...D. Gripois; M. Valens The postnatal evolution of adrenal phenylethanolamine-N-methyltransferase (PNMT) activity is slightly accelerated by hypothyroidism and slowed by hyperthyroidism. In 14-day-old rats a single stimulation of the adrenals by insulin-induced hypoglycemia does not lead to any...

...Morton E. Weichsel, jr.; Brian R. Clark; Russell E. Poland Experimental hypothyroidism in the neonatal rat is known to retard cerebellar DNA biosynthesis with a return to normal of the ultimate cell number. Because of the known shift to a later age in the developmental curve for cerebellar...

...B.R. Clark; M.E. Weichsel jr.; R.E. Poland Experimental hypothyroidism in the neonatal rat is known to result in a delay in cerebellar DNA biosynthesis. Because of the known high correlation between rate of DNA biosynthesis and thymidylate synthetase (TS) activity in neonatal hyperthyroidism...

...Susan Carney Crane; Brian L.G. Morgan The in vitro and in vivo utilization of 14 C-β-hydroxybutyrate (BOHB) by the brain in neonatal hypothyroidism was studied in rat pups made hypothyroid by feeding dams a diet containing 0.02% propylthiouracil during pregnancy and lactation. In the in vitro...

...D. Gripois; M. Valens The influence of neonatal hyper- and hypothyroidism on plasma dopamine-beta-hydroxylase (DBH) activity was studied in young rats from 5 to 30 days of extrauterine life. In the newborn rat, plasma DBH activity was four times higher than in the adult. In the control animals...

...Charles Oliver; Pierre Giraud; Pierre Gillioz; Bernard Conte-Devolx; Ricardo Usategui The effect of neonatal hypothyroidism and neonatal caloric deprivation on brain TRH levels and serum and pituitary TSH levels has been determined in rats on the following postnatal days: 1, 5, 10, 15, 25, 40...

...D. Gripois; C. Klein; M. Valens We studied the noradrenaline content, and monoamine oxidase (MAO) and catechol-O-methyltransferase (COMT) activities in brown adipose tissue (BAT) of normal, hypothyroid, and hyperthyroid developing rat. In the newborn, thyroid hormones are necessary for the increase...

...D. Gripois; M. Valens Norepinephrine uptake and turnover rate were measured in the interscapular brown adipose tissue of normal and hypothyroid young rats. At the age of 15 days, hypothyroidism lowers the uptake of norepinephrine. This fact could partially explain why the norepinephrine content...

.... Thus, it is possible that increased fetal TH activity after prenatal GC plays a role in accelerating fetal lung maturation. However, this hypothesis has remained untested due to the lack of a suitable animal model. In the hyt/hyt mouse primary hypothyroidism occurs due to a point mutation in the beta...
