PG - 660-4 LID - 10.3109/15376516.2013.834015 [doi] AB - Studies of our group has demonstrated that (PhSe)2 plays some pharmacologic activities. In addition, it is possible that this compound would be an alternative source of organic selenium in animal foods. However, previous works showed that diphenyl diselenide (PhSe)2 and diphenyl ditelluride (PhTe)2 are toxic for mammals, but their undesirable effects were never tested in avian models. Then, the present study was carried to examine the possible teratogenic effects of (PhSe)2 and (PhTe)2 on chicken embryo development. The eggs were injected with (PhSe)2 at 0, 1 and 10 nmol or with (PhTe)2 at 4 nmol. The control was injected with 10 microl of soya bean oil (vehicle). In order to determine the possible toxic effect of these chemicals, we measure the embryo dimensions, the encephalon, heart and liver weight, thiobarturic acid reactive species (TBARS) level and the delta-aminonevulinate dehydratase (ALA-D) activity. (PhSe)2 and (PhTe)2 did not affect the embryo dimensions. Treatment with (PhSe)2 at 10 nmol per egg caused a increase on TBARS level and on ALA-D activity of the liver tissue, whereas (PhTe)2 decreased encephalon weight, had a tendency to increase to increase TBARS level but did not affect ALA-D activity. Taken together, these results indicate that (PhSe)2 and (PhTe)2 are slightly toxic for chicken embryos. Furthermore, (PhTe)2 caused a decrease in encephalon, which indicates its neurotoxicity. Finally, these results indicate that (PhTe)2 seems not be promissory for therapeutic applications, whereas (PhSe)2 could be of clinical and/or nutritional concern, which will be target for further researches.
