[Cellular level of the body adaptation to the environmental exposure in the large industrial city (Saint-Petersburg)].

: By methods of light and electron microscopy structural disturbances of heart, kidneys, liver and pancreas were studied in rats pups who were born and kept for a year at kindergartens of city districts diverse in level of environmental pollution (air and soil). The content of micronuclei in epitheliocytes of oral mucosa in 5-6 ys old children from the kindergartens was controlled in order to detect chromosome aberrations. The examination of morphofunctional state of the organs studied and cells containing micronuclei carried out in different districts of the city allowed to reveal correlation between disorders studied and the level of environmental pollution.
