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。

As to the curing reaction of the modified phenolic epoxy resins, there is the etherification reaction between phenolic hydroxyl groups and epoxy groups. When the secondly modified epoxy resins are cured at higher temperatures respectively, the absorbance increasing at 1670Cm〓 and 1640Cm〓 are indicative of aminolysis reaction.

对于改性酚醛环氧树脂的固化反应，有酚羟基和环氧基间的醚化反应，二次改性环氧树脂在较高的温度固化时，1670Cm〓和1640Cm〓吸收峰的增加说明有氨解反应。
