1. Anatomopathological study in BALB/c mice brains experimentally infected with Toxoplasma gondii
Toxoplasmosis is one of the most important diseases of the nervous central system, leading to severe symptoms and, many times, irreversible sequelae. This work demonstrated the main anatomopathological lesions caused by Toxoplasma gondii in brains from experimentally infected BALB/c mice. We analyzed 51 cases of mice that developed toxoplasmosis after experi

2. Variação do volume de liquido aminiotico de gestantes com atividade fisica moderada em imersão em agua
Objective - To evaluate possible changes in the amniotic fluid index (AFI) among pregnant women practicing moderate physical activity in water immersion. Method: a prospective study was performed, comparing the AFI pre and post immersion in water for physical activity. Pregnant women from the Pre Natal Outpatient Clinic in the hospital of the University of C

3. Concentrations of vitamins A and E in amniotic fluid, extraembryonic coelomic fluid, and maternal serum in the first trimester of pregnancy.
Paired samples of amniotic fluid and coelomic fluid were obtained by transvaginal ultrasound guided amniocentesis from 15 women with an ultrasonographically normal pregnancy between 8 and 12 weeks' gestation. Vitamins A and E were measured in the two pregnancy fluids and in maternal serum by high performance liquid chromatography with detection by ultraviole

4. Maternal-Fetal Transfer and Amniotic Fluid Accumulation of Nucleoside Analogue Reverse Transcriptase Inhibitors in Human Immunodeficiency Virus-Infected Pregnant Women
This study was performed to investigate placental transfer of nucleoside analogue reverse transcriptase inhibitors (NRTIs) and their concentrations in amniotic fluid when given to human immunodeficiency virus (HIV)-infected pregnant women. A total of 100 HIV type 1-infected mothers receiving antiretroviral therapy, including one or more NRTIs, for clinical i

5. Arginine vasotocin in ovine fetal blood, urine, and amniotic fluid.
Arginine vasotocin ([8-arginine]-oxytocin) (AVT), the primary antidiuretic principle in submammalian vertebrates, has been reported to be present in mammalian pituitary and pineal glands. Although the most phyletically ubiquitous of the known neurohypophysial peptides, AVT is still not recognized as a mammalian hormone. We examined plasma, urine, and amnioti

6. 'De-watering' capabilities of surfactants in human amniotic fluid.
The phospholipid extracts from each of eleven samples of human amniotic fluid obtained from eleven full-term births were deposited as orientated monolayers adsorbed to glass. The surfaces were found to be rendered hydrophobic with maximum contact angles averaging 54.5 degrees while, upon withdrawing fluid, the edge of the saline pool receded to expose dry su

7. Placental transfer and tissue distribution of 14C-styrene: an autoradiographic study in mice.
The distribution of 14C-styrene was studied in the pregnant mouse using a whole body low temperature autoradiographic technique. In unsectioned tissues studied by liquid scintillation the concentrations of styrene and its metabolites in maternal and fetal blood and organs and in the placenta and amniotic fluid were determined. The organs which had higher con

8. Pharmacokinetics of Intravenous Acyclovir, Zidovudine, and Acyclovir-Zidovudine in Pregnant Rats
The pharmacokinetics and placental transfer of acyclovir and zidovudine monotherapies and acyclovir-zidovudine combination therapy were compared in the pregnant rat. Timed-pregnancy Sprague-Dawley rats were used for the study. Doses of 60 mg of each drug/kg of body weight in monotherapy and in combination therapy were given by intravenous bolus, and samples

9. The effects of continuous drainage of fetal fluids on salt and water balance in fetal sheep.
1. In nine chronically catheterized fetuses in which all lung liquid was drained continuously from the time of surgery, the effects of continuous drainage of fetal urine for 1 week on fetal renal function, lung liquid production and salt and water balance were studied. Fetal wellbeing, as judged by fetal growth, urinary osmolality, blood gas status, arterial

10. Mechanisms by which the pregnant ewe can sustain increased salt and water supply to the fetus.
1. Nine chronically catheterized pregnant ewes were monitored before, during and after 1 week in which fetal urine was drained continuously, to determine whether they could compensate for the resulting loss of salt and water and increase net supply across the placenta to the fetus. 2. Fetal growth and urine and lung liquid production were not affected by los

11. Transplacental transfer of cefuroxime in uncomplicated pregnancies and those complicated by hydrops or changes in amniotic fluid volume.
The transplacental transfer of cefuroxime was determined at antenatal fetal blood sampling in a cross sectional study of 78 patients between 15-35 weeks' gestation, 8-138 minutes after a maternal intravenous dose of 750 mg. Mean serum cefuroxime concentration, measured by high performance liquid chromatography, was 7.4 (95% confidence interval (CI) 6.8 to 8.

12. In vivo maternal-fetal pharmacokinetics of stavudine (2',3'-didehydro-3'-deoxythymidine) in pigtailed macaques (Macaca nemestrina).
To determine whether stavudine (2',3'-didehydro-3'-deoxythymidine) is actively transported in vivo across the placenta and to determine the extent of its transfer, stavudine was administered as an intravenous bolus to four near-term macaques (Macaca nemestrina) (5 mg/kg of body weight via the femoral vein) or to their fetuses (10 mg/kg via the carorid artery
