内鞘

视神经减压术管内鞘切开部位宜选择在鞘的外、上壁交界外。

It would be safe to incise the superior lateral wall of intra canal optic sheath in the decompression of optic nerve .

普瑞巴林通过腹膜内或鞘内给药剂量逐渐增加直到产生抗痛觉超敏作用或出现运动受损。

Pregabalin was administered either intraperitoneally ( IP ) or intrathecally ( IT ) and dosed up incrementally until an antiallodynic effect without sedation or motor impairment was apparent .

结论：1.从新生大鼠海马和嗅球分别分离培养的神经干细胞和嗅鞘细胞共同移植到AD大鼠脑内，嗅鞘细胞能够促使神经干细胞存活，增殖和向胆碱能神经元分化。

Isolation neural stem cells and olfactory ensheathing cells respectively from hippocampi and olfactory bulb of neonatal rat , and then transplantation to the AD rats , olfactory ensheathing cells can promote neural stem cell survival , proliferation and differentiation of cholinergic neurons . 2 .

最后计算了在负偏压脉冲持续时间内离子阵鞘层边界的扩展。

Finally , the propagation of ion matrix sheath boundary during the negative pulse duration is calculated .

三角形小管发是一种内毛根鞘角化缺陷病：1例张力细丝结构异常的超微结构观察报道

Pili trianguli et canaliculi is a defect of inner root sheath keratinization : Ultrastructural observations of anomalous tonofilament organization in a case

目的观察微创引流术治疗脑室出血并鞘内注射（鞘注）药物预防脑积水的疗效。

Objective To evaluate the therapeutic effects of treating intraventricular hemorrhage by mini-invasive drainage and preventing hydrocephalus by infusing the drugs to lumber cistern .

研究结果显示，容器内表面附近鞘层扩展到附加电极后，其中的离子逐渐都注入到容器内表面、电场分布逐渐趋于稳定。

The simulated results show that after the sheath expands from near the inside wall of the cup to the auxiliary electrode , the ions can be gradually implanted into the inner walls ;

由于受到鞘层电场的约束作用，负离子主要分布在等离子体区内，在鞘层附近负离子密度迅速下降，电子密度在鞘层边缘处接近正离子密度，由双极扩散形成鞘层电场。

Because the negative ions are constrained in the plasma region by the strong electric field in the sheath , their densities decrease apparently near the sheath region , where the density of positive ions and electrons get closer .

结论：嗅鞘细胞可在冻融周围神经移植物中存活2￣3wk，神经周边部位较实质内更有利于嗅鞘细胞生长，这种移植物不能发挥促进视神经再生的作用。

CONCLUSION : The OECs can survive for 2 ~ 3wk in the freeze-thawed PN grafts with the peripheral areas being more beneficial for the survival and growth of OECs . Such freeze-thawed PN grafts can not promote the axonal regeneration of RGCs .
