[Production and reception of growth factors in the placenta during physiological and gestosis complicated pregnancy].
30 women with physiological pregnancy and 28 women with gestosis were examined. In the early chorion obtained after abortion and on the full-term placenta the content of the epidermal growth factor (EGF), vascular-endothelial growth factor (VEGF) and their receptors were studied by means of the ELISA method. In the process of normal gestation the increase of the placental production both of the EGF and VEGF was found. During the pregnancy complicated with gestosis and miscarriage in the first trimester the content of EGF and its receptor was lower compared to the physiological values. For VEGF and its receptor opposite changes were found: the increase of quantity of the growth factor and the decrease of its receptor. In the case of gestosis and term pregnancy the content of the both growth factors and their receptors was lower than in controls. The revealed changes in production of the angiogenic growth factors and their receptors in the placenta may have the pathogenic importance in the development of gestosis.
