Accordingto the difference of HA gene,which is separated 15 stype from H1 to H15;according to difference ofNA gene,which is separated 9 stype from N1 to N9.It is no cross-reaction between different HA orNA,so it is diffcult to detective.

根据流感病毒的血凝素和神经氨酸酶的抗原性差异，可将A型流感病毒分为不同的亚型，A型禽流感病毒的HA已发现16种，NA有9种，不同的H抗原或N抗原之间无交叉反应，给该病的防制带来了极大的困难。

Objective To screen the protective antigen of G.intestinalis and set the foundation for immune reseach of vaccine. Methods The trophozoite antigens were obtained with in vitro culture system of Giardia lamblia Stile. After further separation, purification and activity verification, the antigens were used to immunize the BALB/C mice divided into different groups,then indexes associated with immunity were determined. Through challenge infection, the most protective antigenic component of G.intestinalis were selected based on its anti-infection ability.

目的 筛选蓝氏贾第鞭毛虫的保护性抗原，免疫疫苗的研制奠定基础方法利用已建立的蓝氏贾第鞭毛虫滋养体体外培养系统，获取滋养体抗原，并进步分离、纯化、活性鉴定；然后分组免疫小鼠，检测相关免疫指标；再行攻击感染试验，视其抗感染能力，筛选出保护性强的抗原组分。

We hypothesize that the following mechanisms may be contributable to the help role of NV epitope for weak tumor antigen.

上述结果提示，NV抗原表位具有很强的辅助效应，它能明显增强机体对gp100CTL表位的免疫应答，进一步提高了以gp100为靶抗原疫苗的体内抗瘤效应，使得gp100弱势抗原表位得以优势化。

A double antigens Sandwich Enzymelinked Immunosor-bent Assay( DAgS -ELISA)have been developed under the basis o f higher titer and freeze dried production conjugate of Brucella antigen with horseradish peroxidase. Serumsamples formdiagnosed patients of Brucellosis and sheep,cattl e,swine infected with Bru-cella as well as normal men and those a nimals in laboratory detected throu gh DAgS -ELISA,SAT and RBPT tests.

方法在制备高滴度布氏菌抗原辣根过氧化物酶结合物及其冻干制品基础上，应用酶联免疫吸附双抗原夹心法即双抗原夹心酶联免疫吸附试验、试管凝集试验及虎红平板凝集试验对从山西省布氏菌病疫区收集的布氏菌病患者、布氏菌感染羊、牛、猪以及健康人、羊、牛、猪共计290份血清进行对比检测。

The assay shows abnormality in 63 of 118 cases (53.4%) of G-I tract cancer, 28 of 116 cases (24.14%) of Gyn. cancer and 13 of 37 cases (35.1%) in other organ's neogrowths.Raised serum levels of CEA occur in many non-colonic cancers.

其中之消化道肿瘤有118例，63例血清癌胚胎抗原测值，呈异常升高佔53.39%； 116例女性生殖器官肿瘤中，血清胚胎抗原测值超过3.5ng/ml的，有28例佔24.14%： 37例其他部位肿瘤患者中，有35.14%（13例）血清癌胚胎抗原测值，大於3.5ng/ml。

Also studied was aza Diels-Alder reaction catalyzed by polyclonal antibody. The bicyclic [2, 2, 2] heptene and the aimed immunogen were synthesized via the key intermolecular asymmetric aza Diels-Alder reaction. Then four polyclonal antibodies were obtained by immunizing rabbit.

在研究多克隆抗体催化氮杂Diels-Alder反应中，通过分子间不对称氮杂Diels—Alder反应为关键反应合成了双环[2，2，2]庚烯类半抗原和目标抗原；用目标抗原免疫动物兔后得到了4株多克隆抗体，经动力学测试表明：多抗Aza-Bsa-3#能催化氮杂Diels—Alder反应的进行。

The experiments may contribute not only to investigating the mechanism of interaction between ldiotype and anti -idiotype T cells by which immune network are up-regulated, but also to analysing the suppressive effect of anti -idiotypic T cell or antibodies against the antigens on the activated T cells in the allo-responsiveness.

本课题选用小鼠耳后心肌移植模型，用同种抗原特异的活化T淋巴细胞免疫同系小鼠的方法，诱导免疫小鼠同种心肌移植物存活时间的延长，以此探讨免疫网络中独特型-抗独特型相互作用机理，着重分析在同种抗原诱导的免疫应答中，抗独特型T细胞和抗活化T淋巴细胞抗原抗体对同种免疫反应的抑制作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
