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.

Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.

取食构树的桑天牛成虫取食量大，存活时间长，产卵量大，遗卵量少，其他3个树种则相反。4树种树皮内总糖和可溶性蛋白含量与桑天牛抗性无关，树皮内可溶性糖含量、总氨基酸和必需氨基酸含量对抗性有一定影响。4树种树皮内水溶性总酚含量和单宁含量差异对成虫取食有较大影响，酚类和单宁等次生物质对桑天牛成虫的忌避作用是导致抗性的主要原因。

Firstly by using volume exclusion chromatography and cation exchange column,sugar molecular-weight distribution and the contents of monosaccharide, disaccharide andtrisaccharide in rice wine were determined. And then by using amino-bonding phasecolumn,the contents of three functional oligosaccharide (isomaltose, panose, isomaltotriose)in shaoxing rice wine of different years and different processes were determined andstudied.

在应用体积排阻色谱柱和钙型阳离子交换柱测定了黄酒样中糖分的分子量分布和单、双、三糖含量的基础上，利用氨基键合相柱对不同年份和不同工艺的绍兴黄酒样中异麦芽糖、潘糖、异麦芽三糖三种功能性低聚糖进行了定量分析研究。

The results showed that Tang-an-kang could respond symptomatically, lower blood-sugar, diminish urinary protein, regulate endogenous creatinine clearance rate and lipid metabolism etc. It was suggested that Tang-an-kang had a good action on improvement lipid metabolism, diminishing urinary protein and renal function protection.

结果表明：糖安康治疗组在改善DN患者临床症状，降低血糖、糖基化血红蛋白及血肌酐，减少尿蛋白及尿白蛋白，调节内生肌酐清除率，降低血与尿β2微球蛋白，调节脂代谢，改善血液流变性等方面，疗效均优于单用西药的对照组，提示糖安康有良好改善糖脂代谢、减少尿蛋白、保护肾功能的作用。

First,through monofactorial experiment,we studied the influences of pH,temperature and substrate concentration on acidic trehalase activity of baker's yeast.

首先通过单因素实验研究了pH值、温度、底物浓度对面包酵母酸性海藻糖酶活性的影响，然后通过正交试验得出了酸性海藻糖酶活性测定的适宜条件：海藻糖浓度1.6%、温度30℃、pH 4.0、酵母菌泥接种量为0.02g/mL。

They are classified based on their backbone of carbon atoms: Trioses have three carbon atoms, tetroses four, pentoses five, hexoses six, and heptoses seven.

单醣按其分子中碳原子的数目分类︰丙糖含3个碳原子，丁糖4个、戊糖5个、己糖6个、庚糖7个。

Consequently,in this study we introduced genes that encode the xylose isomerase and xylulokinase precisely under the control of a strong,constitutive glyceraldehydes-3-phosphate promoter by PCR-mediated overlap extension,which is in charge of xylose assimilation;and also we introduced genes that encode the transaldolase and transketolase precisely under the control of enolase promoter,which is in charge of xylose utilization,then transformed plasmid with the two operons into Z.
