Abstract
Pulse-doses of 7,12-dimethylbenz[a]anthracene and 7,8,12-trimethylbenz[a]anthracene share a remarkable ability to damage selectively endocrine glands and targets of hormones in female rodents. Both compounds depress synthesis of DNA in ileum and spleen.
In CF-1 mice, 7,12-dimethylbenz[a]anthracene and 7,8,12-trimethylbenz[a]anthracene severely injured the ovary and elicited ovarian tumors and leukemia, whereas the adrenal was uninjured by these compounds. 3-Methylcholanthrene and benzo[a]pyrene induced leukemia, but ovarian tumors did not develop.
In adult rats, a pulse-dose of 7,8,12-trimethylbenz[a]anthracene caused adrenal apoplexy but did not evoke ovarian tumors.
