中脑

The top of neural tube forms basic encenphalic shape,namely endbrain, interbrain, midbrain and afterbrain. The abnormal closure of neural tube will result in neural tube detects. Encephalocoele is a common congenital malformation whose mechanism was no known. NO participates in the physiologic process of brain.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

Anencephaly, the single most common open neural tube defect, is characterized by the absence of the cerebral hemispheres and the lack of bony calarium aboe the orbits Fig.

无脑畸形，最常见的单一的开放性神经管缺损，其特点是无大脑半球且没有眼眶以上的骨性颅盖（图10-37A-B和图10-37C）。胎儿有正常的中脑和后颅窝，但大脑半球未正常发育。

The rats demonstrating an average of at least 280 complete contralateral turns/ 40 min for 4 times in response to apomorphine were selected as PD ra...

结果：发现6-OHDA注入大鼠右侧中脑黑质后，大鼠向损毁对侧的旋转次数明显增加(大于280圈/40min)，PD模型成功率为50.5%。

Methods Turning tests induced by apomorphine and forelimb functional tests were performed. Also, the expression of TH mRNA in mesencephalon of the rats was detected by semi-quantitative analysis of one step RT-PCR.

利用阿朴吗啡诱发旋转试验和前肢功能试验，检测PD大鼠的神经行为学特点，一管法逆转录聚合酶链反应半定量检测其中脑TH mRNA的表达。

They also show Fos activation and phasic spiking increases in response to a variety of aversive stimuli (including footshock, cues that predict footshock and reward omission), and firing decreases in response to appetitive stimuli.

本研究表明，在最近所鉴定的GABA能的RMTg中主要用于接收LHb输入的神经元对中脑多巴胺神经元具有强烈的表达，并在后抑刺激（足部电击、休克的预测信号、食物剥夺或奖赏缺失）后出现短暂性活化和/或Fos诱导和在奖赏或预测的奖赏刺激后出现抑制。

Objective:To compare the difference of fMRI between visual and auditory memory.

目的 ：研究视觉和听觉记忆过程中脑功能fMRI的差异。

Birth defect in which the forebrain and/or midbrain are diminished in size or are missing.

无脑出生缺陷里前脑和中脑在大小上是减少了或者是遗失掉了。

Results MRI of all WE patients showed symmetrical high signals on the brain T2WI, Flair and diffusion weighted imaging, 6 cases of them in the medial thalamus, 4 cases in surrounding the aqueduct, 3 cases in the third ventricle gray matter, 2 cases in the mamillary bodies, 1 case in the putamen,1 case in the optic chiasm, 1 case in the superior cerebella vermis and 1 case in the subcortical white matter; 2 cases had reinforcement effect. 2 cases showed no abnormal signals on T2WI and Flair early, but showed high signal symmetrically in the medial thalamus on DWI imaging.

结果 8例WE患者MRI示脑部T2WI、Flair成像及弥散加权成像有对称性异常高信号影，其中出现在丘脑内侧6例、中脑导水管周围灰质4例、第三脑室周围灰质3例、乳头体2例及壳核、视交叉、小脑上蚓部、皮质下白质各1例；2例有增强效应。2例发病早期T2WI、Flair无异常信号影，DWI示丘脑内侧对称性异常高信号影。

Methods The activity of urine NAG isoenzyme, NAG/Cr and blood NAG isoenzyme in 47 patients with acute CVD (15 patients with brain hemorrhage and 32 patients with brain infarction) were examined by p-nitrobenzene chronometry.

采用对硝基酚比色法，分别测定了47例急性脑血管疾病患者（其中脑出血15例，脑梗死32例）的尿液NAG同工酶谱、尿NAG与尿肌酐的比值、血清NAG活力。

Objective To evaluate relationship between urine NAG isoenzyme and acute cerebrovascular disease. Methods The activity of urine NAG isoenzyme, NAG/Cr and blood NAG isoenzyme in 47 patients with acute CVD (15 patients with brain hemorrhage and 32 patients with brain infarction) were examined by p-nitrobenzene chronometry.

目的 探讨尿液N-乙酰-β-D-氨基葡萄糖苷同工酶与急性脑血管病的关系方法采用对硝基酚比色法，分别测定了47例急性脑血管疾病患者（其中脑出血15例，脑梗死32例）的尿液NAG同工酶谱、尿NAG与尿肌酐的比值、血清NAG活力。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
