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).

摘要

长期生活在切尔诺贝利和基辅动物房的大鼠,其小肠上皮和基质细胞出现了可变的营养不良和坏死性变化。两组动物的这些变化及其动态没有主要差异。生活在切尔诺贝利且食用污染更严重食物的大鼠有一些特殊特征:隐窝黏液化生、上皮细胞凋亡、内皮细胞吞噬活性低以及致密上皮和毛细血管细胞增加(凝固性坏死类型)。
