Incorporation of 14C-1-palmitate into rabbit fetal lipids in vivo.

14C-1-palmitate was injected into rabbit fetuses in utero. Fetal liver, blood, carcass, and placenta collected after 15, 60, 180, and 360 minutes were analyzed for radioactivity in lipid classes. Incorporation differed with tissue and lipid. Highest total early specific activity was detected in plasma but later liver displayed the most extensive incorporation. Phospholipid incorporation was more rapid in all tissues than that of other glycerides. Plasma triglycerides did not display any radioactivity for 3 hours. Results point to multicentric origin of plasma lipids. Ready utilization of the palmitate indicates that maternal fatty acid transfer plays an important role in fetal lipid hemeostasis.

Correlation between morning urine estriol concentration and 24-hour estriol excretion.

In an attempt to circumvent the need for 24-hour urine collections for estriol analyses in assessment of fetal status, the possibility of using morning urine samples was investigated. Results indicate 1) good correlation between 24-hour estriol excretion and morning estriol concentration, and between corresponding E/C ratios, 2) similar morning and 24-hour estriol concentrations, 3) high dependence of estriol and creatinine excretion on 24-hour urine volume but not on morning volume, 4) larger variations in 24-hour than in morning urine volume, and 5) better consistency of values in morning than in 24-hour samples in pathologic pregnancy. The use of serial morning urine concentrations at least as an outpatient monitoring procedure is suggested.
