Culm sheaths persistent or late deciduous, brown, shorter than internodes, fragile, densely setose; auricles falcate; oral setae ca. 5 mm; ligule arcuate, ca. 2 mm; blade triangularly ovate-lanceolate, abaxially slightly hairy at base.

In our stydy, we explored the expression pattern of COX-2 in normal rat Pilosebaceous Unit and hair follicle cycle adopting immunochemistry and RT-PCR methods.

毛囊皮脂腺单位中COX-2仅在表皮基底上层细胞和皮脂腺中，而在毛囊各层细胞中基本未见表达(仅在特化的触须毛囊外根鞘有轻微表达)。

Systematic aerobic exercise upregulates expression of enzyme genes concerning tricarboxylic acid cycle, and downregulates expression of genes concerning muscle protein synthesis and sphingolipid. It is suggested that aerobic exercise is good to protect human nerves' integrity, exerts positive action on anti-aging and accelerate the aerobic metabolism of lipid materials in vivo.

有氧运动可使三羧酸循环相关酶基因表达上调，肌肉蛋白合成相关基因和神经鞘脂类相关基因表达下调，提示有氧运动有助于保护神经细胞的完整性，对抗衰老有积极作用，同时可加速体内脂类物质有氧代谢。

Results Most OECs were bipolar or tripolar, and the purity was estimated to be over 88.7%. The non-OECs cells consists of astrocytes, neurons, oligodendrocytes and fibroblas.

结果 体外培养的新生小鼠嗅鞘细胞主要为双极或三极细胞，其纯度可以达到88.7%以上，污染细胞中有星形胶质细胞、神经元、少突胶质细胞和成纤维细胞。

Malignant peripheral nerve sheath tumor is an aggressive spindle cell sarcoma that is closely associated with neurofibromas, neurofibromatosis type 1 and from the sites previously irradiated.

恶性周边神经髓鞘瘤是一种恶性纺锤细胞肉瘤，和神经纤维瘤、第一型多发性神经纤维瘤症和以前接受过放射治疗的部位有密切相关。

Small infarcts occur in the white matter and deep grey matter while the cerebral cortex is sparing.

患者脑部的白质和深层灰质中有多发性小梗死和弥散性脱髓鞘。

Results In healthy subjects, L2-L5 nerves were displayed clearly by MRN, with a round or ellipse ganglion of 3-6 mm in diameter, and smooth stick-like nerve root and trunk, 2-5 mm in diameter. The signal intensity was higher in ganglion than nerve root or trunk. 40% of nerve root sheath was surrounded by small amount of cerebrospinal fluid, Femoral nerve was displayed in all subjects, while only 83.3% of obturator nerve and 43.3% of lumbosacral trunk were manifested. Lamellar blurred hyper-signal intensity was seen around 80.9% of lumbar plexus in GBS, but none in CIDP.

结果 正常组MRN可清晰显示腰2~5神经的走行，神经节呈圆或椭圆形膨大，大小约为3~6mm，神经根及干呈条状、边缘光滑，大小约为2~5mm、神经节信号高于神经根和干，40%的神经根鞘有少量脑脊液，股神经、闭孔神经、腰骶干的显示率分别为100%、83.3%、43.3%。80.9%的GBS腰丛神经周围有片状模糊高信号，神经根和节大小和信号无明显改变，25%神经干增粗，50%的神经干信号增高，边缘模糊。

Once the position of the device was found to be satisfactory and without or with only a trace to small residual shunt was confirmed, the device was released by turning the cable counterclockwise using the pin vise.

选择大于所测PDA最窄直径2～4 mm的Amplatzer封堵器，于透视下经6 F输送鞘管将其封堵于PDA处。10分钟后重复主动脉造影，若封堵器形状、位置满意，无或仅有微～少量残余分流时，可释放封堵器。

①The root sheath is easier to be damaged by the length and diameter becoming bigger.

腰神经根受挤压是引起腰腿疼痛、间歇性跛行等腰部疾病的病因之一，其挤压部位和原因很多，其中之一与神经根鞘受压或张力改变有重要关系[1] 。

The biological adhesive a-gent from human plasma was composed of fibrino-gen coagulase and medullary sheath of the nervetaken at the anasomosis region were studied histol-gically.

从组织学观察发现，粘合法修复的神经，其神经外膜较完整，肉芽肿形成轻，髓鞘退变较少。与缝合法修复之间有显著性差异。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
