The anther possesses four microsparangia with its wall composed of four layers: epidermis, endothecium, middle layers and a 2\|nucleate celled tapetum.

绒毡层细胞在发育后期由单核分裂为2 核，多原位解体，为腺质型；但大约有12％小孢子囊的绒毡层在小孢子四分体释放时期进入花药室内，成为变形绒毡层。

However, in SLE patients with leucopenia, the telomere length of MNC was significantly shorter than that of PMN.

然而在白血球减少的红斑性狼疮病人，其周边血液单核细胞终端体长度的确较多形核嗜中性白血球终端体长度显著地短。

Abstract］ AIM:To investigate the role of nuclear factor κB in the induction of iNOS gene by TNFα and LPS in endothelial cells and the effect of antioxidant on the induction of iNOS. METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NFκB in the cell nucleole was detected with electrophoretic mobility shift assay.RESULTS:(1)NO production and iNOS mRNA expression induced by LPS and TNFα was blocked by pyrrolidine dithiocarbamate or N-acetylcysteine.

研究表明内皮细胞激活时iNOS表达的调控主要发生在转录水平。iNOS基因的启动子区域含有多个转录因子的结合位点包括NFκB、AP-1、NF-IL6，Oct-1等［2］，而核因子κB(nuclear factor κB， NFκB)被认为在多种参与炎症反应的蛋白质因子的基因调控中担任重要角色，因而可能是内皮细胞激活的调控中一个重要转录激活因子［2，3］。

In this paper, the male reproductive system of this species was investigated by light microscopy, and electron microscopy, and the tetraploidy embyros of the prawn were induced by heat shock treatment.

本文应用组织学、电子显微镜、细胞遗传学及多倍体诱导技术对日本沼虾雄性生殖系统、染色体及核型、多倍体产生的条件等进行了比较深入的系统研究，对于解决人工授精难题和培育出品质优良的养殖品系具有重要意义。

Meanwhile, the number of nNOS-IR positive neurons in caudatum increased as compared to the normal group.

结果MPTP致模型小鼠在黑质致密部多巴胺能神经元损伤后，运动协调能力下降，同时在尾核的nNOS免疫反应阳性神经元细胞数较正常组增多。

According to our knowledge, there have been a few reports on this field, but none was related to use meiotic inhibited agents for promoting oocyte developmental competence.

有关这方面的研究报道还不多，尤其在以核成熟抑制剂对卵母细胞产生抑制，并观察其后的胚胎发育活性方面。

Analysis of mitochondrial DNA composition of the panda-rabit cloned embryos found that mitochondria from both panda somatic cells and rabbit ooplasm co-existed in early blastocyst, but mitochondria from rabbit ooplasm decreased and those from panda donor cells dominated in early fetuses after implantation.

结果显示，应用卵裂球电融合方法可以制作一系列的多倍体胚胎；小鼠囊胚的形成与胚胎中的细胞数目无直接关系，卵裂球的电融合和染色体数目的增加不会改变胚胎的发育进程；而胚胎细胞中的核／质比可能是控制胚胎囊胚化的一个重要因素。

The effects of acetylcholine and atropine on the electric activities of neurons of nucleus parafascicularis thalami were observed in anesthetized rats with multimicropiptte technique and iontophoresis.

在30只大鼠上，用多管微电极细胞外记录和离子微电泳方法，观察了乙酰胆碱和阿托品对丘脑束旁核神经元电活动的影响。

Here is another view of a peripheral blood smear in a patient with CML. Often, the numbers of basophils and eosinophils, as well as bands and more immature myeloid cells are increased.

慢性髓性白血病外周血涂片，常见较多嗜碱性粒细胞和嗜酸性粒细胞，也有较多的杆状核嗜中性粒细胞和不成熟的髓细胞。

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。
