                            <p>Böylece meydana gelen elektroîii metil katyonları biraz önce konu edilen nükleyik asit ve proteinde mevcut nükleofil bileşenlerle reaksiyona girerler (10).Nitrozo bileşikler için diğer bir mekanizma Argus (9) tarafından önerilmiştir. Bu öneri dioksamn tavşanların karaciğerinde kanserojen etki göstermesi sonucuna dayanır. Siklik bir eter olan dioksan yapı bakımından, N nitrozo piperidin, N - nitrozo morfolin ve N - nitrozo piperazinin yapısına benzemektedir. Son bileşikler, bu grubun en etkin kanserojen maddeleridir.</p></trans-abstract>

Another mechanism for nitroso compounds was proposed by Argus (9). This suggestion is based on the carcinogenic effect of dioxane on the liver of rabbits. Dioxane, a cyclic ether, is structurally similar to N-nitroso piperidine, N-nitroso morpholine and N-nitroso piperazine. The last compounds are the most potent carcinogens in this group.</p></abstract>
