然后再使用抗生素抗性分析、b-内酰胺酶的酶活测定以及Western blot杂交技术，分析质粒编码的b-内酰胺酶从细胞质到细胞间质的分泌情况。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。

Calpain system is probably the major proteolytic in protein degradation,which plays an important role in myofibrillar protein degradation.

近年的研究表明，calpain是细胞质中主要的蛋白水解酶，在肌原纤维蛋白降解中起着重要的作用。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

The cytoplasm of the tapetum cells of Zhenshan 97A deposited a few Ca(superscript 2+) precipitates at the pollen mother cell stage. At the meiosis stage, there were many large Ca(superscript 2+) precipitates at the inner longitudinal cell wall; there were a layer Ca(superscript 2+) precipitates around the tapetal cells.

珍汕97A绒毡层细胞从花粉母细胞时期开始，细胞质内有少量颗粒状的Ca(上标 2+)沉淀；减数分裂时期，绒毡层细胞的内切向壁表面有大量大颗粒的Ca(上标 2+)沉淀；单核花粉时期绒毡层细胞周围集聚一层Ca(上标 2+)沉淀。

The injury tolerance of cell plasma membrane and the correlative enzymes activities of plasma-membrane protection system in the Ulmus pumila leaves treated by nine concentrations (0.3%, 0.6%, 0.9%. 1.2%, 1.5%, 1.8%, 2.1%, 2.4%, 3.0%) of Na2CO3 and NaHCO3 mixtures were studied in a greenhouse of Northeast Forestry University, Harbin, China.

在东北林业大学育种基地，利用9种浓度(0.3%、06%、0.9%、1.2%、1.5%、1.8%、2.1%、2.4%、3.0%)的Na2CO3和NaHCO3混合液对白榆扦插苗进行胁迫处理，探讨其在盐胁迫下，细胞质膜的伤害程度和质膜保护系统相关酶的活性。
