background: different studies show that chromosomal balance translocation in the parents can cause recurrent spontaneous abortions. incidence of chromosomal translocation abnormalities in couples with repeated abortions is from 0% to 31%. objective: the purpose of this research was studying the presence or absence of chromosomal abnormalities and heteromorphism in couples with recurrent abortio...

Objective: Approximately 15-20% of clinically recognizable pregnancies end in spontaneous abortion. The incidence of chromosomal abnormalities in those abortions is as high as 50%.A modest but clinically important proportion of spontaneous abortions is caused by a balanced chromosomal aberration in one o...

Background: The role of apolipoprotien E polymorphisms do not diagnostic correctly in recurrent pregnancy loss etiology but Apo E has been shown to play an important role in lipid metabolism in pregnancy. We evaluated these polymorphisms in Iranian women with unexplained recurrent pregnancy loss. Materials and Methods: 5 ml Blood were sampling from 81 women with a history of two or more consecu...

A number of cases of unexplained (idiopathic) recurrent spontaneous abortions may be attributable to immunological mechanisms. Several lines of evidence indicate that some immunocompetent effector cell populations play an important role in the pathogenesis of unexplained miscarriages. However a suitable method is lacking for defining an existing immunological background of recurrent spontaneous...

objective: approximately 15-20% of clinically recognizable pregnancies end in spontaneous abortion. the incidence of chromosomal abnormalities in those abortions is as high as 50%.a modest but clinically important proportion of spontaneous abortions is caused by a balanced chromosomal aberration in one of the parents. this results from the production of gametes and embryos with unbalanced chrom...

objective: this study determined the chromosomal constitution of recurrent spontaneous abortions by comparative genomic hybridization (cgh) analysis of fetal samples. material and methods:   forty pregnant women with early recurrent pregnancy losses aged 21 to 42 years old from tehran university of medical sciences affiliated hospitals entered in this descriptive study. hibridization analysis o...

OBJECTIVE Adenosine deaminase acts on adenosine and deoxyadenosine metabolism and modulates the immune response. The adenosine deaminase G22A polymorphism (20q.11.33) influences the level of adenosine deaminase enzyme expression, which seems to play a key role in maintaining pregnancy. The adenosine deaminase 2 phenotype has been associated with a protective effect against recurrent spontaneous...
