In this paper the thymus DNA of calf and the pBs plasmid are the main objects of our studies in ultraweak luminescence. By means of PIAS(Photon-counting image acquisition), ultraweak luminescence detector and Lambda Bio 40 of UV/VIS spectrophotometer, we studied the UL of DNA induced by the three oxygen free radicals: singlet oxygen Oa, hydroxy radical and superoxide anion(O2 ). We found that the OH can greatly increase the UL intensity of DNA.

本论文以小牛胸腺DNA和质粒pBs为实验材料，利用光子图像探测系统(Photon-counting image acquistion，PIAS)、微弱发光测量仪和UV／VIS分光光度计和生物统计学的成组比较法原理对单线态氧(~1O_2)、羟自由基、超氧阴离子(O_2~-)三种氧自由基诱导DNA超弱发光的变化过程进行了研究，结果发现这三种氧自由基中·OH能诱导DNA的超弱发光发生显著的增强变化，而其他两种氧自由基对DNA的超弱发光并无显著诱导作用。
