Methods:Via a cannula iserted into adominal aorta, Gey's balanced salt solution containing 0.025% collagenase P was perfused into rat normal pancreas. After digestion with collagenase P and protease, Nycodenz density gradient centrifugation was performed to isolate PSC. PSC was identified by its morphology, cytoplasmic lipid droplets and immunocytochemical staining for desmin, GFAP and α-SMA. Results:The production,viability and purity of isolated PSC were（15.3 ± 4.6）× 103／g body weight,（95.0 ± 3.5）%, and ﹥80％ respectively.

大鼠腹主动脉插管灌注后，经胶原酶消化、Nycodenz密度梯度离心，分离得到PSC；通过观察细胞形态、胞质内脂滴和免疫细胞化学方法检测结蛋白、神经胶质酸纤维蛋白（glial fibrillary acidic protein，GFAP）、α平滑肌肌动素（α-smooth muscle actin，α-SMA）的表达来鉴定PSC。

ConclusionsExpression of glucocorticoid receptor alpha was detected in the nuclei and cytoplasm in facial nucleus and peripheral lymph cells and was increased after facial nerve injuries. Local inflammatory reaction triggered by nerve injuries lasted for a longer duration than that caused by mere traumas.

h后。结论糖皮质激素受体α表达在面神经核团及外周淋巴细胞胞核及胞质中，在面神经受到损伤后其表达量增高，而且神经损伤较单纯外伤可以引起较长时间的局部炎症反应。

Results we found positive labeling for both anp and nos in different types of cells including the spiral modiolar artery, stria vascularis, spiral limbus, spiral ligaments, basilar membrane, organ of corti, spiral ganglion, and macula sacculi. however, no immunoactivity was found in the reissner membrane and tectorial membrane.

结果 在耳蜗各转螺旋动脉和血管纹，螺旋缘、螺旋韧带和corti器显示双阳性染色，螺旋神经节细胞及囊斑神经上皮细胞膜及轴突nos阳性染色，胞质anp阳性染色；盖膜、前庭膜阴性染色。

By use of perineurial recording technique in cutaneous pectoris of frog, we observed the effects of TSN on calcium currents in motor nerve terminals.

鉴于TSN主要生物学效应与胞内外钙离子密切相关，本文以不同方法研究了TSN对运动神经末梢钙电流、细胞胞内钙浓度以及对神经递质释放装置钙敏感性的影响，以期阐明TSN的作用机制。

The result showed that, the body wall most outer layer cuticle assumesthe translucent porodine, the surrounding entire body wall; Close isconnected with the cuticle 表皮层 for 合胞体 the structure, inthe back, the abdomen and its two sides separately adds thick to inprominent Cheng Jizhuang, separately contains the back side,腹侧the nerve and compares to the developed back, the abdomen nerve; Themyo- position to the body wall most inner layer, has the muscle cellto arrange becomes; Between the body wall and the digestive tractcavity is a body cavity; Digestive tract for 肌质 structure, afterinference for roundworm's esophagus.

结果显示，体壁最外层的角质层呈半透明的胶状，包围整个体壁；与角质层紧密相连的表皮层为为合胞体构造，在背、腹及其两个侧面分别加厚向内突出成脊状，分别包含背侧、腹侧神经和相比对发达的背、腹神经；肌层位于体壁最内层，有肌细胞排列而成；体壁与消化道之间的空腔为体腔；消化道为肌质结构，经推断为蛔虫的食道。

It has been proved by previous studies that peripheral nerve injury can induce a series of changes of expression of some neural active material and their receptors either in the somata or in the terminals of the damaged primary afferent neurons and motoneurons. These changes may reflect a re-ordering of metabolic priorities so that the synthesis of trophic factors or growth-associated proteins augmented while that of neurotransmitter-related proteins decreased.

以往的研究表明，周围神经损伤能够引起受损神经元(包括初级传入神经元和运动神经元)的胞体或终末内某些神经活性物质及其受体的表达发生一系列变化，其中与神经生长和营养有关的物质常发生上调，而与神经传递有关的物质则发生下调；与此同时，受损神经元的周围常伴随发生胶质反应及神经胶质增生等变化。

Results: Dynamic observation with histopathology and immunohistochemical staining showed that, after the nerve root nerve root compression, the myelinated nerve fibers decreased and there was ultrastructure changes of the nerve fibers, such as Schwann cell cytoplasm swelling and edema, Wallerian degeneration, and demyelinated degeneration of axons.

结果：通过对压迫神经根及神经根节大体观，组织病理学和免疫组织化学的光学显微镜的动态观察，可见神经根压迫后其有随神经纤维数目减少和超微结构的改变，如神经模细胞胞质肿胀和细胞水肿、华勒变性、神经轴突脱髓鞘变等。

On the other hand, we found for the first time that mammalian neurosteroids-like immunopositive nerve cell and its fiber existed in the brain vesicle and nerve tube of Amphioxus, and the positive substance distributed in the cytoplasm of nerve cell, while nucleus showed negative reaction.

本文研究还首次发现，文昌鱼脑泡和神经管中存在哺乳动物神经甾体激素样免疫阳性神经细胞及其纤维，免疫阳性物分布在神经细胞胞质，核显阴性反应。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
