Abstract

The mutagenic actin of cyclophosphane (CP) on the bacterium S. typhimurium TA 1950 in host-mediated assay (mice) was investigated. The mutagenic effect of CP depended on the dose. Administration of carbon tetrachloride (CCl4) to the animals modified the level of the mutagenic effect of CP. The direction of the modification depended on the time elapsed between the introduction of CCl4 and CP. The use of adrenalectomized animals as the mediator led to an increase in the frequency of mutations induced by CP in indicator bacteria.

环磷酰胺对细菌诱变作用的宿主实验研究。
在宿主介导实验(小鼠)中研究了环磷酰胺(CP)对鼠伤寒沙门氏菌TA 1950的致突变性。CP的致突变作用与剂量有关。四氯化碳(CCl4)对动物的诱变作用发生了改变,改变的方向取决于引入CCl4和CP之间的时间间隔。使用肾上腺切除的动物作为介质导致指示菌中CP诱导的突变频率增加。
