Phenytoin and magnesium sulfate effects on fetal heart rate tracings assessed by computer analysis.

Objective: To compare the effects of maternally administered phenytoin and magnesium sulfate on the fetal heart rate (FHR) using computer analysis.

Methods: Thirty-six nonlaboring preeclamptic women between 27-41 weeks' gestation were treated with either phenytoin or magnesium sulfate in a nonrandomized fashion. All fetuses were deemed to be well by traditional electronic-biophysical criteria.

[Potter syndrome caused by bilateral renal agenesis and duodenal atresia].

A case of Potter syndrome secondary to renal agenesia and duodenal atresia with anular pancreas is presented. The karyotype was 47 XY-21. We discuss the antenatal diagnosis and the perinatal management.

[Nutritional changes caused by the germination of legumes commonly eaten in Chile].

The changes promoted by germination on phytates, oligosaccharides, crude protein, amino acids and riboflavin contents of black and white cultivars of beans, lentils, chicken-pea and peas, were studied. Seeds germination was carried out in darkness at 25 degrees C and 85% RH during 72 hours, previously soaked overnight in a solution of sodium hypochlorite at a concentration of 50 ppm. Germination capacity was assessed by determining hypocotyl and epicotyl lengths and percent of sprouted seed.

Uterine-umbilical artery Doppler velocimetry in pregnant women with systemic lupus erythematosus.

We evaluated continuous wave uterine-umbilical artery Doppler velocimetry for predicting pregnancy outcome in women with systemic lupus erythematosus (SLE). Lupus anticoagulant (LAC) and anticardiolipin (ACL) antibody status also were correlated with Doppler results and outcome. Three Doppler vascular patterns were identified in 27 pregnancies of 26 women with SLE.

Purification and partial characterization of transglutaminase from Physarum polycephalum.

An intracellular form of calcium ion-dependent transglutaminase (R-glutaminylpeptide:amine gamma-glutaminyltransferase, EC 2.3.2.

Intrauterine resuscitation in the severely distressed fetal dog.

Severe fetal distress was produced in 16 fetal dogs by successive and/or prolonged occlusion of the maternal abdominal aorta in an acute surgical preparation, and was characterized in fetal arterial blood of 7.06 for pH, 10 mm Hg for O2, 127 mm Hg for CO2, and fetal heart rate decelerations. Five fetuses recovered spontaneously in utero and delivered normally; 3 needed maternal oxygenation before delivery; 3 suddenly died in utero; 5 fetuses were delivered while still alive in utero when the tpH reached 6.

Nutritional quality of lupine (Lupinus albus cv. Multolupa) as affected by lactic acid fermentation.

The effects of selected NRRL strains of Lactobacillus acidophilus, L. buchneri, L. cellobiosus and L.

A calcium-binding protein that may be required for the initiation of chromosome replication in Escherichia coli.

Starvation for isoleucine but not for other amino acids in an ilv- strain or the addition of valine in an ilv+ strain inhibits initiation of chromosome and minichromosome replication in stringent (Rel+) Escherichia coli, but it does not inhibit replication in relaxed (relA) mutants (Guzman et al, 1988). From these results, we concluded that, (1) oriC initiation of replication is inhibited by ppGpp, and (2) isoleucine is not needed for the protein synthesis required at initiation. These results led us to find an isoleucine-free protein whose de novo synthesis is the sole protein synthesis requirement for oriC initiation.

Umbilical artery Doppler velocimetry in pregnancies of less than 21 weeks' duration.

Most Doppler ultrasound investigations of the umbilical artery circulation have been confined to beyond 16 weeks' gestation. The purpose of this study is to explore the evolution of this circulation in human pregnancies of less than 21 weeks' gestation. We studied 169 low-risk pregnant women (125 longitudinally and 44 cross-sectionally) with a pulsed Doppler system on 357 separate occasions between 9 and 20 weeks of gestation.

Value of a screening fetal heart rate tracing in the latent phase of labor.

We studied the value of a screening fetal heart rate (FHR) tracing obtained on 405 women in the latent phase of labor on presentation to the labor-and-delivery suite. All pregnancies were at term and had a cephalic presentation. Thirty-two women in the sample studied underwent a cesarean section for fetal distress.

Heavy metals, chlorine and antibiotic resistance in Escherichia coli isolates from ambulatory patients.

The susceptibility of Escherichia coli strains isolated from ambulatory patients to heavy metals, chlorine and antibiotics was evaluated. It seemed that heavy metal resistance was associated with antibiotic resistance. On the other hand, chlorine resistant strains seemed to be more sensitive to antibiotics.

Early prenatal diagnosis of gastroschisis with transvaginal ultrasonography.

A case is reported in which gastroschisis was definitively diagnosed at 12 3/7 weeks' gestation by transvaginal ultrasonography. This is the earliest diagnosis reported in the literature and would seem to support the theory that gastroschisis and omphalocele are embryologically distinct entities.

A quantitative analysis of placental vasculature in the third-trimester fetus with autosomal trisomy.

Growth disturbance in the trisomic fetus is believed to be primarily fetal in origin. There has been only sparse description of placental pathology in the third trimester in these fetuses, and therefore the placental role in their growth and development remains unexplored. We performed quantitative morphometric analysis on the placentas of 18 fetuses with trisomy and ten normal control fetuses.

[Sweet lupine (Lupinus luteus, var. Aurea/Weico and Lupinus albus, var. Multolupa) proteins. II. Separation by electrophoresis].

The albumins and globulins extracted from Lupinus luteus var. Aurea/Weico and Lupinus albus var. Multolupa defatted flour samples were analyzed by polyacrilamide gel electrophoresis.

[Sweet lupine (Lupinus luteus, var. Aurea/Weico and Lupinus albus, var. Multolupa) proteins. I. Extraction and filtration by Sephadex].

Samples of Lupinus luteus, var. Aurea/Weico and Lupinus albus var. Multolupa flours were analyzed.

Pregnancy surveillance with Doppler velocimetry of uterine and umbilical arteries.

Previous studies with Doppler velocimetry have demonstrated a strong correlation between abnormal waveforms and fetal-maternal disease. This study was designed to evaluate the potential role of Doppler velocimetry as a screening test in routine prenatal care. Two hundred fifty-five pregnant women had routine monthly Doppler (systolic/end-diastolic ratio) studies on the uterine and umbilical arteries starting in the twentieth week of gestation.

[Prediction of fetal sex by ultrasonography].

Five hundred thirteen echographic reports are analyzed in order to predict fetal sex between 17 and 39 weeks of pregnancy. The diagnostic certainty was of 98.06%.

[Use of vaginal transducer in gyneco-obstetrical patients: preliminary experience].

Two hundred thirty five Transvaginal exams were done to 160 gynecology patients. The tolerance rate obtained in those patients with previous consent, was 87%. The exam was useful in particular follow-up ectopic pregnancy, vitality an location of early pregnancy.
