查询词典 carcinogen

Sorbic acid has thrill to people's skin and eyes and sodium benzoate can produce carcinogen when nitrate exist.

The State's attorney general filed suit under Proposition 65 against some of the biggest food companies, including McDonald's, Burger King, KFC, and Frito-Lay, to force them to put warning labels on all French fries and potato chips sold in California because they contain high levels of acrylamide, a known carcinogen.

有致癌物，主要是丙烯酰胺加州首席检察官起诉一些大食品公司包括：麦当劳、Burger King，肯德鸡，和 Frito-Lay，强制要求它们在加州销售的法式油炸和土豆片上贴上警告语：本品含有高浓度丙烯酰胺----一种已知致癌物！

The rapid acetylator would increase the heterocyclic amines from pre-carcinogen to active formation.

随着MTHFR 667 C-＞T的多态基因在基因组中比例升高，其腺瘤复发有下降的趋势，而且饮酒与红烧鱼因素的相对危险度也呈下降趋势。

It is suggested that the metabolism of heterocyclic amines generated from fried fish may be altered by genetic variability of NAT2. The rapid acetylator would increase the heterocyclic amines from pre-carcinogen to active formation.

NAT2多态性与吸烟有交互作用，特别是野生纯合型与吸烟交互作用可使直肠腺瘤复发危险度上升到22.75(95％CI 2.11-244.86，P＝0.007)，其机制可能为NAT2酶可能参与了烟草中产生的多环芳烃致癌物，从而涉及直肠腺瘤发生。

Nevertheless, Smoking could interact with wild type of NAT2 and increase the relative risk of rectal adenoma recurrence significantly. It is suggested that NAT2 might involve the metabolism of pre-carcinogen generating from tobacco and alter the susceptibility of cancer. Meanwhile, the NAT2〓4 alleles encode rapid acetylator of NAT2 would increase the risk of adenoma recurrence among those high-risk people with habit of fried fish intake.

吃红烧鱼因素在NAT2的快速酶中，特别是在野生纯合型中直肠腺瘤复发的相对危险度有增高趋势，提示了NAT2〓4等位基因编码快酶型NAT，可能在红烧鱼产生的杂环胺类化合物中代谢中加速其N-乙酰基化代谢过程，从而加速其代谢为终致癌物而与肠粘膜上皮细胞的DNA产生加成物，损伤其遗传物质。

EB virus is a human B-lymphocyte affinitive Herpesviridae, discovered in 1964 by Epstein and Barr during their research of African children malignant lymphoma, which is now defined as type I carcinogen by International Agency for Research on Cancer.

EB病毒(Epstein-Barr Virus， EBV)属疱疹病毒科，1964年由Epstein和Barr在研究非洲儿童恶性淋巴瘤时发现的一种感染人类B淋巴细胞的疱疹病毒，被国际癌症研究机构（International Agency for Research on Cancer， IARC）归为I类致癌物质，在全世界人群中感染率超过90%。

论文摘要： EB病毒(Epstein-Barr Virus， EBV)属疱疹病毒科，1964年由Epstein和Barr在研究非洲儿童恶性淋巴瘤时发现的一种感染人类B淋巴细胞的疱疹病毒，被国际癌症研究机构（International Agency for Research on Cancer， IARC）归为I类致癌物质，在全世界人群中感染率超过90%。

Four adduct compounds are found for the former, and three are found for the latter. This indicates the DNA adduct formation capabilities both of 2-chloro benzamide and the photoproduct sample. Meanwhile the result of Ames experiments of them is positive. Thus we should pay more attention to important meaning of these results since the compound, which can produce adducts with DNA, may possibly be tumorigen or even carcinogen and mutagen.

结果表明，前者与DNA反应形成四个可辨认的加合物斑点，后者与DNA反应形成三个可辨认的加合物斑点，能与DNA加合的物质为潜在的&三致&物质，同时，二者的Ames试验结果显阳性这应当引起人们对灭幼脲环境安全性的重视。
