RESULTSdiabetic rats showed typical symptoms involving elevated serum glucose and weight loss (2)The rats in DM+VaD group reacted slower and made more error numbers in Y-maze than the rats in VaD group did, with a prolonged total reacting time in a whole day.(3)More neurons with serious damages, such as edema, ischemia or pyknosis could be found in DM+VaD group than in VaD group. More disarrangement of cone neurons, obvious glia proliferation, and more neuron apoptosis were found in CA area of hippocampus. CONCLUSIONS (1)2-VO in STZ-induced diabetic rats succeeded in establishing VaD animal models.(2) The cognitive dysfunction induced by VaD rats had been deteriorated by diabetes mellitus.(3)Morphology evidences proved that diabetes mellitus aggravated brain damages induced by VaD.PART II Effect of diabetes mellitus on the cholinergic nervous systemin CA1 area of hippocampus of VaDOBJECTIVE To estimate the role of cholinergic nervous system in hippocampus during the process of cognitive dysfunction aggravated by diabetes mellitus in DM+VaD group. METHODS Observe the changes of ChAT protein by immunohistochemistry stain. Chose three rats randomly from each group at each pointat two week, four week, and eight week, then sepa

Egg apparatus The three haploid nuclei that are situated at the micropylar end of the embryo sac in most flowering plants. The central nucleus is the female gamete and those to either side of it are called the synergids.

卵器：在大多数显花植物的胚囊中，位于珠孔端的三个单倍体核，其中卵细胞位于中央，两个助细胞分别位于两边。

The study has an original significance in the elucidation of the function of TR in normal cells.

本项目在揭示TR 在正常细胞中的功能方面具有科学创新性，并可能为端粒酶的研究提供新的内容和思路。

Objective: To construct expression vector of hTERT-hIL-18 fusion gene in eukaryotic cells and to study its biological function.

目的：以基因重组技术在真核细胞中表达人白细胞介素18(hIL-18)和人端粒酶逆转录酶融合基因，并观察其生物学功能。

These DSs were first observed at 9 weeks in the distal part of ascending fibers that consist of gracile fasciculus and cerebellospinal-gracile nucleus and white matter of cerebellum. They extend along medulla oblongate to medulla cervix、medulla thorax、medulla lumbalis in accordance with dying-back type degeneration. The corticospinal tract were affected at 18 weeks,and thalamus、the olfactory pathway、the visal pathway、the auditory pathway were affected at 32 weeks.

这种DS从9周龄开始，首先在构成薄束路和脊髓小脑后路的上行纤维的远端区域-薄束核区和小脑白质出现，逐渐按照延髓、颈髓、胸髓、腰髓的顺序，向细胞体方向逆行性地进展。18周龄时波及到锥体路，32周龄时进一步波及到丘脑和嗅觉、视觉、听觉传导路。

The protein encoded by this sequence was deduced to be consisted with 213 amino acids, signal peptide sequence from 1 to 17 position, and transmembrane regions from 171 to 190 position, whose grand average of hydropathicity is computed to be 0.031, secondary structure is composed by alpha helix (57.28%), extended strand (6.57%) and random coil (36.15%), subcellular localization was cytoplasmic by CELLO v.2.5. There are some function sites predicted by PROSCAN software, such as one N-glycosylation site (151-154aa), one protein kinase C phosphorylation site (193-195aa), two casein kinase II phosphorylation sites (155-158aa and 173-176aa), and one N-myristoylation site (97-102aa).

推测编码蛋白由213个氨基酸组成，信号肽序列位于1-17aa，亲水性指数为0.031，跨膜区域位于171-190aa，二级结构由-螺旋（57.28%）、延伸主链（6.57%）和无规卷曲（36.15%）组成；亚细胞定位于细胞质，含有N-糖基化位点1个(151-154aa)，蛋白激酶C磷酸化位点1个(193-195aa)，酪蛋白激酶Ⅱ磷酸化位点2个(155-158aa and 173-176aa)，N端酰基化位点1个(97-102aa)。

The interaction between the N- and C-terminal heptad repeat regions of the gp41 extracellular domain leads to the formation of a six-helix bundle (6-HB), representing the fusion-active gp41 core.

当gp120与靶细胞表面的CD4及共受体结合后，gp41胞外段N-末端重复序列与C—术端重复序列相互作用，形成六螺旋束(6—HB)，即gp41融合活性核心，从而导致病毒融合。

The heteroploid rate was higher in positive telomerase tissues.

5端粒酶阳性的子宫内膜癌组织细胞异倍体比例较高。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
