 | | In this context it should be remembered that as well as the protective immunological effects postulated for conditions such as leukemia, deleterious effects--involving the transmission of agents such as HBV, human immunodeficiency virus, and fat-soluble chemicals--are also possible. |
 | | Although there is some evidence that preconceptional carcinogenesis involves conventional gene mutations showing Mendelian inheritance (131,132,137,139), in many contexts the high frequency of the effects and odd inheritance patterns suggest that other novel mechanisms are involved (148). |
 | | For some of the factors, this could easily be done by the use of several carcinogenic agents and species and with carefully planned investigations. |
