title: [Evaluation of the morphology of the human placental cotyledon following dual in vitro perfusion in variable magnetic field].
abstract: Objectives and the aim of the study was electron-microscopy morphological estimation of the human placental cotyledon after 180 minutes of dual closed perfusion in vitro.
  
  
  METHODS
  In the experimental group the cotyledons were exposed to variable magnetic field of 2 mT magnetic induction and 50 Hz frequency. The control group K (10 perfusions) was not subjected to magnetic field while the experimental group B (10 perfusions) was influenced by magnetic field.
  
  
  RESULTS
  It was found that homogeneous variable magnetic field disturbs the ultrastructure of the nuclei and cytoplasma and it increases the density of the vascular-epithelial membrane of villi cells of human placenta in vitro.
  
  
  CONCLUSIONS
  Variable sinusoildal, magnetic field of 2 mT magnetic induction and 50 Hz frequency disturbs the ultrastructure of the nuclei and cytoplasma and it increases the density of the vascular-epithelial membrane of villi cells of human placenta in vitro after 180 minutes of dual closed perfusion in vitro.
