title: Pentobarbital sodium and chromosome abnormalities in rabbit blastocysts.
abstract: Female rabbits were injected with pentobarbital sodium at 1/4 h or 6 h post coitum. A slight delay in oocyte maturation was evident in animals killed at 17 h pc, however, zygote development appeared normal by 24 h pc. At 6 days pc, a greater frequency of chromosomally abnormal blastocysts was found in animals injected with pentobarbital than in control rabbits.
