Abstract: | This study was designed to quantitate the effects of 5-(3,3-dimethyl-1-triazeno)-imidazole-4-carboxamide (DIC) and 5-(3,3-bis(2-chlorethyl)-1-triazeno)-imidazole-4-carboxamide (BIC) on growth and selected components of rat fetal organs. Twelve-day pregnant rats were given single intraperitoneal injections of 600 mg/kg of DIC and 900 mg/kg of BIC and autopsied on day 21 of gestation. Fetal liver, brain, kidney, and placenta were removed, weighed, and assayed for total DNA, RNA, and protein. DIC significantly reduced weight, total DNA, RNA, and protein of all four fetal organs as compared to age-matched controls. The brain was most severely affected by this compound. BIC also significantly reduced weight, DNA, RNA, and protein of fetal brain, kidney, and placenta, but in fetal liver only weight and total protein were significantly depressed, while DNA and RNA remained essentially unchanged. The effect of BIC was maximal on the placenta. |
