To further investigate the maturation of the cardiopulmonary baroreflex, we measured the effects of a 45-min blood volume expansion to an increase in right atrial pressure of approximately 4 mmHg in chronically instrumented newborn (n = 17) and older

The renin-angiotensin system is a major determinant of arterial pressure and volume homeostasis in mammals through the actions of angiotensin II, the proteolytic digestion product of angiotensinogen. Molecular genetic studies in several human populat

In addition to regulating developmental changes in body fluid content, the newborn kidney must maintain a positive sodium balance to ensure adequate body growth. Mechanisms by which the developing organism perceives changes in volume and the manner i

The transition from fetal to newborn life is associated with significant endocrine changes. Some of these changes may be triggered by the effects of spontaneous respiration, increased oxygenation and removal of the placental circulation at birth. We,

Intrarenal arterial infusion of alpha 1-adrenergic agonists decreases renal blood flow, glomerular filtration rate, and water and sodium excretion to a greater extent in fetus and newborn than in adult sheep. In vitro renal vascular effects of alpha

The renal hemodynamic response to direct electrical stimulation of renal nerves was studied in conscious and chronically instrumented fetal (130-142 days gestation; term 145 days), newborn (7-12 days postnatal), and adult nonpregnant sheep. Renal ner

This review summarizes current understanding of the role of atrial natriuretic factor (ANF) during fetal and postnatal life. The cardiac localization of ANF synthesis changes during development from ventricular to predominantly atrial cardiocytes. AN

Studies were carried out during fetal life in sheep to determine the relationship of 2,3-diphosphoglycerate (DPG), the intracellular red cell and extracellular pH, and the switchover to adult hemoglobin synthesis in regulating the position of the fet

The renal hemodynamic and functional responses to sequential reductions of fetoplacental blood volume were studied in two groups of chronically catheterized fetal lambs: less than 120 d gestation, n = 9 and greater than 130 d gestation, n = 7. Signif
