我组继摸索人体外周血简易测定技术后,又在该测定方法的基础上进行了部分的改进,获得了大鼠尾血染色体制备的成功。此法能进行自身对照,并与其他指标可同时观察与评价,为毒理学研究提供一个可动态的观察。现介绍如下。 Following the exploration of a simple measurement technique for peripheral blood in humans, the group also made some improvements on the basis of the assay, and obtained the success of chromosome preparation in rat tail blood. This method can self-control, and can be observed and evaluated simultaneously with other indicators, providing a dynamic observation for toxicological research. The introduction is as follows.
