It was aimed in this study that the morphometric development of the hand in human fetuses throughout the fetal period be radiologically investigated and the clinical importance of this period be evaluated. A total of 50 fetuses with no external pathology or anomaly, and the ages of which varied between 20-40 gestational weeks were incorporated into the study. The fetuses were separated into groups according to gestational weeks, trimesters and months. After the general external measurements of the fetuses were performed, mammography and hand radiographies of the fetuses were shot in the way that their hands would be in a pronational position. Afterwards, the morphometric measurements of the hands were performed with the help of a digital caliper through...

Provedor de dados: 77
Autores: Pórtela,Gabriela Soares; Azoubel,Reinaldo; Batigália,Fernando.
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) to receive 14 mg/kg aspartame or water by oral-gastric drip. Treated Tl: aspartame diluted in water at room temperature; Treated T2: aspartame diluted in water heated to 40° C; control Cl: water at room temperature; and control C2: water heated to 40° C. Placentas were weighed, umbilical cords measured and 1000 nuclei of fetal hepatocytes (250 from each group) were analyzed morphometrically utilizing the technique of kariometry, with application of the...

Provedor de dados: 77
Autores: Desdicioglu,Raziye; Uguz,Ceren; Desdicioglu,Kadir; Sulak,Osman; Malas,Mehmet Ali.
Fetal period of time during which the fetus grows rapidly and the organs are formed. The prenatal and postnatal analyses of the fetal structure provide information as to fetal growth, growth retardation, gestational age and congenital malformations. The development of the skeletal system during the intrauterine period takes place in an orderly manner as it also does in other systems. It was aimed that the morphometric development of the forearm in human fetuses during the period between 20-40 gestational weeks be radiologically investigated and that its clinical importance be evaluated, as well. A total of 100 fetal forearms (50 fetuses: 23 male, 27 female), the ages of which varied between 20-40 gestational weeks, without having any external pathology or...

Effects of Sucralose Ingestion on Fetal and Placental Weights and Umbilical-Cord Length: Experimental Study
Provedor de dados: 77
Autores: Rodero,Ademir B; Batigália,Fernando; Azoubel,Reinaldo; Moura,Arianne Assis; Rodero,Lucas de Souza; Silveira Jr,Landulfo.
Sucralose is a sweetener of general use in over three thousand products (beverages, foods and medical diets), with utilization currently permitted for the general population in more than 80 countries, including for women of reproductive age. There is little information on the safe use of sucralose, and experimental studies have suggested that the administration of some sweeteners, by diverse routes, retards not only fetal and placental development but also umbilical cord size. The present study aimed to estimate the fetal and placental weights and umbilical-cord length in fetuses from rat dams, after ingestion and non-ingestion of sucralose. In the treated group (5 dams), sucralose was administered (via gavage) at the dose of 30 mg/kg/day, from the 10th to...

EFFECTS OF ACETYLSALICYLIC ACID ON ETHANOL-INDUCED INTRAUTERINE GROWTH RESTRICTION IN RATS
Provedor de dados: 77
Autores: Aparecida Marinho,Sandra; Sala,Miguel Angel; Lopes,Ruberval Armando; de Moraes Grisi,Márcio Fernando; Belém Novaes Jr.,Arthur; Scombatti de Souza,Sérgio Luis; Taba Jr.,Mário.
SUMMARY: The effects of acetylsalicylic acid (ASA) on intrauterine growth restriction induced by maternal ethanol consumption were studied. A single intraperitoneal dose of ethanol (2.96 g/kg body weight), injected on the 10th day of pregnancy (PD10), significantly reduced maternal weight gain, fetal weight, amniotic fluid volume and umbilical cord length. Meanwhile, ethanol did not affect placental weight or litter size. A single intraperitoneal dose of ASA (200 mg/g body weight), injected on the PD10, did not modify maternal body weight gain, litter size, fetal and placental weights and amniotic fluid volume, but significantly diminished umbilical cord length. Intraperitoneal injections of either ASA (200 mg/g body weight) or ethanol (2.96 g/kg body...

Provedor de dados: 77
Autores: Leme,Fabíola Azevedo Genovez de Lima; Azoubel,Reinaldo.
The present study evaluated the effects of the sweetener aspartame on the fetal pancreas, through a morphometric study, with the objective of studying the exocrine pancreas at the end of gestational development. For this we utilized two treated groups, one with a solution of aspartame at ambient temperature and the other with an aspartame solution heated to 40C, and two groups treated with water ad libitum, at ambient temperature and heated to 40C, respectively. On the final day of gestation the fetuses were removed and the pancreas was collected for microscopic analysis. The morphometric study demonstrated alteration in eight out of the eleven parameters studied in the group treated with the heated solution and one parameter altered in the group treated...

Gross Anatomical Studies on the Adrenal Gland in Prenatal Goat (Capra hircus)
Provedor de dados: 77
Autores: Pathak,Satish K; Farooqui,M. M; Kumar,Prabhakar; Prakash,Ajay; Pathak,Archana; Singh,Dharmendra.
The present study was conducted on the 24 healthy and normal embryos/foeti of non- descript goat (Capra hircus) varying from day old to 150 days of gestation. The embryo/foeti were assigned into three groups according to their gestational ages; Groups I (0-50 days), II (51-100 days) and III (101-till term). At 38 days of gestation the primordia of right and left adrenal gland were observed as a pea shaped spherical swelling located just cranial to the respective metanephros. Biometrical studies revealed the increase in the all parameters of the adrenal gland with the advancement of age. Adrenal glands were harvested first grossly at 50 days of gestation.

三次元超音波検査法の小動物臨床への応用の可能性を探求するために，妊娠後期の6 歳 のビーグル犬に対して，腹部用三次元プローブを用いた三次元超音波検査法を出産まで数 日毎に行い，8 頭の胎子の顔を描出しようと試みた。胎子の顔の三次元超音波画像が全ての 検査日において少なくとも1 頭の胎子で得られたが，胎子が成長するにつれて良好な画像 を得るのは難しくなった。交配後43 日目ならびに45 日目では胎子の顔の鮮明な三次元画 像が容易に得られた。技術的に解決しなければならない問題がいくつか残されているもの の，適切に用いさえすれば，三次元超音波検査法は従来の二次元超音波検査法を補足する 方法として小動物臨床に応用可能であると考えられる。 This study was delineated to explore the possibility of using three-dimensional ultrasonography in small animal practice. In a 6-year-old pregnant beagle bitch with eight feti, we tried to visualize the feti faces with three-dimensional ultrasonography by scanning with a transabdominal three-dimensional probe every two to three days until parturition. At each date of examination, Three-dimensional sonographic images of the feti faces were...

Recent advances in sow nutrition
Provedor de dados: 96
Autores: Kim,Sung Woo.
Sows produce a larger number of fetuses than before and these fetuses possess genetic potentials to grow faster than before. Recent comparison shows that a porcine fetus is 40% heavier than 40 years ago. Thus the nutritional management of sows has been updated to reflect these genetic changes. Our recent study quantified nutritional needs for sows to support the growth of fetuses and mammary glands during gestation. Amino acid needs for fetal growth and mammary growth during late gestation (d 70 to farrowing) significantly greater than those needs during early gestation (until d 70). Considering these increases, daily requirement of true ileal digestible Lys for a primiparous sows increases from 7 g (until d 70) to 15 g (d 70 to farrowing). Required...

Provedor de dados: 3
Autores: Tavares Vieira, Kátia Cristina de Melo; Couto, Jennifer Cardoso; Zanetti, Edson; Sanches Junior, José Marcos; Favareto, Ana Paula Alves.
Metolachlor is a selective pre-emergent herbicide widely used in agriculture to control weeds. The aim of this study was to evaluate the possible effects of metolachlor on reproductive performance of adult rats, as well as its teratogenic potential when administered during the period of organogenesis. Pregnant adult female rats were allocated into 4 experimental groups (n = 10 group-1), that received 0 (control); 150 (TA); 300 (TB); or 1000 mg kg-1 bw day-1 (TC) of metolachlor, by gavage, from the 6th to 15th gestational day (GD). There is reduction in the weight gain of the animals from TB and TC groups compared to the control group. Liver and placenta weights were reduced in TB and TC groups, respectively, while the percentage of post-implantation loss...

Abortion in association with transplacental Theileria equi infection in a mare from the State of Espírito Santo, southeast Brazil: case report
Provedor de dados: 45
Autores: Oliveira,A.R.; Pinheiro,G.R.G.; Souza,T.D.; Flecher,M.C.; Santos,R.L.
ABSTRACT Equine piroplasmosis is a tick-borne disease caused by the protozoan parasites Babesia caballi and Theileria equi. We report a case of abortion in association with transplacental Theileria equi infection in a mare from the State of Espírito Santo, southeast Brazil. An apparently healthy mare aborted at the tenth month of gestation. At necropsy, the subcutaneous tissue, skeletal muscles, and visible mucosae of the aborted fetus were pale, and there was moderate hydrothorax and marked splenomegaly. Microscopic findings included splenic lymphoid hyperplasia and nephrosis. Merozoite-infected erythrocytes were found within blood vessels of all organs examined and were most numerous in the brain. DNA extracted from the spleen, liver, kidney, and thymus...

Development of fetal nicotine and muscarinic receptors in utero
Provedor de dados: 56
Autores: Mao,C.; Lv,J.; Li,H.; Chen,Y.; Wu,J.; Xu,Z.
The role of acetylcholine in the central and peripheral nervous systems is well established in adults. Cholinergic modulation of vascular functions and body fluid balance has been extensively studied. In the embryo-fetus, cholinergic receptors are widespread in the peripheral and central systems, including smooth muscle and the epithelial lining of the cardiovascular, digestive, and urinary systems, as well as in the brain. Fetal nicotine and muscarinic receptors develop in a pattern (e.g., amount and distribution) related to gestational periods. Cholinergic mechanisms have been found to be relatively intact and functional in the control of vascular homeostasis during fetal life in utero at least during the last third of gestation. This review focuses on...

Effect of strenuous maternal exercise before and during pregnancy on rat progeny renal function
Provedor de dados: 56
Autores: Oliveira,A.O.; Fileto,C.; Melis,M.S.
The effects of strenuous exercise before and during pregnancy on the renal function and morphological alterations of the progeny were determined in a study on female Wistar rats. This research was done based on a previous study carried out in our laboratory, which showed morphological alterations in rats submitted to this kind of exercise. As the form is related to the function, the physiological relevance of submitting a pregnant female to a high-intensity exercise training regimen could be explained by the fact that morphological alterations can influence kidney function. The animals were assigned to one of two groups: control animals that did not exercise during pregnancy and trained animals that swam for 120 min 5 days a week for 8 weeks before...

Provedor de dados: 65
Autores: Silva,Elisa Sant'Anna Monteiro da; Pantoja,José Carlos de Figueiredo; Puoli,José Nicolau Próspero; Meira,Cezinande.
The present study evaluated the development of equine conceptus transferred to non-cyclic recipient mares treated with altrenogest. Twenty four mares were used as embryo recipients during the ovulatory phase (Control group; n=8) or anestrus/transitional phases (Altrenogest group; n=16) and were evaluated by transrectal ultrasonography, at five day intervals, to monitor the development of embryonic vesicles from 15 to 45 days of pregnancy and embryo proper/fetus from 20 to 60 days. Embryonic vesicle's features such as shape, embryo location within the vesicle and umbilical cord development were similar between cyclic and non-cyclic recipient mares. The embryonic vesicle and embryo proper/fetus growth was significant (P&lt;0.05) between 15 and 60 days of...
