侧上纵束和胼胝体膝部的FA值降低。

However, significant differences in ADC in different diffusion gradients were found within normal human brain parenchyma, which including caudate nucleus, lentiform nucleus, centrum semiovale, posterior limb of internal capsule, and corpus callosum, except the thalamus.

而除丘脑外的正常脑灰质团块及白质（半卵圆中心、内囊后肢、胼胝体膝部和压部）的ADC值在不同扩散梯度方向上存在显著性差异（P≤0.05）。

Objective Based on findings in exploration of the rules of plastic changes in MI and SmI of adult rats following total brachial plexus root avulsion injuries, we investigated the central mechanism of transhemispheric reorganization primarily after contralateral seventh cervical nerve root transfer.

目的： 在探讨成年大鼠全臂丛根性撕脱伤后初级体感运动皮层可塑性变化规律的基础上，初步探讨健侧颈7移位正中神经术后跨大脑两半球功能重组的中枢机制，明确胼胝体在该重组过程中所起的作用。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
