这些结果具有重要意义，因为多环芳烃二醇环氧化物极易与DNA反应，进而导致变异，因此被视为香烟烟雾中所含多种多环芳烃中最重要的致癌物质。
These results are significant because PAH diol epoxides react readily with DNA, induce mutations, and are considered to be ultimate carcinogens of multiple PAH in cigarette smoke.
有毒的matagenic和致癌物质PAH二醇环氧化合物均来源于多环芳香烃(PAH)，它是导致大多数肺癌的罪魁祸首。
Toxic matagenic and carcinogenic PAH diol epoxides can be derived from PAHS, which are responsible for most cases of lung cancer.
结论炔雌醇环丙孕酮片在多囊卵巢综合征治疗中的应用效果显著，可进行临床推广。
Conclusion Ethinylestradiol cyproterone application in the treatment of polycystic ovary syndrome effect is remarkable, but for clinical promotion.
目的探讨炔雌醇环丙孕酮片在多囊卵巢综合征治疗中的应用效果。
Abstract: ObjeTo investigate the ethinylestradiol cyproterone in application effect in the treatment of polycystic ovary syndrome.
研究认为：“这项结果相当重要，因为多环芳香环氧二醇（PAH diol epoxides）易与DNA反应，引发突变，所以被认为是吸烟产生的众多环芳香烃中最严重的致癌物质。”
"These results are significant because PAH diol epoxides react readily with DNA, induce mutations, and are considered to be ultimate carcinogens of multiple PAH in cigarette smoke, " the study said.
