Abstract Objectives: This study aimed to analyze, through the morphometric method, the perimeter and length of the tongue, the collagen fibers, and the perimeter of blood vessels at different gestational ages and fetal weights. Material and methods: Tongues (n = 55) of stillborns autopsied at 23-40 wee...

Abstract Objective To assess 11 formulae commonly used to estimate fetal weight in a population of premature fetuses who had abnormal Doppler velocimetry due to early-onset placental insufficiency. The performance of each formula was evaluated in subgroups of fetuses with expected growth and intrauteri...
Abstract Purpose: To evaluate the effects of oxidative stress in pregnant rats submitted to acute and chronic stress, relating to alterations in the uterus, placenta and fetus. Methods: Twenty-four female Wistar albino (Rattus norvegicus), were divided into four groups, for induction of oxidative str...

ABSTRACT This study aimed to evaluate the teratogenic and hepatotoxic potential of the usnic acid encapsulated into PLGA-microspheres. In total, 12 female Wistar rats in pregnancy were randomly distributed in the control group (n= 6) that received 1.0 mL of physiological solution and treatment group (n= ...

ABSTRACT Objectives To confirm if a real inner descend of testis occurs, correlating the testicular position with fetal parameters and analyzing the position of the testes relative to the internal ring. Material and Methods Twenty nine human fetuses between 13 and 23 weeks post conception (WPC) were ...

OBJECTIVE: To determine the correlation of ultrasonographic estimation of fetal weight and actual birthweight and the impact of the level of resident s training on the results. METHODS: This was a prospective study of 90 women with term pregnancies. Ultrasound estimated fetal weight (EFW) was calculated ...
La ecografía obstétrica se ha posicionado como un apoyo importante al control prenatal, incluso por matronas y médicos generales que controlan pacientes en atención primaria. Sin embargo, la disponibilidad de ecografía realizada por médico obstetra en el sistema público es relativamente escasa, l...
Aspartame is a synthetic sweetener consumed by more than half the adult population in 75 countries. Their metabolites can be toxic, principally to the liver and retina, and there are few studies on the use of aspartame in gestation. Twenty pregnant rats were weighed and allocated randomly (n=5 per group)...

A estimativa do peso fetal pela ultra-sonografia é importante para se verificar o bem estar do feto, avaliar a evolução de seu crescimento no decorrer da gestação e também para reduzir a morbidade e mortalidade associadas a desvios do crescimento intra-útero. O termo macrossomia é utilizado para ...
