The results indicated that chromosome counting was the most reliable and precise method, however, it was cumbersome and required skilled cytological techniques; The chromocenter size, heterochromatin number, chroloplast number of guard cell and certain plant morphological characteristics are simple and practical methods for ploidydetermination but with some shortages.

结果表明：对体细胞染色体的直接计数法是最可靠的方法，但费时、难度大；叶片气孔大小与倍性无显著相关性；保卫细胞叶绿体数目、体细胞染色中心大小以及异染色质个数与黄瓜倍性密切相关，是简单、快速而有效的倍性鉴定方法；植株的形态学观察也能间接确定植株倍性，但鉴定时期偏晚，精确性较差。

Objective: Effect of plant Coleus Forskohlii active monomer ISOF and CF-E on ALI in vitro was studied. Moreover, the mechanism about them was investigated primarily.

目的：从细胞与分子水平上研究滇产毛喉鞘蕊花提取的单体异佛司可林及有效部位(CF-E，主要为佛司可林的类似物)抗急性肺损伤的作用，初步探讨其作用机制。

Immunofluorescence microscopy may be used to follow the movement of two proteins from different cells following fusion of the cells to form a hybrid heterokaryon.

免疫荧光显微术可用来观察两种细胞融合后形成的杂交异核体中来源不同的两种蛋白质的运动。

The different DNA heteroploid type from one flank demonstrate the role of 〓 gene suppress the prolieration of malignant tumor.

基因mRNA表达阳性或阴性者，对应不同的骨肉瘤DNA异倍体类型，从一个侧面显示出〓基因的抑制恶性肿瘤细胞增殖的作用。

Rat model of cryopreserved aortic and pulmonary valved homograft heterotopic transplantation was established to observe the changes of humoral and cellular immunological response and pathological changes of implanted homografts.

方 法 通过低温保存的大鼠同种异体带瓣主动脉和肺动脉异位移植的动物模型，观察同种移植后宿主体液和细胞免疫指标的变化，以及移植物的病理改变。

Hyperkeratosis lenticularis perstans is a rare keratoid dermatosis and CD4 - positive T cell - mediated immune reaction may play an important role in the pathogenesis of this disease.

持久性豆状角化过度症是一种临床少见的角化性皮肤病，CD4＋T细胞介导的免疫反应在HLP的发病中可能起着重要的作用，异维A酸口服及外用治疗该病有效。

Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

子宫内膜癌组织DC超微结构特征如下：细胞形态不规则，与正常子宫内膜组织DC相比，胞膜较光滑，胞膜表面树突状胞浆突起显著减少，部分突起呈粗短状；胞质中线粒体相对少，圆形而电子密度高的初级溶酶体和不规则形且电子密度高低不一的次级溶酶体多见；高尔基体、粗面内质网、核糖体丰富；含微量絮状电子致密物的胞饮小泡显著减少；胞质中可见形态特殊的颗粒，该颗粒外周膜包裹，略呈圆形，中间部位稍弯曲，如耳机状，颗粒中由高电子致密物居于一侧，而另一侧则呈透亮状；胞核显著减小，居于胞质一侧，常呈肾形或马蹄形，核内常染色质较少，异染色质多边集于核膜下。

Our analysis shows that pre-existing -cells, rather than pluripotent stem cells, are the major source of new -cells during adult life and after pancreatectomy in mice.

乍看起来，这对干细胞疗法研究似乎是不利的，但它却突出反映了也许可采取某种措施让原位分异的b-细胞自己复制的可能性。

And phototrophic microalgae Pavlova viridis with high level of EPA and DHA were fused by chemical cell fusion technique, and a fused strain of mixotrophic microalgae with high level of EPA and DHA and fast growing rate was selected.

利用细胞融合技术，将富含EPA和DHA的自养微藻绿色巴夫藻和生长迅速的异养微藻四鞭藻相融合，并筛选出兼养的融合藻株。

Comparing with phototrophic culture and heterotrophic culture, mixotrophic culture can't influence the inducement synthesizing of pigment but improve the cell concentration of Spirulina, so mixotrophic culture has the potential and particular value in large scale culture. But mixotrophic culture has't come true in commercial production up to the present, it is very important to study the high cell-density mixotrophic culture of Spirulina.

混合营养培养与光合自养及异养培养相比，既可提高微藻细胞密度，又不影响色素等光诱导产物的合成，在大规模培养中具有独特的优势，但至今微藻混合营养培养还没有在商业生产上实现，因此开展螺旋藻高密度混合营养培养工艺的研究显得尤为重要。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
