The activity of Cre recombinase is predominantly detected in the midbrain, diencephalon and olfactory bulb in the SCC4.4-iCre transgenic brain. However, it only can be observed in the caudal part of the midbrain in the SCC2.7-iCre brains. The results suggest that CYP11A1 gene expression could be differentially regulated in different regions of the brain.

结果发现，4.4 kb与2.7 kb之CYP11A1启动子皆可使Cre重组酶表现於胚胎脑部，前者主要表现在中脑、间脑及嗅球，后者仅主要表现在中脑尾端，说明了CYP11A1在不同脑区表现所需的元素有所不同，可能有不同的调控机制。

Raphe nucleus has been described as a midline structure located in the midline region and adjacent reticular formations of the brainstem and mesencephalon.

中缝核群是位于延髓、脑桥和中脑的正中缝及其附近网状结构的一系列小核团所组成的核群的总称。

On magnetic resonance imaging, PSP is characterized by atrophy of the midbrain tegmentum. The atrophy of the rostral MT, when detected by mid-sagittal MRI, looks like the bill of hummingbird and is therefore referred to as the "hummingbird" sign.

在MRI上PSP表现为中脑被盖部萎缩；在正中矢状位上，中脑被盖部嘴缘的萎缩看起来像是蜂鸟的鸟嘴，因此称为"蜂鸟征"。

The mid-sagittal MRI in PSP patients includes the regions of the most rostral midbrain, the midbrain tegmentum, the pontine base, and the cerebellum, and these images on MR appear to correspond to the bill, crown, body, and wing, respectively, of a hummingbird.

PSP患者的中脑嘴、中脑被盖部、脑桥基底部、小脑再MRI正中矢状位上看起来分别与蜂鸟的鸟嘴、鸟颈、鸟身、鸟翼相似。

After varied survival periods, the model mice were sacrificed to get the specimens of SN fixed, embedded and coronally sectioned continuously. The microsections were processed by immunohistochemistry to label the DA neurons and Calbindin D28k-containing neurons with the antibodies against tyrosine hydroxylase and CR respectively. The labeled cells were counted under microscope and analyzed statistically.

模型动物存活1周后，一部分取其中脑黑质节段，固定、包埋做连续冠状石蜡切片，以免疫组织化学染色方法，显示各组酪氨酸经化酶和钙结合蛋白表达阳性细胞，光镜观察并细胞计数，统计学分析；另一部分取其中脑黑质组织匀浆，行TH、CB的Westem blot免疫印迹方法检测，用LabWorks软件分析处理。

Following brain stem injury,the number of GFAP-positive astrocytes in cerebral cortex and pervent-ricular area,dorsomedial and ventro-medial pafts of midbrain at 30 min antemortem,and in periventricular area,dorsomedial part of pens,dorso-medial and ventro-medial part of medulla oblongata at 60 min antemortem.

采取针刺法造成实验大白鼠脑干损伤，用免疫组织化学LSAB法检测大脑、中脑、桥脑及延髓等不同部位脑组织中胶质原纤维酸性蛋白的改变。结果发现，生前损伤30min，大脑顶部灰质及中脑腹例中央部的GFAP阳性星形胶质细胞数目增多；生前损伤60min，除大脑顶部灰质及中脑腹侧中央部外。

Rat ventral mesencephalic precursors can be induced to differentiate into plenty of tyrosine hydroxylase-positive DNs, mainly originating in A10 regions.

大鼠腹侧中脑多巴胺能前体细胞可在体外大量诱导分化成酪氨酸羟化酶阳性的主要源自中脑腹侧被盖区(A10)的多巴胺能神经元。

The efferent projections of hypothalamic and brain stem nucleuses to nucleus dorsalis nervi vagi were studied by means of the retrograde axonal transport of HRP technique in cats.

本文用HRP轴突逆行输送法，对猫下丘脑和脑干一些核向迷走神经背核的传出投射进行了研究。将HRP注射至迷走神经背核后，较多的标记细胞见于同侧下丘脑的室旁核、背内侧核以及中脑的中央灰质和被盖腹内侧区。

Morphological changes of degeneration, necrosis, apoptosis and immunohistochemieal changes of ncNOS, caspase-3, Fas and Bax resulted by opiums abuse in neurons could be regarded as morphological markers and pathological indicators in forensic diagnosis and identification.

海洛因、吗啡、度冷丁药物滥用引起的大脑皮质、中脑导水管周围灰质和中脑腹侧被盖区神经细胞变性、坏死、凋亡等形态学改变以及ncNOS、caspase-3、Fas、Bax免疫组织化学染色变化可作为阿片类药物滥用法医学鉴定的形态学辅助指标。

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。
