摘 要:采用Ames试验方法,对硒多糖和亚硒酸钠的抗突变作用进行了研究。试验结果:硒多糖和亚硒酸钠在以硒浓度为0.0336~105μg/皿时,对道诺霉素致突变性的抑制率分别为27.0%~96.3%和20.1%~90.0%;对间接致突物环磷酰胺的抑制率分别为15.4%~51.1%和17.0%~47.6%。硒多糖对叠氮钠致突变的抑制率为1.7%~15.5%。表明硒多糖和亚硒酸钠对道诺霉素致突变性有明显的抑制作用,对环磷酰胺的致突变性有一定抑制作用。而硒多糖对叠氮钠致突变性的抑制作用不明显。The antimutagenic effects of selenium polysaccharide and sodium selenite were investigated with the Ames test. It was shown that, at the dosage of 0.0336-105 μg Se/dish, the mutations induced by a potent mutagen daunomycin were inhibited significantly for 27.0 %-96. 3% and 20. 1%-90. 0% by selenium polysaccharide and sodium selenite, respectively; and the mutations induced by the indirect mutagen cyclophosphamide were inhibited obviously by the two agents for 15. 4 %-51. 1 % and 17. 0 %-47. 6 %.The mutagenesis of sodium azide was suppressed by selenium polysaccharide for 1. 7 % -15. 5 %.
