objective: to evaluate the diagnosis and prognosis value of serum prostate specific antigen and prostate specific antigen density in patients with prostatic adenocarcinoma.

目的：探讨血清前列腺特异抗原、前列腺特异抗原密度在前列腺癌诊断及预后判定中的价值。

Results Four hybridoma cell lines stably secreting McAbs against sporozoites were obtained: Easp-3G3 and Easp-5G10 belonging to IgG1, Easp-3H6 belonging to IgG2b, Easp-5H4 belonging to IgG2a. All four McAbs bound with E. acervulina sporozoite protein, but the Easp-5H4 McAb showed cross reactivity with E.

结果 获得4株可稳定分泌单克隆抗体的杂交瘤细胞株，其中Easp-3G3、Easp-5G10为IgG1 类，Easp-3H6为IgG2b 类，Easp-5H4为IgG2a 类。4株单克隆抗体均能与堆型艾美球虫子孢子的抗原蛋白反应，但仅Easp-5H4能与柔嫩艾美球虫子孢子抗原蛋白反应。

The results indicate that antigen Ⅰ/Ⅱ or some of its antigenic determinants is highly conserved among oral Streptococci .

这一结果表明抗原Ⅰ／Ⅱ，至少是其中部分抗原决定簇在口腔链球菌表面粘附器中具有高度保守性。

Methods Calcein-AM stained H9/HIV-1 ⅢB cells were treated with difierent concentrations of PF in the first,second and third trimesters respectively,which was then mixed with MT2 cells and put under fluorescent microscopy for detection of HIV-1-mediated syncytium formation.MT2 cells were treated with cell-free HIV-1 Ⅲ B,and then washed and cultured with different concentrations of PF in the first,second and third trimesters respectively.Furthcrly,the protecting effect of PFs against HIV-1-infected cells Was determined with MTT,viral replication Was evaluated by measurement of the levels of p24 antigen in culture supernatants with ELISA and the inhibition rate Was calculated.

采用荧光染料Calcien-AM标记的H9/HIV-1 ⅢB分别与早、中、晚孕期不同稀释浓度的PF作用后，与MT2细胞混合培养，荧光显微镜下观察合胞体的形成；用游离的HIV-1 ⅢB感染MT2细胞，并分别与早、中、晚孕期不同稀释浓度的PF作用后，用MTT法检测HW-1感染细胞的存活率，用HIV-1 p24抗原试剂盒检测细胞培养上清中p24抗原含量的变化。

The results demonstrated that PNMA5 was expressed in colon cancer and normal testis and brain.

肿瘤抗原是指细胞在癌变过程中出现的新的或过度表达的抗原物质的总称。

Reporter molecules (thiophenol, bipyridine derivates, cyanopyridine derivates) were attached to different immuno-gold colloids, respectively. By means of the specific adsorption between antigen and antibody, a sandwich structure was constructed, in which labelled immuno-gold colloids and antigen covalently bound to substrate specifically capture different antibodies.

以多种不同的标记分子(苯硫酚，联吡啶类分子，氰基吡啶类分子)分别标记多种不同免疫金溶胶，通过抗体抗原之间所具有的特异吸附性，进一步组装"固相抗体-待测抗原-标记免疫金溶胶"多组分三明治复合体系。

Objective To evaluate the potential application of the recombinant multiple epitope antigen in diagnosis of toxoplasmosis.

目的 评价弓形虫多表位基因重组抗原在弓形虫感染诊断中的效果，探索多表位抗原在弓形虫免疫检测中的应用前景。

So there must be some non-specific and transiently expressed factors involved in this process.

这提示TCS免疫之后可引起局部淋巴结细胞短暂地产生出一些非抗原特异性的因子，这些因子可进一步促进在此微环境中的无关抗原的IgE抗体应答。

Objective To detect Trichina spiralls ES antigenic specificity and sensitivity with Dot-ELISA..

目的：将排泄-分泌抗原用于Dot—ELISA免疫学诊断试验，检测其抗原特异性和敏感性。

Objective To screen the mimic antigen epitopes of the triose phosphate isomerase of Schistosoma japonicum Chinese strain and investigate their immunogenicity.
