Diphenyl ditelluride effect on embryo/fetal development in mice: interspecies differences.

It is well established that diphenyl ditelluride, (PhTe)(2), is a potent teratogen in rats, however, little is known about its effects on embryo/fetal development in mice. The present study was undertaken to investigate whether any differences exist on embryo/fetal development of mice exposed to (PhTe)(2) during distinctive periods of gestation compared to rats. Dams were treated subcutaneously (s.

Sub-chronic exposure of adult male rats to diphenyl ditelluride did not affect the development of their progeny.

The present study was undertaken to evaluate the toxicity of diphenyl ditelluride [(PhTe)(2)] exposure on the progeny of Wistar male rats. Male rats were exposed to (PhTe)(2) subcutaneously for 4 weeks (wk) at the dose of 0.006 mg/kg and 8-wk at the dose of 0.

Adult male rats sub-chronically exposed to diphenyl diselenide: Effects on their progeny.

The present study was conducted to evaluate the toxicity of diphenyl diselenide [(PhSe)2] exposure on the progeny of Wistar male rats. Male rats were exposed to (PhSe)2 subcutaneously for 4 weeks at the dose of 5.0 mg/kg and 8 weeks at the dose of 2.

Assessment of reproductive toxicity in male rats following acute and sub-chronic exposures to diphenyl diselenide and diphenyl ditelluride.

The present study was conducted to evaluate the toxicity of the exposure to diphenyl diselenide [(PhSe)2] and diphenyl ditelluride [(PhTe)2] on reproductive system in Wistar rats. Adult male rats were exposed intraperitonealy (acute) or subcutaneously (sub-chronic, during 4 or 8 weeks) to (PhSe)2 or (PhTe)2 prior to mating. A number of biochemical parameters in rat testes were examined, such as delta-aminolevulinate dehydratase (delta-ALA-D) activity, lipid peroxidation, glycogen content and components of the antioxidant defenses (superoxide dismutase (SOD) activity and ascorbic acid concentration).
