Objective To investigate the expression of vascular endothelial cell growth factor,basic fibroblast growth factor, transforming growth factorβ1(TGF β1)and tumor derived adhesion factor in laryngopharyngeal malignant melanoma and its relation to neovasculariztion and prognosis of the disease.

目的研究血管内皮生长因子、碱性成纤维细胞生长因子、转化生长因子β1(TGFβ1)及其受体和肿瘤源性粘附因子在咽喉部恶性黑色素瘤中的表达特点，以及它们与肿瘤内微血管密度和病人预后的关系。

Schistosoma japonica antigen cDNA clones were identified by lysogenic expression,flat lyiic method and PCR amplification. All 8 positive clones immunologically screened could be expressed in E- coli in the form of fusion proteins with the molecular weight being about 140 to 150 kDa. The positive cDNA genes were digested by restriction endonuclease EcoRI,then the agarose gel electrophoresis revealed the size of them being 700 to 900 bp.

利用融源表达、平板裂解法和PCR扩增三种不同方法分别对日本血吸虫抗原cDNA基因进行鉴定和分析，8个免疫筛选阳性克隆均能在大肠杆菌中以融合蛋白的形式表达，表达蛋白分子量为140～150kDa，抗原cDNA基因经限制性内切酶EcoRI酶解后，琼脂糖凝胶电泳显示其大小为700～900bp，PCR能扩增出特异性条带。

Intra-articular injections, medial branch nerve blocks, and neurolysis of medial branch nerves have been described in managing chronic neck pain of facet joint origin.

Another method that has been proposed to identify S.aureus from nonclinical sources employs an immunoenzymatic assay using a monoclonal antibody assay using a monoclonal antibody prepared against S.aureus endo-β-acetyl-glucosaminidase, an enzyme produced by all isolates of this species.

另一种方法，提出了确定非临床源金黄色葡萄球菌从员工的免疫酶检测用单克隆抗体检测用单克隆抗体制备对金黄色葡萄球菌内切β-乙酰氨基葡萄糖苷酶，这种酶产生的所有分离这一物种。

There are a tens of flash orthographical shadow photograph points which are the main test equipments in the ballistic tange of the flight line.

实验表明，同一照相站两个火花闪光源内光的不同步时间约可在3μs，这给测量结果带来了不容忽视的误差。因而，改善正交闪光阴影照相的同步性能是十分重要的课题。

For biogenic VOC modeling, emission factors, vegetation biomass and leaf area index were determined for 37 vegetation types. The widely accepted algorithm of Guenther et al.(1993), describing the relationship between light, temperature and the VOC emissions, was adopted. A new canopy model was established to simulate photosynthetically active radiation and leaf temperature within the canopy.

对于VOC生态源模式，确定了37种植被的VOC排放因子、生物量和叶面积指数；采用了相对成熟的关于VOC排放强度和光合有效辐射、叶面温度的依赖关系；建立了一个新的植被冠层模式以模拟冠层内PAR和叶面温度的变化。

Methods Twenty-four cases with non-pituitary lesions in sphenoidal sinus and sellar area were analyzed . Eighteen cases were benign, including 7 sphenoidal sinus cyst, 6 craniopharyngioma, 2 chordoma, 1 nasal polyp extending into the sella,1 neuronoma in sella,and 1 pinealoma.

总结分析24例蝶窦鞍区非垂体源性占位性病变，其中良性18例，包括蝶窦囊肿7例、颅咽管瘤6例、脊索瘤2例，鼻息肉伴鼻硬结杆菌感染侵犯蝶窦鞍区、蝶鞍神经鞘瘤、鞍内异位松果体瘤各1例。

Autotetraploid rice IR36-4X was treated with ion implantation of low energy nitrogen ion beams and a polyembryonic seedling mutant IR36-Shuang was identified in M2 generation.

以低能氮离子束为诱变源，对同源四倍体水稻品系&IR36-4X&进行离子注入，在其第2代群体内筛选得到了1株具有多胚苗性状特征的突变株（IR36-双）。

In the present study, the autotetraploid rice IR36-4X was treated with ion implantation technique by nitrogen ion beams and a polyembryonic seedling mutant (named as the IR36-Shuang) was identified in M2 generation. The mutant line was systematically investigated about the location of seedling in polyembryonic seedling, and the cytological initiation of the additional embryo in the 1R36-Shuang was observed and determined.

以低能氮离子束为诱变源，通过对同源四倍体水稻品系&IR36-4X&进行离子注入后在其第2代群体内筛选得到了1株具有多胚苗性状特征的突变株（IR36-双），对该突变株后代的多胚苗形态特征及其多胚来源进行了研究。
