there are many reports that show the teratogenic effects of phenobarbital can be decreased by stimulation of maternal immune system. therefore, in this study, the prophylactic effects of levamisole and vitamin e on teratogenic effects of phenobarbital were compared. this study was performed on 20 pregnant rats that were divided into four groups. control group received normal saline and test gro...

BACKGROUND To establish zebrafish as a developmental toxicity model, we used 7 well-characterized compounds to examine several parameters of neurotoxicity during development. METHODS Embryos were exposed by semistatic immersion from 6 hrs postfertilization (hpf). Teratogenicity was assessed using a modified method previously developed by Phylonix. Dying cells in the brain were assessed by acr...

The management of pregnant women with mechanical heart valves is challenging. Recently, based on small numbers of patients and poor-quality data, correspondence from Aventis Pharmaceuticals Inc has described treatment "failures" and concerns about teratogenicity with the use of the low-molecular-weight heparin (LMWH) enoxaparin. The company issued a "Warning" that enoxaparin should not be used ...

This study investigated the teratogenicity of ethanol in several different strains of chickens. The chick embryo provides a useful model for studying the fetal alcohol syndrome. Two broad classifications of chicks, each containing many strains, are commercially available for use: broilers and layers. Teratogenicity of ethanol in broilers and layers was studied by examining three different param...

Endocrine-disrupting chemicals (“EDCs”, hereafter) have attracted special attention due to its reported toxic effects on children, pregnant woman and elderly. Current EDC-based prioritization approaches do not explicitly include human health risks. This study proposed a theoretical perspective on development of a human health risk-based prioritization framework for monitoring endocrine-disrupti...
