后连合

In normal group and sham lesion group, BDA positive neurons were distributed symmetrically in the pyramid cells of sensorimotor cortex, and BDA positive fibers of pyramid cells passed through the cerebral cortex, internal capsule, cerebral peduncle of midbrain, basilar portion of pons to the pyramid of medulla oblongata. At the lower part of the medulla oblongata, most of the BDA positive fibers passed through the pyramidal decussation to the contralateral side, continously descended at the ventral part of posterior funiculus just dorsal to the posterior gray commissure and ended at sacral spinal segments.

正常组和假损伤组大鼠BDA示踪显示BDA标记阳性细胞定位于双侧感觉运动皮层的锥体细胞，锥体细胞发出的BDA阳性纤维束对称分布于双侧皮层、内囊、大脑脚、脑桥基底部、延髓锥体中的皮质脊髓束内，继而经锥体交叉到脊髓后索，在双侧后索最深层、灰质后连合背侧下行至脊髓骶段。

The posterior margin of hippocampal volumetry was defined by the plane which intersected the posterior commissure.

体积测量后界定在后连合，手工勾画出HF边缘获得面积，并依此获得HF体积。

It was more appropriate to define the posterior commissure as the posterior margin of HF volumetry, the determination of volume range of HF was helpful in lateralization of temporal lobe epilepsy. 3D MPRAGE was superior to SE in the volumetry of HF.

后连合作为HF体积测定后界较合适，HF正常值的制订有利于颞叶癫痫的定侧。3D MPRAGE序列较SE序列用于HF体积测定更为优越。

Previous studies have suggested that the dorsal commissural nucleus of the lumbosacral spinal cord is central for the intergration and transmission of sensory information from both somatic and visceral organs.

In rats receiving infusion of 100 μl of 2%formalin into the urethra, a large number of FOS-positive neurons were seen in the lumbosacral cord segments (L6 and S1), and they were primarily distributed in the medial dorsal horn and dorsal commissural nucleus.

在向大鼠尿道内导入100 μl 2%福尔马林后，大量FOS阳性神经元出现在脊髓腰6和骶1节段的后角内侧部和后连合核内。

目的 采用行为学和免疫荧光化学的方法，观察直肠扩张刺激对IBS大鼠痛行为学以及大鼠骶髓后连合核(dorsal commissural nucleus， DCN)中神经元和胶质细胞的影响，为探讨IBS发生机制提供理论依据。

Objective To study the changes of behavior and expressions of glial fibrillary acidic protein in dorsal commissural nucleuse and thalamic intralaminar nuclei in formalin induced acute colitis in rats. Methods An animal model of acute colitis in visceralgia rats was used in this study.

目的 探讨因福尔马林引起的大鼠急性结肠炎刺激诱导的行为学变化及骶髓后连合核(dorsal commissural nucleuse， DCN)和丘脑板内核群(thalamic intralaminar nuclei， ILN)胶质原纤维酸性蛋白(glial fibrillary acidic protein， GFAP)的表达及其意义。

The effects of Zn2+ on GABAA-receptor mediated responses in acutely isolated rat sacral dorsal commissural nucleus were studied using nystatin-perforated whole cell rechniques .

采用制霉菌素穿孔膜片箝技术，研究了锌离子（Zn2+）对急性分离的大鼠骶髓后连合核神经元GABAA受体介导电流的作用。

In summary, the present study revealed that Barrington's nucleus and D-region received direct projection fibers from the sacral spinal neurons in lamina I, parasympathetic nucleus and dorsal commissural nucleus; periaqueductal gray also received afferent projections from the lumbosacral spinal cord and sent projection fibers to the Barrington's nucleus and D-region.

上述结果说明：大鼠腰骶髓 I 层、骶髓副交感核和后连合核神经元发出的投射纤维直接终止于 Barrington's 核和 D 区内；导水管周围灰质也接受来自腰骶髓的投射纤维，同时发出纤维终止于 Barrington's 核和 D 区内。

Therefore, in the present study, a retrograde and anterograde experiments were made in the rat to address this issue. After injection of cholera toxin B subunit, a retrograde tracer, into Barrington's nucleus or D-region, some retrogradely labeled neurons were found in lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus of the lumbosacral spinal cord segments. Injection of biotinylated dextran amine into lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus, respectively, a large number of BDA-labeled axon terminals were seen in Barrington's nucleus and D-region.

发现，将逆行示踪剂霍乱毒素 B 亚单位（ Cholera toxin B subunit； CTb ）注射到 Barrington's 核或 D 区后，在大鼠腰骶髓 I 层、骶髓副交感核和后连合核内分布有一定数量的 CTb 逆标神经元；将顺行示踪剂结合生物素的葡聚糖胺(Biotinylated dextran amine； BDA)分别注射到腰骶髓 I 层、骶髓副交感核和后连合核内后， Barrington's 核和 D 区内出现大量顺行标记的轴突终末。
