The characteristic hyperattenuation on unenhanced CT scans reflects the high nuclear-cytoplasmic ratio seen at histologic analysis.

平扫CT的特征性高密度反应了相应组织学上高核质比。

The expression of GFAP in ILN was significant at 60 mm and it decreased obviously at 120 min after animal model induced. Conclusion Behavior changes in rats are mediated by visceralgia, which induces acute colitis. The change of GFAP in gliocyte, which is closely related with pain, emerged early and remarkably. The change of ILN, which is intensely related with emotion, appears lain.

大鼠痛行为学的变化是由于急性炎症引起的内脏痛而导致，与疼痛变化密切相关的胶质细胞中GFAP在脊髓内反应早且明显，而在与情绪变化密切相关的丘脑内的板内核群中变化相对较晚。

Zymologic analysis showed that the molecular weight of this β-mannanase was approximately 47 kD. The enzyme was stable when pH ranged from 5.0 to 6.5 and could be activated by Na+ and Ba2+. With an optimal temperature of 50°C. Action mode analysis of TLC re-vealed that the enzyme belonged to the endo-β-mannanase family.

酶学性质分析：该酶分子量约为47 kD，酶的最适反应温度为50°C，在pH 5.0~6.5之间该酶的稳定性较好； Na+和Ba2+对该酶有激活作用，用TLC对酶产物分析，表明该酶为内切β-甘露聚糖酶。

Researchers at the University of California, Los Angeles, and The Hospital for Sick Children in Toronto monitored neurons in the lateral amygdalae (two almond-shaped regions on either side of the midbrain associated with learning and memory) of mice to see whether the presence of the CREB protein plays a key role in signaling brain cells to make memories.

洛杉矶加利福尼亚大学及多伦多儿童医院的研究者们对小鼠外侧杏仁核部位（该部位是主管学习和记忆的中脑两侧杏仁状的区域）进行监测，以研究CREB蛋白（cAMP反应元件结合蛋白）是否在脑细胞形成记忆过程中起着至关重要的作用。

The treatment group（n=40） was treated with SASP（0.5g,4 times per day for oral use）,Danshen injection（20ml added in 5% glucose）combined with Liushen pill,Yunnan white powder retention enema,there were not immunosuppressive agent,odynolysis and constipating remedy for use;the control group（n=39） was treated SASP（1.0,4 times per day for oral use）combined with gentamycin and smectite retention enema,the course of treatment were 8 weeks,we observed the two groups therapeutic effects,the mucosa change under colonoscope,bowel mucosa pathohistology changes and drug adverse reaction.

治疗组44例，SASP（0.5g，4次/d，口服），丹参注射液20ml加入5%葡萄糖静滴联合六神丸、云南白药保留灌肠，不用激素、免疫抑制剂及止痛、止泻药物；对照组39例SASP（1.0g，4次/d，口服）及庆大霉素、思密达保留灌肠。疗程8周。观察两组临床效果、结肠镜下黏膜改变、肠黏膜病理组织学变化及药物不良反应。

The pharmacodynamics indicates that QingDai Li Shi Tang Decoction has heat-clearing and detoxicating,dampness dissipating and blood stasis removing.

药效学研究表明该药具有清热解毒、利湿止带、活血祛瘀的作用，且使用安全可靠，临床使用期间无不良反应，值得进一步研究和临床推广应用。

The density of the DC-LAMP+-cells of each slide was quanti fied by a Zeiss imaging system enregistering the percentage of the area occupied by DC-LAMP+-cells.

所有前哨淋巴结及非前哨淋巴结蜡块切片均行与DC-LAMP抗体免疫反应的免疫组织学检查以确认成熟树突状细胞。

The severity of tissue reaction to the extravasated contrast media depends on several factors: amount, osmolarity, and chemical components of contrast media.

对比剂的渗漏为日常放射线学检查常见问题，组织反应之严重程度与渗漏对比剂的量、渗透压、化学成份有关。

Hypothesizing that postmenopausal women might be particularly vulnerable to any adverse effects of HIV infection or on the skeleton, we initiated a longitudinal study to assess the prevalence of osteoporosis/osteopenia, determinants and etiology of low BMD and rates of bone loss in HIV+ postmenopausal Hispanic and African American women, who constitute the majority of new infections in women in the United States.

假设停经后女性可能特别容易发生HIV感染或是抗反转录病毒药物治疗对骨骼的不良反应，我们进行了一项纵向研究，以评估骨质疏松症/骨质低下的盛行率、以及HIV阳性停经后西班牙裔与非裔美国居民低BMD以及骨质流失的决定因子和病因学，这些人种构成美国新感染女性的绝大多数。

The results shown that both [Cu_2]~2+ and NR molecular can intercalates into the DNA double helix layer, and there is a competition between these two interactions. Furthermore, chemometrics approach, parallel factor analysis, was used to resolve the measured three-way CW-SFS data, which provided simultaneously the concentration information for the three reaction components, NR, [Cu_2]~2+ and NR-DNA, for the system at each equilibrium point. This PARAFAC analysis indicated that the intercalation of the [Cu_2]~2+ molecule into the DNA proceeds by exchanging with the NR probe, and can be attributed to two parallel reactions.

本工作以同步荧光技术采集了竞争作用的三维数据，并结合了化学计量学中的平行因子法对此三维数据进行分解，得到了各组分的荧光光谱图及各个反应平衡点各组分的相对浓度，平衡浓度的变化趋势也表明了铜络合物与中性红之间的竞争作用，进一步表明了铜络物与DNA的作用方式和中性红与DNA作用方式一样均为嵌插作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
