ABSTRACT: Objective To investigate the relation between the apoptosis in splenocyte and the changes of Th1/Th2 balance in serum of menopausal rats.

目的 了解更年期大鼠脾细胞凋亡与辅助性T细胞1(Thelper l， Th1)和辅助性T细胞2(Thelper 2， Th2)型细胞因子的增龄性改变。

Under low temperature condition, fertility restoring, anther developing normally, the tetrads formed after archesporical cell, sporogenous cells and microspore mother cell. Subsequently, microspores were free from the tetrad of fertile anther and formed mature pollen grains, tapetumof the fertile anthers began to disintegrate and disappear at last.

在低温处理条件下，育性恢复，花药发育正常，经过孢原细胞期、造孢细胞期、花粉母细胞期后，可以顺利形成四分体，可育花药的四分体可以释放出小孢子并发育为成熟的花粉粒，同时绒毡层细胞开始解体，最后消失。

The article focuses on the aberrant expression and significances of proto-oncogenes, tumor suppressor genes and genes associated with the proliferation process of gastric cells such as telomerase, transcription factor and cyclooxygenase, etc. These genes, alone or synergically, participate in gastric cancer cell proliferation, resulting in an uncontrolled growth characterized by over-proliferation of decreased apoptosis of gastric cancer cells.

本文着重阐述了与胃癌细胞增殖过程密切相关的端粒酶、核转录因子、环氧化酶等基因以及参与细胞周期调控的原癌基因、抑癌基因的异常表达及临床意义，这些基因或单独作用，或相互协同，参与胃癌细胞的增殖，使肿瘤细胞生长以增殖过多、凋亡过少的失控性生长为特征。

We tested whether inhibitory GABAergic synaptic transmission regulates Xenopus optic tectal cell dendritic arbor development in vivo by expressing a peptide corresponding to an intracellular loop ofthe gamma2 subunit of type A GABA receptors GABA(AR, which is required to anchor GABA receptors to the postsynaptic scaffold.

我们想证明如下设想：抑制性GABA能突触传递是否能调节早蟾视顶盖细胞的树突发育。因为GABA受体的gamma2亚基有一段细胞内的跨膜端序列，这段序列对锚定GABAA受体到突触后膜是必须的，所以我们的主要方法是设计了一段特异性的争对细胞内段的序列，这样就特异性的阻断了单个细胞GABA能的突触传递。

For tumors which have been well sampled and exhibit (1) a microcystic pattern and regions with lobulated cellular masses with intervening, sometimes hyalinized fibrous stroma,(2) an absence of morphologic features enabling any other specific diagnosis in the sex cord-stromal category,(3) an absence of epithelial elements, and (4) an absence of teratomatous or other germ cell elements, we propose the designation microcystic stromal tumor.

我们很好地抽样调查了4例肿瘤，显示：（1）微囊样式和有时插入玻璃样变的纤维间质中的分叶状细胞团区，（2）能造成在性索间质这个大类中其他具体诊断的形态特征缺失，（3）上皮成分缺失，（4）畸胎或其他胚芽细胞成分缺失，我们提议定其名为微囊性间质瘤。

It indicated that when the midbrain reticular formation induced cortical desynchronization through the thalamocortical loop, it simultaneously excitated an inhibitory path which acted on the bodies of dentate granule cells and declined the excitability of granule cells. After the injection of Urethane, the negative correlation between EPSPs and PSs were weakened.

这可能是因为：中脑网状结构上行激励系统通过丘脑-皮层回路使ECoG去同步化时，同时也通过另一途径，即隔-海马连接，激活了作用于齿状回颗粒细胞胞体的抑制性神经通路，使得颗粒细胞兴奋性降低，从而使反应动作电位总和的PS幅值减小。

Apoptosis may be also involved in the pathogenesis of neuronal death induced by this thrombotic ischemic lesion.

血栓性脑缺血损伤中存在细胞凋亡现象及凋亡相关基因Bc1-2、Bax的表达，细胞凋亡也参与了血栓性脑缺血所致的神经细胞死亡过程。

The expression of MMP-3 mRNA of RA was higher than that of controls,and the expression of MMP-3 mRNA of RA in active stage was higher than that of RA in unactive stage, and there were no difference in different genotypes.

RA患者外周血单核细胞MMP-3的mRNA表达水平高于健康对照人群，有显著性差异，活动期RA患者外周血单核细胞MMP-3的mRNA表达水平高于非活动期的患者，有显著性差异。

Results No apparent cytopathic effects could be observed during the first 24 hours of infection with L-form and elementary bodies, but the cytoplasm of some MA104 cells became vacuolated when the L-forms entering into the cells as shown by immunohistochemical staining and PCR.

结果 发现金葡菌L型及滤过的原生小体对细胞致病性降低，细胞不出现明显病变，部分细胞出现空泡样变，免疫组化及金葡菌PCR显示感染细胞内出现金葡菌抗原及DNA。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
