用哺乳类细小病毒 H-1为探针研究紫外线的致死和致突效应,可发现随照射剂量的增加,病毒存活率按对数规律下降,病毒的突变频率线性增加,低剂量紫外线诱导回复突变体的几率较大。用小剂量紫外线诱导宿主细胞,病毒的存活率和突变频率相应提高,同时使紫外线诱导突变体的几率显著提高。 Using mammalian parvovirus H-1 as a probe to study the lethal and mutagenic effects of UV, it was found that with the increase of irradiation dose, the virus survival rate decreased logarithmically, the mutation frequency of the virus increased linearly, and the low-dose UV-induced recovery mutation The greater the chance of body. With small doses of UV-induced host cells, the virus survival rate and mutation frequency increased correspondingly, while the UV-induced mutant significantly increased the chances.
