1. Evaluation of Dietary Supplement Intake (Yeast Tablets) on Pregnant Albino Rats and Their Fetuses (Implications of Yeast Tablets on Rats & Fetuses)
ABSTRACT Histopathological studies in placenta, liver, kidney, apoptotic DNA damage and p53 mutation estimation of pregnant rats and their offspring exposed to dietary supplement yeast tablets, were carried out. Pregnant female albino rats were orally administrated yeast tablets at concentration 41.1 mg/kg during gestation period. Hematoxylin and eosin stain

2. Low-protein diet does not alter reproductive, biochemical, and hematological parameters in pregnant Wistar rats
The aim of this study was to investigate the reproductive, biochemical, and hematological outcomes of pregnant rats exposed to protein restriction. Wistar rat dams were fed a control normal-protein (NP, 17% protein, n=8) or a low-protein (LP, 8% protein, n=14) diet from the 1st to the 20th day of pregnancy. On the 20th day, the clinical signs of toxicity wer

3. Rats treated with Hypericum perforatum during pregnancy generate offspring with behavioral changes in adulthood
Abstract Drugs used in the treatment of depression can cross the placenta giving rise to questions regarding the effects these drugs exert on the fetus. Hypericum perforatum L., Hypericaceae, is a natural product used to treat depression. However, information about its toxicity and the occurrence of alterations in the central nervous system development of th

4. Implications arising from the use of Cymbopogen proximus ; proximal on placenta of pregnant Albino rats
ABSTRACT Halfa-bar (Cymbopogon proximus), is an aromatic grass widely growing in Upper Egypt. This herb is recommended for medical purposes as an effective diuretic, renal or abdominal antispasmodic agent. Objectives of this study: Evaluate the potential effects of Halfa-bar on the pregnant albino rats during the gestation period. Material and methods: The v

5. Maternal exposure to Cochlospermum regium: a toxicological evaluation
Cochlospermum regium (Schrank) Pilg., Bixaceae, is a Brazilian plant widely used as a folk medicine in the southwestern of the Brazil to treat inflammation and infection diseases. However, the effects of C. regium hydroethanolic extract on pregnant rats have not been assessed. To evaluate the effects of the C. regium on pregnant rats during the organogenic p

6. Efeito da ingestão crônica de dieta hiperlipídica no metabolismo de ratas, e sobre a expressão de SR-BI e ABCA1 na placenta, intestino delgado, fígado e rins da prole destes animais = : Effect of high fat diet chronic ingestion on the metabolism of female rats, and on the SR-BI and ABCA1 expression in the placenta, small intestine, liver and kidney of the offspring / Effect of high fat diet chronic ingestion on the metabolism of female rats, and on the SR-BI and ABCA1 expression in the placenta, small intestine, liver and kidney of the offspring
Devido ao maior consumo de alimentos ricos em gordura e um estilo de vida mais sedentário, houve um aumento na incidência de desordens metabólicas relacionadas ao metabolismo lipídico como a resistência à insulina, dislipidemias, e sua associação com doenças cardiovasculares. A alimentação materna desequilibrada, durante a gestação e lactação,

7. Sobrecarga de sal durante a gestação: efeito sobre o sistema renina angiotensiva sistêmico e renal da prole adulta de ratos Wistar / Salt overload during perinatal life: effect on the systemic and local renin-angiotensin system in adult offspring Wistar rats
O aporte de nutrientes ingerido pela mãe durante a gestação e o transporte dos nutrientes da placenta para o feto são essenciais para o crescimento fetal. A sobrecarga de sódio durante a gestação tem demonstrado ser um dos fatores responsáveis pela hipertensão na vida adulta da prole. Um estudo anterior em nosso laboratório demonstrou que além do

8. Study of the alterations in the development, behavior and cerebral biochemistry of male rats exposed to the environmental atmospheric pollution in the intra-uterine phase / Estudo das alterações no desenvolvimento, no comportamento e na bioquímica cerebral de ratos machos adultos expostos à poluição atmosférica ambiental durante a fase intra-uterina e o período de lactação
Experimental studies done at our laboratory demonstrated that the inhalation of residual oil fly ash by the adult rats decreased motor activity of the animals in the open-field test. Additionaly, we showed that rats which inhalated residual oil fly ash preserved its habituation capacity. In this study, oxidative stress in striatum and cerebellum might be the

9. Placentação em roedores da família Cricetidae - Sigmodontinae / Placentation in rodents of family Cricetidae Sigmodontinae
Placenta is found only in mammals and it is result of the success of blastocyst implantation in the uterus, representing a functional organ to maternal-fetal exchanges and it is also an important endocrine organ. The Family Cricetidae and Subfamily Sigmodontinae include the rats and mice from South America. Due to the similarity of both the placenta morpholo

10. Efeitos do ciclamato de sódio e do aspartame na placenta de uma ratas: estudo morfométrico
To evaluate the effects on the placenta of the administration to rats during embryogenesis, of sodium cyclamate or aspartame. Method: Administration of respectively, 14 mg/kg of aspartame via an orogastric sound to a group of rats during their tenth to fourteenth day of pregnancy, of 60 mg/Kg of sodium cyclamate intraperitonially to another group, and of equ

11. Associação entre crescimento neoplasico e gravidez : estudo do perfil hormonal e alterações placentarias em ratas prenhes potadoras do carcinossarcoma de walker 256 / Neoplasic growth and pregnancy : hormonal profile and placental alterations in pregnant tumor-bearing rats
A gravidez gera modificações no organismo materno para a implantação do blastocisto, que são provocadas por hormônios como estradiol e progesterona. O tempo e curso de gravidez dependem da unidade materno / fetal, a placenta, que é o órgão responsável pela trocas entre mãe e feto, além de secretar vários hormônios, dentre eles prolactina, estr�

12. Ultrastructural and immunohistochemical study of the influence of fluoride excess on the development of rat incisor tooth buds
Little information is available on the pathogenesis of fluorosis during the fetal and initial postnatal period. In the present study, female rats received 0 (control), 7 or 100 ppm of sodium fluoride in drinking water, one week before breeding and throughout gestation and nursing periods. The hemimandibles of the offspring were collected at 0, 7 and 14 days
