ABSTRACT
OBJECTIVE:
to investigate morphological changes in the primary thyroid cell culture of rat infants whose parents were prenatally exposed by radioisotope iodine 131. MATERIALS ANDMETHODS:
obtaining and culturing of thyroid tissue primary cell cultures of newborn rats, cytological (receipt and analysis of cell cultures agents for optical microscopy), biophysical (flow cytometry), statistics.RESULTS:
It was shown that cells in thyroid primary culture of offspring rats prenatally exposed by radioisotopes of iodine 131 signs of destructive degenerative changes were observed mostly when animals of both sexes were irra diated. Increased number of two and three nuclear cells and induction of ring like cells is an evidence of signifi cant genotoxic violation and points to the genome instability in offspring of animals exposed by radioisotope iodine 131.CONCLUSIONS:
Analysis and quantitative morphological parameters of cells in thyroid primary culture of newborn rats whose parents were exposed prenatally by radioisotopes of iodine 131 showed that upon exposure to radiation thy roid undergoes destructive changes at the cellular level and, even in the second generation of offspring, leads to disruption of its functions.Palabras clave
