title: [Effect of thyroxine on the activity of a series of mitochondrial enzymes during the process of development].
abstract: The activity of alpha-glycerophosphate dehydrogenase and succinate dehydrogenase suffers almost no changes during the chick embryogenesis, whereas the activity of cytochrome oxidase increases by 20--25%. The activity of these enzymes in the embryos exceeded that in the adult birds. The injection of thyroxine during embryogenesis did not affect the activity of the enzymes under study but in chickens stimulated the activity of mitochondrial enzymes. The increase of activity of alpha-glycerophosphate dehydrogenase, cytochrome oxidase and succinate dehydrogenase was also noted in young rats.
