The result showed that there was no expression in the normal control group and an apparent expression of ERK1/2 and Elk in the asthma group. A rather dense expressing of ERK1/2 was at bronchiole and mucous membrane, sub mucous membrane, smooth muscle, cytoplasm and nuclei of the out layer of the smooth muscle cell and an expression of positive fiber at submucous membrane.

结果发现正常肺内没有发现ERK1/2和Elk的表达，而哮喘时肺内有明显的ERK1/2和Elk表达，ERK1/2较密集表达在小支气管和细支气管的粘膜层、粘膜下层、平滑肌层和平滑肌外层细胞的胞浆和胞核中，也可见粘膜下层有阳性纤维表达。

The antibodies were purified and the purity and specificity were identified by SDS-PAGE and Western-blot,respectively.Lung tissues from five pigs with PRRS were tested with the established method,which clearly demonstrated the abundant presence of viral antigens in the cytoplasm of alveolar macrophages,and to less extent in alveolar and bronchiole epithelial cells.

SDS-PAGE和Western-blotting检测结果表明，制得的兔抗PRRSV IgG纯度较高，具有良好的特异性，可用于原位检测病猪肺组织中PRRSV抗原的分布；Envision法的检测结果显示，PRRSV抗原的阳性表达产物主要出现在肺巨噬细胞胞浆内，其次为肺泡上皮细胞和细支气管黏膜上皮细胞；通过对5份经RT-PCR检测确认的PRRS病猪肺组织进行检测，均有较高的阳性细胞表达，平均阳性细胞率为46.5%。

Surfactant is produced by alveolar type II cells, stored intracellularly in organelles known as lamellar bodies, and secreted by exocytosis.

肺表面活性物质由肺泡Ⅱ型细胞生成，储存于细胞内的一些细胞器中，由胞外排泌形式分泌。

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。

The MIP-1β mRNA expression in squama cell cancer and adenocarcinoma were significant higher than which in bronchus-alveolus cell cancer without significant difference between each other.

在肺鳞癌和腺癌的大多数癌细胞胞浆中有MIP-1β蛋白表达，在支气管肺泡细胞癌无明显表达；MIP-1β蛋白表达阳性率在腺癌和鳞癌无显著差异（69.7%比58.6%）。

Methods］The application of AFLP in severalpathogens(such as Legionella pneumophila, Flavobacterium, Aeromonas, Clostridium,Bacillus, Acinetobacter, Pseudomonas, Vibrio, Helicobacter pylori and Group AStreptococcal)was reviewed and especially compared with other molecular epidemiologicalmethods.［Results］AFLP shares many characteristics with other genomic fingerprintingmethods.

方法］对近年来AFLP技术在几种病原菌（嗜肺军团菌、黄杆菌属、气单胞菌属、梭状杆菌属、芽胞杆菌属、不动杆菌属、假单胞菌属、弧菌属、幽门螺杆菌和A组链球菌）的应用进行综述，并与其它分子流行病学方法进行比较。

The range of organisms found is very wide and includes bacteria (Pseudomonas M. tuberculosis, E. coli), fungi (Aspergillus, Monilia, Cryptococcus). Viruses (Cytomegalo-Virus. Herpes zoster) and Pneumocystis carinii.

致病微生物的范围很广泛，包括细菌(假单胞菌属、结核杆菌，大肠杆菌)，真菌(曲霉属、念珠菌属、隐球菌属)，病毒及卡氏肺囊虫。

Methods Acanthamoeba polyphaga and Legionella pneumophila were co-cultured under laboratory condition. At consecutive time points during the culture, smears of the cultured products were made on glass slides for staining purposes. Different types of stainings including Gram′s staining, Gimenez staining, Giemsa staining and immunofluorescence were used to determine the best method for the identification of amoebal pathogens.

方法嗜肺军团菌与多噬棘阿米巴共培养，取不同时点的共培养物制作涂片，采用革兰氏染色、吉曼尼兹染色、姬姆萨染色、免疫荧光染色等多种方法，用光学显微镜及荧光显微镜观察鉴别阿米巴滋养体与其胞内嗜肺军团菌，并比较这些染色方法的效果。

Purpose To study the change of lung function before and after therapy in infant respiratory syncytial virus pneumonia.

目的 探讨婴幼儿呼吸道合胞病毒肺炎治疗前后肺功能的变化。

Objective To observe the dynamics of pulmonary function in infants with respiratory syncytial virus bronchiolitis.

目的 观察婴儿呼吸道合胞病毒毛细支气管炎的肺功能动态变化情况并探讨其临床意义。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
