PURPOSE To reproduce the experimental model of gastroschisis in chicken embryos and to prove that the histopathological changes that occur in this model can be compared to those in human gastroschisis. METHODS A total of 278 Leghorn hen (Gallus domesticus) eggs were used. The embryos were divided into three groups: the gastroschisis group, in which the umbilical cord was opened through an ori...

Introduction: Metritis is one of the causes of maternal morbidity and there are many risk factors for it. Because of the importance of possible association of meconium-stained amniotic fluid and maternal metritis the present study was done to determine whether meconium stained amniotic fluid (MSAF) is associated with puerperal infection. Methods: In this case-control study 150 women with MSAF a...

objective: in recent years, amino acids are used in veterinary medicine for many purposes. they injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. there is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. the objective of this st...

pathogens are an important and significant hazard for human and animal health. in recent years, antibiotics are used to treat different types of infection caused by bacterial agents. in veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. there is scan...

In the 18th week of pregnancy in a 22 year old patient, twins were diagnosed by ultrasound. It was found that one twin had an abnormal skull outline and an echo-free area covered by a thin membrane in the region of the abdomen. The second embryo showed no sign of malformation. Amniocentesis was performed and the AFP in both samples of amniotic fluid were in the pathological range. Our own obser...

objective: in recent years, antiviral drugs have been used widely in the glob to prevent and treat viral diseases. they injected into eggs to eliminate pathogens and prevent of egg transmission of disease, but the adverse effects of drugs have always been a major concern. there is little information available about the safety of antiviral drugs in the embryonated eggs of birds. the objective of...

Variation in the amount and quality of influenza virus injected into the amniotic sac of the chick embryo led to differences not only in the yield of virus but also in the immunofluorescent cytology of the infection. The production of infectious virus was associated with a predominance of cells in which the virus antigens were first detected along the cell surface in contact with the amniotic f...

Introduction: meconium is the thick, Green - Black, with a bad odor material,  that founded around the third month of pregnancy in the intestines of fetus. 8 to 15 percent of infants has the evidence of meconium stained fluid at birth. In this study the factors affecting maternal and neonatal meconium-stained amniotic fluid be examined. Methods: This study was done in the Vali-e- asr hospital ...

Distribution of water and of Na+ and Clions in blood and in allantoic, amniotic, and yolk sac fluids were observed during ontogeny of the chick embryo. A possible osmoregulatory role for pituitary hormones was inferred from differences in ionic concentrations and volumes of these compartments in partially decapitated (hypophysectomized) embryos and in intact and windowed-control embryos observe...

Experiments were carried out with the suckling mouse cataract agent (SMCA) in an attempt to better characterize the nature of this agent. Despite the fact that high titers of SMCA were found in the chorioallantoic fluid of inoculated chicken embryos, the agent did not replicate in chicken embryo epithelial cell cultures. SMCA did not interfere with Sindbis virus plaque formation and was not inh...
