The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

给药局部肉眼观察未见明显的纤维组织增生；HE染色可见B、C、D三组给药后四周及八周时硬膜内外均有炎细胞浸润，纤维细胞轻度增生，硬膜外神经根内有炎细胞浸润及炎性渗出；特殊染色B、C、D三组同A组相比未见有脊髓及神经根的改变；免疫组化染色，给药后四周及八周时，硬膜内外均有Ⅱ型胶原纤维增生；固兰染色B、C、D三组未见有明显脱髓鞘改变，与A组相比无明显异常改变；电镜观察B、C、D三组在给药后的四周及八周时，表现为硬膜外神经根内髓鞘厚薄不一，形状不规则，可见成纤维细胞，神经内膜中可见有巨噬细胞；粗大的有髓神经纤维变化明显，无髓神经纤维受累较轻；八周时电镜下D组改变较B、C两组为轻。

Results In both groups after injury, several changes on oculomotor nerve occurred including number reduction of neurons, dispersion in distribution, disappearance of sub-nuclear structure, structure destruction of fibers and myelin sheath, neurite gemmation, and specificity decrease in fibers distribution, while all these changes in section-suture group were more obvious.

结果 不同损伤均可导致神经元的数量减少，分布散乱，亚核分布结构改变，神经纤维和髓鞘的结构破坏，轴突芽生及再生纤维分布的特异性降低，而且上述改变在神经切断组更加明显。

ERK positive cell mainly distributed at nucleus of solitary tract, ambigous nucleus, and positive fibers and cells mainly distributed at medullary visceral zone, nucleus of solitary tract and ambigus nucleus. These positive cells formed an isolated zone from nucleus of solitary tract via medullary visceral zone to SP5, which could be seen using immunohistochemical stain. Positive cells and fibers also distributed at the projection from pneumogastric nerve to the stem.

免疫组织学染色可见，阳性细胞主要分布于延髓内脏带的孤束核和疑核、阳性纤维伴随阳性细胞分布于延髓内脏带的孤束核区和疑核、呈沿孤束核经延髓内脏带至三叉神经脊束核的弧行带；在迷走神经向脑干投射部位也可见阳性胞体和纤维的分布。

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

MAIN OUTCOME MEASURES: The density and size frequency distribution of sciatic nerve medullated fibers, as well as the number, the maximum diameter and the mean diameter of medullated fibers in two group of 0la rats and 6J rats.

主要观察指标：两组中O1a鼠和6J鼠坐骨神经的有髓纤维密度、有髓纤维数目、有髓纤维最大直径、有髓纤维平均直径。

The osteofibrous apertures,osteofibrous canal and the tendious decussating fibers of the nuchal muscles passed through by the greater occipital nerve are the anatomic basis of the greater occipital nerve compression syndrome.
