最近,我们建立了两个实验系统用来检测潜在的致突变剂或致癌剂。第一个系统是改良的宿主培养法;第二个系统是离体激活法。本文将报道环磷酰胺(cyclophosphamide,CPP)在这两个系统中诱发一个新的遗传标记——抗白喉毒素突变型(diphtheria toxin resistant
Recently, we established two experimental systems to detect potential mutagens or carcinogens. The first system is the modified host culture method; the second system is the ex vivo activation method. This article will report that cyclophosphamide (CPP) induces a new genetic marker in these two systems - diphtheria toxin resistant (diphtheria toxin resistant)
