介紹了傳染性海綿狀腦病的種類、特點和病原體，以及牛海綿狀腦病（ bse ）的病徵及感染途徑，並根據大量實驗研究結果對牛海綿狀腦病與人海綿狀腦病之間的關系進行了綜述。This kind of cow leather is bigger and has better tenacity than that of the baby cow, but less tamed. its quality is between the baby cow and the adult cow
此類牛皮比牡牛大且堅固，但是較不柔順，品質亦介於牡牛和成牛之間。This expression vector plbcas - hsa - lgl has the following advantages : i ) the 1. 7kb promoter is able to drive cell - specific and hormone - dependent expression ; ii ) the inclusion of intron - 1 can increase expression level of fusion genes ; iii ) the 5 ' utr of bovine p - casein mrna may have a positive role in both transcriptional and post - transcriptional regulation ; iv ) the gfp gene make the selection of positive clone among embryos possible ; v ) the gfp gene can be easily excised via cre - mediated recombination between the two loxp sites after the expression vector has been integrated into chromosome ; vi ) the two incompatible lox sites, loxp and lox2272, would facilitate cre - recombinase mediated cassette exchange ( rmce ), which in theory will leading to develop a technology of site - specific gene expression in animal mammary glands
該載體的特點是：具有可以調控外源基因在乳腺中特異表達的牛-酪蛋白基因5 `端側翼區和包括第一外顯子及內含子在內的5 `端調控區；將人血清白蛋白cdna準確地置於牛-酪蛋白基因第二外顯子中的翻譯起始密碼子atg之後，而且沒有增加額外的序列和使人血清白蛋白cdna移碼；引入標記基因gfp ，便於在胚胎期鑒定陽性胚胎，減少受體；引入cre lox重組系統： （ ? ）標記基因gfp的兩端的兩個loxp位點可以在表達載體整合到基因組后，刪除標記基因； （ ? ）餘下的一個loxp位點可以和前面的lox2272位點組成cre重組酶介導的盒式交換系統。
