OGAWA, Y. Fetal Pulmonary Surfactant in Amniotic Fluid of Ewes. Tohoku J. exp. Med., 1972, 108 (4), 307-315-The phospholipids in the amniotic fluid from healthy pregnant ewes at various stages of gestation were analyzed in relation to the fetal pulmonary surfactant. The most abundant phospholipid was phosphatidylcholine which increased as the term approached. Analysis on the positional specific...

The placental hormone leptin has important functions in fetal and neonatal growth, and prevents depressed respiration in leptin-deficient mice. The effect of leptin on respiratory distress suffered by low birth weight and premature infants has been studied. However, it is unclear how leptin enhances lung maturity in the fetus and ameliorates neonatal respiratory distress. In the present study, ...

Recently, multiple time scale characteristics of heart dynamics have received much attention for distinguishing healthy and pathologic cardiac systems. Despite structural peculiarities of the fetal cardiovascular system, the fetal heart rate(FHR) displays multiple time scale characteristics similar to the adult heart rate due to the autorhythmicity of its different oscillatory tissues and its i...

An attempt has been made to monitor by continuous fetal heart rate according all women admitted in labour. Altogether 85% of the 1070 patients delivered at one hospital were monitored in 1973 and 92% in 1974. Perinatal mortality fell significantly from levels in preceding years to 15-8 and 11-7 per 1000 births, respectively, in 1973 and 1974. The fall was primarily due to the elimination of int...

The chief obstetrical problems encountered today in the prenatal evaluation of the high-risk fetus are presented. Advantages and pitfalls or recent techniques utilized in the management of the high-risk pregnancy are discussed. They include: a prenatal scoring system for identifying the high-risk population; examination of the karyotype of cells in amniotic fluid, and quantitation of alpha-feto...

Caesarean section rates are inexorably rising which has led to the possibility of negative impact on maternal and neonatal health. Present study was aimed to compare the factors associated with caesarean and vaginal births among pregnant women. A retrospective study was conducted in Obstetrics and Gynaecology Department, Punjab Institute of Medical Sciences, Jalandhar (Punjab, India) during the...

Dystocia in buffalo due to fetal causes is not common. However there are reports suggesting dystocia due to dropsical condition of fetus. Present case reports one of the fetal dropsical conditions in buffalo. In this case we report a successful management of dystocia due to fetal ascites in Murrah buffalo by incising the fetal abdomen to take out the fluid from peritoneum. Keywords— Fetal Ascit...

There are more than twenty years ago, caesarean sections for fetal distress were not performed if the fetal weight was less than 1000g or gestational age less than 28 weeks of amenorrhea (WA) [1]. Today, with advances in neonatology, survival to birth weight around 500 grams or gestational ages from 22 weeks of amenorrhea have been reported. This leads practitioners to perform caesarean section...

conclusions in the absence of associated anomalies, the risk of incidence of adverse events does not appear to be increased significantly with isolated sua. therefore, supplementary assessment and invasive tests are not recommended in fetuses with isolated sua, unless fetal abnormalities are detected in routine evaluations. background the umbilical cord normally consists of two arteries and one...

Widespread use of fetal heart rate monitoring for intrapartum fetal surveillance preceded our detailed understanding of the behaviour and regulation of the fetal cardiovascular system during labour. The fetal heart rate is sensitive to fetal hypoxaemia and hypoxia, but lacks specificity for fetal acidosis, the end point of unmitigated hypoxaemia and hypoxia. Original interpretations of fetal he...
