环境中有许多种类的致突变物质,其中大部分与癌肿发生有关,因此研究环境中抑制致突变作用的因素对于人类的健康是非常重要的。这些因素可分为两类,一类称为致突变剂破坏物质(desmutagen)。另一类称为生物性抗致突变剂(bio-antimutagen)。前者主要是在细胞外直接或间接使致突变剂失活或破坏。而后者则是在细胞内抑制突变作用的自身过程。
There are many kinds of mutagenic substances in the environment, most of which are related to the occurrence of cancer. Therefore, it is very important for human health to study the factors that inhibit the mutagenicity in the environment. These factors can be divided into two categories, one called desmutagen. The other is called bio-antimutagen. The former mainly inactivates or destroys the mutagenic agent directly or indirectly outside the cell. The latter is its own process of inhibiting mutations in cells.
