Human Leukocyte Antigens (HLA) of fetus are responsible for induction of HLA antibodies in mother. Exposure to the mismatched paternal HLA antigens in the fetus gives rise to a polyclonal antibody response against paternal HLA antigens. HLA antibodies are present in the maternal circulation of the placenta and are absorbed onto the placenta [1]. The major source of HLA antisera is from sera of ...

Background: Approximately 3% to 5% of obstetric patients will experience postpartum hemorrhage (PPH). Even though the most common reason for postpartum hemorrhage, as the main cause of maternal death, is uterine atony; other complications such as laceration, hematoma, inversion, rupture; retained tissue or invasive placenta; and coagulopathy may result in PPH. The main cause of retained placent...

the placental adhesive disorders such as placenta accreta and placenta percreta are the rare causes of serious obstetric hemorrhages. they are associated with high maternal morbidity and mortality. placenta percreta is usually diagnosed in the third trimester of pregnancy as a massive postpartum hemorrhage when an attempt to remove the placenta reveals lack of a cleavage plane. here we report a...

introduction: lansoprazole is one of the proton pump inhibitor drugs widely used in the treatment of gastro-duodenal ulcers and disorders. however, there is not enough data about unexplored adverse effects of lansoprazole on the integrity of the placental barrier. therefore, the present study was conducted to determine whether placental structure could be affected by lansoprazole administration...

introduction: the use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. in this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.   materials and methods: for this work, 40 pregnant balb/c mice were randomly allocated to one c...

To investigate the effects of certain factors on the rate of retained placenta, 2844 calving records from 1288 Holstein cows in a herd were used. These cows calved during year period of 2001 to 2007. A generalized statistical linear model was applied to analyze the data. Logistic regression model was applied as the statistical model. In the model, fixed effects of year, season (warm or cold) an...

background: abnormal placental invasion has increased parallel with persistent rise in caesarean delivery. management relies on accurate diagnosis and delivery should be planned at an institution with appropriate expertise and resources for managing this condition.   case: we present a case of a placenta invasion anomaly which is the major risk factors of peripartum deaths. in this case we try ...
