实验用多管微电极细胞外记录氨基甲酸乙酯麻醉的SD大鼠延髓头端腹外侧区神经元的活动。

After HRP application to the rostral area (n=10), quite a number of labelled cells were distributed at the ventrolateral part of the nucleus of trapezoid body, the lateroventral periolivary nucleus and the retrotrapezoid nucleus. After HRP application to the caudal area (n=10), HRP labelled cells were mainly located at the lateral reticular nucleus and the ventral part of at the lateral paragigantocellular nucleus LPGi. After HRP application to the intermediate area (n=6), only 8HRP labelled cells were observed at the in 6rats. After HRP application to the control area (n=4), only 6HRP labelled cells were found at the rostral ventrolateral reticular nucleus.

大鼠延髓腹外侧表面的头端化学感受区表面敷贴辣根过氧化物酶后，在延髓斜方体核、外周橄榄腹外侧核和斜方体后核均有HRP标记细胞存在；于尾端化学感受区表面敷贴HRP后，在延髓的巨细胞旁外侧核、外侧网状核和舌下神经核有HRP标记细胞存在；于中间区表面敷贴HRP后，在6只大鼠的延髓内部区域仅观察到8个HRP标记细胞；于对照区敷贴HRP后，在4只大鼠的延髓内部区域仅观察到6个HRP标记细胞，散在地分布在头端腹外侧网状核。

After HRP application, HRP labelled cells were distributed in the nucleus of trapezoid body , lateroventral periolivary nucleus , retrotrapezoid nucleus , lateral paragigantocellular nucleus and lateral reticular nucleus . The findings demonstrated the existence of neural structural relations between the chemosensitve areas and the Tz, LVPO, NRT, LPGi and LRt, and revealed that these nuclei might participate in the mechanism of central chemical regulation on respiration.

观察到用浸有HRP的滤纸局部敷贴于延髓腹外侧表面化学感受区后，在延髓斜方体核、外周橄榄腹外侧核、斜方体后核、巨细胞旁外侧核和外侧网状核等核团找到HRP标记的细胞，表明上述延髓内部核团与腹外侧表面化学感受区之间存在神经结构联系，提示延髓腹外侧表面化学感受区对H〓等物质的化学感受机制可能与上述核团神经元伸向该区的突起有关。

结果如下：(1)在泰和乌鸡和江汉鸡的延髓中，NPY阳性神经元主要存在于下橄榄核，网状核及中缝核也少量出现；(2)在泰和乌鸡和肉鸽的小脑中，NPY阳性神经元主要存在于小脑皮质的蒲肯野氏细胞层，且以小叶顶端的蒲肯野氏细胞阳性明显，而小脑皮质的分子层、颗粒层未见阳性反应细胞；(3)泰和乌鸡延髓的网状细胞核非常发达；泰和乌鸡小脑皮质分3层，由外至内依次为分子层、蒲肯野氏细胞层和颗粒层；小脑分10叶，Ⅰ、Ⅱ和Ⅹ为单叶，其余各叶都分为2～3个小叶；(4)非洲鸵鸟迷走神经运动背核和疑核特别发达，孤束核吻侧部不发达。

Of the 26 lesions with pontine and bulbar involvement, three had no association with other lesions (Fig 2). Twelve were associated with tegmental and superior cerebellar peduncular extension, and six showed corticospinal tract involvement in continuity with an MDJ lesion. In one patient with additional telencephalic lesions, the right side of the pons was hyperintense on long TR/TE images that did not cross the midline, suggestive of an arterial lesion (Fig 3). In two patients with pontine tegmental lesions, there was an associated middle cerebellar peduncle and deep cerebellar white matter involvement (Fig 4). Two others had associated cervical lesions.

在26处脑桥延髓区病灶中，3处病灶仅限于脑桥延髓区，其它部位无病灶（图2）；12处病灶还同时伴有背盖部和小脑上脚/结合臂处病灶；6处病灶为与中脑-间脑接合处病灶相连的皮质脊髓束受累；还有1例患者除端脑见病灶外，右侧脑桥于T2像也见高信号病灶，但未超越正中线，提示可能系动脉病变所致（图3）；2例脑桥背盖部病灶的患者同时伴有小脑中脚/小脑脑桥脚和小脑深部白质受累（图4）；还有2处脑桥延髓区病灶还同时伴有颈髓病灶。
