M. penetrans can stimulate the production of NO and inhibit mouse macrophages prolification, thus it may be an important etiological factor.

穿透支原体的脂质相关膜蛋白能诱导巨噬细胞产生一氧化氮，且能抑制巨噬细胞的增殖，因而可能与其致病性相关。

Most techniques in vivo monitoring the distribution, prolification and migration of transplanted cells. To objectively evaluate curative effect after cells transplantation, most techniques for the study of stem cell transplantation in animal models require histological analysis to determine the fate and migration of cells.

监测活体内移植入细胞的分布、增殖、迁移的方法虽然有多种，但传统方法都需要在离体状态下进行组织学切片分析和鉴定，无法准确地观察植入细胞的生长分化情况，从而难以对干细胞移植术的疗效作出客观评价。

Results M. penetrans LAMPs stimulated mouse macrophages to produce nitric oxide in dose-and time-dependent manner. And M. penetrans LAMPs inhibited cell prolification in mouse macrophages.

结果 穿透支原体脂质相关膜蛋白能以时间和剂量依赖方式刺激小鼠巨噬细胞产生NO，并且对小鼠巨噬细胞的增殖有一定的抑制作用。

To study furderly the activity of CNTF mutant designed by computer molecular modling,this study used the methods of dissociated cultures of chick dorsal root ganglion、TF-1 prolification and the normal mice′weight loss tests.

为了进一步研究我室应用计算机分子模拟设计并表达纯化的睫状神经营养因子突变体蛋白的生物学活性，分别采用鸡胚背根神经节无血清培养法、TF-1细胞增殖法、正常小鼠减重法对其活性进行研究。

Methods M. penetrans was cultured and its LAMPs were extracted. Mouse macrophages were stimulated with M. penetrans LAMPs to analyze the production of nitric oxide. Cell prolification was detected in M. penetrans LAMPs-stimulated mouse macrophages by MTT assay.

用SP-4培养基培养穿透支原体并提取其脂质相关膜蛋白，用提取的脂质相关膜蛋白刺激小鼠巨噬细胞，以ELISA法检测NO的产生，并用MTT法检测其对小鼠巨噬细胞增殖的影响。

We have demonstrated that the expression of protein kinase Cisoform are associated with the development of deciduomata in the pseudopregnant and pregnant rats.

我们过去的研究中已经发现，在蜕膜的形成过程中，不论是在真怀孕或假怀孕大鼠蛋白激酵素C异构体都参与其中蜕膜的形成，因此我们猜测PKC可能参与调节蜕膜细胞的增殖。

Fig.1 SHEE cultured on coverslide, the living cells were growing in single layer with rich cytoplasm, the nuclei were uniform in size with a nucleolus ph ×400 Fig.2 SHEE had a nucleus with ellipse shape, large nucleolus and the cytoplasm contained mitochondria and tonofibrilEM ×10 000 Fig.3 SHEE was spherical in shape, with pseudopods attached on petri dish and abundant villi on cell surface SEM ×5 000 Fig.4 Same as in Fig.3, cell attached on petri dish, appeared stellate or polygonal in shape, with abundant pseudopods and cytoplasmic processes. Protrusive nuclear region in central part of the cell had more micro-villi SEM ×5 000 Fig.5 Chromosomes of SHEE cells belonged to diploidy type Giemsa ×1 000 Fig.6 The SHEE cells of stained in dark brown by Ki67 immunohistochemistry were the proliferative cells Immunohistochemistry ×400 Fig.7 In SHEE cell culture, the nucleus stained red or pink by PI was dead cell, the green nucleus was living cell Fluorescent ×400 Fig.8 The cell labeled by TdT was apoptotic cell in which the chromatin of nucleus condensed in block, a pyknotic nucleus in the upper right conner was seen TdT labeled ×400

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。
