Objective To study the levels of brain-derived neurotrophic factor protein in experimental dogs using multiple cauda equina constrictions throughout the entire lumbar, sacral and coccygeal spinal cord and their central processes of the dorsal root ganglia neurons resulting in the acute and severe cauda equina syndrome.

目的研究实验性犬急性重度马尾神经压迫48h的相关脊髓和背根神经节（dorsal root ganglion，DRG）内脑源性神经营养因子（brain-derived neurotrophic factor，BDNF）蛋白表达水平。

After heart perfusion, the spinal cord and brainstem were removed, and post-fixed overnight, then coronally sliced into 25μm thick of each piece.

取出后过量戊巴比妥钠麻醉，心脏灌流，取脊髓和脑干，后固定过夜，冰冻切片，片厚25μm。

Right MCAO was induced in all animals by a 4-0 nylon thread with round tip inserted cranially into right internal carotid artery and maintained for 90 min. HSP70 mono-clone antibody immunocytochemistry was used to detect the changes of HSP70 expression in rat cortex at 6, 12,18,24,48 and 72h reperfusion in conjunction with histopathological analysis of rat brain.

应用HSP70单克隆抗体免疫组化染色检测大鼠再灌注6、12、18、24、48及72h脑皮质HSP70表达的变化；并与病理组织学改变进行对照研究。2.20只雄性新西兰大白兔随机分成对照组（n=10）及葛根素组（n=10），所有动物均阻闭腹主动脉肾下段20min，建立兔脊髓腰尾段缺血模型。

The dose of the craniospinal irradiation was 36Gy and the total posterior fossa dose was 54Gy.

全脑全脊髓剂量36Gy，后颅窝局部加量至54Gy。

E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。

The cell from hippocampus, striatum, ependyma, thalamus opticus, olfactory bulb, cortex, brain stem, cerebellum, and spinal cord in human fetal brain were studied using HE staining and immunocytochemistry.

应用HE染色和免疫细胞化学方法观察人胎脑室管膜下区、海马、纹状体、丘脑、嗅球、皮层、脑干、小脑、脊髓的Nestin阳性细胞。

RESULTSThe branches of aortic arch are the left and right innominate artery in pate of mini-pig.

结果小型猪主动脉弓部向头颈部分支为左、右无名动脉；双侧颈内动脉均来自右无名动脉，故右无名动脉对脑底供血十分重要；双侧有沿脊柱向尾侧走行的折返动脉；胸主动脉背侧由胸6至胸14平面共发出8条肋间动脉，为胸腰脊髓的主要供血动脉；无腰大动脉。

Results After the electrical stimulation, the Fos-IR neurons were observed in many areas in the brain: the upper cervical spinal dorsal horn, spinal trigeminal nucleus caudalis, raphe nuclei, periaqueductal gray matter, interpeduncular nucleus, and hypothalamus.

结果 电刺激后Fos阳性神经元在脑内分布广泛，主要集中在高颈段脊髓后角，三叉脊束核尾侧亚核，中缝核簇，中脑导水管周围灰质，脚间核及下丘脑等区域。

The median survival of the irradiated patients was 6 months and that of the un-irradiated ones, 2 months.

脑MRI示病变消失和缩小分别为2例和4例，脊髓MRI示病变消失1例，缩小3例。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
