Effects of estrogenic chemicals on development.
The sum of the evidence supports the necessity to continue to investigate the developmental effects of estrogenic and antiestrogenic compounds when exposure occurs early in life. Additional studies will answer questions relevant to the molecular definition of the developmental or carcinogenic effects of estrogens such as hormone-induced gene alterations. These studies also support the need to u...
متن کاملEvaluation of 60 chemicals in a preliminary developmental toxicity test.
The number of chemicals in commerce which have not been evaluated for potential developmental toxicity is large. Because of the time and expense required by conventional developmental toxicity tests, an abbreviated assay is needed that will preliminarily evaluate otherwise untested chemicals to help prioritize them for conventional testing. A proposed short-term in vivo assay has been used in a...
متن کاملComparative toxicity of ten organic chemicals to four earthworm species.
Ten organic chemicals were tested for toxicity to four earthworm species: Allolobophora tuberculata, Eisenia fetida, Eudrilus eugeniae and Perionyx excavatus, using the European Economic Community's (EEC) earthworm artificial soil and contact testing procedure. The phenols were the most toxic chemicals tested, followed by the amine, substituted benzenes, halogenated aliphatic hydrocarbon, polyc...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
