Int. j. morphol; 38 (5), 2020
SUMMARY: Studies in humans showed that prenatal exposure to urban air pollution (AP) influences fetal development, and increases the incidence of adverse pregnancy outcomes and some diseases in postnatal life. However, most of these were performed in environments where the main source of environmental pa...

Does Enoxaparin treatment have any effects on the placenta in women with unexplained histories of habitual abortion? A case control study

Säo Paulo med. j; 138 (4), 2020
ABSTRACT BACKGROUND: It is very common to offer low molecular weight heparin (LMWH) medications to women with unexplained habitual abortion, to increase the livebirth rate. Although no benefit from LMWH has been clearly demonstrated, examination of the effects of enoxaparin on placental structure is la...

Morphological alterations in mouse placenta induced by diazepam

Int. j. morphol; 32 (2), 2014
Diazepam (DZ) is a benzodiazepine that belongs to the group of minor tranquilizers with myo-relaxing and anticonvulsant properties. DZ and its metabolites cross the placental barrier in human, monkey, hamster, and mouse, and accumulate in the placenta. Our aim was to investigate, through histological tec...

Effects of Aspartame on Maternal-Fetal and Placental Weights, Length of Umbilical Cord and Fetal Liver: A Kariometric Experimental Study

Int. j. morphol; 25 (3), 2007
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)...

Ação crônica do napsilato de propoxifeno na prenhez da rata
Chronic effects of propoxyphene napsylate on pregnant rats

O objetivo deste trabalho é avaliar os efeitos do napsilato de propoxifeno sobre a prenhez da rata albina. Para tanto utilizamos 50 ratas prenhes divididas ao acaso em cinco grupos iguais. Todas receberam diariamente, por gavagem, o volume de 1 ml, desde os dias 0 (zero) até o 20 de prenhez, com as seg...

Effect of insulin therapy in on pregnancy of diabetic rats: fetal and placental repercussions

O objetivo deste trabalho foi estudar as repercussoes feto-placentárias da insulinoterapia na prenhez de ratas diabéticas. A droga diabetogênica foi aloxana na dose de 42 mg/kg de peso por via intravenosa. Formaram-se cinco grupos experimentais: controle (G1, n=12); diabete moderado nao-tratado (G2, n...

Effects of low-dose exposure of rat fetuses pancreas to methylmercury: morphometric and stereologic studies

Rev. chil. anat; 16 (2), 1998
El cloruro de metilmercurio (20 mg/kg de peso corporal), cuando fue administrado oralmente a ratas Wistar en el día 10 de la preñez, dio origen a fetos y placentas de menor peso. Hubo muerte y reabsorción fetal, a pesar de no existir malformaciones macroscópicas. Histológicamente, los acinos pancreÃ...

Estudio morfológico de la lengua de fetos de ratas intoxicadas con niquel durante la preñez
Morphologic study of the tongue of intoxicated rat fetuses with nickel during pregnacy

Rev. chil. anat; 14 (1), 1996
El cloruro de níquel (30 mg/kg de peso corporal), administrado intraperitonealmente, a ratas wistar, en el 10º día de la preñez, dio origen a fetos y placentas menores y a cordones umbilicales más cortos. Histológicamente, el epitelio lingual anterior fue más grueso, con células más grandes y en...
