title: Influence of neonatal hypothyroidism on the development of ketone-body-metabolizing enzymes in rat brain.
abstract: Neonatal hypothyroidism markedly retarded the postnatal development of three ketone-body-metabolizing enzymes in rat brain during the first 4 weeks after birth. In contrast with normal animals, the brains of hypothyroid rats did not show decreases in the activities of these enzymes during the immediate postweaning period. The activities of ketone-body-oxidizing enzymes were markedly diminished in both non-synaptic and synaptic mitochondria isolated from 4-week-old hypothyroid rats compared with age-matched normal animals.
