To determine the role of thyrotropin-releasing hormone (TRH) in the regulation of thyroid-stimulating hormone (TSH) secretion in the perinatal period, a physiological approach of neutralizing circulating TRH in the fetal and early neonatal rat was employed. TRH-antiserum (TRH-AS) raised in rabbits and administered daily to low iodine-propylthiouracil (LID-PTU)-fed pregnant rats from days 12 to ...

The essential metal copper, zinc and iron content in starved virgin and pregnant rat tissue has been studied. The copper content of the whole rat, which was actually increased in pregnant rats, decreased in starved pregnant rats. The differences were significant in 19-day pregnant rats. The total copper content of the conceptus was not affected by starvation. Iron distribution and net tissue co...

The effect of aqueous extract of Cecropia glazioui Snethlage (Embauba) in the rat fetal development. This study was to complement previous assays on the physical and neurobehavioral development of rats resulted from oral administration of 1 g/kg/day Cecropia glazioui Snethlage (C. glazioui) aqueous extract (LD50 > 5 g·kg) in pregnant rats (periand post-natal studies). In the present study, the ...

BACKGROUND Iron deficiency anaemia during pregnancy is a global problem, with short and long term consequences for maternal and child health. Animal models have demonstrated that the developing fetus is vulnerable to maternal iron restriction, impacting on postnatal metabolic and blood pressure regulation. Whilst long-term outcomes are similar across different models, the commonality in mechani...
