转基因动物作为研究代谢调节、分化、发育中有关基因功能的工具已在各领域发挥了巨大的作用.在新药开发和研究中,因转基因动物的准确、经济、实验次数少和显著缩短实验时间等优点,现已成为一种进行“快速筛选”和药物非临床前安全评价的的手段.本文将对毒理学研究方面常用的转基因小鼠和大鼠进行阐述,旨在更全面的了解其在毒理学研究中的重要作用,为利用转基因技术技术培育应用于毒理学研究方面的转基因小鼠和大鼠的制备提供参考性的依据.%Transgeneie animals play an important role in researches of gene functions related to regulation of metabolism, cell differentiation and growth, etc. In the new drug development and investigation, transgenic animal models have been a useful tool of non-clinic safety evaluation and rapid screening. In this article we will review the commonly used transgenic mice and rats in toxicology, and to briefly discuss the significance of transgenic animals in toxicological studies.
