用小鼠皮肤的实验研究表明,致癌作用包括两个阶段,即引发作用与促进作用。近年来人们证明致癌作用两阶段的过程不但适用于小鼠皮肤,而且也适用于其它器官,以致内脏,如肝、食管、胃、结肠、乳腺和肺。本文旨在进一步肯定抗氧化剂二丁基羟甲苯(BHT)对于小鼠肺癌的发生起着促进剂的作用,以及进一步研究氨基甲酸乙酯与 BHT 促使小鼠肺癌形成中的相互关系。 Experimental studies with mouse skin show that carcinogenic effects include two stages, namely, triggering and promoting effects. In recent years, it has been demonstrated that the two-stage process of carcinogenesis not only applies to the skin of mice, but also to other organs such that the internal organs such as the liver, esophagus, stomach, colon, breast and lungs. This article aims to further confirm the anti-oxidant dibutylhydroxytoluene (BHT) plays an accelerant role in the development of lung cancer in mice, and to further study the relationship between urethane and BHT to promote the formation of lung cancer in mice.
