UNLABELLED Preeclampsia is one of the most frequent and dangerous complications of a pregnancy. In preeclamptic pregnancies the spiral arteries are not modified properly. Disturbed blood flow finally leads to hypoxia which is responsible for the dysfunction of the endothelium. Endothelial growth factor (VEGF) and placental growth factor (PIGF) play an(More)
The development of pregnancy is possible due to initiation of immune response in the body of the mother resulting in immune tolerance. Miscarriage may be caused by the impaired maternal immune response to paternal alloantigens located on the surface of trophoblast and fetal cells. The aim of the study was to compare the population of circulating dendritic(More)
Preterm labor remains to be one of the most important challenges of contemporary perinatology and constitutes the main reason of perinatal mortality and prematurity of neonates. Studies on preterm labor have confirmed the mutual interactions of several different hormonal systems while the activation of hypothalamic-pituitary-adrenal axis seems to have the(More)
Cystic fibrosis (CF) is the most common autosomal recessive disorder in Caucasian population that involves the lungs, pancreas, sweat glands, intestine, liver and reproductive tract. The majority of men with CF are infertile due to a bilateral congenital absence of the vas deferens (CBAVD). The purpose of the research was to evaluate the occurrence(More)
INTRODUCTION Pathomechanism of intrauterine growth restriction is a complex issue, involving many different factors, and is still undergoing an investigation. Improper placental angiogenesis, resulting in placental pathology, is considered to be one of the most important causes of IUGR. Placental vascular growth factors--placental growth factor (PIGF),(More)
Reported are 304 patients with whom programmed childbirths were introduced, between 1976 and 1978. A control group was made up of 100 women in labour who had been hospitalised for spontaneous onset of labour but then given slow drip oxytocin infusions for secondary uterine inertia. The parameters tested (time of labour, FHF behaviour, pH of umbilical(More)
To prove the importance of anxiety as a disturbing factor during invasive sterility therapy 87 women of an IVF- and GIFT-series were investigated by a standardized anxiety inventory. We could not find any direct relations between breaking off stimulation and a striking level of anxiety. The role of anxiety as a co-factor in the different kinds of sterility(More)
BACKGROUND Mesenchymal stromal cells, MSCs, show expression of specific antigens on their surface. The aim of the study is to assess the phenotype of stem cells like isolated from the umbilical cord with respect to the presence of surface antigens CD34, CD90, and CD105 and differences in the expression of surface antigens in cells isolated from freshly(More)
In the present paper we will report on a pregnancy following a Gamete Intra Fallopian Transfer (GIFT). This is a 26 years old female, treated in our sterility dispensaire for a secondary sterility since 1982. All basic hormone levels were normal. The andrological examination of her husband showed an oligozoospermia stage 2. A following hormone treatment was(More)
