Abstract
The effects of dieldrin and mirex on Ehrlich ascites tumor cells were assessed, using certainin vivo (in mice) andin vitro measurements. Mirex retarded the development of Ehrlich ascites tumorin vivo, but dieldrin did not. Effects of dieldrin onde novo RNA purine synthesis from formatein vivo were slight, while mirex inhibited the synthesis of both RNA purines. Dieldrin inhibited thein vitro incorporation of thymidine, uridine, and L-leucine into DNA, RNA, and protein, respectively, but mirex was virtually without effect.
