Embryotoxicity and teratogenicity of styrene and styrene oxide on chick embryos enhanced by trichloropropylene oxide. 1979

J T Kankaanpää, and K Hemminki, and H Vainio

The effects of TCPO (trichloropropylene oxide) on the embryotoxicity and teratogenicity of styrene and styrene oxide and chick embryos were investigated. The compounds were injected into the air space of the eggs in a total volume of 25 microliter on the third day of embryogenesis. TCPO increased embryotoxicity and teratogenicity of styrene and styrene oxide. Our results present evidence that the epoxides possess embryotoxic and teratogenic properties in chick embryos.

UI	MeSH Term	Description	Entries
D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
