Effects of Chronic Fetal Hyperglycemia
Abstra ct. Hyperglycemia has been shown to induce arterial hypoxemia in the chronically catheterized fetal sheep. To investigate the mechanism behind this glucose-induced hypoxemia, eight pregnant ewes and their fetuses were studied. Fetal glucose infusion (1 1.9±0.6 mg glucose/kg per min) was associated with a doubling of the fetal plasma glucose concentration with concomitant elevation of the...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Hemodynamic effects of bradycardia in the fetal lamb.
BRINKMAN, CHARLES R. III, GARY H. JOHNSON, AND N. S. ~SSALI. Hemodynamic effects of bradycardia in the fetal lamb. Am. J. Physiol. 223(6) : 1465-1469. 1972.-The hemodynamic impact of induced cardiac deceleration were studied in near-term fetal lamb. Vagal stimulation resulted in rhythmic or arrhythmic bradycardia, each type having somewhat different effects on arterial pressure, stroke volume, ...
متن کاملMyocardial function and hemoglobin oxygen affinity during hyperglycemia in the fetal lamb.
To determine the effects of maternal hyperglycemia on fetal hemodynamic and cardiac function, a study was carried out on nine chronically catheterized fetal sheep. In six fetuses, glucose was infused intravenously with an initial dose of 5 mg/kg per min. Data were compared with controls. This dose was gradually increased to 16 mg/kg per min by the fifth day. The initial blood glucose was 14.7 +...
متن کاملDifferential Effects of Chronic Pulsatile versus Chronic Constant Maternal Hyperglycemia on Fetal Pancreatic β-Cells
Constant maternal hyperglycemia limits, while pulsatile maternal hyperglycemia may enhance, fetal glucose-stimulated insulin secretion (GSIS) in sheep. However, the impact of such different patterns of hyperglycemia on the development of the fetal β-cell is unknown. We measured the impact of one week of chronic constant hyperglycemia (CHG, n = 6) versus pulsatile hyperglycemia (PHG, n = 5) vers...
