RESEARCH STUDY
The purpose is to study the structural features of the tissues (placenta, umbilical cord and uterus) and the characteristics of erythrocytes in mother-placenta-fetus system during pregnancy with thyroid gland pathology of various genesis, diabetes type 1 and gestational diabetes mellitus (GDM), moderate and severe pre-eclampsia degrees.
MATERIALS AND METHODS
The material for examination was 117 pregnant women, among whom 65 women with thyroid gland pathology, 27 women with diabetes mellitus of various genesis, 15 women with pre-eclampsia and 10 women of the control group. All women were examined with ultrasound test (Alokka-5500 machine), evaluated the levels of triiodothyronine and total thyroxine, free thyroxine, thyroid hormone and the level of thyroglobulin antibodies, glucose, including performed glucose tolerance test. In addition, we performed morphometric analysis of the tissues in the Ntegra-Aura machine and atomic force microscopy using the standard software NOVA (NT-MDT) and ImageAnalysis (NT-MDT).
RESULTS
The study of placenta and myometrium vessels revealed various circulatory problems: edge standing of red blood cells, stasis, sludge, hemolysis, endotheliocyte disconnections, and impairment of endothelial microrelief. During the study of terminal branches, we found that the villi surface and the vessel area were reduced in the sequence: GDM, euthyroid mother with thyroid pathology, hypothyroidism, diffuse toxic goiter, pre-eclampsia, and diabetes. Test revealed a significant increase deformation of red blood cells.
CONCLUSION
As a result, we noted that the pathology of thyroid gland, diabetes type 1 and pre-eclampsia deformed the structure of the mother-placenta-fetus system provoked multiple microstructural changes in tissues up with combination the anatomical and functional changes of red blood cells leading to further progression of fetal hypoxia.
