title: [The morphological and ultrastructural changes in the small intestine of rats with long-term constant exposure to low doses of ionizing radiation].
abstract: Variable dystrophic and necrobiotic changes were revealed in epithelial and stromal thin intestine cells in rats who had been living for a long time in Chernobyl and Kiev animal houses. There were no principal differences of these changes in the both groups of animals and their dynamics. The rats that lived in Chernobyl and consumed more polluted food have some special features: crypt mucoidisation, epithelial cell apoptosis, low pinocytic activity of endothelial cells and increase of dense epithelial and capillary cells (coagulation necrosis type).
