background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...

Peripheral blood NK cells seem to be strongly related with decidual NK cells, and may reflect the decidual NK cell functional status.

background: recurrent spontaneous abortion is one of the diseases that can lead to physical, psychological, and, economical problems for both individuals and society. recently a few numbers of genetic polymorphisms in kinase insert domain-containing receptor (kdr) gene are examined that can endanger the life of the fetus in pregnant women. objective: the risk of kdr gene polymorphisms was inves...

Background: Recurrent spontaneous abortion (RSA) is defined as three or more se-quential abortions before the twentieth week of gestation. There are evidences to sup-port an allo-immunologic mechanism for RSA. One of the methods for treatment of RSA is leukocyte therapy; however there is still controversy about effectiveness of this method. Objectives: To evaluate the effectiveness of leukocyte...

background: approximately 10-14% of the clinically acknowledged pregnancies end with spontaneous abortion at caucasian population. possible immunologic causes of recurrent miscarriages have been extensively researched. the change in the cytokines balance synthesis in favor of those synthesized by th2 cells with an increase of interleukin 6 (il6) and interleukin10 (il10) secretion is considered ...

Background Spontaneous abortion has been defined as two or more consecutive miscarriages at 20 weeks pregnancy. Vascular endothelial growth factor (VEGF) plays a main role in fetal and placental angiogenesis which secretes from different cells like endometrium and placenta.The objective of this study was to investigate of association of VEGFA gene polymorphisms and recurrent spontaneous abortio...

BACKGROUND: Several humoral immune factors are responsible for a successful pregnancy. There are a few studies, which demonstrate the role of antipaternal cytotoxic antibodies (APCA) and mixed lymphocyte reaction blocking factor (MLR-Bf) in the maintenance of pregnancy. However, these factors have not been studied in women with history of recurrent spontaneous abortion (RSA). We designed this s...

one of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. we report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. chromosomal studies were performed on the basis of g-banding technique at high resolution and revealed 46, xx, t (16 6) (p12 q26) and 46, x...
