线虫 Caenorhabditis elegans在甲基磺酸乙酯(EMS)中的毒性实验

基于C．elegans这种非寄生线虫,在生物遗传变异研究中的重要性与必要性,同时EMS(甲基磺酸乙酯)这种生态毒物,常用来作为生物实验中的诱变试剂,二者常常被同时选择作为生物基因遗传领域研究的对象。为定量了解EMS对线虫C．elegans的毒性作用,设计本实验,通过线虫的培养、线虫在EMS溶液中24h暴露、实验结果观察和分析这三个步骤,经过反复实验,摸索实验条件,进行浓度优化,从大量的数据汇总得到了其LC50的数值。为进一步对C．elegans的生物、生态、基因、遗传研究提供了良好的基础。也为通过线虫的生物理解来破解我们人类对自己物种的生物理解做前期的工作。

Ecotoxicology test of C.elegans in EMS

C.elegans is an important domesticated nematode worm with regard to biological inheritance and variation, and EMS is an important chemical mutagens. Both are often used in the research of biological inheritance and gene. In order to learn the biotoxicological relationship of quantity between C. elegans and EMS, a test was designed and conducted, including: egg - preparation, exposure in EMS, and analyse of data. The value of half lethal concentration (LC50) was abtained from the rich experiment data.
