Protein synthesis is significantly decreased in the near-term ovine fetus in response to induced hypoxemia of several hours' duration. We therefore sought to determine the extent to which DNA synthesis rates as an index of tissue mitotic activity are

To examine the effect of sustained hypoxia on the expression of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) type 1 and 2 genes in preterm fetal sheep.Fetal liver and kidney as well as placental tissues were collected at days 111-113 of gestati

The fetal environment is well suited for normal brain growth and development with oxygen availability well in excess of oxidative needs. With impairments in blood gas exchange, cerebral oxidative metabolism is initially maintained by an increase in c

Cerebral oxidative metabolism and associated circulatory responses were determined in 14 unanesthetized fetal sheep near term, during a normoxic control period and subsequently, during four days of prolonged and graded hypoxemia induced by progressiv

As in postnatal life, behavioral states when evident in utero are also seen to influence the metabolic activity and/or circulation of several organ systems if not the global metabolic and circulatory activity of the fetus. In some instances this effe

Experiments were conducted in 12 chronically-catheterized pregnant sheep to examine the effect of prolonged hypoxaemia secondary to the restriction of uterine blood flow on fetal oxygen consumption. Surgery was performed at 115 days gestation to plac

Alterations in oxygenation are known to influence directly prostaglandin (PG) production by tissues such as fetal and neonatal lung cells, and by the fetal brain. However, at the present time there is no systematic study of the effects of altered oxy

Methods have been developed for the placement of cannulas in the lateral cerebral ventricle and cisternum magnum of the fetal lamb. Three to seven days after surgery, perfusion of the cerebral ventricular system was carried out in unanesthetized lamb
