A strain HH407 which could production cold-active alkaline protease, was isolated from the sea area of Lianyungang. Then, the identification and physiological characterization of the strain HH407 were studied. The results showed that the strain HH407 was gram negative, rod shaped, aerobic, with a single polar flagellum, neither endospore nor capsule formed, about 0.4~0.7 μm×1.0~1.8 μm in size. The colony on screening medium were circular, yellow color, smooth, translucent, convex with regular edges.

Injury to the corticospinal tract, which has facilatory influence on motor neurons in the spinal cord, causes the "negative" manifestations including muscle weakness, fatigability, and decreased dexterity (Rossi, 1994). These features are the major determinant of motor disability associated with upper motor neuron lesions.

痉挛在极易影响运动神经元的脊髓灰质损伤中带来的阴性效应包括肌肉无力、易疲劳、灵巧性下降，这些特征成为与上运动神经元损伤并发的运动残疾的主要决定因素。

Prepare 131I-labbelled anti-CD20 monoclonal antibody using lodogen iodine labelling;(2)Measure the immunity activation of labbelled antibody by means of both cell combine analysis and LDH cytotoxicity detection kit;(3)Evaluate the injury rate of tumor exposed to 131I-chimeric anti-CD20 monoclonal antibody in vitro. The MTT method and the experiment of cell growth control are used;(4)Record the apotosis of Daudi cell using gelose electrophoresis;(5)Learn the inhibition effect of radioactive medication on the marrow. Radiohnmunoimages are taken on various intervals after injection of the labeled antibodies to the nude mice. The distribution of radioactive medication, I31l-labeled antibodies, in the marrow tissue indicates the inhibition effect. Here a B cell non-hodgkin lymphoma model in nude mice is established by us;(6)28-day observation are done in 3 groups of nude mice model.

(1) 用lodogen标记法制备131I-国产人鼠嵌合抗CD20单抗；(2)采用细胞结合分析法和乳酸脱氢酶法细胞杀伤性实验测定131I标记后国产人鼠嵌合抗CD20单抗与靶细胞的免疫活和利结合能力；(3) MTT法和细胞生长抑制实验测定131I-国产人鼠嵌合抗CD20单抗的体外杀瘤活性；(4)用琼脂糖凝胶电泳法研究131I-国产人鼠嵌合抗CD20单抗致Daudi细胞凋亡；(5)建立荷人B细胞淋巴瘤移植瘤裸鼠模型，应用γ计数法检测注射到荷瘤裸鼠体内的131I-国产人鼠嵌合抗CD20单抗的组织分布情况，明确其靶向性；(6)将荷瘤裸鼠分3组进行放射免疫治疗，分别为阴性对照组、131I-国产人鼠嵌合抗CD20单抗组、国产人鼠嵌合抗CD20单抗组。

The results showed that all of the four McAbs against core glycolipid of bacterial lipopolysaccharides(anti-CGL McAbs) were cross-reactive with various type of lipopolysaccharides of Gram-negative bacteria.

常见的革兰氏阴性菌及其LPS均有较强的抑制EL3和3H4结合抗原的作用，EL1和EL2的结合抗原反应也可明显被E。

It was found that there were some differences between the amplified bands of Liquidambar formosana which grew in the place of the altitudes from 100 m to 300 m and in the place of the higher altitudes from 400 m to 700 m, while there was no obvious difference among the amplified bands of Liquidambar formosana's samples (3 samples were from shade conditions and 3 from sunlight conditions) which were from the same altitude (710 m).

结果发现：生长於海拔100~300 m的枫香的扩增谱带与生长於高海拔(400~700 m)的略有差异，而在相同海拔(710 m)的3个阴性条件样品和3个阳性条件样品间，其扩增谱带没有明显差异。

Objective :To assess the overall value of lobulation sign and deep lobulation sign in the differential diagnosis of peripheral lung cancer and pulmonary tuberculoma in CT images.Methods : Firstly , articles about CT differential diagnosis between pulmonary tuberculoma and peripheral lung cancer were selected ,which were published in the period(from January 1990 to December 2008),and useful data were extracted.Then Meta-analysis was done using Meta-disc software,and SDOR value calculated.

方法搜集1990年1月至2008年12月国内外公然发表的关于四周型肺癌与肺结核球CT鉴别诊断的文献，对文献进行筛选，应用Meta-disc软件对符合条件的原始研究进行质量评估、异质性检验，计算阳性似然比、阴性似然比和诊断比值比，最后汇总敏感性和特异性，绘制SROC曲线并计算曲线下面积来综合评价分叶征及深分叶征在CT检查中对于四周型肺癌与结核球鉴别诊断的价值，进行敏感性和特异性分析。

Specifically, by analyzing a set of metazoan species we observed a striking negative correlation of genomically encoded tyrosine content with biological complexity (as measured by the number of cell types in each organism).

尤其是，通过分析一系列多细胞物种，我们发现一个显著的阴性调节关系，即生物的复杂体系中酪氨酸的遗传性编码（通过检测每个物种中细胞类型的数目）。
