小核

Thus small size nanodots with high density were obtained on vicinal substrate.

因此，有利于Ge纳米点的形核，并抑制纳米点的过度长大，从而获得高密度、小尺寸的Ge纳米点。

The rules of photo bioactivities are: Without illumination, the tested xanthene derivatives showed almost the same level of inherent toxicity to the same organism, which showed the inherent toxicity of xanthene derivatives were primarily dependent on the structure of parent molecule. Upon illumination, the photosensitizers showed obvious phototoxicity to all organisms. The xanthene derivatives showed stronger phototoxicity to Gram-positive bacteria. With the increasing number of halogen substituents, the singlet oxygen yields increased and the phototoxic activity increased too.

呫吨类化合物的生物活性的变化规律为：未经光照的条件下，呫吨类化合物的对同种待测微生物的固有生物活性基本相同，说明固有毒性可能主要决定于化合物分子的母核结构，其卤素取代基团对其影响较小；经实验光源照射下，所测MLC值明显低于未经光照条件下的值，表明呫吨类化合物对三种微生物的光敏活性明显强于对其相应的固有活性；呫吨类化合物对革兰氏阳性菌能发挥较大的光敏活性。

Cytokine-induced killercells are a cluster of alloplasm cells,which are prepared from the mononuclear cells of human peripheral blood that might be stimulated by some kinds of cytokines.The proliferation and cytotoxicity of CIK cells are high,and the side effect is low.CIK cell is a more effective anti-tumor effector cell in adoptive immunotherapy.

细胞因子诱导的杀伤细胞是人外周血单个核细胞在体外经多种细胞因子刺激后获得的一群异质细胞，它具有增殖能力强、杀瘤活性高和杀瘤谱广、临床应用不良反应小的特点，是肿瘤过继免疫治疗中更为有效的杀瘤效应细胞。

Results A 18 year old patient presented with 2 month's history of ambiopia. Computed tomography scan showed a round focus with high intensity and contrast enhancement in the cerebellar vermis.

结果 患者 18岁，以复视 2个月就诊，CT显示小脑蚓部有圆形高密度影，组织学检查显示瘤细胞具有多形性，可见黄色瘤样细胞、多核或单核的巨细胞、Rothensal纤维和嗜酸性透明小滴。

Results The small regenerating fibers, central location of nucelus and basophilia endochylema were observed under HE stain both in the patients with DMD and PM. Anachromasis of antiNCAM monoclonal immunohistochemistry stain was found in the regenerating muscle fibers. Positive Ezrin expression was also detected in the regenerating fibers. However, this expression tapered gradually as the mature process of skeletal muscle. The expression of Ezrin was negative in the mature fibers.

结果 DMD、PM患者被检肌HE染色所见再生肌纤维直径较小、核位于中央、胞浆嗜碱性；NCAM染色再生肌纤维深染；再生肌纤维Ezrin呈阳性表达，伴随肌纤维成熟Ezrin表达逐渐减弱，成熟肌纤维无Ezrin表达；成肌细胞Ezrin呈阳性表达。

N perifocal tissue intracerebral hemorrhage there were rarefaction neuron,cell spaces augmentation,cell diminution,distinct demarcation of cell membrane and surrounding,and we discovered a lot of degeneration and necrosis nerve cells,cell body collapsed,pycnosis anachromasis,nucleoli disappeared. In EPO group we discovered that center area of hemorrhage shinked,nerve cells of degeneration and necrosis decreased in perifocal tissue,majority cells morphous were normal and pathological changes were light.

CH对照组在术后皮层出血中心无神经元，仅见少量胶质细胞，细胞间质空泡样改变；出血边缘区神经元稀疏，细胞间隙增大，细胞缩小，胞膜与周围分界清楚，并可见大量变性及坏死的神经细胞，表现为胞体皱缩，核固缩深染，核仁消失。rhEPO治疗组出血中心区变小，边缘区神经细胞变性坏死减少，多数存活细胞形态相对正常，病变较轻。

Three kinds of small molecular copper and zinc superoxide dismutase mimics were synthesized with N, N-bis (benzimidazol-2-ylmethyl) amine (N3), N, N-bis (benzimidazol-2-ylmethyl) methylamine(MN3) and N,N-bis (benzimidazol-2-ylmethyl) benzylamine(BN3) as ligands. The com-plexes were characterized by UV, IR and element analysis and the structures were proposed.

模拟铜一锌超氧化物歧化酶的活性中心，以二(2-苯并咪唑)丙烷为桥、二(2-苯并咪唑亚甲基)胺(N3)、二(2-苯并咪唑亚甲基)甲胺(MN3)及二(2-苯并咪唑亚甲基)苄胺(BN3)为配体合成了3种异双核的小分子模型化合物，并进行了紫外、红外表征及元素分析，推测了可能的结构。

The Square is a favorite haunt of lunchtime office workers, soapbox orators and protest marchers bewailing grievance ranging from visits by nuclear ships to stingy kindergarten funding.

该广场是上班族最喜爱的就餐场地，在这里，也常常可以见到街头演说者和抗议游行者。他们可以在此尽情倾诉大至因核舰艇来访小到因幼儿园经费严重不足所引起的悲伤和怨恨。
