The carcinogenic mechanism of nitrosamine is that it may cause the changes of tumor related gene and suppressor gene in esophageal epithelisl cells.

其致癌机制研究显示，亚硝胺可引起食管上皮细胞相关癌基因抑癌基因发生改变，大大促进癌变。

Pumpkin can prevent and cure diabetes, accelerate secretion of insulin, eliminate mutagenic effect of nitrosamine which is a kind of carcinogenic substances, prevent cancer and also can promote regenerative power of cells of liver and kidney.

This experiment showed that there was an proliferative changing at the cell of nodose ganglion of the sensory nerve fiber in lung when asthma attacked and suggested that the changing of growth and excitability of lung sensory nerve may well result from the change of neuron.

本实验表明哮喘时肺内感觉神经纤维的胞体所在部位颈静脉节的细胞也发生了增生性改变，提示肺内感觉神经纤维的生长和兴奋性变化可能是源于神经元胞体的变化。

They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

Polymorphonuclear neutrophil is the main effector cell in the process of inflammatory, for which it is the first line of defense system that the host antagonizes inflammatory or nonself matter, and plays an important role in occurrence, development and turnover of inflammation.

中性粒细胞(polymorphonuclear neutrophil，PMN)是炎症过程中重要的效应细胞，是宿主对抗感染的第一道防线，在炎症的发生、发展、转归中起着关键的作用。

The significant changes were obseved in the morphology,size,number and the degree of development of nuclei,nucleole,mitochondrial and chloroplast of apicalmeristem cell.

在这期间茎端细胞内核仁、线粒体、叶绿体等的形态、大小、数量、发育程度等发生明显变化。

This dissertation is divided into three parts. The first part is studies on calcium distribution changes during spermatogenesis, epididymal maturation, capacitation, acrosome reaction, oocyte maturation and egg fertilization using in situ precipitation by potassium antimonate and Ca〓 fluorescent probes at electron and light microscope levels. The main results are: 1 Ca〓 was probably involved in the condensing process of nucleoplasm during spermatogenesis.

本论文分为三个部分，第一部分主要是采用焦锑酸钾原位定钙法和Ca〓荧光染料在电镜和光镜水平对哺乳动物精子发生、附睾成熟、获能、顶体反应及卵母细胞成熟和卵受精过程中Ca〓的分布变化规律进行了系统的研究。

Apoptosis was induced by hypoxia injury in the NSCs, the amount of apoptosis in the group treated with NYA serum was significantly lower than that of model group and normal-serum group. It suggested that NYA serum can inhibit the NSCs apoptosis.

培养神经干细胞缺氧损伤后发生凋亡，脑溢安血清组凋亡细胞数显著低于模型组和正常血清组，提示脑溢安能减少缺氧损伤神经干细胞凋亡。
