Objective: To study the effect of two kinds of Equisetum extract on the proliferation, apoptosis and the expression of mutant P53 in smooth muscle cells in early Atherosclerotic rats.

目的：研究木贼正丁醇提取物及提取剩余物对大鼠动脉粥样硬化早期主动脉平滑肌细胞增殖、凋亡及突变型P53表达的影响。

Two kinds of Equisetum extract can regulate the expression of mutant P53 to decrease the proliferation and increase the apoptosis of smooth muscle cells to prevent the occurrence of early atherosclerosis.

两种木贼提取物均可降低突变型P53表达，促进AS早期干滑肌凋亡，抑制其增殖，具有阻断AS早期病变进展的作用。

Results The proliferation index of smooth muscle cells in the two Equisetum extract group were lower than model group but the rate of apoptosis were higher, the expression of mutant P53 were lower than model group too.

结果：木贼正丁醇提取物及提取剩余物预防性给药可降低平滑肌增殖指数，减少突变型P53表达，升高其调亡率。

CD was used to monitor changes of the mutant esterase secondary structure upon heating.

所以对两种酶的热稳定性及变性剂稳定性的研究主要集中在酶活性和三级结构的变化关系上。

Inhibition of chlorophyll synthesis may be caused by etiolation, mutant blocks, or streptomycin

叶绿素合成可以由黄化、突变性阻塞或链霉素而引起。

It was found that there were 36 distinct differences in 184 protein spots. In-gel digestion and liquid chromatography mass spectrometry C LC-MS were made to analyze the protein SSP2801, and Mascot software was applied to identify the protein. The results showed the protein was large subunit of Rubisco, and its content in yellow mutant decreased distinctly, only about 26% of the comparison. Maybe it has relation to etiolation.

切耿其中差异最为明显的SSP2801位点蛋白进行胶内酶切、LC-MS分析，并应用Mascot软件检索鉴定，结果表明该蛋白组分为RUBP羧化酶的大亚基，其在突变体中含量明显减少，仅为对照的26％，表明突变体叶色黄化与RUBP羧化酶大亚基含量减少也有关系。

The results showed that the mutant contained high trehalose content and high cell survival rate kept even after 4 h 18 %vol alcohol treatment (no respiration deficiency existed), which indicated that high trehalose content could protect cells membrane and prevent DNA loss of mitochondria and exosmosis of intracellular materials.

结果表明，中性海藻糖酶缺失突变株细胞海藻糖含量较高，用18 %vol的酒精处理4 h后仍可保持高的细胞存活率，并且无呼吸缺陷型的出现，说明高海藻糖含量可以保护细胞膜，防止线粒体DNA丢失和胞内物质的外渗，与酵母的酒精耐性之间存在一定的关系。

In order to identify the mechanism of melanic mutant of S. exigua, genetic regulation on pupae body color, puparial exuviae, phenoloxidase activity, dopamine andβ-alanine of SEW and SEM were investigated.

本文以SEW和SEM为材料，分别从蛹黑色性状的遗传规律、多酚氧化酶活力、电镜分析、高效液相分析、多巴胺和β-丙氨酸的微量注射及饲喂诱变几个方面进行了研究，以期找出甜菜夜蛾黑化的机理。

Frisson and Vicia hirsute, we found that inactivation of the hurL gene caused failure in inducing nodulation, whereas the same mutant complemented with an intact R.

而经野生型hurL基因互补的同一突变株在这两种植物上的结瘤数均恢复到野生型水平。

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.
