Lipid peroxidation would cause the deficiency of myelinogenesis, Dysfunction of synaptic conduction and developmental anomaly of nerve cell if the deficiency of completely.

当硒缺乏时，硒蛋白活性降低，清除H2O2能力减弱，脂质过氧化导致髓鞘形成不良，突触传导障碍，神经元发育异常，造成严重的脑功能紊乱。

BACKGROUND: There is notan effective method for inducing bone marrow-derived mesenchymal stem cells differentiatied in to intervertebral disc cells.

摘要背景：目前尚缺乏诱导骨髓间充质干细胞向髓核细胞转化的体外模型。

In the control animals,the GAP-43-LI nerve fibers were found mainly distributed in association with vascular plexuses,with minor extension into the parenchyma of the inner zone of the periarterial lymphocyte sheath.In the immunized animals,in addition to denser vascular plexuses,more fibers appeared in the outer zones of periarterial lymphocyte sheath,the marginal zone,and the red pulp,all known to be the sites of active immune response.

于对照动物，脾GAP-43-LI神经纤维主要分布于血管周围，少量伸入动脉周围淋巴鞘的脾基质中，而在免疫刺激的动物，不仅血管周围的神经纤维明显增多，动脉周围淋巴鞘外层、边缘区和红髓等免疫应答活跃的部位也出现许多神经纤维。

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。

But there are a lot of disadvantage factors clagging the neurogeneration, such as the myelin-relative inhibitor, the information of glial scar and immune repulsive reaction.

关于干细胞及营养因子在损伤脊髓修复方面的研究虽已取得较大进展，但仍存在对神经再生的不利因素，如髓鞘相关抑制分子和胶质瘢痕形成，免疫排斥等。

We hae conducted coculture experiments to determine whether cells from the human NP can initiate the differentiation of human MSCs with or without cell–cell contact.

我们应用共培养的方法以判断是否来自于人椎间盘髓核的细胞能够诱导人间充质细胞的分化，包括直接和间接共培养。

Three healthy flap-eared New Zealand rabbits aged 4 months were aspirated on iliac crest under anesthesia for 6 mL bone marrow from which BMSCs were separated, then sacrificed and excised the lumbar intervertebral disc from which the nucleus pulposus cells were separated.

目的：针对椎间盘退行性变的组织修复目前集中于细胞移植治疗，实验在体外联合培养条件下观察骨髓基质干细胞对髓核细胞增殖分化的影响。

Objectives To study the response of neurons and astrocytes in Nucleus tractus solitarii after acute cardiac injury of rat.

目的 观察急性心肌损伤后大鼠延髓孤束核神经元和星形胶质细胞的反应。

Objectives To study the response of neurons and astrocytes in Nucleus Tractus Solitarii after acute cardiac injury of rat.

目的：观察急性心肌损伤后大鼠延髓孤束核(Nucleus Tractus Solitarii， NTS)神经元和星形胶质细胞的反应。

The response of GFAP positive-astrocytes peaked at 24 h, and then decreased. Conclusions Neurons and astrocytes in Nucleus Tractus Solitarii were activated sequently after acute cardiac injury, which suggested that the involvement neurons and astrocytes of NTS in the central modulation of cardiac pain after ACI.

急性心肌损伤后，大鼠延髓NTS中神经元和星形胶质细胞被心肌伤害性刺激激活，参与心肌损伤后疼痛的中枢调控。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
