Swine pox, which belongs to the pox disease complex, is caused by two antigenically different poxviruses . 豬痘屬于痘病群,是由兩種抗原上不同的痘病毒引起的。
The results suggested that human hscs can engraft into rat and differentiate into multilineage under certain microenvironment . thus , the human / rat xenograft model may provide a useful and convenient method for assay human hscs in vivo 新生大鼠免疫系統發育不完善,對異種抗原可形成免疫耐受,是很好的研究異種移植的實驗動物,且經濟。
Three types of influenza viruses are recognized : a , b and c . influenza a viruses are further categorized into subtypes on the basis of two surface antigens : haemagglutinin and neuraminidase 流感病毒共分甲乙丙型三種。甲型流感可依據病毒表面的血凝素haemagglutinin ,即h及神經胺酸neuraminidase ,即n兩種抗原類型,再細分為不同的亞型。

A protein substance produced in the blood or tissues in response to a specific antigen , such as a bacterium or a toxin . antibodies destroy or weaken bacteria and neutralize organic poisons , thus forming the basis of immunity 抗體,免疫體血液或組織針對某種抗原如細菌或毒素而產生的蛋白質物質。抗體消滅細菌或削弱其作用,中和有機毒素,因而形成免疫力
On the consideration of these problems and the fact that the rat immune system is not fully developed until birth , we tried to transplant neonatal rat with human hscs to test the possibility of this xenograft model 但此實驗模型操作復雜且實驗周期長,大多數實驗室不具備利用此實驗模型的條件。有研究證明,新生大鼠免疫系統發育不完善,對異種抗原可形成免疫耐受。
The acellular matrix treated by sds or glutaraldehyde should be cleaned by normal saline , or there will be cytotoxicity in it . the results of cell culture and implantation experiment demonstrate the high degree of cytocompatibibity and biocompatibility of this kind of acelluler matrix A半乳糖殘基是豬到人的主要異種抗原,會導致超急性免疫排斥,要實現豬到人的異種移植首先要去除的就是o gal 。
Genetic vaccine is quite different in structure from traditional ones . the experiments show that delivery of genetic material into an animal ' s cells can trigger some synthesiztion of the encoden proteins as well as of antibodies targeted against those proteins 核酸疫苗是將編碼某種抗原蛋白的外源基因插入某種表達載體中并直接導入的動物體內,表達抗原蛋白,并誘導宿主產生對該抗原蛋白免疫應答的革命性的新型疫苗。
In one word , the methods for producing acellulace matrix have not been standardized . in this study , we want to select the best way to produce acellular matrix . we also use immunohistochemical method for detecting the magor heterogenetic antigen a - galactosyl residues ( a - gal ) in acellular matrix 并應用免疫組化的方法檢測脫細胞后基質的主要異種抗原,用種植實驗觀察異種機體對脫細胞生物基質的組織反應倩況,另在其上種植鼠成纖維細胞以觀察脫細胞生物基質的細胞毒性和細胞相容問題。
In this experiment three sperm proeins , sp - 10 . aeg . tmdc - iii . that were cloned and expressed by brist u . k . , immunized on rats for analysing their immunogenicity and the effects on the fertility . then using indirect immuno - fluorescein staining method , the localization of sp - 10 , tmdc - iii and aeg on human , mouse , rabbit , pig , bull sperm was observed under confocomicroscopy . the results as follows : 1 . the rats successfully produced antibody after immunization with antigens sp - 10 , aeg , tmdc - iii respective 本文用英國葛蘭素公司重組構建表達的三種抗原蛋白sp - io , aeg , tmdc -免疫大鼠,通過elisa實驗、免疫熒光組化實驗、交配實驗對它們的免疫原性、在體內的生殖作用、精子表達部位進行了分析,結果如下: 1
