1. INFLUÊNCIA DO HIPOTIREOIDISMO GESTACIONAL EXPERIMENTAL SOBRE A FUNÇÃO CARDIOVASCULAR DA PROLE DE RATAS. / INFLUENCE OF EXPERIMENTAL GESTATIONAL HYPOTHYROIDISM ON CARDIOVASCULAR FUNCTION ALONG THE LIFE OF OFFSPRING IN RATS.
Gestational hypothyroidism is a prevalent disorder in pregnant women. We aimed to investigate the impact of experimental gestational hypothyroidism (EGH) on cardiovascular and autonomic nervous systems (ANS) in the offspring of rats. EGH was induced with methimazole (MMI) 0.02% in drinking water from day 9 of gestation until birth. Sixty days old offspring f

3. Efeitos agudos do fumo sobre a hemodinâmica da circulação feto-materno-placentária / Acute effects of maternal smoking on fetal-placental- maternal system hemodynamics
Objective - To study acute hemodynamic alterations in the fetal-placental maternal system immediately after maternal exposure to nicotine. Methods - This is a noncontrolled experimental study involving 21 pregnant smoking women, randomly selected, with uncomplicated pregnancies and without risk factors for fetal heart disease. Patients underwent ultrasound a

4. Comportamento do fluxo venoso pulmonar durante o ciclo respiratório fetal
Introdução- Os movimentos respiratórios têm influência na circulação fetal. Sua presença indica um sistema nervoso intacto, não deprimido, refletindo o bem-estar do concepto. Acredita-se que, em apnéia, a pressão exercida pelos órgãos intratorácicos no coração fetal, em particular os pulmões não expandidos, limita a distensibilidade ventric

5. Alternative parameters for echocardiographic assessment of fetal diastolic function
Alternative methods to assess ventricular diastolic function in the fetus are proposed. Fetal myocardial hypertrophy in maternal diabetes was used as a model of decreased left ventricular compliance (LVC), and fetal respiratory movements as a model of increased LVC. Comparison of three groups of fetuses showed that, in 10 fetuses of diabetic mothers (FDM) wi

6. Acute Effects of Maternal Smoking on Fetal-Placental-Maternal System Hemodynamics
OBJECTIVE: To study acute hemodynamic alterations in the fetal-placental maternal system immediately after maternal exposure to nicotine. METHODS: This is a noncontrolled experimental study involving 21 pregnant smoking women, randomly selected, with uncomplicated pregnancies and without risk factors for fetal heart disease. Patients underwent ultrasound and

7. The effects of frusemide, saralasin and hypotension on fetal plasma renin activity and on fetal renal function.
1. In eleven chronically catheterized fetal sheep aged 124-142 days, hypotension caused by infusion of sodium nitroprusside (1.6-3.3 mg/h) and competitive antagonism of angiotensin II by saralasin (3.3 mg/h) both caused a fall in fetal urine flow (P less than 0.02 and P less than 0.05, respectively), and in sodium excretion (P less than 0.05 and P less than

8. Fetal echogenic gut: a marker of intrauterine gut ischaemia?
The pathophysiological significance of fetal echogenic gut (FEG) is unknown. Our aim was prospectively to evaluate FEG in infants with intrauterine growth retardation (IUGR) and absent umbilical artery end diastolic flow velocities. Over a 15 month period, nine infants with FEG met these criteria. Nine infants who, on antenatal assessment, had demonstrated I

9. In utero right ventricular output in the fetal lamb: the effect of heart rate.
1. The effect of heart rate on right ventricular output was examined in six lambs during a period extending from 126 to 139 days of gestation. The fetuses had been surgically instrumented at least four days previously with a main pulmonary artery flow probe, right ventricular dimension transducers and left and right atrial pacing electrodes. 2. During sponta

10. M mode and Doppler echocardiographic assessment of left ventricular diastolic function in primary antiphospholipid syndrome.
BACKGROUND--High titres of serum antiphospholipid antibodies are a possible pathogenic factor for cardiac lesions in patients with systemic lupus erythematosus. OBJECTIVE--To test the hypothesis of a causal link between high titres of antiphospholipid antibodies in the serum and myocardial involvement in patients without systemic lupus erythematosus. PATIENT
