Methods In58cases,X-ray film,lumbar discography,CT examinations were done to confirm the diagnosis,then total laminectomig was performed to reveal the vertebal body without involving small arˉticular process.Intervertebral tissue was excised via duralotomy approach in2cases in remaining56cases,through right and left longitudinal syndesmotomy to resect the nucleus pulposus of lumber intervertebral disc.Results In58cases treated by operation,the operative findings were in according with the X-ray and CT examinations ofpre-opˉeration.

对58例患者进行X线拍片，腰椎碘造影，CT扫描检查，根据检查结果确诊后，采用全椎板切除显露椎体，未累及小关节突，2例经硬膜切开入路切除间盘组织，余56例经从双侧用神经剥离子带棉片将硬脊膜带神经根向中线剥拉至显露圆形突出物止，分别从左右纵韧带摘除髓核。

For the tetranuclear complexes,it is the firsttime that the magnetic susceptibility data have fittedsatisfactorily to the expressions which we havedemmived.

在链型杂四核配合物方面，首次用自己推出的磁化率公式对实验数据进行了最小二乘拟合。得到了令人满意的结果并作出了合理的解释。

The vascular bundle of stem is the type of double phloem. The anther is tetrasporangiate. Simultaneous cytokinesis in the microspore mother cell follows meriosis.

茎的维管束是双韧类型；雄蕊的花药四室，小孢子的形成为同时型胞质分裂，悬垂胎座，倒生胚珠，核型胚乳，果实成熟时胚仍处于球形胚阶段。

Results MRI showed symmetric abnormal signals in basal ganglia in 27 patients, in thalami and dentate nucleus in 21 patients, and in corona radiata-centrum ovale in 9 patients. All the lesions were hyperintensity on T1WI. Local hypointensity in basal ganglia was found in 4 patients, while hyperintensity or slight hyperintensity on both T2WI and T2-FLAIR were found in 26 patients, and slight hyperintensity with hypointensity on both T2WI and T2-FLAIR in 1 patient.

结果 27例颅脑MRI表现为双侧基底节区片状对称性异常信号，21例双侧丘脑、齿状核片状异常信号，9例双侧放射冠－半卵圆中心见片状对称性异常信号；27例T1WI上见高信号区，其中4例基底节区病灶内见小片状低信号；26例T2WI及T2-FLAIR见高或稍高信号，1例见稍高、低混杂信号。

In the course of present investigation in interspecific hybrid of Tritical crops, cytomixis mas observed at microspore stage, the present investigation deals with detailed analysis of this phenomenon at different conditions.

作者在麦类远缘杂种的减数分裂过程中发现，在减数分裂Ⅰ的前期和小孢子时期均存在核穿壁的现象，并对各种状态下的穿壁现象进行了详细的观察研究。

The result showed that the inhibition efficiency of the degraded ESPS with a low-molecular-weight on the nucleation and growth of CaOxa crystal was obviously superior to that of the undegraded ESPS.

结果显示，具有小分子量的降解ESPS对草酸钙晶体成核与生长的抑制效果明显优于大分子量的未降解ESPS。

Simultaneously the disappearance of microvilli, vacuolization of cytoplasm, dispersion of nucleus and appearance of apoptotic body were observed under transmission electron microscopy. All these morphological changes are hallmarks of apoptosis.

凋亡细胞经荧光染色后表现为细胞核固缩、碎裂；透射电镜下观察发现细胞微绒毛丧失，胞内出现空泡，胞核解体及形成凋亡小体等典型的凋亡特征。

In this research, the complete ipt gene was cloned from Agrobacterium pTiAch 58 Hind Ⅲ fragment and its promoter was re-constructed so that following three chimaeric genes were created:(1) ipt promoter plus ipt coding region and terminator ,(2) RuBP SSU 301 promoter from petunia plus ipt coding region and terminator ,(3) pea seed-specific vicilin promoter plus ipt coding region and terminator .

将ipt基因克隆后对其启动子进行了改造，分别构建了如下三种基因：（1）ipt启动子+ipt编码区和3′区，（2）磷酸核酮糖羧化酶小亚基启动子SSU 301+ipt编码区和3′区，（3）豌豆种子特异性启动子vicilin+ipt编码区和3′区。

The DNA follows a symmetrical path around the octamer.

注意，DNA&进&、&出&核小体的位点相距很近。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
