An inhalation teratology study was conducted in rats at 10, 50 and 250 ppm ethylene glycol monoethyl ether (EGEE) and in rabbits at 10, 50 and 175 ppm EGEE. This study was designed to supplement a study conducted for NIOSH which showed teratogenic effects in rats at 200 ppm EGEE and in rabbits at about 160 ppm EE. In this study, EGEE was found not to cause teratogenic effects at concentrations ...

The embryonic/fetotoxic effects of DEHP on pregnant mice (ddY-Slc female x CBA male) were studied. DEHP was administered orally in dosages of 0.05 ml/kg to 30.0 mg/kg on day 6, 7, 8, 9 or 10 of gestation. A single administration of DEHP over 0.1 ml/kg (1/300 of LD50) on day 7 of gestation decreased the numbers and the body weight of living fetuses, whereas no significant changes in the numbers ...

The unmet medical need of providing evidence-based pharmacotherapy for pregnant women is recognized by the regulatory bodies. Physiologically based pharmacokinetic (PBPK) modeling offers an attractive platform to quantify anticipated changes in the pharmacokinetics (PKs) of drugs during pregnancy. Recent publications applying a pregnancy PBPK module to the prediction of maternal and fetal expos...

Timed-pregnant Fischer 344 rats and New Zealand White rabbits were exposed to ethylene glycol monobutyl ether vapors by inhalation on gestational days 6 through 15 (rats) or 6 through 18 (rabbits) at concentrations of 0, 25, 50, 100 or 200 ppm. The animals were sacrificed on gestational day 21 (rats) or 29 (rabbits). In rats, exposure to 200 or 100 ppm resulted in maternal toxicity (clinical si...

Synthetic pyrethroid insecticides have been widely used for years to prevent harmful effects of insects and control disease vectors. In this study, the resveratrol against potential toxicity permethrin, an effective derivative, on fetus were investigated. Accordingly, Wistar female rats divided into four groups as Control, Sham, Permethrin, Permethrin + Resveratrol. Lung, liver, kidney small in...
