Coleoptile length were observed in different varieties, and the differences among varieties were consistent under different simulated drought stresses, therefore, coleoptile length could be used in the evaluation of drought in wheat at the early stage.

在不同程度的干旱胁迫处理下，各品种的胚芽鞘长度变化趋势大致相同，因此利用胚芽鞘长度可以在早期对小麦的抗旱性进行鉴选。

A rapid, efficient protocol to detect the toxicity of Cu2+ stress using wheat coleoptile, which is simple, uniformal in structure and sensitive, was established. By using this model, the mechanism of Cu2+ stress leading to the inhibition of cell elongation was also studied.

本文以小麦为材料，研究不同浓度Cu2+对小麦种子萌发和幼苗生长的影响及机理；利用小麦胚芽鞘结构简单、反应敏感的特点，探索建立小麦胚芽鞘快速检测铜离子毒害模式，并利用此模式研究了铜离子胁迫对细胞伸长抑制作用的机理。

Objective To investigate the effect of interferon intratheca! injection curing virosis encephalitis and observe the concentration change of interferon in cerebrospinal fluid before and after the treatment.

目的探讨鞘内注射干扰素治疗病毒性脑炎的疗效，并观察脑脊液中干扰素浓度在鞘内注射前、后的变化。

In particular,peripheral contrast enhancement with separations of an intradural extramedullaty tumor on MRI will suggest the diagnosis of schwannoma.

椎管内髓外硬膜下神经鞘瘤的MRI特征，有助于椎管肿瘤的鉴别诊断，尤其是伴有瘤内分隔性周围强化，应提示神经鞘瘤。

Schwannomas are typically benign, slow growing tumors that arise from the schwann cells, which envelop and myelinate cranial, spinal, and peripheral nerves.

神经鞘瘤是典型的良性、缓慢生长的肿瘤，起源于许旺细胞，包绕并形成颅内、脊髓以及周围神经髓鞘。

Part 4: Brain-derived neurotropic factor genetically modified olfactory ensheathing cells of the neonatal rat Objective To culture the olfactory ensheathing cells from the neonatal rat and modify them genetically by human Brain-derived neurotropic factor to increase the formation of neurophic factors. Methods The OECs were dissociated from the neonatal rat olfactory bulbs and purified with time-speed difference stick.

第四部分：脑源性神经营养因子基因转染新生大鼠嗅鞘细胞目的为提高嗅鞘细胞(Olfactory ensheathing cells，OECs)分泌脑源性神经营养因子(BDNF，Brain-derived neurotropic factor)的能力，探讨将外源性BDNF基因转染入OECs，为今后采用BDNF基因修饰的OECs移植治疗SCI奠定基础。

However, in the absent of LEF-2, the formation of viral nucleocapsid derived from lef-2 ko bacmid appeared to be normal under transmission electron microscope, suggesting that the life cycle of lef-2 ko bacmid could proceed through DNA replication to viral pakckaging unimpededly.

虽然病毒之复制受到lef-2基因缺失的影响，但由於病毒之构造蛋白仍可表现，如鞘蛋白(VP39)等，因此经由穿透式电子显微镜观察，可知缺失lef-2之病毒仍可有正常的核酸蛋白鞘形成。

Improving the activity of SOD can postphone aging of leaf and decreasing of photosynthesis, decrease the exportation of carbohydrate of stem-sheath matter, promote transportation of carbohydrate to axillary buds, and increase the ratooning ratio.

提高叶片中SOD活性，能有效延缓叶片衰老，延缓叶片光合同化作用的下降，减少茎鞘碳水化合物的输出，促进茎鞘碳水化合物向腋芽输送，促进腋芽萌发，提高水稻再生率。

The fixatives were used in green-maintaining Costus SpeciosusSmith under different conditions, such as the different amount of fixatives, which temperature and time of blanching, steriliing under 96℃, 105℃, 118℃ and at different time in the can.

使用不同用量的不同护绿剂，采用烫漂、常温浸泡及真空渗透等护绿措施，对闭鞘姜护绿效果进行比较；装罐后分别于96℃，105℃，118℃三种温度及不同时间下进行杀菌试验。结果表明：用浓度各为100 mg／kg的硫酸铜和亚硫酸钠混合护绿液，在95℃温度下烫漂2.0 min，护绿效果最好；而最佳杀菌式为：10'-15'-10'/118℃。所得闭鞘姜罐头在室温下可贮藏14个月，绿色保持不变，感官质量得到改善

AIM: To analyze the apoptosis and proliferation of HERS (Hertwig's epithelial root sheath) and to evaluate the roles of HERS cells in the development of cementum.

目的：观察牙根发育中上皮根鞘细胞(Hertwig's epithelial root sheath， HERS)断裂后结局和增殖凋亡相关基因的表达，探讨上皮根鞘在牙根发育特别是牙骨质形成中的可能作用。

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。
