...T. Wobbes; H.J. Huisjes Employing several methods, we investigated the identity of a substance in human amniotic fluid which gives a positive agglutination reaction with latex-albumin. It was shown that the substance was particulate and originated from the vernix caseosa. Latex agglutination...

...H.J. Huisjes; T. Wobbes Previous studies have suggested the possibility of diagnosing post-maturity by the demonstration of C-reactive protein (CRP) in amniotic fluid by latex agglutination tests. In our study we found that 72 of 75 samples of amniotic fluid obtained from mothers at varying times...

...U. Goebelsmann; B.A. Work, Jr. The concentration of unconjugated (‘free’) estriol (E 3 ), estriol-3-sulfate, estriol-16-glucosiduronate (E 3 16Gl) and estriol-3-sulfate-16-glucosiduronate (E 3 -SGl) in amniotic fluid was measured by fluorimetry using tritiated ‘free’ and conjugated E 3 as internal...

...B. Wiegershausen; B. Klausch; G. Hennighausen; I. Paegelow; R. Raspe Amniotic fluid from the different periods of pregnancy was investigated on its content of kininogen, kinins and the activity of the kininolytic enzymes. In contrast to plasma, the kininogen content in the amniotic fluid is very...

...J.W. Dudenhausen; G. Kynast; A.-M. Lange-Lindberg; E. Saling The lecithin content of 157 amniotic fluid samples taken from 60 patients who had been treated with Fenoterol over a long period of time (longer than 30 mg/daily per os for 14 days; intravenous infusion for longer than 7 days...

...M. Potier; L. Dallaire; S.B. Melançon Α-Galactosidase activity has been assayed using 4-methylumbelliferyl-Α-galactoside as substrate in 66 amniotic fluid samples obtained between the 10th and 41st week of gestation. The mean activity decreases slightly between the 10th and 29th week from 2 to 1.4...

...Harlan R. Giles; Charles D. Lox; Wayne Heine; C.D. Christian Amniotic fluid testosterone levels were measured by a sensitive and specific radioimmunoassay technique from 75 term pregnancies and from 57 pregnancies prior to 20 weeks gestation. Statististically significant differences (p < 0.05...

...O.R. Kling; W.M. Crosby; J.A. Merrill The determination of amniotic fluid total lecithin/sphingomyelin ratio, creatinine concentration, fetal fat cells and presence of bilirubin (Δ OD 450 ) was used to study 201 amniotic fluids from 144 pregnancies. The total L/S ratio and creatinine concentration...

...R.W. Armstrong; S.B. Effer; E.V. YoungLai Human amniotic fluid obtained near term was examined for total progesterone, progesterone binding and total protein. Samples from patients bearing male (M) fetuses had 25.5 ± 2.0 ng/ml (n = 45) and female (F) fetuses 23.8 ± 2.7 ng/ml (n = 32). Bound...

...George H. Nelson; Katsuto Eguchi; James C. McPherson There is a significant increase in acetone-precipitable lecithin (APL) concentration with advancing gestation in fetal lung tissue and amniotic fluid in rats. Measurement of the APL concentration in fetal lung tissue and/or amniotic fluid...

...H.W.H. Feijen; G.C. di Renzo; J. de Haan; P.C.W. Houx; J. Nederstigt The amylase concentration in the amniotic fluid (ACAF) was studied in 138 subjects in relation to duration of pregnancy, fetal weight, L/S ratios and neonatal occurrence of respiratory distress syndrome (RDS). ACAF was found...

... or Streptococcus intermedius for 2–4 days. 6 other animals in mid pregnancy were exposed to one of the bacteria mentioned for 30 days. Before inoculation, aerobic and anaerobic culture specimens from cervix and amniotic fluid were obtained. At delivery by caesarean section, in addition to culture specimens...

...J. Puolakka; A. Kauppila; J. Vuori The concentrations of norepinephrine in amniotic fluid and maternal plasma were measured in 71 third trimester pregnancies, 31 of which were uncomplicated and 40 complicated. The amniotic fluid norepinephrine concentration (mean ± SD) in cases of hypertension...

...Menachem Granat; Mordechai Sharf; Ben Avi. Weissman The presence of an enkephalin-like substance (‘humoral endorphin’) in human maternal and cord blood, as well as in amniotic fluid, has been demonstrated in this study. Utilizing antibodies to leucine-enkephalin, it was found that the level...

...P. de Grandi; M. Ramzin; A. Lüthi; M. Hinselmann Amylase concentration, L/S ratio and lecithin concentration were measured in 110 samples of amniotic fluid in 106 uneventful pregnancies. Amylase concentrations lower than 200 U/l corresponded significantly (p < 0.001) to a gestational age less...

...H.W.H. Feijen; J. de Haan; C.B. Martin, Jr.; J. Nederstigt; P.C.W. Houx The amniotic fluid lecithin/sphingomyelin ratio (L/S ratio) of stumptail macaque monkeys ( Macaca arctoides ) was investigated by means of serial amniocenteses during the second half of pregnancy. Ten dated pregnancies were...

... progressed with time, and delivery was achieved within 21 h. Significant elevation of prostaglandin E (PGE) and F (PGF) levels in amniotic fluid was noted with the progress of cervical dilatation. It appears that the release of PGE and PGF is dependent on uterine stretching and/or the subsequently induced...
